A word of thanks. I had a Navien water heater installed in December 2020. The installers, Tommy and James, arrived a little early and were ready to work right away. They let me know what to do and what to expect as they went through various phases of the install process. At the end of the day they showed me features of the water heater and answered any questions. After they left I noticed that they left no trash or clutter. Tommy and James are great professionals. Their attitude, knowledge, and professionalism reflects well upon themselves and Schwartz Plumbing. Thank you for having great installers like James and Tommy!
