Basement waterproofing in Silverdale: what to know
Water that comes from roof runoff often shows as stains beneath the eaves and at the same spot after rain. Seepage from a slope often shows as a damp band that grows after heavy rain. During wet weather we watch the wall, check the gutters and grade, and test the ground where it meets the footing.
A footing drain works only when its outlet stays open and falls toward a discharge that does not return water to the foundation. We clear the run, confirm its fall, and log the outlet. A public storm connection needs a permit under KCC 12.10.030(2), so that tie-in waits for county direction.
Permits and rules in Silverdale
Before quoting, we check each trench, any spoil placement, and the outlet route against the county’s 150-cubic-yard grading line and its exemptions. Any public storm connection is listed as its own item. We confirm the answer with county staff and file the reply with the parcel record.
Rules change and vary by parcel, so we confirm the current requirements with the city before we start.
How we approach it
- Sort roof water from slope water before choosing a fix
- Log the wall through a wet period before the repair
- Clear and regrade the footing line where it drains
- Hold any public storm connection for county direction

Questions from Silverdale homeowners
What makes a Silverdale basement wall sweat after a storm?
Stains beneath the eaves usually point to roof water landing near the foundation, while a damp band that grows after heavy rain usually points to slope seepage or ground moisture. Each pattern gets a different repair, so we identify it first. One patch rarely solves both.
Does the county grading line reach a Silverdale basement dig?
Kitsap County’s grading brochure sets a permit at 150 cubic yards or more and exempts excavation below finished grade, subject to its listed conditions, including the one-acre limit. We total the cut and fill, confirm the exemption with county staff in writing, and then schedule the crew.
Could a Silverdale footing drain discharge into a county storm pipe?
Only with county direction, because a connection to a public storm drainage system needs a permit under KCC 12.10.030(2). We weigh the lot’s own outlet options first, then set out each one with its drawbacks on paper.
