Obsta Plumbing is a family-owned residential plumbing company based in Katy, Texas. Since the early 1990s we've been the plumber Katy and Houston homeowners call when they want the job done once, done right, and explained in plain English.
Every home in the Houston area is different. New builds in Cinco Ranch and Cross Creek Ranch use different materials than 1980s ranch homes in Memorial or older properties in Bellaire. Our technicians know the local building stock, the soil movement that affects slab leaks here on the Gulf Coast, and what it takes to keep your plumbing reliable through Texas heat and the occasional hard freeze.
Whether you need same-day repair, planned maintenance, or a full whole-home repipe, you'll get an upfront quote, no surprise charges, and workmanship backed by our 30+ year reputation in Katy and Houston.
