"Fast, helpful, professional, and fair pricing. I recently had a sump pump failure which ruined my hot water heater heaters. I reached out to several companies and Dr Water Heater responded quickly and prioritized the timing of the team’s visit. I was without hot water so a few days made a big difference! The entire process was helpful without making me feel pressured, and extremely thorough and professional throughout. I would highly recommend this service."

"They care! They stopped by to address a hot water heater on the blink but the weather was brutally cold and Mikey saw me working on the boiler… After addressing a plan to convert to tankless, he helped me make the decision to switch to a tankless combi solution. Very happy how the team took the time to complete the job timely. I will use them for other projects for sure"

Customers say: True professional

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"When our basement's pipe and water filter unexpectedly burst, Delroy from Pipe Works Services came to our rescue. He arrived promptly, assessed our situation, and helped us choose a cost-effective yet highly functional solution. Delroy swiftly installed new piping, pressure valves, and a water filter with great attention to detail. We wholeheartedly recommend Pipe Works Services for all your plumbing needs, including their 24-hour emergency services—be sure to request Delroy!"
