"Serving the Little Alsace of Texas with veteran-grade reliability — from historic Houston Square to rural Medina County properties."
Castroville holds a unique place in Texas history — founded in 1844 by Alsatian settlers and nicknamed "the Little Alsace of Texas," it's one of the most culturally distinctive small towns in the entire state. From Houston Square and the Landmark Inn, to the limestone homesteads along the Medina River, Castroville is a living piece of Texas heritage — and it comes with plumbing realities you won't find in bigger cities.
Many Castroville properties are rural, sit on larger acreage, and run on private wells and septic systems rather than municipal utilities. Daniel Windler of MC 1 Plumbing understands rural Medina County plumbing — from well pumps and pressure tanks, to septic-to-sewer transitions in the growing parts of town, to the unique challenges of maintaining plumbing in 150-year-old Alsatian homes.
Here's what makes Castroville plumbing different: well water in the Medina River basin often carries significant iron, calcium, and sediment, and that takes a toll on every plumbing fixture in the house. Add in septic systems that need monitoring, galvanized supply lines still present in pre-1970s homes, and the clay-to-caliche soil common in Medina County — and you have a plumbing environment that rewards local experience.
Whether your Castroville home is a historic Alsatian stone structure near the downtown district, a mid-century ranch off FM 471, or a new-construction home in one of the county's growing subdivisions — MC 1 Plumbing brings 30 years of Texas plumbing experience, full state licensing (RMP M-43246), and TCEQ backflow certification to every service call. We understand rural plumbing. We understand old homes. We understand Castroville.
If you're dealing with well water issues, a failing water heater, septic line trouble, or just need an honest quote from a licensed Texas plumber who won't try to upsell you — call MC 1 Plumbing. Veteran-owned, family-operated, and proud to serve the Little Alsace. 🔧

"We moved into a historic home off Houston Square and discovered the old galvanized supply lines were failing. Daniel gave us a clear plan, did the re-pipe over two days, and worked respectfully with the old structure. Couldn't have asked for a better experience."
— Michael & Tracy L.

"Our well pump died on a Sunday evening. MC 1 came out early Monday, diagnosed it fast, replaced the pump and pressure tank, and had us back in water the same day. Fair price, straight talk. He's our plumber from now on."
— Sam R.
