How Spray Foam Insulation Durham Works

Spray Foam Insulation Durham insulates and air seals homes and small buildings in Durham, Chapel Hill, Carrboro, Hillsborough and the rest of the Triangle. We spray open-cell and closed-cell foam, seal and encapsulate crawl spaces, tighten attics, insulate bonus rooms and kneewalls, blow in cellulose or fiberglass, and pull out old insulation that has gone wet, moldy or flat.

Every job starts with a visit. Around here the two spaces that matter most are usually the attic and the crawl space, so we look at both even if you only called about one. Up top we measure what is there, look at the ductwork and the air handler if they sit in the attic, and find the open chases, top plates, light fixtures and hatch gaps that let conditioned air escape. Underneath we check the vapor barrier on the ground, the condition of the floor insulation, standing water, wet wood, foundation vents, and pest damage. Central North Carolina summers are long and humid, and a crawl space that breathes outside air all summer can stay damp. We would rather point that out than bury it under new insulation.

Then you get a written quote. Each area is listed on its own line with the material, the thickness or depth, the R-value it should reach, and the price. Foam is not always the right answer. On a wide-open attic floor, sealing the leaks and blowing loose fill is often cheaper and works well. On a vaulted ceiling, a bonus room wall or a crawl space, foam usually earns its cost. When two approaches would both work, we show both.

How we work

Look before pricing. No phone quotes for whole houses; we measure first.
Write it down. Material, depth, target R-value and price for each area.
Seal, then insulate. Air leaks are closed before insulation goes over them.
Keep the house clean. Floors are covered, work areas are closed off and debris leaves with us.
Plan around the weather. Attic work in a Durham July is hard on people and on some materials, so we schedule with that in mind.
No surprise charges. If something changes once work starts, we agree on it in writing before going on.
