Crawl Space Concerns in Washington

The Pacific Northwest receives more sustained rainfall than almost any other US region. Without active drainage, water continuously migrates into crawl spaces through soil pressure alone. Drainage systems are not optional here — they are essential infrastructure.

!Annual rainfall of 35–60+ inches keeps soil perpetually saturated
!Hydrostatic pressure pushes groundwater into crawl spaces through floors and walls
!Moss, mildew, and wood rot are endemic due to constant dampness
!Many older homes have insufficient drainage systems for the rainfall volume
!Douglas fir framing (common in PNW) is particularly susceptible to moisture damage

Local Tip — Washington

In the PNW, a drainage system should be considered mandatory, not optional. French drains or interior perimeter drains with a sump pump are the standard approach. Pair with encapsulation for complete moisture control.
