With 23% of homes built before 1960 and about 44 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
Heavy rain days of an inch or more come about 8.3 times a year here, most often in April. A sump pump that hasn't run since last season is a common weak point.
Backups often follow heavy rain, which Pocahontas County gets about 8.3 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Pocahontas County, 3.04 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
50% of occupied homes in Pocahontas County heat mainly with wood or propane, above the West Virginia county median of 10.1%.
About 0 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 6,834 homes and around 7,784 residents, Pocahontas County is 940 square miles of southern West Virginia. Marlinton is the county seat; Durbin, Hillsboro and Frank are the next largest communities. Half the homes here were built before 1982, half after.
61/100 Water Damage Risk Index: Elevated Pocahontas County ranks 13 of 55 West Virginia counties. See the statewide ranking and method.The three factors where Pocahontas County ranks highest compared with other West Virginia counties.
Pocahontas County gets more hard-freeze nights than most of West Virginia. From 2015–2024 it averaged 44 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 130 nights at or below 32°F. That ranks 1st of 55 counties.
On December 24, 2022 the low fell to about -11°F, and in the stretch ending January 2018 the county went 14 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.
Freezing nights typically start around Oct 18 and end around May 5.
Heavy rain is a bigger factor here than in most of West Virginia. Of roughly 51.5 inches of yearly precipitation, the damage comes from the 8.3 days a year with an inch or more, ranked 4th of 55. April, June and September see the most. The single wettest day in the record: 3.04 inches, September 30, 2016. The worst three-day stretch dropped 4.81 inches, ending June 24, 2016, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 100 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
Roughly 45% of the county's housing was built before 1980. That puts Pocahontas among the newer housing stocks of West Virginia's 55 counties.
22% of homes were built in 2000 or later, more than in most of West Virginia. Newer plumbing rarely corrodes, so damage here tends to come from appliance supply lines, water heaters, sump pumps and storms.
About 33% 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.
14% of homes are manufactured or mobile homes, close to the West Virginia county median of 16.2%. 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 54% of homes as vacant, above the West Virginia county median of 17.4%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 0 times a year here, below the West Virginia county median of 27. 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 Pocahontas County it's 3% utility gas, 37% electric, 25% propane and 25% wood. Wood and propane heat are 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.
