Crawl Space Encapsulation in Knoxville TN

You might wonder if you need to encapsulate your crawl space or not. This is useful for any house, but you should do it especially if you are struggling with mold, musty smell, or insect problems. Some other warning signs include separating floors, high heating costs, or sweating windows.

Before you begin working, check to see if the crawl space area needs any additional work before the encapsulation. If you notice water problems, make sure you check the outdoor drainage system.
