Job Locations and Reviews
Tub spout leaking
Recently, I completed a thorough flush of a tankless water heater. The process began with a detailed inspection to identify any signs of sediment buildup or mineral deposits. Using specialized tools, I carefully accessed the internal components of the water heater. I then employed a high-pressure water flush to remove accumulated debris, ensuring optimal performance and efficiency. Throughout the procedure, I maintained a meticulous approach to prevent any damage to the unit. Post-flush, I conducted a comprehensive test to confirm that the water heater was operating smoothly and efficiently. This maintenance not only extended the lifespan of the appliance but also ensured consistent hot water supply.
Shower leak

George has worked on our plumbing previously. He is always very good at explaining what he is going to do and is quick, neat and very professional. He does an outstanding job.
I saw a leak in the front of my house at 5 pm and it looked bad. I got an emergency plumber at my house and he fixed the main water connection to my house right away. All the other Plumbers I called would make me wait 2 days to a week to come by and given the leak I could not wait. I would use Duncan again with my next plumbing problem cause get it done!
Jorge was very competent. He did an excellent job. The price was pretty steep, but Jorge doesn't set Duncan's prices.
Very Good Experience
Quick / Great Service
Wonderful job first removing old bathroom plumbing fixtures and then after new tile done, installing new sink with fixtures and tub/shower fixtures. Very happy the outcome!
All the people from Duncan were communicative, clear, punctual, and effective.
Onsite staff and office staff were professional and extremely courteous.
I live in a house built in 1941. If you live in an old house it is a very good idea to find a plumber you can trust. Duncan Plumbing has been that company for me. This Saturday it was the hot water heater leaking from a valve on top of the hot water heater. By noon Sunday Duncan Plumbing was at my door (properly masked poor guy; it was almost 100 degrees) and discussed my options with me. He was pretty straightforward and I decided to replace the hot water heater instead of repairing. In a few hours he was done and cleaned up...that is one of the nice parts. I will call them again and again, because that is what happens when you live in a house built in 1941!
Duncan plumping was very easy to work with! I would Choose them again for any other plumping work i might need!
