Flooded Basement Cleanup in Bothell, WA

Flooded basement cleanup in Bothell usually means a finished lower level: a family room with carpet, a bedroom, a laundry room and the furnace, often with a door out to the backyard on the downhill side. True full basements are less common here than crawl spaces, but split-levels and daylight-basement homes on the slopes of Westhill, Norway Hill and the hills above the Sammamish River have plenty of below-grade space. Through our referral line (opening soon), you can be connected with an independent local restoration provider to remove the water and dry the lower level properly.

Why Bothell basements flood

• Saturated hillsides. After weeks of rain, water moving downhill through the soil presses against basement walls and finds cracks, cold joints and the gap where the wall meets the slab.
• Blocked footing drains. Older perimeter drains clog with silt and roots. When they stop carrying water away, it builds up under the slab.
• Sump pump failure. A pump that burns out, a float that sticks or a power outage during a windstorm can let the pit overflow within hours.
• Window wells and lower-level doors. Wells without drains or covers fill like buckets; patio doors on the downhill side take water when the yard drain backs up.
• Plumbing inside. Water heaters, laundry and the main water line often sit in the basement.
• Sewer backup. A floor drain that backs up brings contaminated water — see sewage backup cleanup.

What cleanup involves

1. Power to the lower level is confirmed off before anyone wades in.
2. Standing water is pumped out, then carpet and pad are extracted. Pad that has been under groundwater is usually removed.
3. The water category is assessed. Groundwater and surface water are treated as contaminated, which means porous materials they touched are usually discarded.
4. Drywall is cut above the wet line ("flood cut"), and wet insulation behind it is removed.
5. The slab, framing and remaining drywall are dried with dehumidifiers and air movers, with readings each day.
6. Surfaces are cleaned and treated with an antimicrobial before rebuild.

Concrete holds a lot of water and dries slowly. Expect a basement to take longer to dry than an upstairs room, and do not reinstall flooring until the slab has been tested.

Protect your belongings

Move anything you can to a dry floor. Photograph damaged items before you throw them away, and keep a list for your claim. Cardboard boxes stored on a basement floor fail fast; plastic bins on shelves are the lesson most homeowners take away from a flood.

Stopping it next time

Keep gutters clear, extend downspouts well away from the house, test the sump pump every fall before the rains, consider a battery backup pump, and add drains or covers to window wells. If water keeps coming through the walls, a drainage or waterproofing contractor can assess footing drains and grading.
