Review Us

						Fox Cities RetroFoam of Wausau, sent two workman, Zach and Alex, to install foam insulation in our walls. We own an old manufactured home which needed new insulation badly. The two man crew showed up on time (9am), introduced themselves and promptly went to work. Finishing the South side and east end, they reported in to us and left for the day. They returned the next day promptly at 9am and again went right to work. Finishing up the North side and West end they cleaned up any mess they might have made. Couldn't even tell they had been here. Very happy with the crew and their work. Was it worth the cost? Too early to tell. We heat with propane. It's refreshed on a keep fill basis and we have a couple of weeks to go before the refill. I'll repost here the results. But, so far the house seems less drafty. We're happy.

						Zach and Alex did a great job. 5 stars from start to finish. They take pride in their work and it shows. I am happy to recommend Fox Cities Retrofoam. They successfully made a 1920's house energy efficient and much less drafty, yet you cannot tell that they were here. Great company and great technicians! 5 stars Dan

						I was impressed that the walls did not vibrate as much as I had thought and been explained to when the foam cores were drilled in. Just make sure to have the outside walls removed of pictures and any hangings on the windows. No foam entered in through our outlets. Didn't have the brick done. The team overall did a good job in minding the property and cleaning up. When they had a leak in the foam gun, they were quick to let us know and come back the next day. With a 1991 house, the siding is old; one piece did break and they came right out the next day to replace it quite close to the aged color. Elijah, Abigail, Maylou, and Micah and crew worked very well together in communicating with me to get the job done! I look forward to reduced heating costs over the long run.

						Had retrofoam being done in my 1880 home with attic insulation happening next week. Every estimate was broken down neatly with various options talked about. Pricing was clear and, while certainly not price-first, came in around the expected project cost for a far better result than I expected. Crew was respectful and kind, even when my ancient wood paneling had a blowout, causing a large mess in my living room. They cleaned any foam entrance into the home and fixed the wood board. It looks brand new and my entire home is already more comfortable and quieter. Definitely recommend Fox Cities Retrofoam for older homes with little to no insulation!! Very excited to have the attic done next week!

						We had whole home insulation done and immediately saw our electric bill drop. We are easily saving over $130 a month on our energy bill. The guys who came to do the work were friendly and respectful. They did a great job and we could not be happier. It also keeps our water pipes warmer so it takes much less time to get hot water to the shower on the second floor. We love it.

						The guys from the company were really nice and they explained everything they were doing and what to expect, with taking the siding off and how they put the foam in and putting the siding back on. They made sure we did a walk around to see if all was okay. A very good group to work with.
