Local risk profile

40/100 Water Damage Risk Index: Moderate Uvalde County ranks 192 of 232 Texas counties. See the statewide ranking and method.The three factors where Uvalde County ranks highest compared with other Texas counties.
Uvalde County is milder than most of Texas, but not mild enough to skip winterizing. It averaged 15 freezing nights a year over 2015–2024, 1 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 232 Texas counties that's 159th.
With only about 15 freezing nights a year, many homes here aren't built for cold, so a single arctic outbreak can burst pipes across the county. The record low in this data was about 12°F, on February 16, 2021.
Rainfall is about average for Texas. About 6.2 days a year bring an inch or more (142nd of 232), most often in May, out of 24.4 inches of total precipitation. On October 9, 2015, 2.41 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 4.56 inches (through December 5, 2016).
Housing
44% of homes in Uvalde County predate 1980, close to the Texas county median of 45.8%, which ranks 130th of Texas's 232 counties.
Housing age is mixed: 17% of homes are pre-1960 and 23% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
The 1980s and 1990s account for 32% 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.
Here 14% of housing is manufactured homes. Check the skirting and the heat tape on the main water line every fall, because that one exposed line is what freezes.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 156 times a year here, above the Texas county median of 129. Mold grows when indoor humidity stays above about 60%, the EPA's ceiling. A basement dehumidifier set to 50% and drying anything wet within 24 to 48 hours prevents most problems.
Mold remediation: what to expectHeating fuel matters for fire risk. In Uvalde County it's 13% utility gas, 77% electric, 7% propane and under 1% wood. Fires here are likelier to start in the kitchen or the wiring than in the furnace. After any fire, keep the HVAC off until ducts are checked, or soot will travel through the house.
