Different parts of town, different water
Homes on the lower ground near the rivers can see water rise through saturated soil in long wet spells. Homes on the hills more often get water seeping in from the uphill side. And Washougal's rapid growth — the population roughly doubled between 2000 and 2020 — means many newer lots whose drainage is still settling in.
The drain system
- Locate the entry points and low areas
- Trench and lay perforated drain pipe
- Slope it to a sump or gravity outlet
- Replace the vapor barrier over the top
Wet insulation and cold floors
When a crawl space holds water, insulation above it tends to absorb moisture and sag — and in Washougal's colder east-wind spells, that shows up as cold floors. After drainage, we'll check the insulation and include replacement in the estimate if it's needed. See insulation in Washougal.
Plan the discharge
Water pumped or drained out needs to go somewhere safe, away from your foundation and your neighbor's. We plan that route with you.
What shapes the scope in Washougal

- Insulation and barrier damaged by past water

Pairing drainage with comfort
Many Washougal homeowners notice a damp crawl space and cold floors at the same time. Dealing with the water first means the insulation you put back in can actually stay dry and do its job. It's worth planning both together, even if you do them in stages.
Questions from Washougal homeowners
Do newer Washougal homes need drainage?
Some do, especially on lots where grading sends water toward the house.
Will drainage fix my cold floors?
Drying out the crawl space is the first step. From there, new insulation keeps your floors warmer — and we handle both.
