Local leak detection
From a slow drip under a slab to a burst line in the yard, La Marque homeowners call us when water is going somewhere it should not. The city is in Galveston County, Greater Houston and the Upper Gulf Coast, and is home to about 18,833 people.
About 87% of homes here are detached single family houses, and the typical home was built around 1983. That mix shapes the leaks we see most often, which is why this page focuses on the problems that actually come up in La Marque rather than a generic checklist.
Figures from the U.S. Census Bureau American Community Survey 2019 to 2023 five year estimates and the USDA Plant Hardiness Zone Map.

Close the main shutoff valve, then call. We answer 24/7.

Based on the age and type of homes here, the ground they sit on and local winters.
With 87% detached homes, most on concrete slabs, and clay that swells and shrinks with the seasons, La Marque 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.
41% of homes in La Marque were built after 2000, many with automatic sprinklers. Buried irrigation mains and zone valves leak quietly, and in a Texas summer one bad zone can add more to the bill than the whole house.
21% of homes predate 1960 and 2% are manufactured homes, so a good share of La Marque 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.
With 1 water systems registered locally and many older lots, service lines in La Marque 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.
According to the U.S. Census Bureau American Community Survey, 2019 to 2023, 21% of homes in the La Marque area were built before 1960, 27% between 1960 and 1979, 11% between 1980 and 1999, and 41% since 2000.
Much of La Marque has been built since 2000. Newer homes mostly use PEX and CPVC, which rarely fail along the pipe but can leak at crimp rings, fittings and valves, and new subdivisions often come with automatic sprinkler systems whose buried lines are easy to damage.
The soil under La Marque matters for leaks. The coastal prairie here is dominated by dense, highly expansive clays over a shallow water table, and parts of Harris, Galveston and Fort Bend counties have a long history of ground subsidence. In Galveston County that means clay movement and a wet subsoil put steady stress on slab plumbing and buried service lines, and the humid climate means a hidden leak quickly turns into mold.
The La Marque area is in USDA Plant Hardiness Zone 9b, which means the coldest night of a typical winter drops to about 25 to 30 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.
The climate is hot and humid with heavy rain events and tropical storms. Hard freezes are less frequent than in North Texas but do happen, as February 2021 showed. Along Interstate 45 and the rest of the La Marque area, outdoor taps, attic lines and irrigation backflow preventers take the brunt of it.

The main public water system for La Marque is City of La Marque, listed in the EPA Safe Drinking Water Information System as system TX0840006, serving about 15,154 people.
For a typical La Marque home, City of La Marque looks after the meter and the pipe on the street side, while the service line from the meter to the house belongs to the owner. If water is bubbling up at the meter box, report it to City of La Marque first. If the dial moves with every tap off, the leak is on your side, and a meter leak test is where we start.
Main numbered routes through the La Marque area include Interstate 45, State Highway 3, State Highway 6 and Farm to Market Road 1764, and we cover addresses along all of them.
Nearby communities we also serve include Hitchcock (about 6 miles), Santa Fe (about 7 miles), Dickinson (about 7 miles), Texas City (about 8 miles), Bacliff (about 10 miles).

Lines are isolated and tested so the search covers one run, not the whole property.
Acoustic, thermal, moisture and tracer gas tools find the leak before anything is opened.
You hear where the leak is, what likely caused it and your repair options in plain language.
Shoe covers, careful access and a tidy work area every visit.

(800) 901 7671The main public system is City of La Marque. 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.
87% of homes in the La Marque 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.
Yes. La Marque is in USDA zone 9b, where a typical winter's coldest night reaches about 25 to 30 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.
Turn off every faucet, appliance and sprinkler zone, then open the meter box, the one City of La Marque 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 La Marque home.
We cover 1 ZIP code in the La Marque area, including 77568. Nearby areas in Galveston County and beyond are covered too, so call even if your address is on the edge of town.
Our line is answered 24 hours a day, 7 days a week. When you call from La Marque, Hitchcock or Santa Fe, 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.
It depends on the leak. In La Marque 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.
Age matters. 48% of homes in the area were built before 1980, when galvanized steel and early copper were standard. Those materials corrode and thin with hard water, so pinhole leaks and joint failures become more likely as the decades pass.
