How the work is handled

How crawl space water removal is handled in Redmond, WA

  1. MI1

    Pump the low point

    The crawl space crew sets a submersible pump and clears the pooled water.

  2. MI2

    Pull wet materials

    Soaked batts and failed vapor barrier come out so the framing can dry.

  3. MI3

    Dry the framing

    Dehumidifiers and air movers run until joists and subfloor reach the goal.

Education Hill, Grass Lawn and Idylwood are full of 1960s to 1980s homes built over vented crawl spaces, and much of the ground under them is glacial till: a dense hardpan that water cannot soak into. After a long run of winter rain, groundwater perches on the till and seeps up into the crawl space, or a downspout that dumps at the footing sends roof water straight under the house. A broken supply line under the floor does the same thing faster.

Why crawl space water is a real loss

  • Standing water keeps the air under the house near saturation, and that moisture moves up into the subfloor
  • Fiberglass batts between the joists soak up water, sag and stop insulating
  • Wet joists and subfloor can start growing mold within 24 to 48 hours in mild weather
  • Ducts running through the crawl space can pull damp, musty air into the living space

How the crawl space is cleared and dried

The crawl space crew sets a submersible pump at the low point and clears the pooled water, then pulls insulation and any vapor barrier that is torn, buried in mud or holding water. The drying team runs LGR or desiccant dehumidifiers and air movers aimed at the joists, with the vents closed so the equipment is not fighting outside air. Readings on the joists and subfloor are logged daily until they reach the drying goal.

Keeping it from coming back

Once it is dry, the fix is usually outside: downspout extensions, regrading so the ground falls away from the foundation, a perimeter drain or a crawl space sump, and a new vapor barrier. The Department of Energy insulation page covers crawl space insulation options, and EPA mold information explains why damp crawl spaces matter for indoor air.

Questions

Crawl Space Water Removal questions in Redmond, WA

Is a little water in the crawl space normal in winter?

Damp soil is common, but standing water is not. Pooled water on the vapor barrier keeps the air under the house saturated and should be pumped out and the source found.

Does wet crawl space insulation have to be replaced?

Soaked fiberglass batts usually come out. They hold water against the subfloor, sag out of place and lose their insulating value, so they are removed and replaced after drying.

Can the house be lived in during crawl space drying?

Usually yes. The equipment runs under the house, and the vents are closed so it can dry the space efficiently.

Is crawl space water covered by insurance?

Water from a broken pipe is often covered. Groundwater and seepage usually are not. Coverage depends on your policy, so it is worth checking with your own insurer.

Why does the crawl space flood after big storms?

Much of Redmond sits on glacial till that water cannot soak through, so rain perches on it and moves sideways into the lowest open space, which is often the crawl space.

Will a sump pump fix it?

A crawl space sump with a perimeter drain handles groundwater well. It works best alongside downspout extensions and grading that sends roof water away from the foundation.
