Abbeville County averages 2 nights a year at 20°F or colder, mostly January, and 24% of its homes predate 1960.
December brings the most downpours to Abbeville County, part of 12.6 heavy-rain days a year. Check the sump first.
Backups often follow heavy rain, which Abbeville County gets about 12.6 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
In Abbeville County, 4.73 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
8% of occupied homes in Abbeville County heat mainly with wood or propane, above the South Carolina county median of 5.1%.
About 106 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
About 24,420 people live in Abbeville County, 491 square miles in northwest South Carolina, in roughly 11,806 homes. The county seat is Abbeville, and Calhoun Falls, Lake Secession and Due West round out the largest towns. Half the homes here were built before 1980, half after.
59/100 Water Damage Risk Index: Elevated Abbeville County ranks 12 of 46 South Carolina counties. See the statewide ranking and method.The three factors where Abbeville County ranks highest compared with other South Carolina counties.
Pipe-freeze risk in Abbeville County sits near the middle of the state. From 2015–2024 it averaged 2 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 40 nights at or below 32°F. That ranks 20th of 46 counties.
The freeze season here runs January, 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 Nov 19 and end around Mar 18.
Heavy rain is a bigger factor here than in most of South Carolina. About 12.6 days a year bring an inch or more (14th of 46), most often in December, out of 49.5 inches of total precipitation. On October 4, 2015, 4.73 inches fell in a single day. The worst three-day stretch dropped 6.04 inches, ending October 4, 2015, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 40 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 50% of the county's housing was built before 1980. That puts Abbeville among the oldest housing stocks of South Carolina's 46 counties.
Before 1960 is when 24% 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.
33% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
24% of homes are manufactured or mobile homes, close to the South Carolina county median of 22%. 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.
Beyond water
About 106 nights a year in Abbeville County stay at 65°F or warmer, a sign of muggy summer air (29th of 46 counties). December 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 expectHeating fuel matters for fire risk. In Abbeville County it's 22% utility gas, 68% electric, 6% propane and 2% wood. Wood heat is more common here than in most South Carolina counties. Heating equipment is one of the leading causes of home fires nationally, and the NFPA recommends having chimneys and vents inspected every year.
