Crawl Space Vent Covers & Door Replacement Services in Alabama

A wooden crawl space access door can warp or rot from the weather outside thanks to excess moisture. They can also leak if not properly installed or sealed. This means your home is vulnerable to unwelcome pests and water damage. The same can be said about old or missing crawl space vent covers. In addition to nasty critters making their way into your home, a crawl space without durable doors and vent covers will also allow outside humid air into the basement or crawl space that will travel to the upper levels of your home. This is known as the stack effect, and it can be the source of mold, mildew and other costly damage.

Thankfully, our replacement crawl space vent covers and doors are waterproof, resistant to mold and will last for many years to come. When paired with a complete encapsulation system, you can rest easy that your crawl space will be completely sealed off from the harmful outdoor environment.
