Local risk profile
About 81,013 people live in James City County, 142 square miles in southeast Virginia, in roughly 34,726 homes. The county seat is Williamsburg. Much of its housing is recent, with a median build year of 1997.
34/100 Water Damage Risk Index: Moderate James City County ranks 89 of 95 Virginia counties. See the statewide ranking and method.The three factors where James City County ranks highest compared with other Virginia counties.
Winters here are on the gentler end for Virginia, and pipes still freeze. In the 2015–2024 record the county logged about 6 nights a year at or below 20°F (87th of 95) and 55 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
On January 6, 2018 the low fell to about 2°F, and in the stretch ending January 2018 the county went 3 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from December 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 Nov 17 and end around Mar 24.
Heavy rain is a bigger factor here than in most of Virginia. About 10.8 days a year bring an inch or more (29th of 95), most often in June, out of 51.4 inches of total precipitation. On October 9, 2016, 4.36 inches fell in a single day. The worst three-day stretch dropped 4.88 inches, ending July 24, 2018, the kind of soaking that overwhelms sump pumps and storm sewers.
About 54 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
18% of homes in James City County predate 1980, below the Virginia county median of 46.2%, which ranks 93rd of Virginia's 95 counties.
Since 2000 the county has added enough housing that 44% of homes are that new. Modern PEX and copper rarely fail on their own; the leaks come from connections, appliances and storms.
The 1980s and 1990s account for 38% 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.
Beyond water
James City County averages 101 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in July. 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 expectMain heating fuel in James City County's occupied homes: 46% utility gas, 50% electric, 2% propane and under 1% wood.
