"Awesome service by N&J plumbing"

"Professional, courteous, responsive, and fair price. I highly recommend and will use them again. E and R Plumbing was 1 of 3 companies recommended to me by HomeAdvisor and I contacted them because they had the best reviews. Almost immediately, I received a call from Rich and while he was on the phone, he asked me to send over pictures of my 16 year old Water Heater Tank that needed to be replaced. He quoted me a fair price for both a Tank and Tankless water heater and I decided to go Tankless. Rich and two colleagues showed up the next morning, removed the old Water Heater Tank and built out a plywood mount to install a new tankless water heater directly behind where the old tank was, taking up less space. Rich and his colleagues completed the job exactly as described, and Rich called later that afternoon to make sure everything was running great!"

"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."

"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"
