Crawl Space Mold Removal in Antioch, TN

What's under Antioch homes

About 63.8 percent of homes in the Antioch (Priest Lake) area were built before 1980, and many crawl spaces from that era have thin plastic barriers, open vents and decades-old insulation. The same area has a sizable share of mobile homes, roughly 11 percent, where the space under the floor is enclosed by skirting and the ducts run through the underbelly.

Mill Creek is the water to know. In May 2010 its Antioch gauge set a record crest of 26.10 feet, and the National Weather Service documented flooding in the Mill Creek area. In March 2021, flash flooding rescued people from trees on Harding Place and sent Mill Creek rising sharply again. Metro Water Services publishes FEMA flood maps and the Parcel Viewer, and notes that homes outside a mapped flood zone can still flood.

Clean it or remove it?

Replacing joists or other load-bearing members needs a permit from Metro Codes.

Signs to look for

• A smell that's worse on hot, humid days or when the AC runs.
• Soft floors near bathrooms and the kitchen.
• Sagging skirting or a wet, torn underbelly on a mobile home.
• Silt or a water line on piers after heavy rain.

Timing

After any heavy rain or flood, act fast: EPA says to dry wet areas within 24 to 48 hours and to assume mold is growing if that isn't possible. Summer is when condensation peaks, so a space that looks fine in March can be wet by July. Renters whose landlord won't fix a leak or standing water can report it to Metro Codes Property Standards through hubNashville. Metro Public Health's "Mold, Moisture, and Your Home" handout is a good next read. Davidson County is one of the counties where residential jobs from $3,000 to under $25,000 need the state Home Improvement license, so ask for the license number and look it up on TDCI's Verify a License search.
