Crawlspace flooding in Kentfield, CA

Water under the house is easy to miss and slow to leave. It raises humidity indoors, soaks floor framing and insulation, and can lead to mold. Here's what that looks like in Kentfield, what to do, and how to get connected with an independent, licensed local provider.

Crawlspace flooding in Kentfield: what we see

Kentfield homes along Corte Madera Creek and on the valley floor can see high groundwater and creek-related water during major storms, while hillside homes in Kent Woodlands catch runoff from steep slopes above. Older homes here often have crawlspaces with original or no vapor barriers.

The local picture

Slopes and runoff. Where water comes from depends on where the house sits. Kentfield spans the lower Ross Valley floor along the creek, rising steeply into wooded hills to the south and west.

Creeks, tides and groundwater. Proximity to water affects groundwater and flood risk under the house. Kentfield is shaped by Corte Madera Creek, which runs past the College of Marin and has a history of flooding in big storms, plus hillside drainages.

Conditions vary a lot from street to street in Kentfield, so a provider should assess your specific home.

What to do right now

  1. Don't enter a flooded crawlspace if wiring may be wet or if the water could be sewage or floodwater.
  2. Photograph the water level from the access hatch.
  3. Check your sump pump and its power, if you have one.
  4. Fix obvious sources you can reach safely, like a disconnected downspout.
  5. Call for professional pumping and drying.

Kentfield checklist

  • If you're near the creek, keep anything stored in the crawlspace off the floor, or don't store anything there at all.
  • Clean gutters and extend downspouts well away from the foundation.
  • Make sure soil slopes away from the house.
  • Check that the vapor barrier covers the soil and isn't torn.
  • Look under the house after the first big storm of the season.

How a provider handles it

Providers pump out the water, remove wet insulation and damaged vapor barrier, clean framing (and treat it after contaminated water), and dry with dehumidifiers while monitoring moisture in the wood. Lasting fixes usually involve drainage work. For the full picture, read our complete guide and the deep dive on crawlspace flooding in Marin. We also have a storm-season article on gutters and drainage for hillside homes.

Before you hire anyone, check the license on the CSLB website. Here's how we vet providers.

Frequently asked questions

Is my Kentfield home in a flood zone?

Check the FEMA Flood Map Service Center by address, and ask your insurance agent.

Is water in the crawlspace covered by insurance?

It depends on the cause. A sudden plumbing failure is treated differently from groundwater or outside flooding. Check your policy.

Will this cause mold?

Damp crawlspaces are a common source of mold. Dry it out and fix the source. See our sister site's crawlspace mold guide.
