Mold in Vancouver is a moisture problem, not a mystery
Our rain pattern, our soil, and the way Pacific Northwest houses are built all push water toward the same few places. Knowing which one is half the fix.
Eight wet months
Vancouver averages about 42 inches of rain across roughly 160 days a year, and almost all of it lands between October and May. Outdoor humidity sits near 84 percent through December. Nothing under your house dries out for most of the year.
Crawl spaces, not basements
Most Clark County homes sit on a vented crawl space over bare or barely covered soil. Those vents pull damp winter air straight under the floor, where it condenses on cold joists and ductwork. It is the single most common mold location we hear about.
Mild means never dry
Our winters rarely freeze hard and our summers are short. Mold needs about 60 percent surface humidity and temperatures it already gets here year-round, so growth that starts in November is still going in April.
Independent & verified
Washington issues no mold-specific license, so anyone can print a card. We match you with registered, insured Clark County contractors and tell you exactly how to check them yourself at L&I before you sign anything.

Estimates use 2026 Southwest Washington labor and disposal costs: an $8–75/sq ft base depending on how porous the affected materials are, with surcharges for black or toxic-appearing mold, active water intrusion, and crawl space vapor barrier or encapsulation work. A $500 minimum applies. Crawl space access — how tall the space is, how far the hatch is from the problem — moves Clark County pricing more than almost anything else, so get a free on-site quote to confirm.
