Pipes freeze in Ohio County on about 29 nights a year, mostly November to March. Older homes, 55% of the stock here, are most at risk.
Basements flood here mostly in September. Ohio County averages 5.7 days a year with an inch of rain or more.
Sewage backups in Ohio County spike on heavy-rain days, about 5.7 a year, when sewer mains fill up and water finds the lowest drain.
Ohio County's wettest day in the 2015–2024 record brought 3.74 inches, and about 90 freeze-thaw days a year mean ice dams in some winters.
5% of occupied homes in Ohio County heat mainly with wood or propane, below the West Virginia county median of 10.1%.
About 26 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 21,120 homes and around 41,582 residents, Ohio County is 106 square miles of northern West Virginia. Besides Wheeling, the county seat, the biggest communities are Bethlehem, West Liberty and Triadelphia. It has some of the oldest housing in the state: the median home went up in 1956.
65/100 Water Damage Risk Index: Elevated Ohio County ranks 7 of 55 West Virginia counties. See the statewide ranking and method.The three factors where Ohio County ranks highest compared with other West Virginia counties.
Ohio is on the colder side of West Virginia for pipes. From 2015–2024 it averaged 29 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 111 nights at or below 32°F. That ranks 11th of 55 counties.
On February 20, 2015 the low fell to about -8°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.
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.
On average the first fall freeze arrives around Oct 29 and the last spring freeze around Apr 28.
Ohio gets fewer downpours than most West Virginia counties, but they still fill basements. The county gets about 45.6 inches of rain and melted snow a year, with 5.7 days of an inch or more (47th of 55). Those downpours cluster in June, July and September, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.74 inches on September 10, 2018. Multi-day storms matter most for basements; the wettest three days on record here totaled 6.12 inches (through September 11, 2018).
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
77% of homes in Ohio County predate 1980, above the West Virginia county median of 55.1%, which ranks 2nd of West Virginia's 55 counties.
Before 1960 is when 55% 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.
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
About 26 nights a year in Ohio County stay at 65°F or warmer, a sign of muggy summer air (29th of 55 counties). June is the wettest month. 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 expectBy main heating fuel, Ohio County homes break down as 65% utility gas, 28% electric, 3% propane and 2% wood. Most homes here heat with gas or electricity, so cooking and electrical faults are the likelier fire sources. Even a contained kitchen fire can send soot through the ductwork to every room.
