Kurtis did an absolutely amazing job with my water heater. From start to finish, he was professional, knowledgeable, and took the time to explain everything in detail. He quickly diagnosed the issue, walked me through the options, and made sure the work was done properly and safely. You can tell he takes pride in his work and genuinely cares about doing things the right way. The whole process was smooth, stress-free, and I’m extremely happy with the results. I wouldn’t hesitate to recommend Kurtis to anyone looking for reliable, honest service.
