Testimonials

 Customer satisfaction is important to us…so when a previous customer takes the time to write a testimonial regarding their satisfaction with us we are extremely humbled and grateful that they chose us.
Can’t recommend these guys enough. For 3 of the 4 issues I’ve had, they’ve talked me through how I can fix myself. A great local business.
David Goldfarb

I needed a plumber for my backflow inspection and I emailed him for an estimate. He was quick to respond and was able to provide a date and time. When that date came, he was even early!! He was very professional and friendly. I highly recommend Durance. I would use them again

I’ve had Durance provide plumbing services on a couple of occasions at various properties that I own. This time I called on Sat about a water pipe and water heater issue at a resale property I bought earlier in the year. They indicated their schedule was packed but would work to fit me in on the upcoming Monday afternoon. They came out as promised and quickly diagnosed the issues. They explained what was going on and offered me some options. Finally they performed all the required/ requested work satisfactorily. Continue to be pleased with their services and personnel.

The guys from Durance (Kirk, Adam, Matt) are honest, knowledgeable, and dependable and do great work. We have an old house and have trusted them with several different jobs (backups, leaks, furnace replacement) — including in the middle of the pandemic. Each time it was a good experience despite the difficulty of dealing with plumbing issues. They’re more interested in building relationships than making a quick buck.
