Plumber in Seguin, TX

Historic houses downtown, new ones at the edges

Seguin was founded in 1838, and its historic downtown district is on the National Register of Historic Places.

Older homes near downtown have usually been patched by several owners. What we check for there:

• Galvanized supply pipe rusting from the inside, so pressure drops and the water runs tinted (repiping).
• Cast-iron or clay sewer pipe with cracks or roots, found with a camera inspection before anyone digs.
• Supply lines in a crawl space under a raised floor, which feel a hard freeze long before pipes in a slab.

The city is growing quickly too: 29,433 people at the 2020 census and an estimated 41,048 in 2025. Newer houses mostly sit on slabs with plastic pipe, so the calls change: an original tank water heater wears out, a slab leak shows as a warm patch of tile, or grease closes off the kitchen line.

Seguin water, sewer and gas: who handles what

The City of Seguin owns and runs its own water, wastewater and electric systems. City water comes from two sources: Guadalupe River water treated at the city plant on River Drive West, and Carrizo Aquifer groundwater bought from the Schertz-Seguin Local Government Corporation.

Some outlying areas get water from Springs Hill Special Utility District or other rural systems. In January 2026, roughly 9,500 acres north of I-10, between State Highway 46 and State Highway 123, moved from Springs Hill to city water service.

Natural gas is not a city service here. The Seguin Economic Development Corporation lists CenterPoint Energy as the gas provider, and plenty of homes on county roads use propane.

Past the meter, the pipes, fixtures, water heater and gas piping belong to the owner, and that's the work we do.

Homes along the Guadalupe River and the lakes

The Guadalupe flows along the south side of the city, past Max Starcke Park. West of town, Lake McQueeney is a river reservoir managed by the Guadalupe-Blanco River Authority; Lake Placid sits just southwest of the city, and Meadow Lake is on the south side. River and lake houses have their own problems:

• Weekend places. An empty house can leak for days unnoticed. Close the main before you leave; leak detection finds what you can't see.
• Well and septic lots. Outside the city, a lot may run on a private well and a septic tank. If drains back up, stop using water. We clear the line to the tank; pumping goes to septic companies licensed by TCEQ.
• Long buried lines. A leak between the meter or well house and the home shows as a soggy strip of yard or a pump that keeps kicking on (water line repair).

If something breaks after dark

A burst pipe, a sewer backup, a gas smell or water you can't stop is an emergency at any hour: call and we send our on-call plumber right away.

For a water emergency, meanwhile:

1. Turn off the water: the customer valve in the meter box, or the house shutoff if it's closer.
2. On a well, also switch off the pump breaker.
3. On septic, hold off on showers, laundry and flushing.

Area forecasters say Seguin usually sees its first 32-degree night between mid-November and early December. Our freeze prep checklist covers well houses, hose bibs and exposed pipes, and frozen pipes explains how to thaw a line that hasn't split.
