"Neo did an excellent job replacing the pedestal sink in our very old condo. He left the area very clean. He was quick to respond to our questions before and after the work and was always courteous."

"Scott came to my house on time and was able to pinpoint the problem with my toilet very quickly. Explained everything clearly, told me how much time it would take and gave me a fair price. I had another plumber, a friend,fix and replace the toilet two years ago,didn't fix it properly and charged me twice the price. I am extremely happy. Scott was on time, knowledgeable, pleasant and didn't leave my bathroom a mess. I had Scott replace a leaking faucet while he was there. I am thrilled to have found this gem of a plumbing company and would highly recommend them to anyone. I have their business card on my fridge, I know who to call in the future. Thank you for your professionalism."

"Angel from Dynamic plumbing helped me in hooking up new gas dryer. He has very friendly, knowledge and honest in his work. He told me upfront how much it would cost, and he didn’t even charge for the additional fixes that was needed for the vent. He also told us about safety issues related to gas dryers. I highly recommend this company, and will hire them for any future plumbing need."

"Highly satisfied AGAIN in a second job with Mouradian (hot water heater earlier). This time was a replacement of leaking cast iron sink waste pipe imbedded in the wall/floor between two condo unit bathrooms. Eric Mouradian is very no-nonsense, fast in his estimates, and reasonable in his pricing. The plumber who did the job, Rich, was excellent: friendly, efficient, and clear about what was going on. He understood immediately that his first instinct, to open up the ceiling and wall of the downstairs bathroom should be avoided if possible, to limit wall repairs to one bathroom instead of two. And he then quickly figured out how to do it and did it. The cost was considerably less than the quote of a competitor, who misdiagnosed the problem at first, refused to put his quote in writing, and showed no interest in keeping wall damage to a minimum. No comparison."

"My grandson flushed his little yellow bus down the toilet Friday afternoon. I called several plumbers in the area. By late Saturday afternoon I had only 1 returned call saying they could come out Monday morning. A friend suggested I call Gentille Plumbing and Heating. I called them and they said they could come early Sunday morning. Ryan arrived promptly as promise and quickly determine how to approach the issue and retrieved the little yellow bus. Cleanup was quick and pricing fair. Ryan was professional , friendly and was on his way within 45 minutes of arrival. Thank You Gentille Plumbing and Heating"
