"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"Aldo replied my request in no time and came very quickly. He fixed the issue very well. I highly recommend Aldo for plumbing repair."

"We woke up to find we had no hot water. When we went down to the basement, we found the water heater had leaked most of its contents all over our basement. We immediately began cleanup and called Comfort Masters. Soon after Chris arrived and determined a new water heater was necessary. Within the next hour, the water heater was disconnected and removed. Only an hour later, Chris returned with a replacement water heater and had it installed soon after. What started as a day where we were concerned about a huge cost and days without hot water got resolved quickly for less than we thought. Chris and Comfort Masters made this possible."

"Came early and removed and installed a new water heater within 90 minutes"

"We had a standard water tank that failed on Friday July 1. I reached out to Matt with water issues from the tank, but more importantly- to find out options for a replacement. He convinced me to go with a popular and reliable tankless system. I called him at 7:40am, the parts were delivered at 11am and Matt came by at 1pm. By 3:30pm, our new system was operational. Going into a holiday weekend - that was fantastic service!"

"Louis Schede came to assess my job at my home to replace my hot water heater (at my request), even though he had seen pictures of my hot water heater and knew that it needed to be replaced. His men were extremely professional and skilled - and a pleasure to have in my home. Not only did Louis Schede have the exact same hot water heater that I wanted in stock, during the job, his men detected that I needed a new suspension tank for my oil burner - and managed to replace that as well on the same day - without going outside of my budget. Louis Schede told me that he has been in business for 50 years and it definitely shows. He is a humble guy, and will work within your budget to do the best, possible job. I will be calling Schede & Sons for future plumbing needs. Thank you, Andrea/Greenwich, CT"
