Bixby sits on both sides of the Arkansas River, and homes in low-lying areas near the river and along creeks deal with more humidity and ground moisture than homes on higher ground. Older homes and some custom homes built over crawl spaces feel it most.
Vented crawl spaces pull humid summer air under the house, where it condenses on ducts, pipes and floor framing. The results include musty smells, cupping wood floors, sagging insulation and pests.
Encapsulation fixes the cause: vents are sealed, a heavy reinforced liner covers the ground and walls, closed-cell foam seals the rim joists and foundation walls, and a dehumidifier controls humidity. Every job starts with a free inspection.
Bixby tip
If your lot is low or near the river, check drainage and gutters first. Water needs to move away from the foundation before encapsulation.
Signs Your Crawl Space Needs Encapsulation
- ✓Musty smells after rain
- ✓Cupped or soft wood floors
- ✓Sagging or fallen insulation
- ✓Sweating ducts and pipes
- ✓Standing water or damp soil
- ✓Pests under the house
Is a Vapor Barrier Enough?
A thin plastic sheet on the ground, sometimes called a vapor barrier, slows moisture but leaves vents open and seams loose. Full encapsulation uses a 10 to 20 mil reinforced liner up the walls with taped seams and sealed vents.
Closed-cell foam on the rim joists and walls adds insulation and acts as a vapor retarder at about 1.5 inches. A dehumidifier keeps humidity in a healthy range, which is especially important near the river.
