We had a great experience with Accurate-Airtight, from start to finish. We were amazed that in this busy insulation season Steve was able to come do the blower test, explain his recommendation in detail, and get us an estimate. We were also amazed that the crew could fit us in, in November. The crew: Brandon, Chris, Deylan, Mason, Wallace, Joe, and Steve were wonderful: friendly, efficient, careful, and did great work. Our old 1899 house is now performing at much more energy efficient levels. We highly recommend this company!

The warmer summer nights of climate change were pushing my 1909 arts and crafts bungalow to the point of uninhabitability, particularly on the second floor, by making it impossible to air out the house overnight. Cue A-A Exteriors coming to the rescue. Hunter P. worked with associates to design a comprehensive tune up for my home, top to bottom, with insulation, air sealing, and proper ventilation. Derek and James led the plan’s execution with a team of installers who worked tirelessly and with collegial good humor at tasks that were physically challenging and mentally tedious under varying conditions of comfort, or lack thereof, day after day. I never heard a cross word spoken or a voice raised over the course of more than two weeks of work. That’s leadership! Such an old house inevitably yields surprises, but the team problem-solved every challenge and completed every goal. Cory painstakingly documented my home’s condition pre- and post-construction, but I didn’t need data to know the company’s work has paid off. My home has been transformed, and not a day too soon given this summer’s hot nights and hotter days. Now I can enjoy the charm of an older home with the comfort of a new one. Thank you, A-A Exteriors!

Had excellent and responsive planning experiences with Torrance on a tricky insulation condition (uninsulated 2x4 rafter ceiling). Hunter was timely and professional running the Energy Audit and promptly followed up to answer questions I had. The insulation crews were efficient and professional. I would work with them again without hesitation.

They did a great job. They arrived on time, were neat and precise and cleaned up after the job. The post frame building has a wainscoting all around the building and I was concerned about sealing the bottom of the walls to the floor. The product did a great job sealing and keeping out the cold in the winter and cool in the summer.

These guys did a fantastic job! They came when they said they would. I wanted high density form which made it a little trickier and they completed it very well and they cleaned up everything beautifully!

Megan Williams★★★★★a year ago

The quality of their work was outstanding, securing their position as my exclusive choice for spray foam services in the future. A play was how easy their website was to access when I needed more information. I wholeheartedly recommend them to anyone in need of air sealing assistance.

Kind of small facilities for a big 🚚 but nice people let me sleep on site when I was there had no shift time to drive to a truck stop

This company takes every shortcut possible and has no integrity in their work. We are in a new build and there are visible seams in our ceilings, many cracks, and pieces that are separating. The builder got Alpine to come back to fix their work but that is a disaster, too. The crew beat up the exterior of our house when they brought in their scaffolding, got mud all over our finished doors and scoffed when we told them we needed to be able to sleep in our bed and access our second floor every night after they finished working. Their scheduling person sent the same person out twice to assess the situation because they didn't think the right person came the first time, but only realized it when I contacted them to question why the work hadn't been scheduled. Do not work with them if you want at least a halfway decent drywall job done.

Frequently Asked Questions — Spray Foam Insulation in Madison

These are the questions Madison 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 Madison contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Madison?
In cold climates like Madison, WI, 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 WI 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 Madison?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Madison, WI. 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 Madison?
For cold climates like Madison, WI, 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 WI 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 Madison, WI?
In Madison, WI 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 Madison costs $2,000–$6,000. Most Madison 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 Madison, WI?
When searching for a spray foam contractor in Madison, WI, 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 Madison 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 Madison 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.
