With 21% of homes built before 1960 and about 23 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
Basements flood here mostly in September. Floyd County averages 11.6 days a year with an inch of rain or more.
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.
Floyd County's wettest day in the 2015–2024 record brought 3.7 inches, and about 90 freeze-thaw days a year mean ice dams in some winters.
29% of occupied homes in Floyd County heat mainly with wood or propane, above the Virginia county median of 11.9%.
Muggy summer nights, lows of 65°F or more, come about 10 times a year in Floyd County. Mold after a leak spreads fastest from June through August.
Local risk profile
With 7,977 homes and around 15,593 residents, Floyd County is 381 square miles of southern Virginia. Floyd is the county seat. Much of its housing is recent, with a median build year of 1987.
66/100 Water Damage Risk Index: Elevated Floyd County ranks 4 of 95 Virginia counties. See the statewide ranking and method.The three factors where Floyd County ranks highest compared with other Virginia counties.
Floyd County gets more hard-freeze nights than most of Virginia. In the 2015–2024 record the county logged about 23 nights a year at or below 20°F (11th of 95) and 99 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
The longest cold spell was straight 8 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about -7°F on December 24, 2022. Burst pipes usually show up when a spell like that breaks and the ice thaws.
The freeze season here runs November to March, 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 Oct 27 and end around Apr 18.
Heavy rain is a bigger factor here than in most of Virginia. The county gets about 51.7 inches of rain and melted snow a year, with 11.6 days of an inch or more (10th of 95). Those downpours cluster in April, September and October, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.7 inches on November 12, 2020. The worst three-day stretch dropped 6.08 inches, ending May 22, 2020, the kind of soaking that overwhelms sump pumps and storm sewers.
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 90 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
Virginia's 95 counties range widely in housing age; Floyd ranks 58th, with 41% of its homes built before 1980.
The mix runs from 21% built before 1960 to 29% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
About 31% 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 19% 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 10 nights a year in Floyd County stay at 65°F or warmer, a sign of muggy summer air (88th of 95 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 Floyd County's occupied homes: 1% utility gas, 64% electric, 9% propane and 20% wood. Wood heat is more common here than in most Virginia counties. Heating equipment is one of the leading causes of home fires nationally, and the NFPA recommends having chimneys and vents inspected every year.
