EPA suggests leaving growth larger than about 10 square feet to a professional. Call the number on this page to be connected with a local mold remediation company in Arrington.

What happens when you call
Your call connects you with an independent remediation company serving Williamson County. Start with what you've seen: where the mold is, how large an area, and whether there was a leak, a storm or a plumbing failure. If you aren't sure where the water is coming from, mention it; some companies will suggest an inspection first.
At the visit, the company should take moisture readings, look in the crawl space or basement and attic, and walk you through what has to be cut out versus cleaned. Get the scope, containment plan and drying check in writing before work starts.
Cost factors
- Square footage. Angi's national figures run $1,223 to $3,758 for a typical job and $10 to $25 per square foot.
- Location. Basements nationally run $500 to $3,000, walls $1,000 to $20,000.
- Finished spaces. Bonus rooms and finished basements mean more drywall, trim and flooring to remove.
- Rebuild. Ask whether it's included.
Middle Tennessee prices vary. Williamson County isn't among the counties TDCI lists for the Home Improvement license on smaller home jobs, but projects of $25,000 or more need a Tennessee contractor's license, and S-F is the mold remediation classification.

Local conditions in Arrington
Arrington is a small, historic unincorporated community near Franklin, first settled as Petersburg and renamed for a nearby creek. Today it mixes rural properties with a gated subdivision of more than 420 homes beside Kings' Chapel. Williamson County emergency management says the Harpeth River and its creeks are the main flood sources in the county, flash floods can come with little warning, and blocked culverts, ditches and drains cause flooding too. It also points out that most creeks are the property owner's responsibility. The county notes that the May 2010 flood showed 20 inches or more of rain can fall in two days.
As an unincorporated area, Arrington gets building permits for any rebuild from the Williamson County Building Codes Division on West Main Street in Franklin.
