Seattle Foundation Repair & Waterproofing

It comes down to our soils and weather: dense glacial till and clay swell and shrink with moisture, our heavy rain and high water table keep the ground saturated, and hilly terrain drives settling. Together they put constant stress on foundations and basements.

It depends on the problem and the method, but most repairs land between roughly $3,000 and $15,000 — a basement drainage system or crack repair on the lower end, full piering or exterior waterproofing on the higher end. Your free inspection gives you a firm written price, and financing is available.

Usually not when the cause is gradual settling, soil movement, or seepage — insurers treat those as maintenance. Sudden, accidental damage is sometimes covered. We'll document everything for your claim either way.

We work year-round in Seattle. Drier summer months make exterior excavation and drainage easier, but interior repairs and waterproofing can be done in any season — and a wet basement shouldn't wait.

Almost always. Foundation and water problems only get worse — and more expensive — over time, and they affect the value and safety of the whole home. Fixing it properly protects your biggest investment.

Yes — every inspection is free, with no cost and no obligation, usually scheduled within 24–48 hours. Call or use the form to book yours.
