Groundwater & Basement Water Intrusion in Kirkland, WA
Basement seepage, failed sumps, and hydrostatic pressure against the foundation are extracted and dried, and the path from the ground is identified so the loss does not repeat. Groundwater and basement seepage are extracted and dried only after the path from the soil is identified — a wall, a slab, a drain, or a failed sump. Drying the interior without stopping that path returns the same water to the same floor.
Frequently asked questions
The lake is deliberately higher in summer than in winter.
That is deliberate. The level is held up through the warmer months and lowered for the winter, on a schedule set well away from here and published in advance. For a shoreline property it means the relevant level is the summer one rather than an average, and it means a winter storm meets a lake with room in it rather than a full one.
From October to April it is simply always wet.
That is the climate rather than a defect, and it changes when to act rather than whether. A fault found in November has five uninterrupted months to work on the building and nothing will dry on its own during them. So a repair that could reasonably be deferred in a drier place cannot be deferred here: waiting for good weather means waiting for April, by which time the cost has changed.
Water arrives at the uphill wall rather than the floor.
On these slopes the water is moving sideways through the ground rather than rising from beneath. It works down through looser material, meets a denser layer it cannot pass, and runs along the top of that until something interrupts it, which is the uphill wall of a daylight basement. Interception above the building is what deals with it; work on the floor does not.
