“We had moisture and drafts coming into our bathroom from the attic space above, and Sioux City Spray Foam came out and sealed everything up with open cell foam. The difference is night and day, no more cold spots in winter, and the humidity issues cleared right up. They were in and out in one afternoon, left the place clean.”
Attic Spray Foam Insulation
“Our basement walls were ice cold and we could feel air leaking through the old plaster. The crew injected closed cell foam into the wall cavities and it made a huge difference. The basement is actually comfortable now in the winter. Professional crew, minimal mess.”
Wall & Injection Foam Insulation
“Got our crawl space done with closed cell spray foam and air sealing. It's an old house, so we were nervous about the work, but they knew exactly what they were doing. Energy bills dropped noticeably and the whole house feels more stable temperature-wise.”
Crawl Space Spray Foam Insulation
“The rim joists on our 1970s home were drafty and uninsulated. Sioux City Spray Foam sealed them up tight with closed cell foam and caulk. It's one of those jobs you don't see but really feel, heating costs went down and we stopped getting that cold draft along the foundation wall.”
Rim Joist & Band Joist Spray Foam
“We wanted to make our attached garage more insulated so it wouldn't affect the house temperature. They sprayed open cell foam on the walls and ceiling, took about 4 hours. Now the garage stays way warmer and we're not losing heat through that wall anymore.”
Garage Spray Foam Insulation
“Our attic had old, compacted fiberglass that wasn't doing much anymore. They removed all of it and replaced it with open cell spray foam. The crew was respectful of the house, contained the mess really well, and the attic is now properly insulated. Very satisfied with the work.”
Insulation Removal & Replacement
“We're converting a metal building into a living space and needed spray foam insulation on the inside. Sioux City Spray Foam did closed cell on the metal roof deck and walls, it was a bigger job but they stayed organized and got it done right. Building is now insulated and ready for finishing.”
Metal Building & Barndominium Spray Foam
“Old attic in our 1920s farmhouse was a nightmare, gaps everywhere, no real insulation. They sprayed closed cell foam and sealed all the air leaks. The upstairs bedrooms are finally warm, and we can actually feel the difference in our heating bills. Would definitely hire them again.”
