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 how that plays out in Glen Ellen & Kenwood, what to do right now, and how to reach an independent, licensed local provider. Call (628) 336-1777 any time, or use the form on this page.
Crawlspace flooding in Glen Ellen & Kenwood: what we see
Homes in Glen Ellen and Kenwood sit on hillsides and along Sonoma Creek and its tributaries. Hillside runoff can reach crawlspace vents fast in intense rain, and slopes burned in 2017 changed how some sites drain.

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 After a flood: cleanup safety. We also have a storm-season article: How to use sandbags.

Frequently asked questions
Is a burned hillside still a runoff risk years later?
Burned slopes recover over time, but runoff depends on the site. Have drainage checked if your home sits below a slope.
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.
