Mico, Medina County
Hidden, slab, underground and high water bill leaks located across Mico and Medina County. Call our 24/7 line and a specialist will start with your symptoms.
Local leak detection
From a slow drip under a slab to a burst line in the yard, Mico homeowners call us when water is going somewhere it should not. The city is in Medina County, San Antonio and South Central Texas, and is an area of about 2,431 residents across its ZIP codes.
About 85% of homes here are detached single family houses, and the typical home was built around 2005. That mix shapes the leaks we see most often, which is why this page focuses on the problems that actually come up in Mico 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.

Local leak problems
Based on the age and type of homes here, the ground they sit on and local winters.
With 85% detached homes, most on concrete slabs, and clay that swells and shrinks with the seasons, Mico 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.
82% of homes in Mico 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.
Properties around Mico often have long buried lines to barns, shops and guest houses, laid in rocky or caliche ground. Locating the leak before digging matters more here than almost anywhere, because every wrong hole is slow and costly.
Many Mico homes from the last few decades have backyard pools, and clay movement can crack shells and separate skimmers. A bucket test tells you quickly whether you are losing more than Texas evaporation.
According to the U.S. Census Bureau American Community Survey, 2019 to 2023, 4% of homes in the Mico area were built before 1960, 7% between 1960 and 1979, 6% between 1980 and 1999, and 82% since 2000.
Much of Mico 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 93% of occupied homes are owner occupied, so most callers are homeowners deciding on their own repairs.
Mico 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 Mico 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. Around Mico, outdoor taps, attic lines and irrigation backflow preventers take the brunt of it.

Depending on the address, water in the Mico 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.
In Mico, as in most of Texas, the provider maintains the meter and the street side connection and the property owner maintains everything after it, including the service line to the house. Water pooling around the meter is worth a call to your provider; a moving meter with the house shut down is a job for a meter leak investigation.
Nearby communities we also serve include Rio Medina (about 7 miles), Pipe Creek (about 10 miles), Castroville (about 13 miles), Helotes (about 15 miles), Bandera (about 15 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 7671It depends on the address. Parts of the Mico 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.
85% of homes in the Mico 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. Mico 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.
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 Mico home.
We cover 1 ZIP code in the Mico area, including 78056. Nearby areas in Medina 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 Mico, Rio Medina or Pipe Creek, 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 Mico 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.
