Vapor Barrier

If your home has a crawl space instead of a full basement, you may have excess moisture. As water evaporates, it rises up through your house and too much moisture coming into and up from your crawl space can lead to problems with rust, corrosion, rot, and mold.

Rust and Corrosion

Crawl spaces aren’t simply empty spaces beneath homes; some have HVAC equipment like ductwork or even plumbing and electrical components in them, all of which can become rusted and corroded by too much moisture in the air.


Excess moisture can also be devastating to your floor joists, subfloor, posts, and beams, which are all made of wood. We all know that water mixed with wood makes wood rot and if your floors start to rot out from under you, you’ve got an expensive fix on your hands that your homeowner’s policy won’t cover.


Mold can be a big problem in damp houses, and leaving it unmitigated can cause many health problems including allergies attacks, respiratory problems, eye and skin irritations, coughing, and wheezing. Removing mold isn’t enough as it will eventually come back if you haven’t taken any steps to lessen the dampness in the air

This is where a vapor barrier can help. A vapor barrier is a sheet of plastic securely placed over the damp soil, the thicker the plastic, the more durable it will be. It’ll keep your crawl space dry which will, in turn, help you have a drier house. Vapor barriers can also help with radon mitigation. If you’ve had your home tested and you’ve found out you have a problem with radon, a good vapor barrier in your crawl space is used in conjunction with pipes and fans to suck the radon out of your crawl space and outside where it can’t do you any harm.

When it comes to installing a vapor barrier, most people leave it to the professionals. Crawling around in a crawl space laying down plastic is a difficult job; it’s hard on the back and it’s not easy creating a barrier without open spots. Our professional, experienced technicians can install a vapor barrier with no leaks that will not only protect your home from the damaging effects of moisture but your crawl space will be a cleaner place too!
