Is Water in My Crawl a Bad Sign?

Of course, a little bit of water won’t cause a problem with the structure right away, but it can cause mold to grow much faster than you might think. Mold can start to grow in as little as 24 to 48 hours, according to FEMA. That means that even a small amount of water can cause a lot of trouble if you let it sit there and grow. The safest thing you can do for your family and your home is to make sure a good waterproofing system is in place.
