"Agustin.R from Otisville ,NY Seth came to my home and explain ,what needed to be done.How much it was going to cost and loan me a temporary boiler until they installed my New Indirect water heater.Him and the Workers were great. While in my home the workers notice that a valve needed changing they explained what would happened if We kept it longer so they changed it. I am very happy with the work and will use him again.I felt they were honest and skillful!!!"

"The technician was very knowledgeable and explained the problem and the solution options clearly. The installation of the additional equipment needed to get the heating working properly was very well done. From the initial phone call to job completion, it was a very good experience."

"Kevan (spelled with an "a") was the only plumber who even called me back the day after Christmas. All these other companies that advertise 24/7 & Holidays emergency service did not even answer the phone. We lost power and our pipes froze in super cold weather we had Christmas 2022. In 32 years my pipes never froze but they did this time and they burst in multiple locations. Kevin called and came out the same day and worked into the night replacing multiple ruptures. He is extremely courteous and professional and I HIGHLY RECOMMEND HIM for any plumbing or water treatment needs. Ken H., New Paltz, NY."

"I was honestly in a panic when the weather started changing because I knew I needed my water tank replaced as soon as possible. Thankfully, Dom came through! His response time was absolutely immaculate, and he understood the urgency of the situation and made the entire process so much less stressful. From his professionalism to the quality of his work, everything was top notch. It’s such a relief to find someone reliable who genuinely cares about getting the job done right. I highly recommend Dom to anyone needing a water tank replacement. Excellent service from start to finish."
