Shower faucet cartridge leaking hot water into shower. Christian located the correct replacement and did the re-install correcting our problem. 5 stars represents the work and results but not the high price.

Have you heard about the “cold plunge” craze? After this morning, I’m officially out! Our Navien, Inc tankless unit finally gave up after about 15 years of reliable service. The result? A brutally cold 48° shower to start the day. One call to Roy's Plumbing, Heating & Cooling and by this afternoon we were right back to enjoying endless hot water. If you’ve ever been the last one in line for a shower and stuck with a cold rinse, you know the downside of a traditional hot water tank. Tankless systems heat water on demand, which means you’re not limited by what’s sitting in a tank—you get a continuous supply whenever you need it. In a house with four women plus me, a standard tank just wouldn’t cut it. With our Navien system, we can run both showers, do laundry, and wash dishes all at the same time—no one gets stuck shivering! Big thanks to Michael and John for helping us choose the perfect new Navien unit, and to Tyler and Mike for making quick work of the installation. Everyone was friendly, professional, and made the whole experience easy. (Aside from that one very cold shower. 💦🥶) If you’re thinking about upgrading, “Just call Roy’s!”—you’ll be glad you did!

Our sewer got backed up and Roy's Plumbing came to the rescue. Not only did they clear the blockage, but they also used a camera to inspect the entire run to be sure it was completely cleared. Very grateful for the perseverance to clear out the sludge. Matt is an absolute stud. Just a powerhouse of a plumber with the voice of an angel. I would highly recommend these guys!
