Local risk profile
Kendall County covers 662 square miles of central Texas, with about 48,567 residents and 19,213 homes. Boerne is the county seat; Comfort is the next largest community. Much of its housing is recent, with a median build year of 2002.
35/100 Water Damage Risk Index: Moderate Kendall County ranks 210 of 232 Texas counties. See the statewide ranking and method.The three factors where Kendall County ranks highest compared with other Texas counties.
For frozen pipes, Kendall County is a typical Texas county, which is still plenty. It averaged 21 freezing nights a year over 2015–2024, 2 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 126th.
Cold snaps are the real risk. The worst in the record lasted 5 days below freezing (ending February 2021), and the low bottomed out near 6°F on February 16, 2021.
With only about 21 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 6°F, on February 16, 2021.
Rainfall is about average for Texas. About 7.1 days a year bring an inch or more (127th of 232), most often in May, out of 29.2 inches of total precipitation. On May 24, 2015, 4.4 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 4.99 inches (through May 24, 2015).
Housing
17% of homes in Kendall County predate 1980, below the Texas county median of 45.8%, which ranks 222nd of Texas's 232 counties.
Since 2000 the county has added enough housing that 56% of homes are that new. Modern PEX and copper rarely fail on their own; the leaks come from connections, appliances and storms.
27% 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
Summer nights that don't drop below 65°F, a good marker of humid air, come about 139 times a year here, close to the Texas county median of 129. 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, Kendall County homes break down as 14% utility gas, 74% electric, 11% propane and under 1% wood. Propane heat is more common here than in most Texas counties. Heating equipment is one of the leading causes of home fires nationally, and the NFPA recommends having chimneys and vents inspected every year.
