53% 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.
Jefferson County's wettest day in the 2015–2024 record brought 3.37 inches, and about 84 freeze-thaw days a year mean ice dams in some winters.
9% of occupied homes in Jefferson County heat mainly with wood or propane, below the Ohio county median of 15.9%.
With 26 muggy nights a year, mold in Jefferson County can appear within days of a leak. Dry first, then clean.
Local risk profile
With 31,025 homes and around 64,518 residents, Jefferson County is 408 square miles of eastern Ohio. Besides Steubenville, the county seat, the biggest communities are Toronto, Wintersville and Mingo Junction. It has some of the oldest housing in the state: the median home went up in 1958.
54/100 Water Damage Risk Index: Elevated Jefferson County ranks 35 of 88 Ohio counties. See the statewide ranking and method.The three factors where Jefferson County ranks highest compared with other Ohio counties.
Pipe-freeze risk in Jefferson County sits near the middle of the state. It averaged 108 freezing nights a year over 2015–2024, 30 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 88 Ohio counties that's 49th.
The longest cold spell was straight 13 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about -8°F on February 20, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
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 Nov 1 and end around Apr 24.
Rainfall is about average for Ohio. The county gets about 43.8 inches of rain and melted snow a year, with 5.5 days of an inch or more (51st of 88). Those downpours cluster in June, August and September, when sump pumps and gutters are tested hardest. The wettest day on record brought 3.37 inches on September 10, 2018. The worst three-day stretch dropped 5.18 inches, ending September 10, 2018, the kind of soaking that overwhelms sump pumps and storm sewers.
About 84 days a year swing from below freezing at night to above freezing by day. Those freeze-thaw cycles feed ice dams on roofs, open cracks in foundations and driveways, and stress pipes that are already marginal.
Housing
80% of homes in Jefferson County predate 1980, above the Ohio county median of 61.1%, which ranks 2nd of Ohio's 88 counties.
In Jefferson County 53% 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.
With 13% of homes empty at survey time, landlords and seasonal owners should shut off the main or schedule checks in winter. An unheated vacant house is also where many policies limit freeze coverage.
Beyond water
Jefferson County averages 26 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in June. 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 expectHeating fuel matters for fire risk. In Jefferson County it's 50% utility gas, 28% electric, 6% 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.
