Local leak problems

Leak Problems We See Most In Seguin

Based on the age and type of homes here, the ground they sit on and local winters.

Slab Leaks Under Shifting Ground

With 68% detached homes, most on concrete slabs, and clay that swells and shrinks with the seasons, Seguin sees the classic Texas slab leak: a copper line under the foundation wears through where the slab moves. Warm floor spots, a busy water heater and a meter that keeps turning are the usual clues.

Pipes From The Polybutylene Era

About 32% of Seguin homes were built between 1980 and 1999. Many from that period were plumbed with polybutylene or early copper, and both are now at an age where fittings crack and pinholes form. Isolating and pressure testing each line shows which run is failing.

Water Leak Detection →

Leaks Under Older And Raised Homes

16% of homes predate 1960 and 19% are manufactured homes, so a good share of Seguin plumbing runs under raised floors. Those lines are exposed to cold and rarely inspected, which lets a slow leak soak joists and insulation for months.

Aging And Shared Service Lines

With 4 water systems registered locally and many older lots, service lines in Seguin vary widely in age, material and route. A leak between the meter and the house shows as low pressure, a wet meter box or a soggy strip across the yard.

Homes In Seguin And What That Means For Leaks

According to the U.S. Census Bureau American Community Survey, 2019 to 2023, 16% of homes in the Seguin area were built before 1960, 20% between 1960 and 1979, 32% between 1980 and 1999, and 32% since 2000.

A large share of Seguin homes date from 1980 to 1999. Polybutylene, the gray plastic supply pipe installed in many homes from roughly 1978 to 1995, can turn brittle and fail at its fittings, and copper lines from the same era are now reaching the age when pinhole leaks start.

About 19% of homes are manufactured or mobile homes, where supply and drain lines run under the floor and are exposed to cold.

Ground And Weather In Guadalupe County

Seguin lies in San Antonio and South Central Texas. North and west of San Antonio, the land rises onto the limestone and caliche of the Edwards Plateau. To the south and east, clay and sandy loam soils take over. Limestone and caliche make blind digging difficult in the Hill Country suburbs, while clay areas see the familiar pattern of slab movement and under slab leaks.

The Seguin area is in USDA Plant Hardiness Zone 9a, which means the coldest night of a typical winter drops to about 20 to 25 degrees Fahrenheit. Hard freezes are uncommon, but Winter Storm Uri in February 2021 brought freezing temperatures to nearly all of Texas, and homes here are rarely built with freezes in mind.

Long, hot summers, mild winters and occasional hard freezes, with heavy rain events that can follow dry periods. Along Interstate 10 and the rest of the Seguin area, outdoor taps, attic lines and irrigation backflow preventers take the brunt of it.

Who Supplies Water In Seguin

The main public water system for Seguin is City of Seguin, listed in the EPA Safe Drinking Water Information System as system TX0940002, serving about 32,736 people.

There are also 3 other community water systems registered with a Seguin address, including Springs Hill SUD and Memory Lane Mhp, so neighbors on different streets can have different providers and rules.

Responsibility usually splits at the meter. Anything on the street side is a matter for City of Seguin; the line from the meter to your Seguin house and all the plumbing inside are yours. A meter that keeps turning with everything shut off in a 78155 home points to a leak on the owner's side, which is where high water bill testing comes in.

Who Supplies Water In Seguin, And Who Fixes A Leak At The Meter?

The main public system is City of Seguin. In most Texas systems the provider maintains the meter and the pipe on the street side, while the owner is responsible from the meter to the house. If water is coming up at the meter, call the provider on your bill first. If the meter moves with everything off, the leak is on your side.

Are Slab Leaks Common In Seguin?

68% of homes in the Seguin area are detached houses, and most Texas houses from the 1960s onward sit on concrete slabs with water lines beneath. The local clay swells and shrinks with the seasons, which stresses those lines. Warm floor spots, a water heater that runs constantly and a moving meter are the signs to watch for.

Can Pipes Freeze In Seguin?

Yes. Seguin is in USDA zone 9a, where a typical winter's coldest night reaches about 20 to 25 degrees Fahrenheit, and severe events like February 2021 go well below that. Pipes in attics, exterior walls, crawl spaces and above ground backflow preventers are most at risk. Some cracks only leak after the thaw.

How Do I Check My Seguin Home For A Leak Before Calling?

Turn off every faucet, appliance and sprinkler zone, then open the meter box, the one City of Seguin reads each month, and watch the small triangle or star shaped low flow indicator. If it moves over 15 minutes, water is leaking. Close the main shutoff at the house: if it still moves, the leak is probably on the service line to your Seguin home.

Which Seguin ZIP Codes Do You Cover?

We cover 1 ZIP code in the Seguin area, including 78155. Nearby areas in Guadalupe County and beyond are covered too, so call even if your address is on the edge of town.

How Quickly Can Someone Come Out In Seguin?

Our line is answered 24 hours a day, 7 days a week. When you call from Seguin, McQueeney or Geronimo, the specialist confirms availability and an arrival window on the call, and for an active leak talks you through shutting off the water while you wait.

What Does Leak Detection Cost In Seguin?

It depends on the leak. In Seguin the most common job is slab leaks under shifting ground, and cost varies with how many lines need testing, whether the leak is under concrete or in the yard, and whether it is an after hours emergency. You will hear how pricing works on the call before anyone is sent.
