What's different about Seguin

The soil changes across the county. The Texas State Historical Association says the northwestern part of Guadalupe County, near the Comal and Hays county lines, is Blackland Prairie, and the rest lies in the Upper Coastal Plain. Soils run "from dark, calcareous clay in the northwest to fine, sandy loam in the southeast." Texas Parks and Wildlife describes Blackland soils as dark alkaline clays known as "black gumbo," the kind that swell when wet and shrink when dry. Seguin sits in the middle of the county, so two homes across town can sit on very different ground. Look up your own lot on USDA's Web Soil Survey.

It's an old town with old houses. TSHA says the townsite was laid out in 1838 as Walnut Springs and renamed Seguin in 1839, and the town was incorporated in 1853. Seguin's first schoolhouse was built in 1850 by John E. Park, inventor of "Park's concrete," and the state recognized it in 1962 as the oldest continuously used school building in Texas. An older house may sit on pier and beam rather than a slab, and the two are repaired differently, so find out which you have.

The city has its own contractor and permit rules. Seguin's permits page says that to construct, enlarge, alter or repair a building, an application must be made to the Building Official, and the contractor submits the permit application. It also says that if you hire out any phase of the work, the contractor must be licensed with the City of Seguin. The Permits Department is at 830-401-2435.

It's growing. Census Reporter counts about 33,800 residents and 13,397 housing units in Seguin (ACS 2024 5-year), with a median owner-occupied home value of $249,400. TSHA recorded about 22,000 residents in 2000.

What causes foundation trouble around Seguin

• Drought and rain cycles. Clay soils shrink as they dry and swell as they rewet, and the movement is rarely even under a whole house.
• Plumbing leaks. A leak under a slab wets the soil around it. The Texas Department of Insurance says most home policies cover sudden water damage, like a burst pipe, but not gradual leaks.
• Freezes. The National Weather Service recorded 3 inches of snow just south-southwest of Seguin on February 15, 2021, during the winter storm. Hard freezes break pipes, which brings plumbing back into the picture.
• Drainage. Downspouts that empty against the foundation and yards that slope toward the house keep soil wet on one side.

The number of piers your house needs drives most of the price. The foundation repair cost guide explains every factor and what insurance does and doesn't pay for.

Plan for the city permit in your timeline. Ask the company how long Seguin's permit and inspections usually add to the job.

Before you hire in Seguin

1. Ask whether the company is licensed with the City of Seguin, as the city requires for hired contractors.
2. Ask whether it submits the permit application to the Building Official.
3. Get the pier plan, depths and price in writing.
4. Ask whether it recommends a plumbing test before or after the lift.
5. Ask whether any warranty is transferable to a future buyer.
6. For a large job or an older home, consider an independent evaluation by a Texas-licensed professional engineer (P.E.).

Common questions

Do I need a permit for foundation repair in Seguin?

Seguin's permits page says an application must be made to the Building Official to construct, alter or repair a building, and that the contractor submits it. Ask the company whether it pulls the permit, or call the city's Permits Department at 830-401-2435.

The city's permits page says that if you hire out any phase of the building process, the contractor must be licensed with the City of Seguin. Ask whether the company is, before you sign.

Can I do foundation work on my own Seguin home?

The city allows homeowners who own and live in a home registered as their homestead with the Guadalupe County Appraisal District to pull permits for their own work. HomeAdvisor notes that even simple foundation repairs often require professional skills and tools, so DIY isn't the best option.
