Environmental Testing in Oregon
Mold Test Kits, Asbestos Test Kits & Soot Test Kit

Western Oregon's heavy annual rainfall — Portland averages over 37 inches per year — makes mold the most common indoor environmental concern for homeowners. The region's mild, wet winters and damp springs create near-constant humidity that drives mold growth in attics, crawl spaces, basements, and wall assemblies. Any home with inadequate vapor barriers, poor ventilation, or any history of roof leaks or moisture intrusion is at significant risk.

Portland's older housing stock — the city has significant pre-1980 residential construction — contains asbestos in floor tiles, insulation, ceiling tiles, pipe wrap, and exterior siding. Asbestos testing before any renovation of a Portland-area or other older Oregon home is strongly recommended. Other Oregon cities with significant older housing include Salem, Eugene, and Astoria.

Eastern Oregon increasingly faces wildfire risk, and even western Oregon communities have been exposed to significant wildfire smoke during recent fire seasons. When wildfires burn near residential areas, soot and fine particulate matter penetrate homes and deposit on surfaces throughout the house.

Portland Mold and Asbestos Risk

Portland homeowners face a dual risk from Oregon's two most significant indoor hazards: mold from the region's wet climate and asbestos from the city's significant stock of pre-1980 construction. Both should be evaluated before any renovation project.
