Spray Foam Insulation in Sherman, TX

Across the lake and down US-75: Great White Spray Foam covers Sherman, Denison, Pottsboro, and the Texas side of Lake Texoma.

Spray foam insulation on the Texas side of Texoma

We're based in Kingston, Oklahoma, just across the Red River, and we cross the state line all the time. Grayson County is growing fast, and new homes, shops, and barndominiums all benefit from a sealed envelope before the drywall goes up. Our rig is self-contained, so we show up ready to spray.

We cover roughly 30 miles around Sherman: Denison, Pottsboro, Whitesboro, Howe, Van Alstyne, Bells, Whitewright, Tom Bean, Gunter, and the south shore of Lake Texoma. If you're in Grayson County, you're in range.

What we foam around Sherman

Homes, shops, barns, barndominiums, and commercial buildings — open-cell or closed-cell.

New construction

Custom builds and new subdivisions around Sherman, Howe, and Van Alstyne. Open-cell in the walls and attic before drywall is the cheapest time to get the envelope right.

Shops & metal buildings

Closed-cell foam on metal panels stops condensation, adds rigidity, and makes a shop usable through a North Texas summer.

Lake Texoma homes & barndominiums

Pottsboro, Denison, and the south shore. Lake houses and barndos sealed tight so they're comfortable when you arrive and cheap to run when you're away.

Open-cell or closed-cell?

Open-cell is the budget-friendly choice for walls and attics in a house. Closed-cell is denser, blocks moisture, and stiffens metal buildings. We'll help you pick the right one for the job — read more about both or see recent projects .

Sherman spray foam questions

Yes. Sherman, Denison, Pottsboro, and the Texas side of Lake Texoma are part of our regular service area. Estimates are free, and we come to you.

For most houses, open-cell foam in the walls and a foamed attic deck give the best value and turn the attic into a conditioned space, which is where the summer savings come from. Closed-cell is the pick for metal buildings, crawl spaces, and anywhere you want a vapor barrier.

Yes. On existing homes the big wins are the attic and crawl space, where we can reach the framing without opening finished walls. On remodels and new builds we spray the open wall cavities before drywall.
