Do You Have an Urgent Plumbing Problem That Can’t Wait?
So happy we did this rebuild/upgrade. Our original radiant heat system was 18 years old, not well installed in the first place and showing signs of imminent failure. So we did our due diligence, had three conversations with three companies and Duncan Plumbing was by far the best choice. Duncan Plumbing sent their technician, Jedidiah (Jed), and we got started with the preliminaries. Jed took plenty of time to assess, calculate and determine the best long-term solutions. Here's what we ended up with: Plan A - high end proposal Plab B - medium end proposal Plan C - lower end option We chose the high end proposal as it made the most sense given the overall condition of many of the existing components. Pros and cons: Pros - Always on time and in communication Three proposals on the spot that day Jed made the proposal and did the job Stayed exactly on proposed cost Stayed exactly on schedule (done early) Perfection in craftsmanship Pride in job Clean up everything during/after job Streamlined/more efficient results Answered all questions at any time Expert knowledge (hard to find) Courteous and professional Cons - Really ... none At the end of the day (or job) could not be happier! Strongly recommend!! Wish I could share a before picture but don't have. Look at the after picture and judge for yourself.
JC with Duncan was great. He communicated consistently, trouble-shot the problem, and offered us different options and pricing to solve the problem. Would definitely recommend and am planning to use again if we have future issues.
Duncan's crews are always professional and conduct excellent work in a timely manner and they are very respectful, even when dealing with our high maintenance dogs.
We have a house with 60+ year old plumbing. Over the 40+ years of our residence in the home, we've contacted Duncan Plumbing whenever there's been an issue, and Duncan has always sent capable crews out quickly to assess and deal with our various clogged drains. They have almost always recommended, at the end of their visits, that we consider a whole-house upgrade of the pipes and drains.
This April, when horrible black guck started bubbling up out of our bathtub drain, Nick, Frank, and Zack from Duncan responded quickly. They immediately and correctly ascertained that a plant root in the front yard was clogging the main sewage drain to the street. They used their camera snake to target and show us photos of the problem, then sent in their rotor machine to break down the root, which fixed the bathtub drain problem. Finally, they again strongly urged us to upgrade water and drain pipes. Duncan sent us an estimate. It was painfully expensive, but we finally agreed to go through with the project. It took about a week and required that the crew traipse through our bedroom to access the under house crawl space, but I can't imagine a more sensitive, considerate, knowledgeable, and professional team than Nick, Frank, and Zack.
When we saw the condition of the old drains and pipes they were removing, we were grateful we were getting new plumbing – apparently just in time!
Duncan Plumbing's office staff was also terrific to work with. We highly recommend Duncan plumbing.
Jed Kraft was professional, friendly and courteous. Effective with his work, humoured my questions and offered several insightful comments on things to watch out for in the future given our extensive home renovations. Highly recommend this plumber!
Regarding our Rinnai tankless water heater: on May 14, 2025, Frank and Matt fixed an error code (#63) and did an annual check-up. We are very satisfied with their work and how they communicated with my wife and me.
Duncan Plumbing office staff responded to my voicemail message quickly to get my failing water heater evaluated by their professional, Romero. Romero provided options for its replacement and was available to do so immediately, but I had questions regarding the best financial option for me, a recent widow. The office staff offered me an opportunity to speak with the owner, Scott Duncan. He educated me on water heaters, provided his professional advice, and backed up his recommendations by honoring a Yellow Page Voucher from 2012, and giving me a Widow Discount! Romero was scheduled to return to do the job at their first available time. Romero came back with Zach to help him with moving hot water tanks, and used his help to move other stuff around. They worked carefully and methodically together being careful not to damage the washer, dryer or freezer in the immediate vicinity. They followed my request and drilled the two new pipe holes that were required where I wanted them in a less visible area. I am very pleased with Romero’s expertise and excellent work in replacing an old water heater with a new one. It required a lot of extra work in installing it so it meets the code requirements! Thank you Duncan Plumbing! Cheryl
