Recommended Customer Reviews

I called and asked for an estimate. He gave me one right away. I asked for a time and he could come right away. His estimate was reasonable and his work was good.
Look at his card with a painting called. ""Portrait of the artist as a Plumber"" , on it.

Dan B. Underhill is an amazing plumber and a neat person to talk to!
My bathroom had many years worth of deferred maintenance issues, and a previous plumber, who came very highly recommended by a personal friend, took one look at my bathroom, made up some excuse about ""being called away on an emergency,"" and never returned.
But before that previous plumber left, he had made noises about me having to buy a whole new sink, because he didn't think parts for mine were still available.
So that gives you an idea of the type of situation I presented Mr. Underhill with. Fortunately for me, Dan, with his can-do attitude, got everything fixed. And he never said one word about trying to sell me on a new sink.
The quality of Dan's work is excellent, and his pricing was more than fair.
Best of all, my bathroom is now fully functional, with no leaks and no maintenance issues whatsoever.
I hope Dan lives to be 150, 'cause I don't ever want to use another plumber!

Dan is the top 1A% of plumbers in California. I had a very challenging bathtub drain problem. It was complex and challenging. Massive digging had to be done. The final bill was $8,000. Dan and his team did a great job. Dan is a brillianty conceptual thinker and a wonderful person to work with. In the plumbing business, nobody does it better!

Dan is a truly outstanding person and great professional. I have read about him at Nextdoor and was amazed by his willingness to share his knowledge and experience with a DIY guy like me. Dan's advise allowed me to significantly cut the cost of a large project by doing many things myself and avoiding costly mistakes along the way.
Dan is a very active community member with demeanor and vocabulary of a university professor. I thoroughly enjoyed our conversations and Dan's sense of humor.

Dan is terrific. Was able to do a major gas line repair fixing many leaks and getting PG&E to turn the gas back on for our house. Great work, very conscientious and careful. He has also helped us out several times on plumbing items and been terrific too. When dealing with plumbing and gas lines and without living essentials it can make things very trying. Dan's friendly and engaging spirit make it better and work is outstanding.

There are not enough super things to say about this plumber! I had an emergency -- a nonfunctioning toilet in a one-bathroom home and he responded immediately! It turned out there was mud in the tank of the toilet from work the Water Dept. was doing on the street and he got the pipes roto-rootered so they worked perfectly! I mailed him the receipt later to add an explanation of the Water Department being at the source of the problem, so that I could file a claim with the City for reimbursement, and he wrote a clear explanation on the receipt and mailed it back to me, also instantly. He is good-natured, skilled, and super responsive. Highest recommendation!!

Dan was very responsive to my call in the evening after a failed attempt to hook up a laundry center earlier that day, due to old hook-up water valves that wouldn't turn and so needed to be replaced.
Dan came out promptly the next morning, saw what needed to be done, fetched the parts and replaced them all in under 2 hours.
He was so friendly and engaging and thorough, I wouldn't hesitate calling him again.

We had an emergency plumbing situation come up late on a Friday afternoon. After making numerous phone calls to every plumber in the book, where nobody was able to help us (if they even answered their phones), Dan came and saved the day. He fixed our connector to the water main that evening, and charged a very reasonable price. Would not hesitate to use him again.

He was great.. Unclogged the shower, reasonable rates and personable. Calling again to do another job

Dan was so nice but he was up to his ears and couldn't help me. He gave me 3 other people to try and that is so nice. Dan was recommended to me by Mike at CalStar plumbing and Mike is the person I've used for years but because Mike is hurt he recommended Dan. Dan and I spoke and he is the nicest person, I would totally recommend him.
