Key takeaways
- A sump pump moves collected water out of the space
- A French drain intercepts water before it reaches the house
- Many wet crawl spaces use both
- Gutters and grading are often the cheapest first fix
Wet crawl spaces have a few common causes and a few common tools.
Sump pump
A pump in a basin collects water and sends it out through a discharge line.
French drain
A buried perforated pipe in gravel intercepts water in the yard or along the footing.
Both
A drain catches water and a pump moves it, so many systems use the pair.
Start outside
Gutters, downspouts and grading often do a lot of the work for little cost.
