Local risk profile
About 269,294 people live in Webb County, 3,361 square miles in southern Texas, in roughly 88,176 homes. The county seat is Laredo, and Rio Bravo, El Cenizo and Los Altos round out the largest towns. Much of its housing is recent, with a median build year of 1997.
27/100 Water Damage Risk Index: Moderate Webb County ranks 228 of 232 Texas counties. See the statewide ranking and method.The three factors where Webb County ranks highest compared with other Texas counties.
Winters here are on the gentler end for Texas, and pipes still freeze. From 2015–2024 it averaged 0 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 5 nights at or below 32°F. That ranks 205th of 232 counties.
Hard freezes are uncommon here, about 5 nights a year at or below 32°F, and that's exactly why they do damage: pipes in attics, exterior walls and slab-edge plumbing are rarely insulated. The coldest night in the record was about 17°F on February 16, 2021.
Webb gets fewer downpours than most Texas counties, but they still fill basements. The county gets about 21.1 inches of rain and melted snow a year, with 5.3 days of an inch or more (165th of 232). Those downpours cluster in May, August and September, when sump pumps and gutters are tested hardest. The wettest day on record brought 4.13 inches on August 15, 2022. The worst three-day stretch dropped 8.63 inches, ending September 28, 2017, the kind of soaking that overwhelms sump pumps and storm sewers.
Housing
24% of homes in Webb County predate 1980, below the Texas county median of 45.8%, which ranks 208th of Texas's 232 counties.
43% of homes were built in 2000 or later, more than in most of Texas. 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 33% 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 8% 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.
Renters occupy 35% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
Webb County averages 187 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in September. 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 Webb County it's 12% utility gas, 85% electric, under 1% propane and under 1% wood. Most homes here heat with gas or electricity, so cooking and electrical faults are the likelier fire sources. Even a contained kitchen fire can send soot through the ductwork to every room.
