Sunnyvale plumbers serving upscale large-lot homes — careful, non-invasive service for acreage and estate properties.
Sunnyvale is an affluent rural-suburban community east of Dallas with large-lot estate homes built mostly from the 1990s through the 2010s, plus older ranch properties. Longer water lines, some septic systems, and expansive clay soil make slab leaks and hard-water scaling common here. MasterTex provides careful, non-invasive leak detection and plumbing repair suited to Sunnyvale's larger properties and higher-end fixtures.

"We had a great experience with Mastertex. They repaired our A/C drain under the house including excavation, and the whole process was handled professionally. The plumbers (Connor, Clint, Austin, and the excavation team) who came out were knowledgeable, courteous, and took time to answer all of our questions. They were very helpful, and we really appreciated their patience. The repair was completed well, and we’d recommend them to anyone needing plumbing services. Thank you for a job well done."
"⭐️⭐️⭐️⭐️⭐️ Unfortunately, I now know WAY too much about plumbing. This is not a review I ever expected to write because, frankly, nobody wants to need a plumber. Nobody wakes up thinking, “You know what would really improve my week? A full-house plumbing replacement.” 😂 But here we are. I had the entire plumbing system in my old house replaced, which was easily one of the most painful financial moments of my life. I briefly considered selling a kidney. Then I remembered kidneys are apparently not worth what plumbing costs. 😂 Enter MasterTex, Conner, and Austin. These guys were FANTASTIC. At one point, I had 20–25 people working on my house. TWENTY-FIVE. I have attended weddings with fewer people. And somehow, despite having what looked like an entire plumbing army occupying my home, everyone was professional, respectful, courteous, and incredibly considerate. They tackled a massive job with a great attitude and never made me feel like I was living in the middle of a construction war zone. They communicated, worked hard, cleaned up, and treated my home and belongings with respect throughout the entire process. Was I thrilled to pay for a brand-new plumbing system? No. Would I rather be on some European vacation or a cruise around the world? Duh! Was I thrilled with the people who installed it? Absolutely. In fact, I am almost offended by how pleasant they made the worst financial experience of my life. 😂 So if you’re sitting there thinking, “I really hope I never need a plumber…” Same. But when your house inevitably decides to financially ruin you through the plumbing, Call MasterTex. Because if you have to spend the money, you might as well have a company that sends an army of incredibly professional people into your house who actually know what they’re doing. ⭐️⭐️⭐️⭐️⭐️ Would absolutely recommend. Would absolutely use them again. Would absolutely prefer not to need them again. 😂 Thank you to the entire MasterTex crew. You guys were seriously awesome."
"Connor & team were so informative when they came to my house and checked my sewage lines to make sure everything was in order. He also checked around my house for possible foundation issues. This really helps being a single female! I appreciate this company!"
"Great experience! The appointment was scheduled quickly, and the plumbers was professional, knowledgeable, and efficient. They were able to assess and address the issue right away and had everything resolved within an hour. Throughout the visit, they kept me informed about what was being done and took the time to educate me on how to help prevent similar issues in the future. I really appreciated the communication and expertise. Highly recommend"
"Turns out I had a disposal problem rather than a plumbing problem, much to my relief. They were only here for about 30 minutes to diagnose the problem and charged their most reasonable price to do so. Connor and Davis are fast and friendly."
"I had a leaking water heater that needed replacing and called, thinking it would take days. They called back with a fair quote and came out the same day to install. Went above and beyond and did a great job. Highly recommend!"
