Wilkes County averages 10 nights a year at 20°F or colder, mostly December to February, and 20% of its homes predate 1960.
Heavy rain days of an inch or more come about 14.2 times a year here, most often in October. A sump pump that hasn't run since last season is a common weak point.
20% 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 Wilkes County, 5.2 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
16% of occupied homes in Wilkes County heat mainly with wood or propane, above the North Carolina county median of 11.7%.
About 51 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
Wilkes County covers 754 square miles of northern North Carolina, with about 65,935 residents and 31,836 homes. Besides Wilkesboro, the county seat, the biggest communities are North Wilkesboro, Cricket and Mulberry. The county's median home was built in 1980.
66/100 Water Damage Risk Index: Elevated Wilkes County ranks 10 of 100 North Carolina counties. See the statewide ranking and method.The three factors where Wilkes County ranks highest compared with other North Carolina counties.
Wilkes is on the colder side of North Carolina for pipes. 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 75 nights at or below 32°F. That ranks 19th of 100 counties.
Cold snaps are the real risk. The worst in the record lasted 5 days below freezing (ending January 2018), and the low bottomed out near 1°F on February 20, 2015.
The freeze season here runs December to February, with January the coldest. If you travel then, leave the thermostat at 55°F or above and open sink cabinets on outside walls.
On average the first fall freeze arrives around Nov 4 and the last spring freeze around Apr 11.
Heavy rain is a bigger factor here than in most of North Carolina. About 14.2 days a year bring an inch or more (19th of 100), most often in October, out of 56.4 inches of total precipitation. On September 27, 2024, 5.2 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 8.93 inches (through September 28, 2024).
About 71 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
North Carolina's 100 counties range widely in housing age; Wilkes ranks 14th, with 51% of its homes built before 1980.
Housing age is mixed: 20% of homes are pre-1960 and 17% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
About 33% of homes went up between 1980 and 1999. Some houses from the late 1970s to the mid-1990s were plumbed with polybutylene, a gray plastic pipe known for failing at fittings. A plumber can tell you in a few minutes whether you have it.
25% of homes are manufactured or mobile homes, above the North Carolina county median of 17.4%. 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
Summer nights that don't drop below 65°F, a good marker of humid air, come about 51 times a year here, below the North Carolina county median of 88.5. 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, Wilkes County homes break down as 2% utility gas, 74% electric, 10% propane and 6% wood. Wood heat is more common here than the state median. Have chimneys swept and fuel-burning appliances serviced each fall, and keep three feet clear around stoves and space heaters.
