I have had insulation done 3 times in different parts of my home. The 1st time was done in all the walls of the house. That winter i noticed my gas bill went down from previous years. The 2nd time was my family room ceiling. The 3rd time was Oct. 14. 2025. I had the garage done. It keeps the garage warmer by 20 to 30° I read on line. So far it has stopped the mice from moving in since I had this done. I had a serious issue with mice for 2 years. Thank you for being so thorough and extremely helpful. Your employees went above and beyond each time to help me out. All your employees were great, friendly, professional and did an excellent job doing the work and clean up. I definitely recommend 👌 them

Nothing but good things to say! For starters, their quote process was very quick, easy and much more realistic than some other large companies!! Scheduling was easy! The actual install went perfectly and the crew cleaned up after themselves leaving no mess. I would not hesitate to recommend them to friends or family!

R S★★★★★3 weeks ago

I've had Ryen and his team out to upgrade my bathroom fan and properly vent it though the roof, resolve some mold in the attic, and do an insulation and ventilation upgrade in the attic and they've done a great job every time. They we're responsive and quick to schedule. When giving a time when they'd show up I was given a specific time instead of a half-day window and when they finished for the day they always cleaned up before leaving. I didn't get competing quotes for the smaller jobs but the price for the larger project was slightly higher than other quotes with the caveat that they were not one to one quotes. One of the differences being that Ryen did some actual construction work while the others wanted to just use foam blocks and the more permanent solution and quality was worth the cost. I'll plan to use them again when I have more insulation or ventilation work done in the future.

Leonard DeMontigny★★★★★a year ago

Ryen and his crew completed the job in a timely manner. Both him, and his crew were very professional and courteous. They cleaned up after themselves every time they were finished for the day. The quality of their work was excellent. I would highly recommend Accurate Insulation Solutions LLC to all people looking for quality workmanship at a fair price. Thank you.

Mary Sucich★★★★★5 months ago

Ryen and Crew were exceptional. They were very very professional and got the job done in time frame they stated. The cleaned up after the work was done and we could not have been happier. I would recommend them to anyone and you would not be disappointed.

Great crew, great company. They completed a 2,000sqft aircraft hangar with closed cell foam. They protected the floor, doors, and equipment from overspray. It took a crew of two, 4 days to complete. They paid special attention to detail and made sure there was even coverage. I would recommend them to anyone needing foam insulation and wouldn't hesitate to have them on future projects.

Katie Cuda★★★★★a year ago

Scott and Robbie did great work on our closed cell foam project. They completed a fairly large res project in one day and left the site clean and ready for inspection/drywall. Dave was our sales rep and informed us of rebates and answered all of my questions about the process whenever I called. Great company and competitively priced.

Robert McAllister★★★★★a year ago

My hat's off to this crew! Scott, Robby, Mason, and Anthony performed an upgrade to my insulation situation in record time. In just under 5 hours, they foamed my basement and attic space, including removal and clean up. The crawl space was tight and problematic but they got it done. My wife said it's cozy already! I'll be sure to be saving some money too on my utilities.

Wisconsin Insulation Services was very easy to work with. I was remodeling my entire basement( about 1600 sq ft) and had a lot of questions. I spoke with Keith who was very responsive, and answered all my questions. He made it very easy, working from my design plans for a quote. I feel their prices were fair and Keith helped me decide between different levels of the closed cell insulation. When my project took a little bit longer before I was ready for the insulation they were very accommodating and rearranged the schedule to fit me in exactly when I needed their services. On the day the installer came he was very respectful, answered any questions and I felt he did an excellent job. I would feel very comfortable recommending them and using their services again.

Kyle Turk★★★★★a year ago

Had the basement rim joist air sealed/spray foam insulation done at my home yesterday and the technician Quintin did a fantastic job. Working with Matt was great and I would definitely recommend this company.

Karen Wendling★★★★★6 months ago

We needed our attic insulation replaced due to rodents. Contacted Matt and knew i made the correct call right away. Justin came out to inspect the attic and determine several problems. They were able to schedule us within two weeks. The very professional crew came out and kept everything as clean as when they got here. Found and fixed a few problems we didn't know about and finished the whole job in less than a day. Attic looks like new, all the fans are vented properly and things are sealed up as they should be now. Price was in line with other estimates but I know these guys do more than other companies do for the price. Would definitely recommend this company if you need new insulation or a complete replacement like we had done. Communication was great also.

Charles Tukiendorf★★★★★7 months ago

Matt and his team were a pleasure to work with, all were very professional. We had vermiculite in our attic, and they were extremely professional on how to remove it without it getting in the house at all. The vermiculite did not once enter the house once. If I need to have more insulation work done, I will certainly work with Matt and his team again.

Green Homeowners United inc helped us upgrade our home to 200 amp service. They were wonderful to work with throughout out the entire project. Their electrical team arrived at our home at the scheduled time and worked quickly and efficiently. The project was completed using only high quality materials. I would definitely hire this company in the future for home improvement projects.

We first heard these guys on NPR and decided to follow up. It was really a simple process, and eye opening to see how much cold air was coming into the house. We noticed a difference immediately, the basement feels warmer, quieter and looks way cleaner than just the old basement paint. These guys get the jobber done. 10/10.

Ron Mouradian★★★★★a year ago

We had our attic insulated by green homeowners united and were very happy about the job. Kevin's crew did a fantastic job. They took every precaution to make sure they did not make a mess. They made sure everything was clean when they were done. I highly recommend them.

WELL worth the read! Customer service ? This company is right on point! From Zack and Amy to the rest of their team, wow! Until I found these two companies, I had an awful and long time getting one to return my calls or come out for an estimate. I saw an ad on TV for Healthy Home Insulation, left a message on a Sunday, they came out the next day! Before Erik left he gave me an estimate for attic and basement (Healthy Homes) as well the walls from (Cozy Walls Insulation.) They were out here the following week to complete the job! I have HORRIBLE allergies that can cause my eyes to swell shut to causing vertigo. I was concerned that the smell of foam spray would be an issue. Amy, Cozy Walls said they would come out try a wall see how it went. If it was ok, complete the job, if not, we would figure something out. To me this is a company that truly cares about their customers! BOTH companies have gone above and beyond from start to finish. I would recommend them to anyone!

I can’t say enough good things about this company. After one initial hiccup, which was resolved with complete courteousness to me as a customer, this company impressed me from start to finish. The pricing was fair. The ownership is attentive to its customers. The employees were efficient, effective, and all-around good people. The job foreman was informative and attentive to detail, including the cleanup when they were done. If you’re questioning whether or not to use this company, I can assure you they are the right ones to use. A big thank you to the USA insulation team for doing a great job!

Mateusz Laskowski★★★★★2 years ago

I had USA insulation do blow-in insulation in my garage attic space. Not only was everything on time, but it was done correctly and with no mess left behind. Also, Alex the owner is easy to work with and is an honest and stand up individual. You will get treated with integrity and respect, get top of the line products and service, and a very well insulated space when you sign on the dotted line with USA insulation. I'd give more stars if I could.

Karen Roschyk★★★★★3 years ago

We called USA Insulation after looking around for a contractor to insulate our 40 year old house. They were polite and professional from the first interaction to the final cleanup after installation. The sales rep came out to our house, did a visual inspection, and drilled into a selected area of our house. As we have come to expect, the comment was along the lines of "I've never seen that before". Yes, we know previous owners made poor choices. Can you correct that, and how much will it be to do so? We opted for the whole house package. While our attic is well insulated, there were a few areas that needed some improvement and the team blew in additional insulation. The real issue was the outer walls of our house, which on insulation install day, we were informed that some areas (namely, our north wall), appeared to have zero insulation. This did not surprise us, rather continued to disappoint, as so much about our house does. The team was careful with our siding, which I appreciate. While our goal is to replace the siding, as it is original to the house, that is slated for next year. They carefully removed pieces to enable the insulation install, and just as carefully replaced the siding sections at the end of the day. The team assured us the siding would be just fine this winter. We haven't gotten our next WE Energies bill just yet, but I am expecting it to drop, as the house has been much more comfortable in the three weeks since installation, and much quieter. We are sleeping more soundly, and not as bothered by the constant drone of riding lawnmowers. The real test will come this winter, when we will see if the entire western half of our living room floor is freezing cold, or if it remains reasonably comfortable.

Frequently Asked Questions — Spray Foam Insulation in Waukesha

These are the questions Waukesha 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 11 verified Waukesha contractors above for exact quotes.

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