Local risk profile
Maury County covers 613 square miles of central Tennessee, with about 107,791 residents and 46,159 homes. The county seat is Columbia, and Spring Hill and Mount Pleasant round out the largest towns. Much of its housing is recent, with a median build year of 1994.
49/100 Water Damage Risk Index: Elevated Maury County ranks 56 of 95 Tennessee counties. See the statewide ranking and method.The three factors where Maury County ranks highest compared with other Tennessee counties.
Pipe-freeze risk in Maury County sits near the middle of the state. From 2015–2024 it averaged 11 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 68 nights at or below 32°F. That ranks 45th of 95 counties.
Cold snaps are the real risk. The worst in the record lasted 6 days below freezing (ending February 2021), and the low bottomed out near -6°F on January 17, 2024.
Expect the hardest freezes in January, inside a season that runs December to February. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
Freezing nights typically start around Nov 1 and end around Apr 2.
Rainfall is about average for Tennessee. The county gets about 56.1 inches of rain and melted snow a year, with 14 days of an inch or more (49th of 95). Those downpours cluster in February, March and December, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.11 inches on March 28, 2021. The worst three-day stretch dropped 4.97 inches, ending February 24, 2022, the kind of soaking that overwhelms sump pumps and storm sewers.
About 64 days a year swing from below freezing at night to above freezing by day. Those freeze-thaw cycles feed ice dams on roofs, open cracks in foundations and driveways, and stress pipes that are already marginal.
Housing
35% of homes in Maury County predate 1980, below the Tennessee county median of 41.2%, which ranks 73rd of Tennessee's 95 counties.
Growth since 2000 added 42% of today's homes. In houses that new, the weak points are washing machine hoses, ice maker lines, water heaters and sump pumps rather than the pipes in the walls.
23% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
Manufactured and mobile homes make up 7% of the housing here. Water lines in the underbelly depend on intact skirting and working heat tape, and they're usually the first to freeze in a cold snap.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 72 times a year here, close to the Tennessee county median of 74. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectMain heating fuel in Maury County's occupied homes: 26% utility gas, 67% electric, 5% propane and under 1% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
