Can a crawl space flood?
Regarding this, is it normal for a crawl space to flood?
A flooded crawl space after heavy rain may be all too common in many homes, but it is not “normal.” Theoretically, the crawl space under your house is designed to stay dry in all weather. Rainwater pooling around the foundation seeps into the crawl space through cracks and other openings.
Beside above, is water in crawl space bad? Standing water in the crawl space of any home can lead to mold and mildew growth - which, in addition to being a potential health hazard, can become the cause of rot and structural damage. If you're considering buying a home with standing water in the crawl space, then you should also be on the lookout for mold.
Keeping this in consideration, how do you keep a crawl space from flooding?
- Keep water away from your home's foundation. Allow rain water to flow away from your house by making sure your gutters work, you have downspouts properly installed, and that your lawn slopes away from your foundation.
- Install a vapor barrier.
- Install a crawlspace sump pump.
Should crawl space vents be open or closed?

So our answer is to open and close the vents in your crawlspace seasonally, instead of deciding to seal off crawl space vents altogether.
