Why Is There Water In My Crawlspace?

Well, if you’ve tackled the task of inspecting your crawlspace, and noticed excessive moisture or standing or pooling water, you may be asking yourself….Why is there water in my crawlspace? How does it get in there?

The water enters under the footing, between the footing and the walls. It comes in through cracks, and even through the ventilation grates. Once it gets in, it just pools and puddles. It doesn’t evaporate very quickly.

Surface Flooding: The ground can’t always absorb the heavy rains fast enough, allowing it to seep in (or flow in). Sprinklers that constantly hit the home or built in planters that are against the home.  When the planters or flower beds are constantly watered, the water eventually will make its way into the crawlspace.

Poorly Graded Homesites: Your home is supposed to be graded so that the slope directs water away from your foundation. If this is done incorrectly, or if erosion has happened over time, water can flow directly towards your home and into your crawlspace.

Improperly Installed Rain Gutters And Downspouts: Overflowing or clogged rain gutters, missing or lack of rain gutters can cause damage. Without the rain gutters working efficiently, the rain will flow off the edges of your roof and onto the ground around the perimeter of your home.

Broken Water Lines Or Water Heater: If you notice that the pooling, puddling water is found directly below a tub, shower, toilet or other plumbing fixtures, or beneath drain pipes, you are probably dealing with a plumbing-related water problem. Even if the pipe burst in an upstairs bathroom, it will eventually find its home in the crawlspace. I would shudder at the thought of a possible sewer line breakage or septic tank leak finding its way Into the crawlspace, but it’s possible.

Outside Of Regular Maintenance: Make sure your gutters are cleaned out, and check the grading around the perimeter of your home. After the rainy season, check for erosion.
