Second time using Reid's - as with the first time it was a great experience. Small job that some don't seem interested in doing. Reid's came on-site and gave a no-charge quote. Had to move the initial planned date - no problems. Showed up on-time, set up quickly, got the job done completely to my satisfaction, then cleaned up and left everything neat and ready for drywall. Will use them again.

My husband and I spoke to a lot of people before choosing Reid's Insulating to spray foam under our cottage this fall... and YES, all the positive reviews are true. We were so impressed by the high level of customer service, quality product/installation and care taken with our property. Really appreciate this great crew, and recommend them 100%.

Jay Anderson Insulation insulated my house 20 years ago and he is the best most professional in the business. If you want it done right choose Jay! Pictures for reference from the recent snow storm, zero heat loss as you can see my roof in direct sunlight and neighbors in shade. Ours still has the majority of the snow compared to others on our street

I hired J. Anderson to remove the insulation in my attic for a home renovation, and they exceeded all expectations! Their team was professional, timely, and highly knowledgeable. In contrast to expensive competitors who seeked to sell overpriced + add-ons, J. Anderson provided quality service at a reasonable cost. They didn't just finish the job—they went above and beyond, making great recommendations for air sealing, new exhaust vents, and addressing out-of-code matters to uPDATE my renovation to-do-list. Instead of ramming information down my throat, they politely asked if I'd like more information, which was nice. Uncertain about the negative reviews further down, but I think those cats are lost and on the incorrect business review site. I will definitely be using them in the future! Highly recommend!

Couldn't be happier! Owner is very knowledgeable and explained everything in terms I understood. After a month of hot temperatures I have noticed a huge difference in the amount of time my AC runs. I used to keep the thermostat at 68 degrees in the summer months, but since the new insulation I can keep it at 76 degrees and still be very comfortable. Saving energy and saving dollars! Highly recommend this company!

Referred by a friend for insulation in our attic. We worked with Bob the whole time and he always got back to us when we had questions. Bob was knowledgeable and took the time to explain to us what we really needed in our attic and didnt just try to get as much money out of us as possible for stuff we didn't really need. We definitely appreciated his honesty and down to earth mentality, he talked to us like he was talking to a friend he'd known for years. We had some delays on our end as well as the holiday and vacations on their end, but they showed up on time on the scheduled day (a little early even). The two gentlemen were very nice and tried to keep the mess down as much as possible and they did warn me of a few areas they were unable to completely pick up. We've already noticed the change in the amount of time our ac units run and can't wait to see the difference on our utility bills for the rest of the summer and this winter. They did a great job and I'd recommend them as well as use them again!

Frequently Asked Questions — Spray Foam Insulation in Belleville

How much can spray foam insulation save on heating and cooling bills in Belleville?
Homeowners in mixed climates like Belleville, IL typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Belleville?
For most homes in Belleville, IL, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
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.
