Great service

We are always happy with the work we’ve had done by Duncan Plumbing. They are easy to get in touch with, polite, flexible with scheduling, and have competitive pricing. They are also very good about keeping the floors and house clean while they are doing the work and moving equipment through the house, which we really appreciate with our hardwood floors. I can’t say enough good things about this company. We’re very pleased with their service!

Quick, efficient, and solid work

Eric and his team showed up when they said they would, did the work they said they would do, and finished when they said they would. They were friendly and pro-active. They identified and fixed the issue, and left the site clean. All at a very reasonable price. There's not much more that could be said in praise of contractors.

Sink installation

Jorge of Duncan Plumbing arrived at the scheduled time. He had to reconstruct the faucet and replace a very heavy cast iron sink. He completed his work efficiently. He made suggestions to save money and improve efficiency of the kitchen sink.
