Jones County averages 3 nights a year at 20°F or colder, mostly January, and 21% of its homes predate 1960.
Heavy rain days of an inch or more come about 13.2 times a year here, most often in July. A sump pump that hasn't run since last season is a common weak point.
21% 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 Jones County, 7.76 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
14% of occupied homes in Jones County heat mainly with wood or propane, above the North Carolina county median of 11.7%.
About 101 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
Jones County covers 471 square miles of eastern North Carolina, with about 9,302 residents and 4,698 homes. Besides Trenton, the county seat, the biggest communities are Maysville and Pollocksville. Much of its housing is recent, with a median build year of 1988.
55/100 Water Damage Risk Index: Elevated Jones County ranks 42 of 100 North Carolina counties. See the statewide ranking and method.The three factors where Jones County ranks highest compared with other North Carolina counties.
Jones County is milder than most of North Carolina, but not mild enough to skip winterizing. It averaged 44 freezing nights a year over 2015–2024, 3 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 100 North Carolina counties that's 74th.
The freeze season here runs January, 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 15 and the last spring freeze around Mar 21.
Heavy rain is a bigger factor here than in most of North Carolina. The county gets about 57.6 inches of rain and melted snow a year, with 13.2 days of an inch or more (28th of 100). Those downpours cluster in July, August and September, when sump pumps and gutters are tested hardest. The wettest day on record brought 7.76 inches on September 15, 2018. Multi-day storms matter most for basements; the wettest three days on record here totaled 15.06 inches (through September 16, 2018).
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 43 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
North Carolina's 100 counties range widely in housing age; Jones ranks 46th, with 42% of its homes built before 1980.
Growth since 2000 added 32% of today's homes. In houses that new, the weak points are washing machine hoses, ice maker lines, water heaters and sump pumps rather than the pipes in the walls.
About 26% 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.
31% 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
Jones County averages 101 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in September. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectBy main heating fuel, Jones County homes break down as 6% utility gas, 79% electric, 12% propane and 2% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
