West Linn sits on steep hills above the Willamette and Tualatin rivers, across from Oregon City. Hillside lots here send runoff downhill toward homes, and properties closer to the rivers deal with a high water table during our wet winters. Under a house, that water turns into puddles, constant humidity, mold, wood rot and pests, and the moisture doesn’t stay in the crawl space. It rises into your home and affects the air you breathe.
We start by finding out how the water is getting in. Depending on what we find, waterproofing your West Linn 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 West Linn 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.
