Our Services

Home Insulation Lets You Live Comfortably

Foam Engineers’s home energy efficiency experts act like detectives to find out what is ailing your home. We use technologies like thermal imaging and manometers to find clues such as pressure differentials and pockets of hot air. With the evidence collected, we can diagnose the problems with your home and find a solution that works for you.

Our home insulation services will reduce your HVAC usage, reduce your energy bills, lengthen the lifespan of your heating and cooling systems, and lower the amount of moisture in the home — better protecting you and your loved ones from mold and bacteria growth.

“the home actually felt warm”

“Previously on cold days, the air coming out of the vents was luke-warm and the house just felt cold. After [Foam Engineers] performed their work, it was 15F outside and the ducts were still delivering hot air through the attic and the home actually felt warm.”

– Thomas T.

Attic Insulation Eliminates Major Headaches

Attics cause headaches for homeowners.  They retain much more heat and moisture than the rest of the home, leading to Stack Effect in both hot and cold months. Many homes in St. Louis were built without proper attic ventilation, leading to ineffective insulation and poor airflow. 

Ultimately, correcting your attic’s problems with ventilation and insulation will lead to a more comfortable living environment in the home by reducing temperature differentials. Finally, you can get the consistent temperature you want without running your systems constantly.

Finish Your Basement & Your Home with Basement Insulation

Often, homeowners call us when they need to finish their basement, but even homeowners who are not could benefit from basement insulation. Because basement walls are either directly exposed to the cold ground or the outside temperature, basements are much cooler than the rest of the home. It’s like living on top of an open refrigerator. 

Insulating a basement reduces the temperature difference between the basement and the living space. It can give you a livable space while reducing your home’s energy consumption!

“significant change in comfort”

“Paul Peterson was very informative explaining what I was interested in doing – spraying my basement rim joists. … I have really noticed a significant change in comfort in my home… not only in the basement, but also on the main floor. I plan to have Paul do additionally energy efficiency projects to my home in the near future.”

Crawl Space Insulation Protects 50% of Your First-Floor Air

A cold crawl space can put a drain on your home’s energy consumption and cause you discomfort as you struggle to get the right temperature in your living space. After all, about 50% of the air on the first floor came from the crawl space. The temperature difference between your crawl space and the house just makes this problem worse, as the warmer air will flow right out of your crawl space due to Stack Effect.

Our crawl space insulation is like an improved version of a crawl space encapsulation. We don’t just treat the symptom of condensation by installing vapor barriers and dehumidifiers.  We insulate to bring the crawl space temperature closer to that of the home, so condensation never forms and the air on both sides has less reason to move.

Stop Cooling the Whole Neighborhood with Air Sealing

If you are dealing with drafts, hot and cold spots, or an inability to heat or cool the living space to your liking, you may have a leaky house. Diagnostic tools like a blower door test and thermal imaging can tell us how bad the problem is and where the trouble spots are. The more leaks your home has, the more pronounced temperature differences will be.

Whether the problems are in your windows, ducts, attic, doors, or elsewhere, we can create a better seal for your home and reduce hot and cold air infiltration and exfiltration, making it more comfortable and energy efficient.

Find Costly Problems with an Energy Audit

If you are spending way too much money on your monthly electricity bill, you may need a home energy audit. Through a variety of methods like blower door testing, thermal imaging, moisture metering, and combustion safety testing, we can assess what parts of your home are a drain on your systems and your pocketbook.

An energy audit is often the first step in reducing your bills and your home’s carbon footprint. With an audit in-hand, we can find solutions that fit your home’s needs and your budget.

“don’t see why you would consider anyone else!”

“Very impressed with their knowledge, professionalism, and their customer service. If you’re considering an energy audit to determine how to best improve and upgrade your home’s energy usage and comfort level, I don’t see why you would consider anyone else.”

– Nick L, Fenton

Remove Ruined Insulation Safely

Insulation that has been exposed to water leaks, smoke, or fire damage can cause trouble for years to come. You may deal with unpleasant smells, ineffective insulation, or even mold growth. If you have suffered pest damage, then you could be exposed to feces, urine, or other contaminants. Do not let ruined insulation fester in your home.

We remove and replace insulation in the safest way possible, limiting the fallout from moving contaminated materials.

Proper Ventilation Fixes a Problem 90% of Homes Have

Heat and moisture build up in your attic, causing a temperature differential with the living space and increasing the risk of nasty side effects like mold, wood rot, and pest infiltration. Most St. Louis homes were built without proper ventilation, and installation issues plague attics in the area. We estimate that 90 percent of the soffit vents we see were incorrectly installed.

With proper mitigation measures, like gable fans controlled by temperature and insulation baffles, you can reduce your risk of moisture buildup, Stack Effect, and an unpleasant living environment.

“The A/C is finally not struggling”

“They did a fantastic job and our A/C is finally not struggling to keep the house cooled. The A/C now cycles off as it should and can quickly cool the house down. I would highly recommend them!”

– Krista D.

Restore Animal Damaged Materials & Impede Future Intrusions

Insulation is a tempting target for a lot of animals. Birds and rodents love it for nesting, and some animals even eat it. Unfortunately for you, the intrusion into the home exposes your insulation to the elements.  Once it gets wet, it will never return to its original form.

If you have critters tearing up your insulation, give us a call. We can repair the damage and replace your old insulation with animal-resistant insulation, making future intrusions much less likely.
