Why Is My Crawlspace Wet Every Winter? (Silverdale, WA)

What usually causes wet crawlspace in Silverdale

Downspouts dumping at the foundation: a 2,000-square-foot roof sheds over a thousand gallons in an inch of rain. In Silverdale that usually means post-mall subdivision poly near Silverdale Way, and the ground, loose outwash on the Clear Creek flats, decides how far the water travels before you see it.

The second thing we rule in or out is grading that slopes toward the house. Decades of landscaping and settled backfill often reverse the slope in the first few feet around the foundation. It's common enough on acreage out Anderson Hill Road that we never skip it.

And a silted or outlet-less footing drain: corrugated pipe laid in native soil without fabric silts shut in a few decades, and the daylight outlet is usually buried or crushed. Less common on tight side yards full of irrigation, but we've found it near Anderson Hill Road.

First steps on a Silverdale property

Clear Creek's wetlands and the high winter water table near Dyes Inlet mean French drains need a real outlet; a dry well in that ground just fills.

What you can check yourself on tight side yards full of irrigation: check the slope of the ground against the foundation on all sides. Find the footing drain outlet and see whether it's flowing. If you get that far, we'll pick it up from there with cleanouts and outlet structures and sump basins where needed.

How we fix it

In Silverdale the work that follows the diagnosis is footing drain repair, and it runs in order: outlet, backfill with rock, remove and replace. Insert fittings with failed clamps in a winter water table close to the surface sets the pace on Ridgetop and Island Lake cul-de-sacs; the sequence doesn't change.

Our Silverdale coverage for wet crawlspace runs Anderson Hill Road, Bucklin Hill, Old Town, Ridgetop and everything between. We're based in Central Kitsap, our home base, with cleanouts and outlet structures and pumps on the truck.
