With 31% of homes built before 1960 and about 13 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
May brings the most downpours to Caddo County, part of 9 heavy-rain days a year. Check the sump first.
31% 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 Caddo County, 3.8 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
12% of occupied homes in Caddo County heat mainly with wood or propane, close to the Oklahoma county median of 12.5%.
Muggy summer nights, lows of 65°F or more, come about 100 times a year in Caddo County. Mold after a leak spreads fastest from June through August.
Local risk profile
With 11,545 homes and around 26,447 residents, Caddo County is 1,278 square miles of central Oklahoma. Besides Anadarko, the county seat, the biggest communities are Hinton, Carnegie and Hydro. The county's median home was built in 1972.
51/100 Water Damage Risk Index: Elevated Caddo County ranks 32 of 77 Oklahoma counties. See the statewide ranking and method.The three factors where Caddo County ranks highest compared with other Oklahoma counties.
For frozen pipes, Caddo County is a typical Oklahoma county, which is still plenty. It averaged 69 freezing nights a year over 2015–2024, 13 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 77 Oklahoma counties that's 38th.
On February 17, 2021 the low fell to about -9°F, and in the stretch ending February 2021 the county went 11 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from December to February, 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.
On average the first fall freeze arrives around Nov 6 and the last spring freeze around Mar 30.
Caddo gets fewer downpours than most Oklahoma counties, but they still fill basements. About 9 days a year bring an inch or more (54th of 77), most often in May, out of 33.5 inches of total precipitation. On May 24, 2015, 3.8 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 4.77 inches (through November 5, 2024).
The temperature crosses 32°F in both directions on roughly 63 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
67% of homes in Caddo County predate 1980, above the Oklahoma county median of 54.8%, which ranks 18th of Oklahoma's 77 counties.
31% were built before 1960. Homes from that era often still have galvanized steel supply pipe, which rusts from the inside until it pinholes, and cast iron drains that crack with age. Slow leaks behind walls are a common start to water damage in these houses.
12% of homes are manufactured or mobile homes, close to the Oklahoma county median of 12.3%. 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.
With 22% 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
Summer nights that don't drop below 65°F, a good marker of humid air, come about 100 times a year here, close to the Oklahoma county median of 98. 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 expectBy main heating fuel, Caddo County homes break down as 39% utility gas, 48% electric, 11% propane and 2% 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.
