Heavy rain on hilly terrain floods creeks and rivers quickly, from Nashville to rural Middle Tennessee.
In Nashville: The May 2010 flood caused billions in damage, and creeks like Mill Creek and the Harpeth River still flood in heavy rain. In Memphis: Heavy rain floods low streets and creeks like Nonconnah Creek. In Knoxville: Steep lots channel stormwater toward foundations, flooding basements and crawlspaces. In Chattanooga: Heavy rain floods creeks like Chattanooga Creek and South Chickamauga Creek.
Crawlspaces and basements are both common, with fast-growing suburbs around Nashville and Knoxville adding many newer slab and basement homes.
Tennessee requires contractors on projects of $25,000 or more to be licensed by the Board for Licensing Contractors. Home improvement work in some counties needs a separate home improvement license.

Sewage & Biohazard Cleanup questions
Does homeowners insurance cover flood damage in Tennessee?
No. Flood requires an NFIP or private flood policy. In 2010, many Nashville homes that flooded were outside high-risk zones.
How do I verify a Tennessee contractor?
Search the Tennessee Board for Licensing Contractors, and ask about home improvement licensing if your county requires it.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
