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.
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.
