If you have a crawl space that has moisture problems, you need to keep the moisture out. This is because moisture can cause mold and mildew to grow and can attract some pests. The temperature of your crawl space also changes inside the crawl space. Below are three things you can do to prevent water from getting into your crawl space again. 

Remove Vent

If you have a crawl space vent, removing it will help. There are many ways you can remove a crawl space vent, and you may be able to do this on your own. Before you get started you will need a brick chisel and a hammer. Use the brick chisel to slowly remove the mortar around the exterior rim of the vent. Use the hammer to tap the chisel and you will start to see the mortar breaking away. Do not hit the chisel hard, however, as you do not want to cause other damage surrounding the vent. 

When the mortar is removed, use the claw at the end of the chisel to remove the vent. Remove mortar that may be left behind. There are vent covers that you can purchase to cover the hole that you just created. You can also hire a concrete contractor to completely fill in the hole. 

Waterproof Exterior Crawlspace

An excellent waterproofing method is to hire a professional to install a French drain. This works well in the ground around the foundation. This involves digging a trench around the foundation and placing a pipe into the trench. Gravel is placed over the pipe and the contractor then lays landscaping fabric over the gravel. Soil is placed over the landscaping fabric so the French drain is completely hidden.

A French drain works well, as it directs water away from your home to another area. This not only keeps water from getting into your crawl space through the foundation but can also prevent foundation problems due to standing water.

Encapsulate Interior Crawl Space

Encapsulating your interior crawl space will keep all moisture out. This involves installing a vapor barrier inside the crawlspace. This vapor barrier covers the floor, walls, and ceiling. Any seams are sealed with the vapor barrier. If you do not want to remove the crawl space vent above, the vapor barrier will also cover the crawl space vent. 

Once the vapor barrier is installed, the contractor will need to condition the air. They may install a dehumidifier, route a small amount of air from your HVAC system, or install a small exhaust fan. 

Both of these methods will work well to keep your crawl space dry and protect your home from water damage.
