Great guy and excellent service

Erick came out on a Sunday. We were grateful Duncan Plumbing could come out on a Sunday. However, the costs were rather high as Duncan plumbing charges by the job and not an hourly rate and they did tell us in advance what our Sunday "call out " charge would be before we asked them to come to our house. We can't say enough about the plumber "Erick". He was great. Very friendly, courteous, and really nice to deal with. He wore his covid mask and shoe booties while in our home. It took him less than an hour to repair an exterior broken pipe bib and replace a bathroom faucet. We were very happy with what he did for us.

Used Eric for all our home plumbing. Great service, quality workmanship and just a nice guy. I pay the extra travel fee as I know the job will be done right.

Kitchen Overflow During an Event

The crew came out on short notice and fixed the clogged drain of our "commercial kitchen." The crew was well informed, fast working, and super polite. I highly recommend giving this company a call if you need help.

Excellent service with the homeowners concerns as a priorty

I am a do it - fix it all homeowner. I found my self in a plumbing situation that required a sewer line inspection, that I am not able to perform. I called Duncan Plumping and my concerns were noted and a at home meeting was scheduled. I was greeted at my home with 2 very professional plumbing professionals (Eric and Sergio). They were able to use camera equipment to pinpoint the exact cause of the problem and assure me that the rest of my plumbing system was in good working order. This was a relief to find out this information and is saving me a lot of work on my end. Duncan Plumbing has updated equipment and the knowledge that exceeded my needs. I am recommending Duncan Plumbing Plumbing to others.

Eric & Cal Radiant Review

We have used Cal Radiant for a number of years, both for yearly maintenance, troubleshooting and new design. Eric has been 'the guy' in all of these works. He is careful, knowledgeable and fun to work with. I can unreservedly recommend both Eric and the firm.

First rate service, a bit pricey for the task. But thanks!

Prompt, Saturday and I was warned ahead of time on the premium, somewhat simple fix with hole already dug out, tech.went for higher gauge material which I appreciated, water was already shutoff. iPad charging technique and approval signage was first rate.
