Crawl Space & Pier-and-Beam Insulation
Cold floors, musty smells and drafts often start below the house. Spray foam seals and insulates crawl spaces and rim joists in one step.
Seal the space under your floor
Many older North Texas homes sit on pier-and-beam foundations with open, vented crawl spaces. Outside air — hot and humid in summer, cold in winter — moves right under the floor.
Closed-cell spray foam on rim joists, crawl space walls or the underside of the subfloor stops that air and helps manage moisture.

Moisture first
If there is standing water, active leaks or drainage problems, those need fixing before insulation. We will point out anything we find during the assessment.
Why closed-cell foam
Crawl spaces see moisture. Closed-cell foam resists water and acts as a vapor barrier, which is why it is our standard for below-floor work. More on closed-cell.
Crawl Space Insulation FAQ
Still have a question? Call 9402910138 or send a quick request and we will get back to you.
Will crawl space foam make my floors warmer?
Yes — sealing and insulating below the floor typically makes winter floors noticeably warmer and reduces drafts.
Do you do full crawl space encapsulation?
We focus on the insulation and air-sealing portion. If your crawl space needs drainage, a vapor liner or dehumidification, we will tell you.
How much clearance do you need?
It depends on the space. We will look during the assessment and let you know what is workable.
More ways we can help
Air-sealing insulation for walls, attics and rooflines in new and existing buildings.
Soft, expanding foam that seals and quiets homes — great for attics and interior walls.
Dense, high R-value foam that blocks moisture and adds strength to metal and exterior walls.
Seal the roof deck so your attic stays near living-space temperature through Texas summers.
