7% of occupied homes in Bedford County heat mainly with wood or propane, close to the Tennessee county median of 7.8%.
With 75 muggy nights a year, mold in Bedford County can appear within days of a leak. Dry first, then clean.
Local risk profile
About 52,237 people live in Bedford County, 474 square miles in southern Tennessee, in roughly 20,488 homes. The county seat is Shelbyville, and Unionville, Wartrace and Bell Buckle round out the largest towns. Much of its housing is recent, with a median build year of 1990.
48/100 Water Damage Risk Index: Elevated Bedford County ranks 57 of 95 Tennessee counties. See the statewide ranking and method.The three factors where Bedford County ranks highest compared with other Tennessee counties.
Pipe-freeze risk in Bedford County sits near the middle of the state. From 2015–2024 it averaged 10 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 67 nights at or below 32°F. That ranks 56th of 95 counties.
The longest cold spell was straight 4 days without the temperature rising above freezing, ending in February 2021. The coldest night reached about -7°F on January 17, 2024. Burst pipes usually show up when a spell like that breaks and the ice thaws.
Most freezing nights fall from December to February, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
Freezing nights typically start around Oct 31 and end around Apr 1.
Rainfall is about average for Tennessee. The county gets about 59 inches of rain and melted snow a year, with 14.6 days of an inch or more (36th of 95). Those downpours cluster in February, March and December, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.24 inches on March 28, 2021. The worst three-day stretch dropped 6.91 inches, ending September 21, 2021, the kind of soaking that overwhelms sump pumps and storm sewers.
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 63 times a year here. They're the main driver of ice dams and of water working its way through foundation cracks in late winter.
Housing
36% of homes in Bedford County predate 1980, below the Tennessee county median of 41.2%, which ranks 72nd of Tennessee's 95 counties.
33% of homes were built in 2000 or later, more than in most of Tennessee. Newer plumbing rarely corrodes, so damage here tends to come from appliance supply lines, water heaters, sump pumps and storms.
The 1980s and 1990s account for 32% of the county's homes. If yours is from those decades, look under the sinks and at the water heater for gray plastic pipe stamped PB, which is polybutylene and leak-prone.
11% of homes are manufactured or mobile homes, below the Tennessee county median of 15.9%. Their water lines run under the floor behind the skirting, so a torn skirt or failed heat tape freezes them faster than lines in a site-built house.
Beyond water
About 75 nights a year in Bedford County stay at 65°F or warmer, a sign of muggy summer air (42nd of 95 counties). February is the wettest month. The EPA recommends keeping indoor humidity below 60%, ideally 30 to 50%. Basements can pass 60% on their own in summer, so a dehumidifier matters even without a leak, and anything wet should be dried within 24 to 48 hours.
Mold remediation: what to expectBy main heating fuel, Bedford County homes break down as 16% utility gas, 76% electric, 6% propane and 2% wood. Most homes here heat with gas or electricity, so cooking and electrical faults are the likelier fire sources. Even a contained kitchen fire can send soot through the ductwork to every room.
