With 9% of homes built before 1960 and about 6 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
Basements flood here mostly in December. Limestone County averages 14.9 days a year with an inch of rain or more.
9% of homes here predate 1960, when clay and cast iron sewer laterals were standard. Roots and cracks in those lines are a common cause of backups.
Limestone County's wettest day in the 2015–2024 record brought 4.1 inches, and about 50 freeze-thaw days a year mean ice dams in some winters.
7% of occupied homes in Limestone County heat mainly with wood or propane, below the Alabama county median of 9.9%.
About 94 nights a year here stay at 65°F or warmer, so basements and crawl spaces can grow mold even without a leak.
Local risk profile
Limestone County covers 563 square miles of northern Alabama, with about 111,233 residents and 44,354 homes. Athens is the county seat; Ardmore, Elkmont and Lester are the next largest communities. Much of its housing is recent, with a median build year of 1998.
44/100 Water Damage Risk Index: Moderate Limestone County ranks 43 of 67 Alabama counties. See the statewide ranking and method.The three factors where Limestone County ranks highest compared with other Alabama counties.
Limestone County gets more hard-freeze nights than most of Alabama. From 2015–2024 it averaged 6 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 52 nights at or below 32°F. That ranks 4th of 67 counties.
The longest cold spell was straight 3 days without the temperature rising above freezing, ending in February 2015. The coldest night reached about 3°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 January, 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 Nov 9 and end around Mar 22.
Rainfall is about average for Alabama. Of roughly 59.6 inches of yearly precipitation, the damage comes from the 14.9 days a year with an inch or more, ranked 36th of 67. February, March and December see the most. The single wettest day in the record: 4.1 inches, December 26, 2015. The worst three-day stretch dropped 6.25 inches, ending February 22, 2019, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 50 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
26% of homes in Limestone County predate 1980, below the Alabama county median of 43.5%, which ranks 63rd of Alabama's 67 counties.
47% of homes were built in 2000 or later, more than in most of Alabama. 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 27% 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.
Manufactured and mobile homes make up 9% 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 94 times a year here, below the Alabama county median of 112. Mold grows when indoor humidity stays above about 60%, the EPA's ceiling. A basement dehumidifier set to 50% and drying anything wet within 24 to 48 hours prevents most problems.
Mold remediation: what to expectMain heating fuel in Limestone County's occupied homes: 16% utility gas, 77% electric, 6% propane and under 1% wood. Fires here are likelier to start in the kitchen or the wiring than in the furnace. After any fire, keep the HVAC off until ducts are checked, or soot will travel through the house.
