Portland’s long rainy season is hard on crawl spaces. Older homes across the city, from inner neighborhoods built in the early 1900s to mid-century houses on the east side, often have vented crawl spaces with little or no drainage. After weeks of steady rain, water collects under the house, causing puddles, high humidity, mold, wood rot and a musty smell that reaches the rest of the home.
We start by finding out how the water is getting in. Depending on what we find, waterproofing your crawl space may involve a perimeter drainage system, a sump pump, sealing foundation walls and vents, a heavy-duty vapor barrier or a complete encapsulation. We’ll lay out the options in plain language so you can choose what makes sense for your home and budget.
Pacific Waterproofing is a family-owned company that has served Portland and the rest of the Portland-Vancouver area since 2015. We’re not here to upsell you. We’ll show you what we find, explain it in plain terms and give you a fair price.
