Is Your Crawl Space Putting Your Family's Health At Risk?


A dirty crawl space can create dangerous air conditions within your home. High humidity below the ground can result in toxic mold spores that thrive in this environment. As a result, the moisture can leach from the soil, traveling through your home through porous foundations and structures as vapor.

If you are worried about the risk to your loved ones, Interstate Pest Management has the crawl space repair solution. Our licensed technicians will repair your crawl space and turn it into a healthy environment. After all, doesn't your family deserve to breathe clean air?

Keep in mind, wildlife animals and cats can also invade your crawl space. If this occurs, we can safely remove the pest and its nest from your crawl space and relocate it elsewhere. Then, we can perform exclusion techniques to help prevent the pest from returning.
