Local leak detection
Leak detection in Spring Branch starts with knowing the local housing and ground. Spring Branch sits in Comal County in San Antonio and South Central Texas and is home to about 260 people, spread across 1 ZIP code we serve.
About 78% of homes here are detached single family houses, and the typical home was built around 2006. That mix shapes the leaks we see most often, which is why this page focuses on the problems that actually come up in Spring Branch 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.

Based on the age and type of homes here, the ground they sit on and local winters.
With 78% detached homes, most on concrete slabs, and clay that swells and shrinks with the seasons, Spring Branch 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.
66% of homes in Spring Branch 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.
About 29% of Spring Branch 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.
2% of homes predate 1960 and 17% are manufactured homes, so a good share of Spring Branch 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.
According to the U.S. Census Bureau American Community Survey, 2019 to 2023, 2% of homes in the Spring Branch area were built before 1960, 4% between 1960 and 1979, 29% between 1980 and 1999, and 66% since 2000.
Much of Spring Branch 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.
About 17% of homes are manufactured or mobile homes, where supply and drain lines run under the floor and are exposed to cold. About 91% of occupied homes are owner occupied, so most callers are homeowners deciding on their own repairs.
Spring Branch 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 Spring Branch area is in USDA Plant Hardiness Zone 8b, which means the coldest night of a typical winter drops to about 15 to 20 degrees Fahrenheit. A few hard freezes arrive most winters, and a severe cold snap like February 2021 can split pipes in attics, exterior walls and crawl spaces.
Long, hot summers, mild winters and occasional hard freezes, with heavy rain events that can follow dry periods. Along US Highway 281 and the rest of the Spring Branch area, outdoor taps, attic lines and irrigation backflow preventers take the brunt of it.

Depending on the address, water in the Spring Branch area can come from a city system, a municipal utility district or a water supply corporation. The provider's name is printed on your water bill.
There are also 2 other community water systems registered with a Spring Branch address, including Cypress Cove WSC and Spring Branch Indian Hills Estates WSC, so neighbors on different streets can have different providers and rules.
For a typical Spring Branch home, your provider 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 your provider 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 Spring Branch area include US Highway 281, and we cover addresses along all of them.
Nearby communities we also serve include Bulverde (about 7 miles), Kendalia (about 8 miles), Canyon Lake (about 9 miles), Bergheim (about 11 miles), Fischer (about 13 miles).

Why Texas Leak Detection Experts
Most plumbers can fix a pipe. Fewer can tell you exactly where an invisible leak is without opening walls, floors or the yard. Leak detection is that one job, done with the right equipment and a methodical process, so the repair is small and done once.
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 7671It depends on the address. Parts of the Spring Branch area are served by city systems, municipal utility districts or water supply corporations, each with its own rules. Your provider is printed on your water bill, and they can confirm where their responsibility ends, usually at the meter.
78% of homes in the Spring Branch 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. Spring Branch is in USDA zone 8b, where a typical winter's coldest night reaches about 15 to 20 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 your water provider 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 Spring Branch home.
We cover 1 ZIP code in the Spring Branch area, including 78070. Nearby areas in Comal County and beyond are covered too, so call even if your address is on the edge of town.

It depends on the leak. In Spring Branch 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.
