Central Illinois insulation did a great job insulating our old home with spray foam insulation. Tim and his team were thorough during their application and used a thermal camera to find areas that needed touch ups. They collaborated with Todd at Midwest Building Performance to find the best solution for our house. We had a dramatic improvement in our blower door test after the insulation and couldn't be happier with the results. Tim was patient, knowledgeable, and had recommendations about what to look for as we considered future improvements to our house, such as installing a radon system through the insulated roof. I highly recommend Central Illinois Insulation.

Central IL Insulation did an outstanding job mitigating our attic ventilation and insulation issues as well as crawl space & basement insulation, and installed a new bathroom vent. Tim and his team are honest, professional, and prompt. They answer all of your questions and work with you to get to the right solution for your home. I would highly recommend this company to anyone needing insulation work.

Derek Henricks★★★★★5 months ago

Tim and his team did a fantastic job improving our attic and crawl spaces. They took several days to haul off old insulation in our attic, air seal, and blow in new insulation. Every step of the way, their customer service and quality of service make me eager to recommend this company.

From the moment I met Brad Johnson I knew I was in good hands. After a home consultation, Brad clearly advised with me on all the different furnace, AC and air filtering options that were available. After making my choices, the system was booked in for installation within 10 days. It was efficiently and affectively installed by Curtis and Ben within a day. Everyone I worked with on this was extremely professional. Thanks AAA Northgate.

Kyle Mitchell★★★★★3 weeks ago

Marcus did a great job! He has exceeded my expectations and performed his job in a very efficient and professional manner. He explained to me on the service he performed on my heating/cooling system, and gave me a few tips on my furnace filter. Thank you Marcus, I appreciate your help today. I recommend AAA Northgate. You deserve 5 ⭐️'s Kyle M

I recently had my HVAC replaced by AAA Northgate, and the entire process went very smoothly. Brandon responded quickly to my request for a proposal, and was happy to provide options. Suzanna was great to work with, and very responsive to communication for scheduling and payment. Curtis & Ben were my Technicians, and they worked quickly and efficiently to get my work done in a very professional manner. Overall I was very impressed by AAA, and would definitely recommend them.

jeff kriz★★★★★3 years ago

Very pleased with work pcb insulators performed. i had a 2000+ sq. ft. attic with 20' vaulted roof insulated/spray foamed. This was a 7 day job for a crew of 2-4 people. Professional, attention to detail, kept rest of house clean, long hours/hot environment - all exceptional. I'd say it was 98% perfect. What you see in the pictures is the install of IR reflective panels with closed cell foam insulation sealing/overlay. I'd recommend this company without question.

Collin Krause★★★★★3 years ago

I had a great experience with PBC insulators. The sales person Cole was extremely friendly and helpful throughout the entire experience. Cole was able to give us a quote within 10 minutes of inspecting our attic. PBC insulators sent their crew out within two days and insulated my entire attic in six hours. We are extremely happy with their thorough work. The team was very professional and mindful to take care of our old and unique house. Both of the technicians were also extremely friendly. I would highly recommend this company to any homeowners in the Peoria area who are looking to save on energy costs with the expected increase in rates.

Stephanie Gehrig★★★★★5 years ago

I wanted to take a second out of my day to say that calling PCB Insulators is always such a great experience because their appointment center manager, Cheyenne, is always so happy and cheery to speak with. You can literally hear her smiling through the phone. I spend all day long on the phone with clients and contractors alike, and a happy, friendly voice on the other end speaks VOLUMES for business. PCB, you got a good one.

Had our basement concrete block walls spray foamed with insulation from Energy Home Insulation. We are now enjoying every moment in our basement in a nice warm sealed basement thanks to Energy Home Insulation. I would highly recommend them for your spray foam insulation needs.

Harold and Sergio were the worker's that came to our home from: Energy Home Insulation Harold and Sergio were ontime both days, listened to what we wanted done and did a very thorough job. They both are very careful, caring and polite workers. They took their time to put up plastic and did a fantastic job. They even took the time to clean the garage door after the sprayer gun malfunctioned. Harold and Sergio also cleaned up the areas they had been in and even brought in the few items that I set outside the garage so the job could be completed. We are so thankful for the work and worker's Harold and Sergio. The job was stress free for us. Great company, impressive work and even more impressive is how great the worker's were. Our home is definitely warmer. Thank's Energy Home Insulation for doing such a wonderful job!!!! The Hemminger's

Energy Home Insulation insulated my attic and walls of my house. They had to reschedule due to Covid but were able to reschedule in a timely manner, and kept me informed throughout. The crew was friendly and careful, especially after the surprise hole to the inside of my house! They cleaned up everything very well.The bill matched the estimate. My house is more comfortable. I highly recommend them.

This company provided services for my home through a HUD program. They replaced my furnace, Central air unit, hot water heater, blew insulation in my attic, replaced my exhaust fan in the bathroom, cleaned my gutters and put shields on them to keep out leaves and dirt and installed a railing going down in the basement and a railing on the side porch. The contractors were very efficient, friendly and professional. I would recommend them for any work projects needed.

Josh Wieland★★★★★3 years ago

Kevin and his team were great. We had a few companies come out for quotes and they just measured and sent a quote. Kevin offered explanations for everything he was doing and was honest about what made sense (even if it meant not doing as much work). He was a great communicator and was always on time. They offer great incentives through Ameren that help out the cost which helps immensely. Come install day, that team was also on time and they came in, started to work, and were out. They were very respectful and cleaned up after themselves. When comparing to other companies in the area...I would highly recommend at least having these guys out to take a look if you're undecided!

Lisa Barry★★★★★4 years ago

Green Homes evaluated our energy efficiency and supplied corrective measures to improve insulation, electricity usage and temp control. We are very happy with the results. Our home stays warmer at a lower setting in the winter and cooler at a higher setting in the summer. Over the past year we’ve saved anywhere from $40-$120 each month on our electric bill -which is HUGE considering our home runs completely on electric. Green Homes was extremely professional and listened to our concerns. They were easy to work with and were timely with their call backs and appointments. We highly recommend!

Frequently Asked Questions — Spray Foam Insulation in Peoria

Why is spray foam insulation especially important in cold climates like Peoria?
In cold climates like Peoria, IL, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in IL typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Peoria?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Peoria, IL. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Peoria?
For cold climates like Peoria, IL, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with IL building codes can recommend the exact specification for your home.
Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic costs $2,000–$6,000. Most homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor?
Look for contractors who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
