Crawl Space Encapsulation

Eliminating Moisture From The Ground Up

As you might expect, homes built over an open crawl space are extremely vulnerable to problems stemming from excess moisture and humidity – especially homes located in the Southeastern part of the country.  Rotten wood, musty smells, water condensation, and mold formation are just a few of the typical issues that occur in a ventilated crawl space. These problems also impact the safety, indoor air quality and energy efficiency of the entire house

Crawl Space Encapsulation

Crawl space encapsulation involves sealing up the walls and open floor of a crawl space to prevent the introduction of moisture. Installing this “vapor barrier,” along with a small exhaust fan or an energy efficient dehumidifier helps prevent the formation of mold, and keeps airborne allergens from entering through crawl space vents (since they will have been sealed). The regulated air quality in the crawl space translates into better indoor air quality for the entire house.

While crawl space encapsulation is a viable solution in many instances, it also requires a sizable financial commitment. It’s worth having a building scientist do a home energy audit to determine exactly what your performance issues are and how they can be fixed. Perhaps encapsulating your crawl space is the best plan of action, or maybe there’s a less expensive tactic that will serve you just as well.

If you’re having moisture issues in your crawl space, or trying to eliminate them before they start, contact your local Elm Energy office. Not only do we provide whole crawl space solutions, we also provide low cost inspection services that look at a host of additional factors.
