Subfloor and Under-House Water Leak Repair FAQ Guide for Homeowners
How does crawl space water extraction work?
Submersible pumps remove standing water, then wet-vacs pick up the rest so drying can begin.
Are subfloor drying services always needed after a leak?
Almost always, since wood and concrete hold moisture after visible water is gone and cause problems later.
Can a foundation leak cause subfloor damage?
Yes. Water through a foundation crack soaks the crawl space soil and raises humidity that wets the subfloor.
What are signs of a water leak under my house?
Musty odors, higher humidity, pooling in the crawl space, soft floorboards and an unexplained jump in the water bill.
What's the difference between extraction and drying?
Extraction removes liquid water, while drying removes the moisture absorbed into wood and concrete, which takes longer.
