Your dry foundation starts with a proper inspection and proven solutions sized to local soil and hydrostatic pressure.

Tailored Solution Plan
West Linn's clay soils and 40+ inches annual rainfall require specific drainage and barrier strategies. We outline materials, timeline, and what to expect during work.
Professional Installation
Our crew removes old vapor barriers, installs perimeter drains and sump pumps, applies heavy-duty liners, and seals all seams. Clean work area. Minimal disruption.

You'll always know what's happening next—and when.

Why Local Expertise Matters
West Linn is not Portland or Beaverton. Soil, hydrostatic pressure, and building patterns here are unique.
Willamette Valley Clay Soil
Heavy clay holds water and creates hydrostatic pressure. Standard drainage in other regions fails here. We use deeper systems and pump sizing matched to West Linn's soil behavior.
River Proximity & Seasonal Swings
Homes along the Willamette and Tualatin Rivers face groundwater surges during spring runoff. We account for seasonal water table spikes in Bolton and Willamette neighborhoods.
Vintage Home Challenges
Many West Linn historic neighborhoods (Willamette, Bolton) have 100+ year old foundations built with terra cotta or brick. These materials are porous. Modern vapor barriers and dehumidification work.
200+ Projects in Area
We know the neighborhoods. We've repaired crawlspaces in Marylhurst, Hidden Springs, and Barrington Heights. That experience saves money and time on your project.
Moisture damage compounds fast in Pacific Northwest homes. A damp crawlspace today becomes moldy, structural damage and rising energy bills within months.
