How We Approach Wet Basements and Crawl Spaces
Vancouver's cool, wet winters push moisture into basements and crawl spaces. Fixing it for good means finding where the water comes from first, and then matching the fix to the cause.
We find the source first
Water can come from roofs and grading, from the ground, through cracks or from a leak. Each needs a different fix, so we work out which it is before recommending anything.
Basements and crawl spaces
We handle wet basements and damp crawl spaces, including drainage, sealing, sump pumps and moisture control, so one visit can look at the whole house.
Drainage that goes somewhere
Collected water has to be sent away from the foundation and off neighboring property. We plan the discharge as part of the work, not afterward.
Honest about what each fix does
A liner on its own does not stop wall seepage, and a pump alone does not stop water coming in. We explain what each option does and does not solve.
Structural issues are flagged
Horizontal cracks, stair-step cracks and bowing walls can point to movement. We tell you when something needs a structural engineer.
Options explained before work begins
We explain what we found and the choices available, so you can decide with the facts in front of you.

Our Story
Waterproofing Vancouver Homes with Hands-On Local Knowledge
Nathan Lyon started Vancouver Waterproofing LLC to give Clark County homeowners straightforward solutions for the moisture problems that come with mild wet winters and warm dry summers. Working from the ground up in neighborhoods like Downtown Vancouver and Uptown Village, he built the company around direct owner involvement and a clear understanding of how older housing stock near Fort Vancouver National Historic Site and the Columbia River responds to seasonal rain.
The crew focuses on crawl space waterproofing that fits the terrain and soil conditions found in Hazel Dell, Orchards, and Felida, where drainage patterns and foundation types differ from newer builds farther out. Clients in Camas and Washougal also call on the same methods when Portland-area weather patterns push extra water across the river. Every job starts with an on-site walk-through so the team can match the fix to the actual house instead of a one-size approach.
- Owner Nathan Lyon handles project oversight on every Waterproofing Vancouver job instead of handing off to crews who do not know the local housing stock
- Crawl space waterproofing tailored to the wet-winter drainage issues common in Clark County neighborhoods like Orchards and Hazel Dell
- Service reaches nearby cities including Portland, Camas, and Washougal using the same methods proven on Vancouver foundations
- Convenient access at 4001 Main St, Vancouver, WA 98663 with weekday and Saturday hours that fit real homeowner schedules
What to expect, start to finish
Inspection
We look at the basement or crawl space, the foundation, the gutters and the grade outside, and when and where water appears.
Finding the source
We work out whether the moisture is surface runoff, groundwater, seepage through the walls, humidity from the soil or a leak.
Explaining the options
We explain what we found and the options that fit, including what each one does and does not solve.
Installation and testing
We carry out the agreed drainage, sealing or pump work, test it where it applies and clean up.
