Many of Broken Arrow's older homes near downtown and the Rose District sit over crawl spaces. Those crawl spaces were built with open vents, which in a humid Oklahoma summer pull wet air under the house where it condenses on ducts, pipes and floor framing.
The results are familiar: musty smells after rain, cupping wood floors, sagging fiberglass and cold floors in winter. Damp crawl spaces also attract mice and insects.
Encapsulation fixes the cause. Vents are closed, a heavy reinforced liner covers the ground and runs up the walls, and closed-cell spray foam seals the rim joists and foundation walls, with a dehumidifier to control humidity. Every job starts with a free inspection.
Broken Arrow tip
Check that gutters and downspouts carry water well away from the foundation before encapsulating. Drainage problems need to be solved first.
Signs Your Crawl Space Needs Encapsulation
- ✓Musty smells after rain
- ✓Cold floors over the crawl space
- ✓Fallen or sagging fiberglass
- ✓Condensation on ducts and pipes
- ✓Cupped or soft wood floors
- ✓Pests under the house
What Encapsulation Includes
A full encapsulation includes sealing vents, a 10 to 20 mil liner over the ground and up the walls, taped seams, closed-cell foam on rim joists and foundation walls, and a dehumidifier or conditioned air.
For homes that do not need full encapsulation, rim joist sealing with closed-cell foam is a smaller, affordable step that stops a major air leak. Your free estimate shows both options.
