“We had Durham Spray Foam come out to seal and insulate our attic after we noticed cold spots in our upstairs bedrooms. The crew was professional and efficient, they got the whole 1,200 sq ft attic done in just one day. Our heating bills dropped noticeably within the first month, and the difference is night and day.”
Attic Spray Foam Insulation
“Had them spray closed cell foam in our sealed roof deck and honestly, I was skeptical at first about the cost. But after one winter I'm a believer, no more ice dams, no condensation issues, and the attic stays dry year-round. Best investment we made for the house.”
Closed Cell Spray Foam Insulation
“We wanted to improve the insulation in our master bedroom walls without tearing everything apart. The injection foam retrofit they did was clean and quick, they drilled small access holes, injected the foam, and patched everything up. Can actually feel the difference when it's cold outside.”
Wall & Injection Foam Insulation
“Our crawl space was a nightmare, damp, drafty, and we could feel cold air coming up through the floors. Durham Spray Foam sealed and insulated the whole thing with open cell foam. The crew was careful with the work area and left it spotless. First floor is actually warm now.”
Crawl Space Spray Foam Insulation
“We converted part of our garage into a workshop and needed it insulated. They sprayed open cell foam on the walls and ceiling, about 400 sq ft total. The space went from freezing in winter to actually usable, and we can work out there comfortably now even in January.”
Garage Spray Foam Insulation
“Just had them finish our attic renovation with spray foam around the new skylights and along the mansard ceiling. They worked around our contractor's schedule without any issues, and the foam sealed all those tricky spots where air was leaking before. The attic feels completely different.”
Attic Spray Foam Insulation
“We're converting an old metal agricultural building into a livable space, and Durham Spray Foam insulated the entire interior with closed cell foam. The crew understood metal building challenges and did a thorough job, no gaps, and the R-value is exactly what we needed for year-round living.”
Metal Building & Barndominium Spray Foam
“We had air leaks around our rim joists that were driving our energy bills up. The team came in, sealed everything with spray foam, and the improvement was immediate. They also did some air sealing around the foundation, really professional crew that explained everything they were doing.”
