With 35% of homes built before 1960 and about 5 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
September brings the most downpours to Northampton County, part of 9.1 heavy-rain days a year. Check the sump first.
Backups often follow heavy rain, which Northampton County gets about 9.1 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Northampton County, 5.07 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
18% of occupied homes in Northampton County heat mainly with wood or propane, above the Virginia county median of 11.9%.
About 105 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
Northampton County covers 212 square miles of southeast Virginia, with about 12,059 residents and 7,550 homes. The county seat is Eastville, and Exmore, Cape Charles and Nassawadox round out the largest towns. Half the homes here were built before 1982, half after.
53/100 Water Damage Risk Index: Elevated Northampton County ranks 40 of 95 Virginia counties. See the statewide ranking and method.The three factors where Northampton 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 5 nights a year at or below 20°F (93rd of 95) and 46 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
The longest cold spell was straight 4 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about 6°F on February 21, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
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.
Freezing nights typically start around Nov 24 and end around Mar 18.
Rainfall is about average for Virginia. The county gets about 47.4 inches of rain and melted snow a year, with 9.1 days of an inch or more (60th of 95). Those downpours cluster in September, October and December, when sump pumps and gutters are tested hardest. The wettest day on record brought 5.07 inches on October 9, 2016. The worst three-day stretch dropped 6.72 inches, ending October 10, 2016, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 43 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
Virginia's 95 counties range widely in housing age; Northampton ranks 36th, with 49% of its homes built before 1980.
Before 1960 is when 35% of these homes went up. Galvanized supply lines and cast iron drains were standard then, and after 60-plus years both corrode and crack, often out of sight inside a wall or under a slab.
Here 14% of housing is manufactured homes. Check the skirting and the heat tape on the main water line every fall, because that one exposed line is what freezes.
28% of homes were vacant at survey time. A leak in an empty rental or seasonal house can run for days before anyone notices, which is why those losses tend to be larger.
Renters occupy 34% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
Northampton County averages 105 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in July. 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 expectBy main heating fuel, Northampton County homes break down as 1% utility gas, 70% electric, 17% propane and under 1% wood. Propane 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.
