January brings the most downpours to Oglethorpe County, part of 13.9 heavy-rain days a year. Check the sump first.
13% 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.
In Oglethorpe County, 4.7 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
18% of occupied homes in Oglethorpe County heat mainly with wood or propane, above the Georgia county median of 7.1%.
Muggy summer nights, lows of 65°F or more, come about 99 times a year in Oglethorpe County. Mold after a leak spreads fastest from June through August.
Local risk profile
With 6,511 homes and around 15,509 residents, Oglethorpe County is 439 square miles of northern Georgia. Besides Lexington, the county seat, the biggest communities are Crawford, Arnoldsville and Maxeys. Much of its housing is recent, with a median build year of 1990.
54/100 Water Damage Risk Index: Elevated Oglethorpe County ranks 62 of 159 Georgia counties. See the statewide ranking and method.The three factors where Oglethorpe County ranks highest compared with other Georgia counties.
Oglethorpe is on the colder side of Georgia for pipes. In the 2015–2024 record the county logged about 2 nights a year at or below 20°F (48th of 159) and 42 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
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.
On average the first fall freeze arrives around Nov 17 and the last spring freeze around Mar 19.
Heavy rain is a bigger factor here than in most of Georgia. The county gets about 51.2 inches of rain and melted snow a year, with 13.9 days of an inch or more (24th of 159). Those downpours cluster in January, April and December, when sump pumps and gutters are tested hardest. The wettest day on record brought 4.7 inches on September 27, 2024. Multi-day storms matter most for basements; the wettest three days on record here totaled 6.82 inches (through September 27, 2024).
The temperature crosses 32°F in both directions on roughly 42 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
Georgia's 159 counties range widely in housing age; Oglethorpe ranks 86th, with 37% of its homes built before 1980.
32% of homes were built in 2000 or later, more than in most of Georgia. Newer plumbing rarely corrodes, so damage here tends to come from appliance supply lines, water heaters, sump pumps and storms.
The 1980s and 1990s account for 31% 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.
17% of homes were vacant at survey time. A leak in an empty rental or seasonal house can run for days before anyone notices, which is why those losses tend to be larger.
Beyond water
About 99 nights a year in Oglethorpe County stay at 65°F or warmer, a sign of muggy summer air (121st of 159 counties). January 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 expectMain heating fuel in Oglethorpe County's occupied homes: 9% utility gas, 72% electric, 13% propane and 5% wood. Wood and propane heat are more common here than the state median. Have chimneys swept and fuel-burning appliances serviced each fall, and keep three feet clear around stoves and space heaters.
