Is sealing your crawl space a good idea?



Crawl space encapsulation is the best idea to keep your home free from moisture and mold. It involves installing a vapor barrier on top of it, as well as sealing any cracks or openings for no more leaks inside!

Crawl space encapsulation isn’t always the right answer for every home. If your crawl space is particularly wet or has significant water damage, it’s best to consult a professional to see if this is the best option for your home.

One alternative to crawl space encapsulation is to install a drainage system, which can help keep the crawl space dry and reduce the risk of mold and mildew growth risk. Consider using a dehumidifier in the crawl space to help control moisture levels or fans to circulate air and keep the space dry.
