Duncan Plumbing & Heating is a family-owned Norwood company led by master plumber Dwight Duncan, which says it has served Norwood and nearby towns — Canton, Dedham, Needham, Westwood, Walpole, Sharon and others — for more than 35 years. Its Massachusetts plumbing licence is active on the state registry. In an October 2025 review, a condominium complex said Jeremy handled a multi-part plumbing project quickly and thoroughly. A 2024 reviewer said the crew double-checked everything before diagnosing a problem that had dogged them for months, and a 2022 customer said they arrived quickly with the parts on the truck. The one complaint, from 2023, is from a caller who said their calls were repeatedly picked up and hung up on within ten minutes. Google shows 4.4★ from 14 ratings, and the BBB grade is A+.
Very good team ! Humble and professional! Highly recommend
Jeremy from Duncan came to our condominium complex to take care of a multi faceted plumbing project. He was a pleasure to work with, handled the job quickly and thoroughly. Definitely recommend
I called in the morning, Dwight answered immediately. By noon, J was on site and was taking care of my boiler. Very efficient and good communication.
Took the time to ensure everything was double checked and examined before diagnosing the issue that had been plaguing us for months! Would recommend to any friends or family that need plumbing
It is wired that he picks up my calls and immediately hung his phone when I was trying ask service from him. It happened not once, multiple times within 10 minutes period. Looks like he is running his business for namesake. never ever try to call and waste your time.
