Crawl spaces
Crawl space repair
Crawl space repair controls moisture under the house: sealing the ground with a vapor barrier or full encapsulation, adding drainage and a sump where water collects, closing vents, and running a dehumidifier. A dry crawl space means warmer floors, less mold and fewer pests.
- Typical time
- One to three days.
- Repair or replace
- Drain and seal; replace rotted wood if found.
Additions, porches and some older homes in the valley sit over crawl spaces rather than full basements. Open vents let humid summer air in, where it condenses on cool surfaces.
Wet insulation falling from the joists, musty smells upstairs and cold floors in winter are common complaints.

Crawl Space Repair: common questions
Should crawl space vents be closed?
In an encapsulated crawl space, yes. Open vents bring in humid summer air that condenses and feeds mold.
Is encapsulation worth it?
It usually improves comfort, air quality and floor temperatures, and protects wood framing from moisture.
