Storm & Flood Damage Recovery in Seattle, WA

Duration, not a burst. Weeks of light rain keep the uphill bank saturated, so the buried wall of a daylight basement is holding groundwater, not shedding a single cell. The first sign is usually damp at the base rather than a visible flow. Perimeter drainage at the cut and a working sump manage that bank; waiting for a named storm to explain the wet wall will miss the season that never stops.

Often both, and they look alike on the floor. The cut face takes uphill groundwater all season; moss-packed gutters and a roof seam that never dries add a second path from above. A moisture map tells which wall is feeding the room. Extraction still starts with standing water; the lasting split is whether the fix is a drain at the buried wall or a cleared gutter and a dried roof cavity.

Yes, once they overflow at the eaves. A packed gutter turns the roof edge into a waterfall a few inches from the siding, and on a slope that sheet runs to the downhill wall or back toward the cut. Wood-frame assemblies here do not get a dry week to recover. Clear the debris and carry the downspout past the wall; a ceiling stain after a quiet November is often that overflow, not a failed shingle in the field.
