Foundation Repair & Drainage in Edmonds

Edmonds projects split between the City of Edmonds and Snohomish County depending on the parcel, and Woodway and Lake Forest Park add their own review paths. Identifying the right authority early avoids a submittal that goes to the wrong desk and stalls a schedule by weeks.

Above the shoreline, the controlling issue is usually water rather than load. Runoff from uphill streets, downspouts discharging near the top of a bank, and perched water sitting on a clay layer all concentrate at the wrong place. Interceptor drainage uphill of a structure frequently does more good than anything installed at the footing itself.

Where a bluff parcel raises genuine slope-stability questions, we coordinate with a geotechnical engineer rather than working around the question. A pier supports a designed load; it is not a slope repair, and we will not present it as one.

The Edmonds Bowl carries a mix of pre-war cottages and mid-century homes, while Perrinville, Woodway, and the Shoreline corridor lean toward 1950s through 1980s construction with daylight basements and crawl spaces. Newer view homes above the water sit on engineered footings, often with retaining structures that are part of the building's load path.

Clay and glacially derived fine-grained soils show up at footing depth in many of these lots. Clay is not uniformly weak or impermeable, but where it holds water above a less permeable layer, seasonal movement and wet crawl spaces become recurring problems.

The findings we record most often here are saturated crawl spaces with framing decay, retaining walls leaning where drainage behind them has failed, and differential movement at additions built onto an original footing.
