Water at the foundation in East Port Orchard, WA

The likely causes here

In East Port Orchard we check runoff and groundwater from uphill before anything else, because pressure dropping at the back of the house is how it shows up here. On sloped lots, a curtain drain uphill of the house intercepts it before it reaches the backfill. Till sloping toward Sinclair Inlet makes the signs misleading, so we confirm rather than assume.

Next: downspouts. The buried line is crushed, clogged or was never there, and roof water dumps at the wall. With clay seams near Retsil under mid-size lots along Bethel Avenue, the symptoms can look identical to the first cause, which is why the meter test and the locate matter.

Finally, grading. The ground slopes toward the house in the first few feet. Worth five minutes before anyone digs subdivision backfill over hardpan.

What to check first

Interceptor drains on the uphill side and properly outleted footing drains are the standard fix.

Do this before anyone digs subdivision backfill over hardpan in East Port Orchard: watch the downspouts in a hard rain. Check the slope against the wall on every side. It takes minutes and it tells us whether the problem is on 1980s subdivision lots off Mile Hill or inside the house.

The fix in East Port Orchard

The repair side is downspout drain line repair. On sloped lots above the inlet that means excavate, then replace in hardpan on the Mile Hill plateau where the problem actually is, then backfill and restore. If what we expose is galvanized on Annapolis waterfront homes at the end of its life, we say so with the pipe in your hand.

From Bethel Avenue to South Kitsap High and out around Mile Hill Drive, water at the foundation is a regular East Port Orchard call for us. About twenty minutes across the inlet, and emergencies on mid-size lots along Bethel Avenue dispatch immediately, any hour.
