Pipes freeze in Wyoming County on about 22 nights a year, mostly November to March. Older homes, 35% of the stock here, are most at risk.
Basements flood here mostly in February. Wyoming County averages 6.6 days a year with an inch of rain or more.
35% 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.
Wyoming County's wettest day in the 2015–2024 record brought 2.83 inches, and about 88 freeze-thaw days a year mean ice dams in some winters.
9% of occupied homes in Wyoming County heat mainly with wood or propane, below the West Virginia county median of 10.1%.
With 23 muggy nights a year, mold in Wyoming County can appear within days of a leak. Dry first, then clean.
Local risk profile
About 20,629 people live in Wyoming County, 499 square miles in southwest West Virginia, in roughly 9,953 homes. Besides Pineville, the county seat, the biggest communities are Mullens, Oceana and Corinne. Half the homes here were built before 1974, half after.
41/100 Water Damage Risk Index: Moderate Wyoming County ranks 43 of 55 West Virginia counties. See the statewide ranking and method.The three factors where Wyoming County ranks highest compared with other West Virginia counties.
Winters here are on the gentler end for West Virginia, and pipes still freeze. From 2015–2024 it averaged 22 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 99 nights at or below 32°F. That ranks 42nd of 55 counties.
On February 20, 2015 the low fell to about -12°F, and in the stretch ending January 2018 the county went 13 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Expect the hardest freezes in January, inside a season that runs November to March. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
Freezing nights typically start around Oct 28 and end around Apr 22.
Rainfall is about average for West Virginia. About 6.6 days a year bring an inch or more (34th of 55), most often in February, out of 49.1 inches of total precipitation. On February 17, 2023, 2.83 inches fell in a single day. The worst three-day stretch dropped 4.41 inches, ending July 28, 2022, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 88 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
West Virginia's 55 counties range widely in housing age; Wyoming ranks 13th, with 63% of its homes built before 1980.
35% were built before 1960. Homes from that era often still have galvanized steel supply pipe, which rusts from the inside until it pinholes, and cast iron drains that crack with age. Slow leaks behind walls are a common start to water damage in these houses.
The 1980s and 1990s account for 24% 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.
Manufactured and mobile homes make up 25% 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
Wyoming County averages 23 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, Wyoming County homes break down as 27% utility gas, 63% electric, 3% propane and 6% wood. Wood heat is more common here than in most West 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.
