“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.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Sioux City attics swing between hot humid summers and cold windy winters along the Missouri River. We spray closed cell foam across the roof deck in older Morningside homes and newer builds toward Sergeant Bluff, sealing the attic against heat gain and winter drafts. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Closed cell foam stands up to the damp basements and hillside lots found across the Loess Hills. We use it in rim joists, crawl spaces and basement walls around Woodbury County to block moisture and add rigidity on these hillside foundations. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Open cell foam fills attic rafters and interior walls across Sioux City's mid-century ranches. It expands to seal odd framing bays in homes across Morningside and the hills above downtown, cutting sound and softening the swing between humid summers and cold winters. |
| Wall & Injection Foam Insulation | From $2/sq ft | Wall injection foam fills closed cavities in older homes above downtown Sioux City without opening the drywall. We drill small holes from outside or inside, inject foam into the cavity, and patch so the wall handles another cold Siouxland winter. |
| Crawl Space Spray Foam Insulation | From $2,500 | Some newer additions toward Sergeant Bluff sit on crawl spaces that trap humid air and damp winter cold. We seal the space and spray foam across the walls to stop the moisture that follows summer storms across Woodbury County. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim joists lose heat fast in Sioux City's full basements, especially on hillside lots in the Loess Hills. We spray closed cell foam along the band joist to block drafts and stop winter condensation before it reaches the floor joists above. |
| Garage Spray Foam Insulation | From $1,200 | Garages across Sioux City take the full swing from hot humid summers to cold windy winters. We foam the walls and ceiling, including rooms above garages in newer Sergeant Bluff subdivisions, to keep the space usable year round. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Shops and farm buildings across Woodbury and Plymouth counties sweat without closed cell foam on the walls. We spray the interior of metal buildings and barndominiums to stop condensation that forms when humid summer air meets cool metal. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Commercial projects across Siouxland face the same hot humid summers and cold windy winters as area homes. We work with contractors on new builds and retrofits across Woodbury and Plymouth counties, sizing foam systems to the building and its use. |
| Insulation Removal | From $950 | Older homes in the hills above downtown and in Morningside often carry flattened, decades-old attic insulation. We remove it along with any rodent waste or damage, clearing the attic deck so new foam bonds directly to clean wood. |
| Insulation Replacement & Re-Insulation | From $2,800 | After removal, older Sioux City attics need fresh insulation for the next heating season. We spray new closed cell or open cell foam across the roof deck, sized for attics in Morningside and the subdivisions toward Sergeant Bluff. |
| Air Sealing | From $650 | Air sealing stops the stack effect that pulls cold winter air through top plates in Sioux City homes. We seal penetrations, top plates and rim joists in homes from downtown's hillside streets to the newer subdivisions toward Sergeant Bluff. |
