Recommended Customer Reviews

We needed a drain cleared. The companies that are specific to drain clearing offered a free quote on site but would not give charge information in advance. Peterson was clear about their fees and also about their commtiment to making sure we would be happy. Someone was sent out immediately and the work was completed in less than 1 hour. They deserve all of the great reviews

Best plumbing experience...I called after reading all the reviews and within 4 hours my drains were unclogged and everything is perfect....Juan and Tyler were very nice and made me feel comfortable...after a few bad experiences with plumbers, they set the expectation, delivered as promised and I got charged a fair price for a job well done.....thanks again Juan and Tyler, I now have a plumber I can trust !

great experiences with the installation of:
steam shower.
tankless hot water-heater.
filtration system.

Easy breezy nice experience. They fixed my faucet. Were prompt and nice. Great experience. I've had them do other work at my home but had never given them a review before. They are my go-to guys when I have a plumbing problem.

We had an emergency situation with water leaking through the ceiling from upstairs. Taylor was really pleasant and clear on the phone re: pricing and told me a bit about his business. Sent 2 guys out who took care of the issue in under an hour and offered to fix or look at any other plumbing issues since they had extra time. Will definitely use call them and/or recommend for any plumbing issues.

Fabulous! Taylor and his crew, for my repair it was Daniel and Brian, are the best! You would have thought that I was Taylor's only customer. He was patient in explaining how they were going to make my repair and right off the bat, said, ""Michelle if you have any questions, don't like the way the work is being done, or anything, please call me."" I needed a new water line run from my meter to the house. Brian was here digging the trench and was very pleasant to work with and then Daniel came out and laid the pipe. Daniel did beautiful and very professional work. Absolutely no complaints about anything. Don't hesitate for a minute in calling Petersen Plumbing Services!

We had backup in our showers/tub in the house (ewey!) and the very nice Plumber we had used previously had vaporized - so I hurriedly looked at YELP to help find a new one.
When crap is flowing back into your house, you don't take a whole lot of time to decide - you find one local and available - but, it was re-assuring to see 5 star rating for Petersen Plumbing here.
Right off, Taylor Petersen makes it known that he's local in the Mill Valley community and that he wants to be your plumber now and forever more and promises good service. I like it when a businessperson makes things plain and sticks his neck out on the service angle particularly in a service industry like Plumbing.
He promised that by day end someone would be over and indeed about 5:30PM someone was. They pumped the sludge from the house and determined that the rest was Sewer authority oversight. The Plumber sent (actually a team of two really decent chaps) stayed on the phone for 30 minutes to find the right sewer district and make them aware of this emergency.
To everyone's credit, the sewer authority was there in 2 hours....but, determined that it was the house line, not the public sewer line at issue.
At around 8:30PM (PM, mind you!!) Mr. Petersen called back to say that a plumber would be out shortly to take care of the pumping. At 10PM (10PM!!) one of the two earlier plumbers came back, pumped a few times and all was right in our plumbing again.
Yes, one could be cynical and say that the original call that it was the sewer authority at issue was in error, but honestly, I'm no plumber and I do not know how difficult it is to determine these matters (especially at night). The fact was that within the same day, this plumber (who had probably started work at 8AM that day) was at my house at 10PM(!) taking care of what they do. I KNOW the poor chap was tired, but a smile never failed to purse his lips and he was totally professional about it.
These guys earned our loyalty and future business. It was a pretty determined display that Mr. Petersen meant every word he said about caring for his customers. Deeds done matched the high standard set by his own words earlier that morning.
Good show, gents!

Ron came out today and fixed what we needed - so nice and didn't waste any time. Taylor was great on the phone, too. Will hire them again!

I never write reviews, however, this company shouldn't go unnoticed. I called on a Monday to many plumbers, hoping one would be available to see me that day. It wasn't an emergency, but I did want someone out soon. Everyone was busy and told me that they couldn't come, or they might have time to come at the end of the day. Only Peterson called me back out of 5 others that told me they were possibly available later that day. He apologized, but it was getting late and his employee was not going to be able to come because he was still on a job and was covered in sewage. Since he was the only one who bothered to call and tell me, I asked if someone could come in the morning. He sent this most incredible person. Professional, courteous, knowlegeable. He identified the problem, told me that he didn't have the part, but that he would go get it now, and I wouldn't be charged for the time he was gone. He came back promptly, fixed the problem and showed me a couple of things that I didn't know about the plumbing under my sink. Nothing that was wrong, rather just useful info. When I was handed the bill I was even more surprised. It was so reasonable. He charged me the minimum 1 hour. I almost cried! I have never been treated this fairly by a plumber in all my years of experiences. I will refer this company to all of my friends, especially the women I know who have struggled to find someone who doesn't take advantage of there lack of knowledge about plumbing!

Yesterday, we discovered that we had a pinhole leak in the copper pipe of our upstairs shower drain.
Today, I did a search on Yelp and found Petersen Plumbing. Though it was a really busy day for them, Tyler Petersen, owner was nice enough to free up someone to come over to see if they could do the repair today.
Brian, took a look a my problem, and was able to fix it. He did the repair quickly, and I would recommend and use them again.
The base rate is $148 per hour, and after that, they charge in 30 minute increments.
Though the work was done efficiently, I was a bit surprised that Brian did not have the necessary parts on his truck to do the type of repair I described in my initial phone call. So, he had to return to the shop a couple of times to pick up the parts he needed. Fortunately, the shop was close by. Unfortunately, I was charged for his travel time back and forth. I figure that added an additional 30 minutes to 1 hour ($74 to $148) to my bill.
As I said, overall I'm happy. I appreciate that they were able to fix my problem the same day.
One last thing. I was told if I were to have used my credit card to pay the bill, I would have been charged an extra 5% (because that's what the credit card company charged them). Brian told me they accepted cash or check. The owner should look into using Square as they only charge 2.75% to process a credit card.
