These guys did a great job on my house, and very professional about keeping things clean. We did spray foam and blown in and their prices were extremely competitive for the high quality of service. This is a family owned/run business and it certainly shows.

Dale and team were great to work with! They did spray foam on our 2nd floor exposed floor and vertical walls, 2nd floor attic insulation and soffit to peak air flow improvements, and insulated a section of inaccessible flat roof/ceiling above a room attached to our garage. They were on time, efficient, clean, and communicated with us every step of the way. We've worked with a few different contractors while improving our home and this was by far the smoothest. Thank you Amundson Insulation!

Outstanding Service and Top-Quality Work! I couldn’t be happier with the results from Erikson Spray Foam Installation. From the first consultation to the final cleanup, their team was professional, punctual, and incredibly knowledgeable. They took the time to explain the process, answer all my questions, and made sure everything was done to the highest standard. The insulation has made a noticeable difference in comfort and energy efficiency in my home. If you’re looking for reliable, high-quality spray foam insulation, Erikson is the way to go. Highly recommended!

Attached are some before and after photos. Overall, I'd say it was a positive experience. You can see how well everything is sealed in the photos. Our situation leading up to this project was mildly stressful as we had mold on our rim joist from cold condensation over the winter, so I wanted so get the rim joist spray foam insulated in order to create an air barrier and help insulate the area. USA Insulation had a great sales team and front office that was great at answering any questions we had. One item I stressed was getting the sill plate sealed, I was told it would be and it was mentioned in the quote. When the spray foam team came out, I noticed they were not spraying the sill plate. I checked with the crew leader and we sorted it out by checking the invoiced paperwork. The team was quick to fix the mistake and apologized for missing that piece. I walked around with the team to make sure we got the proper amount of insulation installed and that all gaps were filled. After everything settled and I doubled checked the work, there are a few spots I want to touch up, but overall the work looks really good and I'm happy that we got this project finished and over with. I would recommend highly USA Insulation for a rim joist spray foam job.

The team of Brian,Kevin, Keith and Jeff did a top notch job. Brian found two hidden dryer vents that were open to the outside. It was an expressway for mice to enter the home. They sealed them. I am extremely grateful for that. All in all I'm very happy with the insulation removal and replacement. I highly recommend USA I insulation.

Frequently Asked Questions — Spray Foam Insulation in Kewaskum

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

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