Seguin, the Guadalupe County seat, sits at about 558 feet with the Guadalupe River running along its southern edge and spring-fed Walnut Branch flowing through town to meet it. Many streets hold homes from the late 1800s and the first half of the twentieth century, and about 20 of the city's nineteenth-century concrete buildings still stand.

The Guadalupe River, Walnut Branch and a decade of declarations
The Guadalupe River flooded in 2002 after the region received more than 19 inches of rain, and Guadalupe County was included in a FEMA severe storms and flooding declaration that year. Since then the county has been named in federal declarations for severe storms and flooding in 2007, 2015 (twice), 2024 and 2025, plus Hurricane Harvey in 2017.
Seguin's summers are very hot and humid from June into September, and October tends to be rainy. Winters are usually mild, but strong northers can drop temperatures 30 degrees or more in a day. Guadalupe County was part of the 2021 Severe Winter Storms declaration when much of Texas froze.
Leaks, freezes and water damage restoration in Seguin
Older houses near the historic core may have aging plumbing and original wood floors, while newer homes on slabs are more likely to see slab leaks and attic line failures. Across the board, AC condensate overflows in humid summers, water heater leaks and burst pipes during sudden cold snaps are common calls.
Water damage restoration in Seguin starts with stopping the water, extracting it and measuring how far moisture has spread, then drying the structure with dehumidifiers and air movers. Rebuilding finishes the job as water damage repair. Learn more on water damage restoration and burst pipe water damage.

Fire, soot and odor in older buildings
Cold-weather fires have shaped local history: Guadalupe College's main buildings burned in 1936 after a boiler malfunctioned on a bitterly cold night. Today, heating equipment during northers, cooking and electrical problems remain leading causes of house fires.
Restoration contractors typically secure the structure, remove debris, test soot, clean from the top down and deodorize, paying attention to porous surfaces such as old plaster and wood trim. See fire damage restoration and soot removal for the steps involved.
River flooding and storm cleanup
When the Guadalupe or local creeks rise, floodwater that enters a house carries mud, debris and sewage. Contractors generally remove soaked carpet, padding and lower drywall, clean and disinfect the framing, and dry everything before rebuilding.
Severe storms and tornadoes add roof and window damage, so tarping and board-up are often first. What a Guadalupe River flood or wind job usually involves is laid out under flood damage restoration and storm damage cleanup.
Humidity and mold near the river
Hot, humid summers and wet Octobers give mold plenty of chances to grow on materials that stay damp. Crawl spaces, closets on exterior walls and areas around AC air handlers are frequent problem spots.
The EPA says homeowners can usually clean mold under roughly 10 square feet after fixing the moisture source. Larger areas or growth after river flooding should go to professional mold remediation with containment.
Seguin safety checklist before cleanup
- Call 911 for fire, injuries, gas odors or downed lines.
- Follow city and Guadalupe County instructions during flood warnings, and check the City of Seguin website for updates.
- Never drive through flooded crossings or approach a swollen river.
- Close the main water valve for plumbing leaks and cut power to wet areas only if it is safe.
- Before tearing anything out, snap photos of every wet room and keep a folder of receipts.
- Flood damage often requires separate coverage; confirm with your insurer or agent.

Seguin restoration FAQs
How often has Guadalupe County had flood disasters?
Guadalupe County has been included in FEMA declarations involving flooding in 2002, 2007, 2015, 2024 and 2025, as well as Hurricane Harvey in 2017. River and creek flooding is a recurring risk.
What month is typically rainiest in Seguin?
October is usually a rainy month in Seguin, and heavy storms can occur in spring as well. Clearing gutters and checking drainage before fall is a good habit.
Can sudden cold fronts damage pipes in Seguin?
Yes. Northers can drop temperatures 30 degrees or more in a day, catching unprotected pipes off guard. The 2021 winter storm declaration covered Guadalupe County, and burst pipes were widespread.
My home is over 100 years old. Does that change how water damage is handled?
It can. Original plaster, hardwood and trim may be worth drying in place rather than replacing. Ask contractors how they handle older materials and whether they will provide moisture readings.
Does Fire & Water Energy send its own crew to Seguin?
No. We are a referral service only. Call (866) 937-3230 and we'll try to connect you with an independent contractor serving Seguin, based on local availability.
