I recently had Darnold & Lyons Plumbing install a Navien tankless water heater, and I couldn't be more impressed with the experience from start to finish. The owner, Grant, came out in the morning to review the space and walk me through the different options. He clearly explained the pros and cons of each type of water heater, provided a competitive quote before lunch, and was able to put me on the schedule for the very next day. On installation day, Josh and his apprentice arrived promptly in the afternoon after completing another job. They worked efficiently to remove my old unit and ensured my water was back on quickly. Josh then carefully planned the new setup, designed the configuration, and created a supply list to be ready for the next day's work. The following morning, the team arrived before 9 a.m. and worked straight through until early evening. The installation required new water and gas lines, which they configured and brought up to code. As the day progressed, Josh called in additional support, and two more team members arrived to install the PVC exhaust system. Their teamwork and attention to detail were outstanding. Josh, in particular, deserves special mention. He is professional, efficient, and kind--a combination that makes the entire process stress-free. While the cost of plumbing work is always an investment, I have every confidence that this installation was done right and will stand the test of time. I highly recommend Darnold & Lyons Plumbing for their professionalism, responsiveness, and quality of work. read more

My family decided to try Darnold & Lyons when our furnace stopped working during the coldest week of the year. When I called, the woman answering the phone was friendly and scheduled a technician to visit our home in less than 24 hours. The technician, John, arrived during the scheduled time and even called when he was on his way. He was very knowledgeable and efficient and had our furnace working in no time...and all for an extremely reasonable price! I couldn't be more pleased with our experience. I will definitely schedule regular maintenance with Darnold & Lyons for our home and business so we don't have this trouble again! We're so happy to have found such a trustworthy company and plan to be customers for many years to come! read more
