We are a locally owned and operated company that values honesty and integrity, and treats your home as if it were our own. Our only priority is to provide the highest level of customer service. We know that plumbing emergencies are enough of a headache without dealing with an ornery customer service rep or repairman. We offer a warm voice, a courteous call, and a convenient process. We make your emergency a priority for us, scheduling service as quickly as possible to resolve your problem. Our plumbers are the same way—they treat your home with respect and consideration. We wipe our feet on our own mats, we wear shoe covers before entering your home, and we’ll offer you a fair assessment of your plumbing situation and how much it will cost to handle it. Our prices are flat-rate and upfront, so you don’t have to worry about inflating prices as the job goes on.

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."

Our company was created from our two founders’ shared vision to combine industry-leading knowledge and expertise, with a passion for service excellence, to operate as THE Water Heater Company. Our entire team is united in this quest to be the best. We continuously train, we work together to exceed expectations, and we get better every day. Our goal is to provide our community with the highest quality service and solutions — proudly working every day to earn our reputation as Your Trusted Water Heater Authority.

"Such a good experience from beginning to end! I came back from a trip to find my water heater was leaking all over the place. I was referred to THE Water Heater Company by some friends, whose opinions I hold in high regard, and I was not disappointed. The company gave me straightforward options and said they could respond the next day and would likely be able to replace my water heater that same day. Marc was able to remove my old water heater and replace it with a great brand in the time he said it would take; moving everything up and down 3 flights of stairs and working in a small space. A great experience from start to finish: thorough review of existing equipment and services; thorough explanation of available options and explained better versus worse options; they said what they were going to do and delivered on that. Everything was straightforward and handled efficiently. It was also great to have someone who takes pride and is enthusiastic about the work they do. If every interaction in my day was like this one, I would never have anything to worry about. A big thank you to THE Water Heater Company and to Marc!"

Water heater repair or services FAQs

Flushing your water heater helps prevent mineral deposits from building up. It removes sediment that would otherwise insulate the heating element and slow heat transfer. Proactive maintenance ensures that your water heater maintains a consistent temperature while operating efficiently and extends its lifespan so you have a long-term, dependable hot water source.

Plan on flushing your water heater once a year. If you have hard water with high calcium levels, consider flushing it twice a year to keep it running smoothly. Regular flushing helps prevent sediment buildup, ensures that reliable hot water is readily available, and extends the life of your water heater.

If you notice unusual noises from your water heater, inconsistent water temperatures, rusty or cloudy water, leaks near the drain valve, or higher utility bills, it's time to flush your water heater. These signs indicate that sediment buildup is affecting your heater’s performance. Professional flushing service can help restore your water heater’s efficiency and prevent further issues.
