Pipes freeze in Tazewell County on about 26 nights a year, mostly November to March. Older homes, 31% of the stock here, are most at risk.
February brings the most downpours to Tazewell County, part of 7.6 heavy-rain days a year. Check the sump first.
31% 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.
Tazewell County's wettest day in the 2015–2024 record brought 3.9 inches, and about 93 freeze-thaw days a year mean ice dams in some winters.
9% of occupied homes in Tazewell County heat mainly with wood or propane, below the Virginia county median of 11.9%.
About 4 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
With 19,768 homes and around 39,624 residents, Tazewell County is 519 square miles of southwest Virginia. Tazewell is the county seat; Richlands, Bluefield and Claypool Hill are the next largest communities. Half the homes here were built before 1975, half after.
58/100 Water Damage Risk Index: Elevated Tazewell County ranks 26 of 95 Virginia counties. See the statewide ranking and method.The three factors where Tazewell County ranks highest compared with other Virginia counties.
Tazewell County gets more hard-freeze nights than most of Virginia. It averaged 107 freezing nights a year over 2015–2024, 26 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 95 Virginia counties that's 3rd.
Cold snaps are the real risk. The worst in the record lasted 13 days below freezing (ending January 2018), and the low bottomed out near -10°F on February 20, 2015.
Most freezing nights fall from November to March, 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 Oct 20 and end around Apr 25.
Tazewell gets fewer downpours than most Virginia counties, but they still fill basements. The county gets about 49.8 inches of rain and melted snow a year, with 7.6 days of an inch or more (86th of 95). Those downpours cluster in February, April and May, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.9 inches on September 26, 2024. The worst three-day stretch dropped 7.43 inches, ending September 28, 2024, the kind of soaking that overwhelms sump pumps and storm sewers.
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 93 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
Roughly 60% of the county's housing was built before 1980. That puts Tazewell among the oldest housing stocks of Virginia's 95 counties.
In Tazewell County 31% of homes are older than 1960. If yours is one of them and the plumbing has never been replaced, expect galvanized steel supply pipe and cast iron drain lines, the two materials most likely to fail quietly.
About 27% 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.
22% of homes are manufactured or mobile homes, above the Virginia county median of 9.6%. 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.
The Census counted 18% of homes as vacant, above the Virginia county median of 15%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
Beyond water
Tazewell County averages 4 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in May. 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 Tazewell County's occupied homes: 6% utility gas, 80% electric, 7% propane and 3% wood. Fires here are likelier to start in the kitchen or the wiring than in the furnace. After any fire, keep the HVAC off until ducts are checked, or soot will travel through the house.
