"From Stone Oak to King William, Alamo Heights to the Southside β MC 1 Plumbing knows San Antonio homes inside and out."
San Antonio is one of the most diverse cities in Texas, and its homes show it. From the historic bungalows and Victorians of King William and Monte Vista, to the mid-century ranches around Alamo Heights and Castle Hills, to the newer neighborhoods of Stone Oak, the Dominion, and Alamo Ranch, nearly every era of Texas construction can be found within the city limits. Each one comes with its own plumbing, its own materials, and its own set of problems. San Antonio is home base for MC 1 Plumbing — a veteran-owned, family-operated plumbing company serving the entire city and more than 50 surrounding communities.
MC 1 Plumbing is led by owner Daniel Windler, a Texas Responsible Master Plumber (RMP M-43246) with 30 years in the plumbing trade and a background of military service that shows in how the company works: on time, organized, and focused on doing the job right the first time. Operations Manager Jacqueline Windler keeps scheduling and communication running smoothly, and MC 1's technicians carry the same standards into every home. We're not a national chain or a dispatch center — we're a local San Antonio company, and our customers notice. As one reviewer put it, we're a smaller local company that actually answers the phone and shows up when we say we will.
What sets MC 1 apart is the combination of credentials and honesty behind every job. Along with Daniel's Master Plumber license, MC 1 is TCEQ certified for backflow prevention (BPO025263), which means we can test, repair, and certify backflow assemblies as well as install them. We offer 25 plumbing services, from faucet and toilet repairs to sewer camera inspections, smoke testing, whole-house repiping, and gas line work. Just as important, we take the time to explain what we find and what your options are before any work begins, which is a big reason MC 1 holds a 4.8-star rating on Google.
San Antonio also brings plumbing challenges you won't find in every Texas city. The water here is very hard, and those minerals build up in water heaters, clog faucets and showerheads, and wear out fixtures and appliances years early. The expansive clay soils under much of Bexar County swell in wet weather and shrink in drought, putting stress on slab foundations and the drain and supply lines beneath them. Many older homes still have cast-iron drains and galvanized supply lines that are reaching the end of their lives, mature trees send roots into aging sewer lines, and the occasional hard freeze can split exposed pipes and outdoor faucets.
That's why San Antonio homeowners, landlords, and property managers call MC 1 Plumbing. You get a licensed Master Plumber's experience, a veteran's commitment to doing things right, and a local team that treats your home with respect and gives you straight answers. Whether it's a dripping faucet, a slab leak, a failing water heater, or a sewer line problem, call or text MC 1 Plumbing at 210-500-9085 and work with the plumber who calls San Antonio home.

Answers to the most common questions San Antonio homeowners ask before calling a plumber.
It depends on the job. A faucet repair is very different from a slab leak or a water heater replacement. MC 1 Plumbing explains the problem and gives you a clear estimate before any work begins. Call or text 210-500-9085 for an honest quote on your specific situation.
For most homes, it's worth serious consideration. San Antonio's water is very hard, and the minerals build up in water heaters, faucets, showerheads, and appliances, shortening their lives. A softener reduces that buildup throughout the whole house.
The expansive clay soil under much of Bexar County swells and shrinks with the seasons, putting stress on the pipes beneath slab foundations. Combined with older pipe materials, that makes under-slab leaks a common San Antonio problem. Signs include warm spots on the floor, a running water meter, and unexplained high water bills.
