David and Matt did an excellent job on my building! They asked great questions to level set what I was doing with the building. They nailed the installation of the foam and the clean up was awesome as well. I also appreciated the great communication with Trish.

Assured did an assessment on my home as part of Ameren's energy efficiency program. It was set for September 16th, between ten and eleven A.M. I was already impressed because it wasn't some crazy 4-6 hour window! Josh arrived on time, was polite and professional, and was done in about ten minutes. He was knowledgeable and even pointed out some spots in my ceiling that I hadn't noticed. We shot the breeze for a moment before he left, and I could tell he was a stand up guy. Loved his American flag tattoo, too! And the lady that runs the place, Tracy I think, was very friendly when scheduling the assessment, too. She even knew my neighbors from church! I'll be going to Assured first for any work I need done on my home, and I'll be recommending my family and friends do the same.

We had them come out due to some strange humidity during the peak of the summer. Jeremy was able to quickly identify the issue, he jumped in the attic and found all the issues causing the humidity in the kitchen drawers due to poor insulation in the attic. Quote and installation went smoothly and with today being super humid and hot we didn't see the issue back. Can't recommend them enough.

They guys are great! Had an original quote done a few years ago but something came up and I wasn’t able to get the work done at that time. But when I contacted them again this year, they still had my information and were able to give me an updated quote without having to come back out. They arrived at the time they said they were going to, took a look at the attic, and got to work. My attic didn’t have any insulation and it only took them about an hour to do the whole job. They barely left any mess and what mess they did leave (little fluffs of insulation) they offered to clean with my vacuum, but I told him not to worry about it. Bonus: they changed the Lightbulb I’ve been unable to reach in the room where my attic access is that’s been out for years. Great service!

These folks quoted a job for my home (in October, 2023) that involved removing the loose fiberglass insulation from the top of the walls in our crawlspace and then replacing that gap with foam insulation. I couldn't have the work done for several months due to other work being done that had to come first in the crawlspace. When I called them to schedule, they honored their original quote price, arrived on time at our house, and cleaned up behind themselves. We're very pleased with their work and their price was reasonable.

After reaching out to several local companies Phoenix Insulation was the first and only to respond to my first contact. I had to make multiple calls/ emails to get a response from other companies. Dan came out and met me face to face, looked over my project and had a bid to me in 12 hours. They were the best price and since my project was small he was able to get it done with in 2 days of me accepting his bid. Other companies were to lazy to come out only wanted to match Phoenix's bid. Since Dan took the time to come out and was professional I chose them to do the job. They arrived on time, did a great job and didn't leave a mess behind.

In this day and age it’s difficult to find contractors that return phone calls and follow through on their promises, but that’s exactly what Phoenix Insulation did for our family! Daniel was onsite within a day or two of us reaching out to him and he thoroughly explained all our different insulation options. Their price was budget friendly and scheduling was a breeze. When Tyler came out to install you could tell he meant business and he knew what he was doing, great guy! As someone who has been in the construction business for 14 years, I would highly recommend this crew for your insulation needs!

The day the insulation was installed, I showed the foreman the damage done to my tenant's walls and ceiling. He did not pass the information a long to his supervisor. After setting up a meeting with the supervisor, I had to coordinate several other meetings in order to get the damage repaired by my contractor and his painter. There should have been some reduction in the bill considering their mistake and their insufficient follow-thru, And an additional reduction should have been made for the additional time I had to invest into correcting their mistakes.

Frequently Asked Questions — Spray Foam Insulation in Springfield

These are the questions Springfield homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 3 verified Springfield contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Springfield?▼
In cold climates like Springfield, 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 Springfield?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Springfield, 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 Springfield?▼
For cold climates like Springfield, 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 in Springfield, IL?▼
In Springfield, IL and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Springfield costs $2,000–$6,000. Most Springfield 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 in Springfield, IL?▼
When searching for a spray foam contractor in Springfield, IL, look for ones 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 Springfield 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 in Springfield 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.
