With 15% of homes built before 1960 and about 17 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
February brings the most downpours to Perry County, part of 9.8 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.
Perry County's wettest day in the 2015–2024 record brought 4.47 inches, and about 78 freeze-thaw days a year mean ice dams in some winters.
8% of occupied homes in Perry County heat mainly with wood or propane, below the Kentucky county median of 12.6%.
About 45 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 27,499 people live in Perry County, 340 square miles in southeast Kentucky, in roughly 13,295 homes. The county seat is Hazard, and Diablock, Jeff and Vicco round out the largest towns. Much of its housing is recent, with a median build year of 1985.
25/100 Water Damage Risk Index: Moderate Perry County ranks 117 of 120 Kentucky counties. See the statewide ranking and method.The three factors where Perry County ranks highest compared with other Kentucky counties.
Winters here are on the gentler end for Kentucky, and pipes still freeze. From 2015–2024 it averaged 17 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 87 nights at or below 32°F. That ranks 86th of 120 counties.
Cold snaps are the real risk. The worst in the record lasted 7 days below freezing (ending January 2016), and the low bottomed out near -14°F on February 20, 2015.
Most freezing nights fall from November 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 16.
Perry gets fewer downpours than most Kentucky counties, but they still fill basements. The county gets about 52.5 inches of rain and melted snow a year, with 9.8 days of an inch or more (90th of 120). Those downpours cluster in February, July and December, when sump pumps and gutters are tested hardest. The wettest day on record brought 4.47 inches on July 28, 2022. The worst three-day stretch dropped 7.47 inches, ending July 29, 2022, the kind of soaking that overwhelms sump pumps and storm sewers.
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 78 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
42% of homes in Perry County predate 1980, close to the Kentucky county median of 44.1%, which ranks 71st of Kentucky's 120 counties.
Housing age is mixed: 15% of homes are pre-1960 and 24% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
The 1980s and 1990s account for 34% 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 32% 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.
With 17% of homes empty at survey time, landlords and seasonal owners should shut off the main or schedule checks in winter. An unheated vacant house is also where many policies limit freeze coverage.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 45 times a year here, below 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 expectMain heating fuel in Perry County's occupied homes: 15% utility gas, 74% 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.
