Kirby Brooks is a great plumber - professional, perfectly on-time, very responsive by phone and did the water heater installation job within the promised timeline. He didn't try to upsell and did the job in a very honest way - its hard to find this now a days. I will hire him again for future jobs at my home. Regarding the quality of the work, I cannot comment right away since he just finished the installation. However, it looks great and there are no apparent leaks. His work comes with a labor warranty as well, just in case if there are any issues.
