Now that your crawl space is empty and clean, it’s time to install the vapor barrier! A crawl space vapor barrier is essentially a durable piece of industrial polyethylene sheeting that is laid along the ground and up along the bases of the foundation walls to seal it from moisture.

They are an incredibly effective for preventing:

• Standing water in the crawl space
• Bad or musty odors
• Rotting wood on the ceiling of the crawl space
• Warped or sagging floors
• Rusted pipes in the crawl space
• Observable mold or mildew

As you can see, this one protective measure goes a long way protecting your property. Furthermore, it limits the amount of contaminants like mold and bacteria that would otherwise flourish in a damp environment.

If a member of your family is experiencing problems with allergies or asthma, your crawl space could be the culprit! The vapor barrier will help improve the indoor air quality in your home and prevent your family from breathing in harmful contaminants.

Beyond just protecting your home from structural issues and your family from health problems caused by excess moisture, installing a vapor barrier also turns your crawl space from a damp, dusty cave to a dry, viable storage space. You will now have a place to store your holiday decorations or out-of-season clothing without worrying that they will get covered in mold and smell terrible when you retrieve them next year!
