“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.”

| Service | Starting from | Description |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a 150°F Durham attic into conditioned space. The air handler and ductwork that so many Triangle homes run overhead end up inside the envelope. Every estimate lists the R-value target; the thickness per pass; the board footage. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Two-pound closed-cell foam delivers R-6.5 per inch with its own vapor retarder and real structural stiffening. The right product for crawl space walls; daylight basements; metal buildings and anywhere Carolina humidity and red-clay moisture push hardest. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Half-pound open-cell foam air-seals attics and walls at a friendlier price per board foot. Sound dampening between rooms comes with it. We spell out where it belongs, and where a Triangle crawl space or basement wall calls for closed cell instead. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for Durham's mill houses; 1920s bungalows and 1950s-60s brick-veneer ranches with empty cavities. Ports go under a siding course or along a mortar joint and are patched to match. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on crawl space walls and rims holds back humid air over Durham red clay. Moisture is fixed first and we leave the inspection strip your termite bond calls for. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim joists over daylight basements and crawl spaces leak conditioned air at every framing gap. So do the cantilevered floors of rooms over garages. Closed cell seals them for good, the small-ticket job with the fastest comfort payback in a Durham house. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms are foam-sealed against radiant afternoon heat. Workshop conversions are handled the same way. The difference between a storage oven and usable space. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a Carolina metal building from sweating. Shops; barndominiums; pole barns and old tobacco-country ag buildings sealed against condensation from Chatham and Person County acreage to Mebane warehouses. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; offices; churches; soundstages and production builders served on schedule. Code-compliant assemblies come with documentation your local inspector will actually accept. Phased work keeps your operation running from Research Triangle Park to Mebane. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Squirrel and raccoon contamination comes out with it. We also cut out failed spray foam; the job most installers will not touch. Vermiculite gets flagged for testing; never disturbed. |
| Insulation Replacement & Re-Insulation | From $2,800 | The full reset: old material removed; gaps air-sealed; new foam installed to current code R-values. The right call when insulation is flattened; rodent-fouled; soaked by a roof leak after tree or storm damage or simply twenty years past its job. |
| Air Sealing | From $650 | Top plates; can lights; chases; knee walls and attic hatches leak more cooled air than most walls. We seal the leaks before insulating, the step that makes every R-value actually perform and the cheapest comfort fix in a Durham house. |
