"I recently had my old water heater replaced by 100% Plumbing Houston, and I couldn't be more impressed with the entire experience. From the moment I called for an estimate, they were professional and transparent about the process and pricing. The technician, who arrived right on schedule, was fantastic. He was very knowledgeable, answering all of my questions and helping me choose the right new unit for my home. The installation itself was seamless. He worked efficiently, carefully removed the old unit, and had the new water heater installed and running in no time. He made sure to test everything and even took the time to explain the new unit's features to me. What really stood out was how clean and tidy they were. They put down coverings to protect my floors and left the work area spotless. My new water heater is working perfectly, providing plenty of hot water without any issues.
