About Crawlspaces in Tigard, OR
Tigard's housing stock spans 1960s ranch and split-level homes near downtown and Metzger, 1980s through 2000s subdivisions on Bull Mountain and around Summerfield, and newer hillside builds. The shared issue across all three eras is moisture: Fanno Creek runs through the city and creates a floodplain along the eastern edge of Tigard, contributing to a high local water table in low-lying neighborhoods even during dry years.
The most common Tigard crawl space scope is a combined drainage plus encapsulation project. Homes near Fanno Creek and the King City-adjacent flat areas often see seasonal water at the foundation, requiring an interior perimeter drain and sump pump before vapor barrier work can be effective. Bull Mountain and other hillside lots see groundwater migration from uphill, sometimes addressed with a curtain drain installed uphill from the foundation.
1980s and 1990s Tigard tract homes typically have the same degraded R-19 fiberglass batt and 4-mil to 6-mil vapor barrier issues as the rest of the Westside, and many have failed perimeter drainage systems that were original to the build but are now clogged or collapsed. A licensed CCB contractor inspection identifies whether the existing drain can be cleared or needs full replacement.
Tigard sits in the Westside service zone. Contractors are Oregon CCB-licensed. Verify any contractor at oregon.gov/ccb before signing a contract.

- Oregon Residential Specialty Code R408 permits both vented and sealed (encapsulated) crawlspaces. Vented crawlspaces require minimum net-free-vent area and a Class I vapor retarder over the soil. Sealed crawlspaces require a sealed vapor retarder and one of three conditioning methods: mechanical exhaust, supply air from the conditioned space, or a dehumidifier. In Portland-metro climates, sealed crawlspaces typically outperform vented ones for moisture control.
- In Tigard, OR, the most common starting point is degraded original materials in homes built between 1970 and 2000: torn vapor barriers, sagging R-19 fiberglass batt, and rim joist condensation.
