Local risk profile
With 59,197 homes and around 152,852 residents, Coweta County is 441 square miles of western Georgia. The county seat is Newnan, and Senoia, Grantville and East Newnan round out the largest towns. Much of its housing is recent, with a median build year of 1999.
52/100 Water Damage Risk Index: Elevated Coweta County ranks 68 of 159 Georgia counties. See the statewide ranking and method.The three factors where Coweta County ranks highest compared with other Georgia counties.
Coweta is on the colder side of Georgia for pipes. It averaged 39 freezing nights a year over 2015–2024, 3 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 159 Georgia counties that's 25th.
Expect the hardest freezes in January, inside a season that runs January. That's when an outdoor spigot left connected to a hose, or a pipe in a crawl space, is most likely to split.
On average the first fall freeze arrives around Nov 17 and the last spring freeze around Mar 15.
Heavy rain is a bigger factor here than in most of Georgia. Of roughly 56.4 inches of yearly precipitation, the damage comes from the 13.1 days a year with an inch or more, ranked 41st of 159. January, April and December see the most. The single wettest day in the record: 5.57 inches, September 27, 2024. Multi-day storms matter most for basements; the wettest three days on record here totaled 8.18 inches (through September 28, 2024).
The temperature crosses 32°F in both directions on roughly 39 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 20% of the county's housing was built before 1980. That puts Coweta among the newer housing stocks of Georgia's 159 counties.
Since 2000 the county has added enough housing that 47% of homes are that new. Modern PEX and copper rarely fail on their own; the leaks come from connections, appliances and storms.
34% 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.
Beyond water
Coweta County averages 102 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in January. 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 Coweta County it's 43% utility gas, 51% electric, 5% propane and under 1% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
