Casey County averages 20 nights a year at 20°F or colder, mostly December to February, and 15% of its homes predate 1960.
February brings the most downpours to Casey County, part of 12.7 heavy-rain days a year. Check the sump first.
15% 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.
In Casey County, 2.78 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
19% of occupied homes in Casey County heat mainly with wood or propane, above the Kentucky county median of 12.6%.
About 56 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
About 15,914 people live in Casey County, 444 square miles in southern Kentucky, in roughly 7,420 homes. Liberty is the county seat. Much of its housing is recent, with a median build year of 1985.
47/100 Water Damage Risk Index: Elevated Casey County ranks 77 of 120 Kentucky counties. See the statewide ranking and method.The three factors where Casey County ranks highest compared with other Kentucky counties.
For frozen pipes, Casey County is a typical Kentucky county, which is still plenty. From 2015–2024 it averaged 20 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 84 nights at or below 32°F. That ranks 50th of 120 counties.
On February 19, 2015 the low fell to about -9°F, and in the stretch ending February 2021 the county went 9 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
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.
On average the first fall freeze arrives around Nov 2 and the last spring freeze around Apr 15.
Rainfall is about average for Kentucky. About 12.7 days a year bring an inch or more (46th of 120), most often in February, out of 56.2 inches of total precipitation. On February 17, 2023, 2.78 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 4.91 inches (through March 1, 2021).
About 73 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
Roughly 41% of the county's housing was built before 1980. That puts Casey near the middle of Kentucky's 120 counties.
Older and newer homes sit side by side here: 15% predate 1960 and 25% are from 2000 or later. Corroded pipe is the typical failure in the first group, burst supply hoses in the second.
35% 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.
Here 23% of housing is manufactured homes. Check the skirting and the heat tape on the main water line every fall, because that one exposed line is what freezes.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 56 times a year here, close to the Kentucky county median of 59. 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 expectBy main heating fuel, Casey County homes break down as 6% utility gas, 73% electric, 5% propane and 14% wood. Wood heat is more common here than in most Kentucky counties. Heating equipment is one of the leading causes of home fires nationally, and the NFPA recommends having chimneys and vents inspected every year.
