Blower Door Testing Cost: What to Expect and When It’s Worth It

Fri, 27 Feb 2026 15:33:44 GMT

How to Think About Blower Door Testing Cost and Value

Blower door testing cost for most homes in Pennsylvania typically falls in the range of a few hundred dollars, based on your home’s size. You’re probably here because something feels off. Parts of your house won’t stay comfortable. Energy bills keep climbing. Those frustrations often come from hidden air leaks around attics, exterior doors, windows, and wall cavities.

At Lantz Insulation, serving Lancaster County and Southeastern Pennsylvania since 1978, our trained technicians use professional diagnostic tools to pinpoint where air is escaping and clearly explain the next steps.

By the end of this page, you’ll understand what drives blower door testing cost, know whether air leakage testing is a practical next step, and how to achieve comfort throughout the year.

What’s Included in Blower Door Testing Services

Blower door testing answers a simple question. Where is heated or cooled air escaping from your home, and where is outside air getting in where it shouldn’t? Those leaks are often what cause drafty rooms, uneven temperatures, and rising energy bills.

Here’s what the process looks like, step by step:

Step 1: Quick setup at an exterior door. We place a fabric panel with a calibrated fan in a doorway, usually the front or back door. Setup typically takes a few minutes.
Step 2: We run the fan to create controlled pressure. The noise is noticeable but not overwhelming, similar to a box fan on high.
Step 3: We measure the rate of air leakage in your home. This shows how quickly heated or cooled air escapes and how much outdoor air replaces it through cracks and other openings around your home.
Step 4: We pinpoint leak locations. We use diagnostic tools like thermal imaging to find trouble spots like attics, basements, windows, ductwork, and wall cavities.
Step 5: You get clear takeaways. We explain what the results mean, which leaks matter most, and what fixes are worth doing first.

Most blower door tests take about one to two hours , depending on your home’s square footage, layout, and the level of detail in the testing.

Why Blower Door Testing Costs Vary From Home to Home

Blower door testing cost varies because homes don’t leak air in the same way. Size matters , since larger homes move more air and take longer to test and interpret.

Your home’s layout and construction matter too. Finished basements, multiple levels, or complex ductwork can require more detailed evaluation.

Do Older Homes and Newer Homes Leak Air Differently?

Yes, but for different reasons. Older homes often develop air leaks as insulation settles, breaks down, or was never installed evenly. Over time, the house itself also moves. Seasonal weather, wind, and temperature swings cause framing and foundations to shift slightly. As materials expand and contract, small gaps form, allowing outside air to slip in where insulation has weakened.

Newer homes can have air leaks, too, especially if insulation coverage is inconsistent or air sealing details were rushed during construction. The materials and build quality matter just as much as the home's age.

Neither type of home is better or worse by default. The causes differ, but blower door testing helps reveal where insulation and air sealing will have the greatest impact.

What Homeowners Often Get Wrong About Blower Door Test Cost

Mistake 1: Treating the test like a one-time purchase

Blower door testing isn’t something you buy just to check a box. The cost makes sense when the results guide real decisions. A cheaper test may confirm that air leaks exist, but it often doesn’t show which ones cause the biggest problems or where fixes will actually pay off.

At Lantz Insulation, we use blower door testing to prevent wasted upgrades. The goal is to help you fix the right problems first, not spend money chasing issues that won’t make a difference.

Mistake 2: Assuming all tests offer the same value

Some tests focus on speed and low cost. They deliver a number, then leave you to figure out the rest. More thorough testing costs more because it takes time to interpret results and connect them to comfort and energy use.

What actually matters

The cost of a blower door test pays for clarity. When testing shows where air leakage is hurting your home and why, you avoid guesswork and spend your budget where it delivers the best results.

How Lantz Looks at Blower Door Test Results

We focus on where air leakage is actually affecting comfort, energy use, and consistency from room to room. We’re not looking to fix everything. We’re looking to fix the right things.

Common Trouble Spots We See

Blower door results often point to a few repeat problem areas:

Attics with old, uneven, or ineffective insulation
Exterior walls with poorly insulated or empty cavities

Basement ceilings and rim joists where air leaks travel upward

These areas usually have the biggest impact on how your home feels day to day.

How We Decide What to Fix

Based on what the results show, we explain which insulation approach makes the most sense for your home.

Spray foam insulation seals and insulates gaps in hard-to-reach areas, making it especially effective for stopping air leakage at the source.
Cellulose insulation improves coverage and consistency in walls and attics, helping reduce drafts and stabilize indoor temperatures.
Applegate insulation offer a high-quality option for homeowners looking for durable, well-performing insulation backed by proven manufacturing standards.

Each option affects comfort and efficiency differently. We help you understand how they work, where they’re most effective, and what fits your home best.

You won’t get a report and a shrug. We walk through the results, explain priorities, and outline clear next steps so you can move forward with purpose instead of guesswork.

“The turnaround time through the whole process was exceptional. Definitely two big thumbs up working with Lantz Insulation.”

6 Ways Summer Attic Insulation Can KeepYou Cool and Cut Costs

mcgair@oostas.com (McGair Valois) — Tue, 08 Apr 2025 12:58:18 GMT

Keep your home cool with attic insulation

You know that attic insulation helps keep your home cozy in the winter, but did you know it’s just as effective in the summer? As outdoor temperatures rise, insulation blocks heat and humidity from seeping in, helping to keep the inside of your home cool and comfortable.

If you want to beat the heat and lower your energy bills, installing the right insulation can make all the difference. Wondering whether attic insulation helps in the summer? The answer is a resounding yes!

Here are six ways attic insulation can help your household this summer:

1. Lowering Cooling Costs

With insulation in place, your air conditioning system doesn’t have to work as hard, which results in lower energy bills.

2. Consistent Comfort

Proper insulation ensures every room in your house stays comfortably cool, eliminating those uncomfortable hot spots or overly cold areas.

3. Boosts Property Value

Energy-efficient homes with proper insulation are more attractive to potential buyers, increasing your home’s market value.

4. Protects Your Home’s Integrity

Attic insulation reduces moisture buildup, preventing mold, wood rot, and damage, especially during the humid summer months. It also helps lower the allergens circulating in your home.

5. Keeps Your Home Energy Efficient

Keep your cool all season long—summer insulation helps your home stay energy efficient and your energy bills low.

6. Blocks Heat Buildup

Attic insulation stops your roof from getting too hot, driving down costs and relieving your HVAC system constant pressure.

Big picture: How does attic insulation help in the summer?

A broiling attic can leave you and your bank account sweating through Labor Day. Without proper insulation, heat from your roof seeps into your living spaces, making your AC work overtime. Attic insulation acts as a thermal barrier, slowing heat transfer and keeping your home cooler with less energy use.

The effectiveness of insulation is measured by its R-value, which indicates how well it resists heat flow. The higher the number, the better the insulation can block summer heat and retain warmth during the winter.

In Lancaster County, PA, where summers bring consistently muggy temps, the U.S. Department of Energy recommends attic insulation with an R-value between R-49 and R-60. This level of insulation helps maintain a steady indoor temperature, reduces cooling costs, and keeps your home comfortable all season long.

How attic insulation helps your home during the Summer months

Attic insulation does more than keep you warm in the winter. In the summer, it plays a critical role in reducing heat transfer, lowering cooling costs, and improving comfort on every floor. From boosting air quality to preventing heat buildup, here’s how insulation helps your home all season long.

Drives cooling costs down 20%

Proper attic insulation helps maintain a cool indoor environment and can reduce cooling costs by up to 20%. With less reliance on your AC, your energy bills drop accordingly. Savings can even be higher depending on your home’s location, materials, and age.

One homeowner shared , “ Our energy bill was cut in half after insulating our attic. It made a huge difference .”

A cooler and more comfortable home on all floors

Attic insulation helps maintain a consistent temperature throughout your home. Homeowners often notice the second floor feels cooler in summer with proper insulation, avoiding the uncomfortable heat that tends to rise.

One homeowner shared their experience: “Now that it is getting warm enough to really need the AC, I’ve noticed that the house is pretty comfortable with the thermostat set at 75, rather than 72/73 like we used to set it, and it ran nearly constantly on very hot days.”

Higher property value

Attic insulation isn’t just about comfort—it’s an investment in your home’s value. A well-insulated attic signals to potential buyers that the home is energy-efficient and well-maintained.

One homeowner pointed out how insulation plays a role in resale value: “There will be impact in the property value. The state of the insulation or lack thereof will show in an inspection report, and the buyer will have to decide if it’s in their budget to improve or to pay for the extra power to heat.”

Homes with proper insulation are more attractive to buyers, potentially leading to higher resale values and faster sales.

Superior indoor air quality

Attic insulation helps prevent moisture buildup, reducing the risk of mold and mildew—two common culprits of poor air quality. It also seals off gaps where pollen and outdoor allergens can enter your home.

Replacing old insulation in older homes can further improve air quality by removing outdated materials that may harbor dust, debris, or contaminants, ensuring cleaner, fresher air throughout your home.

Decreases carbon footprint

Upgrading attic insulation reduces energy consumption, lowering your home’s carbon footprint. Eco-friendly insulation options like cork, cellulose, and sheep’s wool not only boost energy efficiency but are also made from natural and often recycled materials.

These sustainable choices improve comfort and reduce environmental impact, helping you create a greener, more energy-efficient home.

Prevents heat buildup

Proper attic insulation acts as a barrier against heat buildup, keeping your home cooler and reducing strain on your HVAC system. Without it, heat seeps through the roof, raising indoor temperatures and forcing your AC to work harder.

Sealing air leaks and improving ventilation further prevent excess heat. Soffit and ridge vents allow hot air to escape, while radiant barriers reflect solar heat away.

Summer is the season to insulate your home

If you’re considering new attic insulation, summer is one of the best times to do it, especially if you live in Climate Zone 5, which includes Lancaster County, PA. Insulation materials like spray foam are best applied when temperatures stay consistently above 50 degrees Fahrenheit. In the summer, stable conditions allow the insulation to seal properly, ensuring long-term performance.

With temperatures often ranging between 70–90 degrees, it’s also the time when your home needs insulation the most. Installing now means you’ll immediately benefit from lower cooling costs, improved energy efficiency, and more consistent comfort.

Dry summer weather also helps avoid delays or complications that can come with colder or wetter conditions earlier and later in the year

The best time for spray foam insulation in Lancaster County

The International Energy Conservation Code (IECC) divides the U.S. into eight climate zones based on factors like temperature, humidity, and seasonal changes. Lancaster County, PA, is located in Climate Zone 5 on the IECC climate zone map. This zone includes areas that experience both cold winters and hot, humid summers, making the need for effective insulation even more important.

Due to its high R-value, spray foam insulation is ideal for the Zone 5 climate. Not only does it resist heat transfer, but it also seals air leaks, preventing moisture buildup caused by wet and humid conditions. Summer is the best time for installation, as warm outside temperature allows the foam to cure and adhere properly.

Some signs of poor attic insulation during the summer

If your home feels unbearably hot no matter how high you crank the AC, something’s not right. Your attic insulation (or lack of it) might be to blame!

Overheating top floors

When your upstairs feels like a sauna, it’s almost impossible to sleep, relax, or even think clearly. Poor insulation lets heat pour in from the roof, making upper floors especially uncomfortable during the summer months.

Overworked HVAC system

When your A/C is forced to run nonstop, it’s not just wasting energy — it’s wearing down fast. Poor insulation forces your system into overdrive, making breakdowns and surprise repair bills more likely. Nothing kills your summer vibe like a hot house and an emergency HVAC call.

Mold and moisture issues

When insulation fails, warm air and humidity can creep in — and that’s when the funky smells start. Mold and mildew thrive in damp attic spaces, bringing musty odors and potential health risks like allergies and respiratory irritation. No one wants their home to smell like summer humidity, let alone breathe it in.

Drafty rooms

In the summer, a drafty room isn’t refreshing — it’s frustrating. Poor insulation lets hot air sneak in and cool air slip out, creating uneven temperatures and that constant battle over the thermostat. You’re left sweating in one room and freezing in another, wondering why your home never feels quite right.

Think you have air leaks in your home?

Blower door testing is a special service Lantz Insulation offers to pinpoint air leaks with precision. Unlike traditional methods, our blower door test uses real data to identify leaks, allowing you to address the exact problem areas. This means more effective solutions, lower energy bills, and a more comfortable home.

Why it matters:

Air leaks waste energy, overwork your HVAC, and make your home less comfortable. Our blower door test gives you real data to make smart improvements that actually pay off.

Types of insulation for the summer season (and how to choose)

When it comes to insulating your home for the summer, you have several options based on your budget, home type, and local climate. Each type of insulation has its advantages, and the right one depends on your efficiency needs and how much you’re willing to invest.

Spray foam insulation

Best for: Maximum energy efficiency

Spray foam insulation expands to fill gaps, providing an airtight seal that prevents heat from entering. This makes it ideal for homes needing top-tier energy efficiency. It also prevents moisture buildup, reducing the risk of mold. It’s a more expensive option but it offers long-term savings on energy bills.

Cellulose insulation

Best for: Eco-conscious homeowners

Cellulose insulation, made from recycled paper and other sustainable materials, is a cost-effective and environmentally friendly option. It provides excellent thermal protection and is simple to install, especially in attics, keeping your home cool in the summer. It also performs well in soundproofing.

As one homeowner who installed cellulose put it: “Cellulose is probably the earth and user friendliest, and fairly inexpensive, but it’s sensitive to moisture.”

Blown-in fiberglass insulation

Best for : Easy installation and cost-effectiveness

Blown-in fiberglass is a budget-friendly option that’s easy to install, especially in existing homes. It can be added to existing insulation to boost performance. Though it doesn’t offer the same airtight seal as spray foam, it still provides solid temperature control and helps with energy efficiency.

Radiant barrier insulation

Best for: Homes with significant heat from the roof

Radiant barriers reflect heat away from your home, making them perfect for preventing heat buildup in attics. This insulation is ideal for homes with significant exposure to the sun. It’s typically installed in combination with other insulation to maximize cooling efficiency.

Each type of insulation has its own set of pros, so choosing the right one depends on your home’s specific needs and your budget.

What if my attic is partially insulated already?

Even if your attic is partially insulated, it’s important to check for gaps or thin areas where heat can seep in. Insulating these spots will help maintain consistent temperatures and improve energy efficiency.

Keep in mind that insulated and non-insulated rooms sharing walls can result in heat transfer, affecting comfort in other parts of the home. Upgrading or adding insulation ensures your home is better protected from heat fluctuations and reduces energy loss.

If you live in an older home, it’s also important to ensure the current insulation is in good condition and hasn’t pulled away from the walls or resettled.

Choosing the right R-value for the hot summer climate

What is R-value?

R-value measures an insulation material's ability to resist heat flow. A higher R-value means better insulation performance, improving temperature control and energy efficiency. R-value depends on the insulation material, thickness, and density—generally, the thicker and denser the material, the higher the R-value. Insulation type also influences R-value, with spray foam and foam board typically offering the highest performance.

What R-value do you need for summers in Lancaster, PA?

In Central Pennsylvania (Climate Zone 5), attic insulation typically needs an R-value between R-38 and R-60. The exact thickness will vary depending on the insulation material.

For spray foam, which provides an R-value of about R-6 per inch, you would need approximately 6-7 inches to reach R-38. For blown-in fiberglass insulation, with an R-value of around R-3.5 per inch, you'll need about 10-17 inches to meet the R-38 requirement.

For best results, it's essential to consider the insulation type's specific R-value per inch when determining the ideal thickness. This ensures your home stays energy-efficient, with reduced cooling costs and better overall comfort during the hot summer months.

Summer insulation FAQs: What every homeowner needs to know

7 Ways Attic Insulation Keeps Your Home Warm in Winter—and Saves Money

Mon, 10 Feb 2025 20:18:34 GMT

How attic insulation helps in winter

Faulty attic insulation can let a quarter of your home’s heat escape through your roof, leading to high energy bills, cold spots, and even roof damage.

Here are some ways attic insulation can help your household this winter:

Slowing heat loss through the roof
Keeping the temperature consistent in every room in your house
Cutting down on energy costs by 20%
Supporting your HVAC system
Getting rid of cold spots and winter drafts
Eliminating ice dams and roof damage
Reducing noise and humidity

Investing in professional-grade attic insulation can help improve your quality of life and cut down on costs for the coming winters. Let’s do a deep dive on the benefits of attic insulation during the winter season and find out what insulation method is best for your home.

Lantz Insulation is Lancaster County’s trusted insulation authority, providing homes new and old with effective insulation since 1978.

7 ways attic insulation keeps your home warm in winter

1. Reduces heat loss through the roof

Did you know that approximately 25% of your home’s heat loss occurs through the ceiling? That’s compared to 35% seeping through your walls, windows, and doors, and 10% sinking through the floor.

Attic insulation slows heat transfer during winter by reinforcing your home's thermal envelope—the structure that separates indoor air from outdoor air. With proper attic insulation, you can ensure that you’re not losing essential heat during the colder months.

2. Stabilizes room temperatures across floors

If your attic isn’t properly insulated, you may notice that your 2nd floor is always significantly hotter than your 1st floor. To understand why this happens, it’s important to know that hot air will always flow towards cold air - the law of thermodynamics .

In your home, hot air will continue to flow towards cold air until there is no temperature difference. In the winter, proper attic insulation stabilizes your home’s temperature by minimizing heat loss through your ceiling. As the heat is contained by your attic insulation and released into your home via your heating system, the temperature stabilizes across floors.

3. Cuts energy bills by

20%

According to the Department of Energy , proper insulation can reduce your heating and cooling costs by 20%! By reducing the amount of heat leaking through your ceiling, attic insulation reduces the workload placed on your HVAC system during the harsh winter months.

With less heat being released through your ceiling, your energy system can operate more efficiently, reducing the financial burden on you and your family. One study found that the insulation typically pays for itself within six years!

4. Stabilizes room temperatures across floors

5. Prevents winter drafts and cold spots

If you’re dealing with frigid rooms or floors in your house during the winter, it might be because of poor insulation. Without an effective thermal envelope, your house will struggle with maintaining consistent temperatures throughout all of your rooms.

Homeowners who insulate their attics often see their home’s cold spots disappear.

“I had the insulation blown into my attic and let me tell you what, my upstairs is so warm in the winter compared to without that added insulation,” one homeowner commented .

“I'm able to keep my thermostat at 62 degrees during winter months after insulation. Before insulation I had the thermostat at 72 degrees. Huge difference. My energy bills are half of what they were.”

6. Eliminates ice dams and roof damage

As winter progresses, especially in colder climates, you may start to notice large swells of ice gathering on your gutter and hanging off from your roof. Those are called ice dams, occurring as heat released from your home melts heavy snow buildup during the day and then freezes during the night.

As the ice builds up at the edge of your roof, it traps a reservoir of water behind it, driving water back up your roof and under the shingles. This can lead to water damage or leaks in your home.

Removing ice dams should be done carefully using methods approved by contractors, as haphazard removal methods can lead to injury.

Effective attic insulation can cut off the release of heat from your home to your roof, cutting down on rapid ice melting and freezing. Investing in quality attic insulation reduces your home’s risk of accumulating ice dams and taking on roof damage.

7. Improves comfort, noise levels, and humidity control

Insulation materials like cellulose and spray foam insulation have sound-dampening properties that help reduce environmental noises like rainfall, traffic, wind, and more. Beyond that, it can improve the acoustic environment of your home, cutting down on echoes and containing the noises within your home.

Attic insulation also helps reduce humidity by regulating your home’s temperature, creating dry indoor conditions that prevent mold and moisture.

One homeowner noticed an immediate difference in their home after installing cellulose insulation.

“I had blown-in cellulose insulation added to the floor and stairs of the walkup attic in my 1867 Victorian. Noticed an immediate improvement in comfort,” they said.

“The house was quieter, humidity levels were more stable. Overall the house felt tighter, more solid and sheltering.”

Have an older home? You might see huge gains from attic insulation.

If you’re a proud owner of a historic home or building, investing in insulation for your attic may lead to major cuts in energy costs for you and your family. Older homes may excel in charm and character, but they often lack in energy efficiency .

While today’s homes must be fully insulated, that wasn’t always the case. It was only as recent as 1965 that U.S. building codes required insulation, and even then it was only required in the walls.

How to evaluate if your older home needs attic insulation

1. Check if your home is insulated

Depending on the year your home was built, it may not have been insulated or insulated properly. Check your attic for signs of insulation and decide if you need to add some.

2. Inspect your old insulation

As insulation ages, it may be destroyed by pests or fall victim to water damage. Inspect your old insulation for signs of damage and consider replacing it.

3. Evaluate your home for drafts

Using a blower door test , you can check your home for drafty attics or other air leaks. The data gathered during a blower door test is great for assessing how you’ll need to insulate your home.

Types of attic insulation for winter (and how to choose)

As the cold creeps in, it’s important to choose the right insulation material for your home. Different types of insulation serve different needs, so understanding your options can help you make the best choice for your home and climate.

Spray foam insulation

Spray foam insulation is great for attics because of its high R-value, duration, and resistance to moisture. As the insulation is sprayed into your attic, the foam expands and fills unconventional spaces. This also makes it perfect for filling cracks and sealing off air leaks.

“We had spray foam insulation added to the attic at our last house,” said one satisfied homeowner. “It was oil heat so we had a great way of measuring the efficiency. It made a big difference in both summer and winter.”

Blown-in fiberglass insulation

Blow-in fiberglass insulation is made of small glass fibers that are considered “loose-fill” insulation due to its fluffy appearance. Fiberglass insulation excels in affordability and ease of installation but is not as airtight as a material like spray foam.

As the fluffy insulation blow-in fiberglass compacts, it may decrease in effectiveness, so it’s important to monitor your home’s efficiency every few years.

Cellulose insulation

Cellulose insulation is made from recycled paper, perfect for homeowners looking for sustainable solutions. It has a higher R-value than fiberglass insulation and can be used to fill both old and new attics to contain heat and reduce noise.

Cellulose is also great for reducing mold and deterioration, as it restricts air movement that can bring moist air into wall cavities and attics.

“My house got 2 ½ ft of cellulose,” said one homeowner who installed cellulose insulation. “Comfort was a bit better, not by a lot, but my utility bill dropped, probably paid for itself in 2 years.”

Radiant barrier insulation

Radiant barrier insulation is designed for homes in warm or temperate climates that don’t require stronger insulation. These lightweight, reflective panels are often used as temporary measures until more substantial insulation is installed.

For the colder climates that we typically service at Lantz Insulation, we would recommend more traditional insulation (like cellulose and spray foam) over radiant barrier insulation.

Choosing the right R-value for your climate

R-value is a measure of insulation’s effectiveness, measured in R-values per inch of thickness . An insulation’s R-value tells you how well it keeps heat from leaving your home. The R-value you need depends on your climate and the space you’re insulating. It’s also an additive measurement, meaning that two pieces of R-10 stacked on top of each other make R-20, two pieces of R-20 make R-40, and so on.

Energy Star and the EPA make different R-value recommendations for different climates. Typically, colder climates require R-values between R-49 and R-60 for attics, R-38 to R-49 for moderate climates, and R-30 to R-38 for warm climates.

Which R-value is right for Pennsylvania?

For attics in Lancaster County and most of Pennsylvania, it is recommended to apply an R-value of R-60 if your attic has no insulation , and R-49 if you have three to four inches of attic insulation already.

DIY vs. professional installation

If you’re big on doing home improvement on your own, you may be wondering if it’s worth trying to save the money on installing insulation and doing it yourself. To help you decide, here are some things to consider about both DIY and professional insulation.

DIY installation

The DIY solution is great for homeowners on a budget who have done the necessary research on their home, building codes, insulation material, installation equipment, and safety gear.

Pros

Avoid labor costs by doing it yourself
Flexible insulation scheduling
An easy solution for smaller projects with less overhead

Cons

Learning proper installation technique
May take longer to install for beginners
Risk of injury without proper training or equipment
Risk of mistakes that can lead to fires, mold, or ice dams.

Professional insulation

Professional insulation is a solution for homeowners willing to pay a larger upfront cost to ensure their home is insulated according to building regulations, or for those looking for help with complex projects.

Pros

Installation that meets building codes
Rely on experienced professionals for your insulation needs
Professional insulation is typically installed faster
Better for dealing with large or complex projects

Cons

Higher labor costs
Less control over the installation process

“Lantz Insulation came out to our house in mid-December and inspected the crawl space we were considering insulating. They provided a quote with a few options a couple days later which was very competitive. The price of the insulation, including the install, was around the same price for me to purchase it and do the work myself. A couple weeks later they came out and did the work and everything turned out awesome.” — Brad B.

Rebates and tax credits for attic insulation

Did you know you can get tax credits for properly insulating your home’s attic? According to the Department of Energy, most bulk insulation projects involving batts, rolls, blow-in fibers, rigid boards, expanding spray, and pour-in-place qualify for a credit that lets you claim a portion of the project’s cost.

You can claim 30% of your insulation project’s cost with a maximum credit cost of $1,200 for improvements to your home’s envelope. To claim the credit, you must install insulation on your primary residence, which must be in the United States. Homeowners can claim their tax credit using IRS Form 5695.

How can I tell if I need to upgrade my attic insulation?

Are you encountering issues heating your home? Struggling to get your energy bills under control this winter? Not sure when to upgrade your attic? Here are a few signs it's time to get new insulation for your home.

Heating bills are higher than normal

If your energy costs have been steadily climbing, poor insulation could be to blame. Insufficient or damaged insulation allows heat to escape, forcing your heating system to work overtime.

Cold drafts and uneven room temperatures

Do some rooms in your home feel colder than others, no matter how high you turn up the heat? Inconsistent temperatures are often a sign of inadequate insulation that fails to regulate airflow and heat distribution.

Snow melts off your roof faster than your neighbors’

A roof that sheds snow too quickly may be losing heat through the attic. Proper insulation acts as a barrier, keeping warm air inside your home and preventing it from escaping through the roof.

Insulation appears flattened, damaged, or missing

Visible signs of wear, such as compressed or missing insulation, significantly reduce its effectiveness. Moisture damage, pests, or aging materials can all compromise your attic’s thermal performance.

Common questions about attic insulation for winter

How long does spray foam insulation last?

annie@oostas.com (Annie Volpe) — Fri, 28 Jun 2024 14:42:55 GMT

How long does spray foam insulation last? When properly applied, spray foam insulation can last between 80 years to 100 years, making it a long lasting and reliable solution. Its longevity comes from its moisture resistance, ability to withstand temperature changes, and lack of settling.

We'll dive deeper into this topic below, reviewing the advantages of installing spray foam, how it measures against other types of insulation, and more.

Why does spray foam insulation last so long?

There are a variety of reasons for spray foam insulation’s long-lasting qualities, from its chemical composition to the application process itself. Let’s explore further with a couple of frequently asked questions.

Factors that can influence the lifespan of spray foam

Like anything else, various factors influence the lifespan of spray foam insulation, each contributing to the material's long-term performance and durability.

Installation quality

The main reason spray foam insulation deteriorates is incorrect installation, such as incorrect foam thickness and leaving holes in the insulated space. Proper application by experienced professionals ensures the foam adheres correctly to surfaces, expands uniformly, and creates an effective seal. Poor installation can lead to gaps, uneven layers, and reduced insulation efficiency.

Environmental conditions

Another critical factor affecting the foam's durability is environmental conditions. Extreme temperatures and frequent temperature fluctuations can impact the integrity and performance of the insulation. High humidity and exposure to moisture can also affect certain types of spray foam, particularly open-cell foam, which is more prone to water absorption.

Spray foam maintenance tips

Preventive maintenance is key to maximize the longevity of spray foam and to ensure it’s performing to the best of its ability. It’s important to conduct routine inspections of spray foam insulation, particularly in areas susceptible to moisture or physical damage.

If you detect damage or deterioration, contact a professional. Small repairs can prevent broader issues from developing, ensuring the insulation remains effective over time.

Comparing lifespans: spray foam vs. other insulation materials

There are a slew of insulation materials available, some of which include:

Fiberglass

Fiberglass insulation is one of the most used insulation materials in residential and commercial buildings. Fiberglass insulation is very fine glass fibers woven into a fluffy, wool-like material. It comes in various forms, including fiberglass batts, rolls, and loose-fill, making it versatile and easy to install in attics, walls, and crawl spaces.

Cellulose

Cellulose insulation is an eco-friendly and highly effective insulation material made predominantly from recycled paper products, such as newsprint. It’s typically installed by blowing it into wall cavities, attics, and other hard-to-reach areas, allowing it to conform to irregular spaces and create a dense, insulating layer.

Wool

Wool insulation is a natural and sustainable insulation material known for its excellent thermal and acoustic properties. Derived from the fleece of sheep, this type of insulation is gaining popularity for its eco-friendly nature and low environmental impact and is available in batts and rolls.

Is spray foam worth the investment?

Absolutely! The initial cost of spray foam insulation can be higher than other kinds of insulation because of the cost of the material itself and the need for professional installation. Despite this, the long-term energy savings and potential reduction in maintenance costs justify the investment.

Plus, when your home is well-insulated, you create a more consistent indoor climate, reducing the workload on your heating and cooling systems, lowering your energy bills.

Enhance home value and efficiency with long-lasting spray foam

Spray foam insulation stands out as a top solution for residential properties because of its unique combination of efficiency, durability, and versatility. Its ability to expand and conform to any space means that every nook and cranny is properly insulated, eliminating gaps and thermal bridges that can lead to heat loss.

Also, spray foam can reduce the costs of electric heating and cooling by up to 50 percent. This substantial reduction in energy consumption is mainly due to the superior insulating properties of spray foam, which create an airtight seal that significantly limits heat transfer.

How to Add Spray Foam Insulation in Existing Walls

In order to install spray foam insulation in an existing wall, you start by creating several small holes—one inch in diameter or less—and inject the spray foam into the cavity of the wall. Then, the spray foam will begin to expand, filling all of the wall’s crevices.

When everything finishes expanding, the foam hardens and becomes a durable insulation material. Additionally, it adapts to fit the contours of the cavity , ensuring complete and secure filling and sealing.

Before you start adding spray foam insulation to an existing wall, we recommend consulting with a professional like us, so we can provide advice tailored to your situation and get the best possible insulation solution.

When Should You Avoid Spray Foam in Walls?

While spray foam insulation offers numerous benefits, there are certain situations where it may be advisable to avoid using it in walls, including:

Moisture Issues : If the existing walls have a history of moisture problems, such as water leaks or high humidity levels, spray foam insulation may not be the best choice. Moisture can become trapped within the walls, leading to potential mold growth and damage. Before applying spray foam insulation, it's important to address any underlying moisture issues and ensure proper ventilation.

Structural Issues : If the walls have structural problems, such as significant movement, cracking, or instability, it is crucial to address these issues before installing spray foam insulation. The foam's expansion could exacerbate existing structural problems or hide underlying issues, making it difficult to identify and rectify them in the future.

Electrical Wiring Concerns : When considering spray foam insulation, it is essential to ensure that electrical wiring within the walls meets code requirements and is properly installed. Improperly installed or inaccessible wiring can pose fire hazards or create difficulties when they need repairs or modifications.

Of course, you can address all these issues before foam insulation on existing walls and proceed with your project.

How Much Does It Cost to Foam Insulate Existing Walls?

The cost to foam insulate existing walls can vary depending on various factors such as the size of the area, location in the home or building, and thickness of the insulation.

It’s more expensive than other kinds of insulation, but its long-lasting design ensures it can last up to 80 years when properly applied and maintained! To find out more about the cost and other available options, give us a call to schedule a free estimate.

Advantages of Spray Foam Insulation

Spray foam insulation comes with a slew of benefits, some of which include:

Enhanced Energy Savings : Spray foam insulation creates an airtight seal, reducing air leakage and preventing drafts. This helps minimize heat transfer, resulting in improved energy efficiency and reduced heating and cooling costs.

Increased Comfort : By sealing gaps and cracks, spray foam insulation eliminates cold spots and hot spots in your home, providing consistent indoor temperatures and enhanced comfort throughout the year.

Long-Term Durability : Spray foam insulation is known for its longevity. Once applied, it adheres firmly to the walls, maintaining its effectiveness for many years without sagging or settling.

If that wasn’t enough to make the case for spray foam insulation, NASA’s Marshall Space Flight Center used this method for a launch vehicle stage adapter.

How We Handle Insulation in Existing Walls at Lantz

At Lantz, we don't use spray foam insulation for existing walls, instead we retrofit cellulose insulation as our go-to solution. We find that for most of our customers, retrofitted cellulose works well to maximize insulation in existing wall cavities while minimizing any complications that may arise from hardening foam in those cavities. For example, cellulose contours nicely around any existing pipes, wires, or other materials for a tight yet flexible seal.

We create 2 to 2-inch holes in each cavity, which are then strategically placed throughout the wall or attic to ensure proper coverage and distribution of the insulation. The holes are sealed after the insulation is installed.

Retro-fit cellulose, which we specialize in here at Lantz Insulation, refers to the process of adding cellulose insulation to existing structures or retrofitting insulation in walls, attics, or other areas. Cellulose insulation is made from recycled paper and treated with fire retardants, making it a sustainable and environmentally friendly option.

Benefits of Retro-Fit Cellulose

As with spray foam insulation, retro-fit cellulose insulation has an array of advantages, such as:

Energy Efficiency : Retro-fit cellulose insulation, when installed in walls, ceilings, or floors, can help reduce heating and cooling costs. It provides excellent thermal performance and helps maintain a consistent indoor temperature.

Cost Savings : By improving the energy efficiency of a building, retrofit cellulose insulation can lead to significant cost savings on utility bills over time.

Soundproofing : Cellulose insulation is known for its sound-absorbing properties. When used in retrofit applications, it can help limit exterior noise intrusions as well as reduce noise transmission between rooms.

Eco-Friendly : Retro-fit cellulose insulation is typically made from recycled paper, making it an environmentally friendly choice. It helps reduce landfill waste while providing effective insulation.

Trust the Spray Foam Professionals at Lantz

Existing wall spray foam insulation is a very effective technique that will help in a variety of ways, including comfort, durability, and lowering the carbon footprint. Spray foam insulation in existing walls is a viable option with many advantages.

Top 5 Places to Add Insulation

Tue, 09 Aug 2022 14:10:17 GMT

Are you among the lucky few who just bought or built a new home?

If so, congratulations! In this crazy market, you truly lucked out! You're in for many years of happy living.

But before you start unpacking, there are a few things you need to do to get your new house ready for occupancy. While you may be excited to crack open a can of paint or start arranging furniture, one of the most important things to add is insulation. If your home doesn’t already have insulation, now is the perfect time to add it.

As your local insulation specialists, we can tell you that insulation is absolutely essential for comfortable living. Whether you’re trying to keep your home cool or warm and toasty, insulation is the key to regulating your home’s internal temperature.

In addition to temperature regulation, insulation helps you save money on energy bills! Without insulation, your hard-earned money practically flies out the doors and windows. When your internal temperature is regulated, your central heating and cooling systems don’t have to be constantly working to maintain a comfortable temperature. As a result, you save boatloads of money.

The process of adding insulation is a massive project to take on. And installing it everywhere may seem like an overwhelming task. However, insulation doesn’t need to be installed everywhere. Instead, there are five prime areas of your home where insulation should reside.

The Attic

Insulation in the attic is one of the most important places to have it. Attic insulation can be especially beneficial in the colder months, as heat always rises above the cold. Without proper insulation, heat could escape up through your roof, resulting in your heating system working harder to keep you warm.

Windows and Doors

Adding insulation around your windows will help keep out the cold in winter and keep your home cooler in summer. All around, insulation is essential around windows and doors. As previously mentioned, without insulation in these areas, your money will practically fly out your windows and doors.

The Basement

If you have a basement, ensure it's well-insulated to keep out moisture and prevent freezing pipes during winter . Frozen pipes are another way you could potentially lose a lot of money, so make sure that your basement is insulated.

Walls

Adding insulation to your walls is a great way to prevent drafts and keep your home comfortable year-round . Again, adding to your walls could be a huge project to take on, but it is definitely worth it!

Between Finished and Unfinished Areas

If you have an unfinished basement or crawlspace, be sure to add insulation there as well. This will help regulate the temperature of those spaces and keep them from becoming too cold or too hot.

Adding insulation is the difference between comfortable living and, well, uncomfortable living. Protect your wallet and your loved ones through the Lantz Insulation specialists. We don’t just service insulation in Lancaster, PA, so contact us today to see if we service in your area. Our company has been trusted by central Pennsylvania for many years, installing insulation safely, carefully, and correctly.

With Lantz, you won’t have to worry about taking on such a vast project. Instead, just sit back and let us do the work for you, so all you have to do is get comfortable!
