With 13% of homes built before 1960 and about 4 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
April brings the most downpours to Lee County, part of 9 heavy-rain days a year. Check the sump first.
13% 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.
Lee County's wettest day in the 2015–2024 record brought 4.12 inches, and about 49 freeze-thaw days a year mean ice dams in some winters.
8% of occupied homes in Lee County heat mainly with wood or propane, below the North Carolina county median of 11.7%.
About 96 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
Lee County covers 255 square miles of central North Carolina, with about 65,816 residents and 27,166 homes. Sanford is the county seat; Broadway is the next largest community. Much of its housing is recent, with a median build year of 1988.
29/100 Water Damage Risk Index: Moderate Lee County ranks 95 of 100 North Carolina counties. See the statewide ranking and method.The three factors where Lee County ranks highest compared with other North Carolina counties.
Pipe-freeze risk in Lee County sits near the middle of the state. From 2015–2024 it averaged 4 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 50 nights at or below 32°F. That ranks 58th of 100 counties.
The longest cold spell was straight 3 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about 6°F on January 7, 2018. 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 15 and end around Mar 23.
Lee gets fewer downpours than most North Carolina counties, but they still fill basements. About 9 days a year bring an inch or more (98th of 100), most often in April, out of 48.5 inches of total precipitation. On September 17, 2018, 4.12 inches fell in a single day. The worst three-day stretch dropped 10.39 inches, ending September 17, 2018, the kind of soaking that overwhelms sump pumps and storm sewers.
About 49 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; Lee ranks 60th, with 37% of its homes built before 1980.
Since 2000 the county has added enough housing that 31% of homes are that new. Modern PEX and copper rarely fail on their own; the leaks come from connections, appliances and storms.
About 32% 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.
Manufactured and mobile homes make up 15% 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
About 96 nights a year in Lee County stay at 65°F or warmer, a sign of muggy summer air (38th of 100 counties). September is the wettest month. The EPA recommends keeping indoor humidity below 60%, ideally 30 to 50%. Basements can pass 60% on their own in summer, so a dehumidifier matters even without a leak, and anything wet should be dried within 24 to 48 hours.
Mold remediation: what to expectMain heating fuel in Lee County's occupied homes: 13% utility gas, 78% electric, 7% propane and under 1% 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.
