De Cola's Plumbing & Heating describes itself on its BBB page as offering plumbing and heating services. Its website says it has been in business 46 years and names New Haven as its service area. A 2021 customer wrote that a 93 year old steam pipe sprung a leak, spraying rusty water whenever the furnace was running, and that Rich DeCola fit them in ASAP. That 2021 customer called the repair quick and reasonably priced. A 2024 customer wrote that a condo's hot water heater leaked and died, and that Rich scheduled the job for later the same day. That 2024 customer said that on arrival, technician Nick had already removed the old heater and begun installing the new one, and that he cleaned up thoroughly. A 2024 customer wrote that another company had quoted $5000 for a drainage issue that flooded the basement, and that Nick fixed the problem for one tenth of the price. A 2025 customer said Rich called back within 15 minutes of a message left after 5:00pm, and a plumber was there at 8:30 the next morning. A 2025 customer wrote that someone came out to fix their plumbing within a couple of hours of the call, and that the cost seemed reasonable. A 2023 customer had the company do the plumbing for a new kitchen sink and wrote that the sink leaked in the cabinet all the way to the cellar. That 2023 customer said a return visit the next day did not stop the leak, that the company then quoted $175 to come over, and that a different plumber later said the pipe from the new sink drain had been cut too short. A 2023 reviewer called the person on the phone rude. A 2022 reviewer wrote that they had reported the company to the Better Business Bureau.
Responsive, helpful and very patient.
Best plumber in the area!
great service
Rich was great thanks again
Rich from DeCola’s Plumbing and Heating was amazing to work with! He’s truly dedicated to his customers and handled every detail of the project so I didn’t have to think about a thing. DeCola’s was recommended to us by the previous owner of our historic home, who swore by Rich’s expertise and customer service and they were absolutely right. Everything was done with care, on time, and at a fair price. I’m so glad we went with DeCola’s and will definitely be using them again!
