"Obsta Plumbing came out the same day when our water heater stopped working. Paul diagnosed the problem quickly, gave us a fair upfront price, and had us back in hot water by that evening. Honest, professional, and genuinely nice people. This is the only plumber I'll call in Katy."

"We had a whole-home repipe done and the crew was incredible. They protected our floors, worked efficiently, and cleaned up every evening. Dorinda was so helpful coordinating everything. The new water pressure is amazing. Highly recommend this family-owned company."

"Called them about a toilet that wouldn't stop running. They came out the same day, fixed it in under an hour, and the price was exactly what they quoted. No upsells, no surprises. I've already recommended Obsta to three neighbors in Cinco Ranch."

"Our kitchen drain was backing up and we had no idea why. They ran a camera down the line and found tree roots — showed us the video and explained everything. Cleared the line and the price was fair. These are honest plumbers who actually explain what's going on."

"We've used Obsta Plumbing for years — they installed our water softener, replaced two water heaters, and handle all our routine maintenance. Always on time, always upfront pricing, always quality work. Paul and Dorinda run a great family business."

"Our restaurant had a major drain backup on a busy weekend. Obsta came out fast, cleared the line, and got us back up and running with minimal downtime. They understand commercial plumbing and they communicate clearly. We use them for all our maintenance now."
