Gresham sits at the eastern edge of the Portland metro, with Johnson Creek winding through town and neighborhoods climbing the slopes of Gresham Butte and the area’s other buttes. Homes on the buttes and hillsides take on a lot of runoff, while homes near Johnson Creek and in the flatter parts of town sit on heavy clay soil 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 Gresham 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 Gresham 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.
