Why spray foam
Built to save.
Traditional insulation slows heat. Spray foam stops air. That single difference is why foam-insulated homes feel warmer, quieter and cost less to heat, even in January.
Energy savings
Seal the leaks that drive up heating bills. Most people notice the difference on their first winter gas bill.
Total air sealing
Foam expands into every crack and seam, stopping drafts, cold spots and the heat loss that causes ice dams.
Moisture control
Closed-cell foam resists water and blocks vapor, protecting framing from condensation, mold and rot.
Stronger walls
Closed-cell foam bonds to framing and sheathing, adding rigidity and reducing wind noise.
Open cell vs closed cell?
Open cell for interior walls, attics and sound. Closed cell for pole buildings, rim joists, basements and moisture. We spec the right foam for every surface.
Before & after
See the difference.
Drag the handle to compare. Bare framing on one side, finished foam on the other.
BeforeAfterAttic
Bare roof deck to a fully sealed, conditioned attic with open-cell spray foam.
Who we work with
One crew. Every scale.
No job too small or too big. One bedroom or a 10,000 sq ft shop, we do it the same way.

5.0 average rating
“Our upstairs bedrooms were freezing every winter. After Comfort Built sprayed the attic, the whole house holds heat and our gas bill dropped noticeably. Crew was on time and spotless.”
“We had condensation dripping in our pole shed every spring. Closed-cell foam fixed it completely, and now the shop stays warm with a fraction of the heat.”
“As a builder I need an insulation sub who shows up when they say and passes inspection the first time. That's exactly what we get every job.”
