Drying up damp crawl space

Crawlspaces are need your attention too when it comes to home waterproofing and dampness. Crawlspaces are perfect spots for mold and mildew growth, especially if water can infiltrate into that space. Here are a few tips on how to dry crawlspaces.


An exterior drainage system can improve water seepage under your foundation. If you do have a drainage system installed, and moisture is present in your home, then you should improve the drainage system. Make sure that the soil is graded and also that the gutters are unclogged and do not redirect water near your home.

Foundation insulation

It’s also very important to insulate the foundation of your home. This will also prevent water seepage in your basement. You can also start insulating the walls of your home.

Crawlspace floor

Another thing that you can do is install a heavy-duty plastic on the floors of the crawlspace. This plastic is know as a vapor barrier. This barrier will stop moisture from entering the crawlspace.

Electric fan

If you want to get rid of the dampness in the crawlspace, you can use an electric fan. Leave it running for 10-12 hours and then the flow of air will dry any remaining moisture.


If you electric fan hasn’t succeeded in drying the crawlspace, then you can use a dehumidifier. This will remove all the moisture in the air and thus dry the walls and floor.
