A lot of Claremore homes, especially older houses near downtown and many rural homes around Rogers County, sit over a crawl space. Those crawl spaces were built with open vents to let air flow underneath. The problem is that in a humid Oklahoma summer, the outside air coming through those vents is often wetter than the crawl space itself, and the moisture condenses on ducts, pipes and floor framing.
That shows up inside the house as musty smells, higher humidity, cupping wood floors and cold floors in winter. Under the house it shows up as sagging fiberglass, rusty ductwork, mold on joists, and mice and insects that love the damp, sheltered space.
Encapsulation fixes the cause. Vents are closed, a heavy reinforced liner covers the ground and runs up the walls, seams are taped, and closed-cell spray foam seals the rim joists and foundation walls. We start with a free inspection that checks drainage, humidity and your current setup, then explain exactly what your crawl space needs.
Claremore tip
Check where your gutters drain before encapsulating. A downspout dumping next to the foundation can push water into the crawl space faster than any liner can handle.
Signs Your Crawl Space Needs Encapsulation
- ✓Musty smells that get worse after rain
- ✓Cold floors in winter over the crawl space
- ✓Fiberglass batts sagging or lying on the ground
- ✓Condensation or rust on ducts and pipes
- ✓Standing water or damp soil under the house
- ✓Mice, insects or snakes living in the crawl space
What Encapsulation Includes
A full encapsulation typically includes closing or sealing the vents, a 10 to 20 mil reinforced liner over the ground and up the walls, taped seams, closed-cell spray foam on the rim joists and foundation walls, and a way to control humidity. That is usually a crawl space dehumidifier, and sometimes a small supply of conditioned air from the HVAC system.
If water collects in the crawl space after storms, drainage comes first, which can mean regrading, fixing gutters or adding a sump. For homes that do not need a full encapsulation, sealing rim joists and insulating the walls or floor with closed-cell foam can be a good intermediate step. Your free estimate lays out both options.
