What you can do
Stay out
Crawl spaces can hold standing water near wiring, sewage, pests and sharp debris. Let the crew go in.
Note the smell
A sewage smell changes how the job is handled. Mention it.
Tight spaces and hidden hazards
Crawl spaces may have energized wiring, standing contaminated water and poor air. Do not enter if water is near wiring or you smell sewage or gas.
Common sources
Plumbing leaks
Supply or drain lines under the floor.
Groundwater and rain
Poor grading, gutters draining toward the house.
Condensation
High humidity on pipes and ducts.

Call 833-877-1717Crawl space water questions
Is water in the crawl space serious?
Yes. It raises humidity in the house, can rot floor framing and feeds mold.
Can I call about crawl space water at night?
Yes. You can call 833-877-1717 at any time, including nights, weekends and holidays. Whether an independent provider can come out right away depends on your ZIP code, the time and provider capacity, so availability is not guaranteed.
Does wet insulation need to be replaced?
Usually. Soaked fiberglass insulation sags and holds moisture.
How do I keep the crawl space dry?
Fix drainage and gutters, repair leaks, and consider a vapor barrier or encapsulation. Providers can advise.
