PEAK did a fantastic job from start to finish, they made the quoting process easy and walked me through each step. During installation, Wayne showed up bright and early, ready to work, his son Matt just seconds behind him, also eager to get started. They made quick work and left a ventilation unit behind to help air out the basement. Wayne took extra care to make sure I understood what needed to happen before my dogs and young children could enter the house, truely caring about the customer beyond just the job. After the work was done, we came home to a clean jobsite. We were also happy with the communication during the process. PEAK was easily accessible, and addressed numerous odd questions with a very nice response time. Through and through the process was easy, the work was great, the service was great, and it's always nice to see the father/son team kicking butt. Could not be happier. Thanks PEAK!

Matt and his crew were extremely helpful, courteous, and professional. We got our whole attic vapors sealed, updated to R50, and also got a huge part of our house that wraps around. They showed up right when Matt said they would ready to go, they laid down plenty of protective material to prevent the carpet from getting dirty, and then cleaned up better than I did before they came. The work was done so well, we were able to notice the difference immediately. Matt had all the rebate paperwork ready for me so all I had to do was fill on my address, sign it, and throw in a envelope to be mailed out. Great job, would highly recommend for any insulation job.

Jonny Yucuis★★★★★4 years ago

We used Insul-Seal for helping to improve insulation in our 1940s house and it has provided a vast improvement for the comfort in our house. Matt and his team were very responsive, took time to answer questions, helped to fill out rebate paperwork, and more. I'd highly recommend using them for insulation work.

Very happy with the attic insulation install. Very thorough and professional. Great price compared to other companies we got quotes from. Would totally recommend them.

Frequently Asked Questions — Spray Foam Insulation in Rochester

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.
