I would highly recommend this company to anyone looking for a Plummer. I am new to the area and found Marin plumbing online. The owner Brian is local and shared some great info on Novato. He was professional, knowledgeable and detail oriented. Moreover price is fair and his service is exceptional.

Brian is a real professional, honest, efficient, truly committed to excellent customer service. I highly recommend him. He handles everything himself so he is accountable, and doesn't carry overhead other companies do.

Brian works very slow. His initial visit for an hour was $300 just for consulting on replacing gas tank water heater. He then took almost 2.5 hours reviewing and measuring for implementing tankless gas water heater and charged me $500 plus. Brian then told me that installing a tankless will cost 8k to 14k and that he needed at least half the amount ($5k) as a deposit before he can begin working on the project. He said that by law he can only ask for $1k for deposit but he did not want to proceed with my project without a $5k upfront fee. He then still demanded $500 for his assessment.

Bottomline, I gave Brian $800+ for just a lot of talk and issues on my old house.

My takeaway: Brian is slow and expensive. Give him at most 15min to provide an estimate. He will give you an orientation, show you his credentials, his licenses and insurance, etc but the time spent is money out the door.

I made a critical mistake of giving him options to consider and he spent 4 hours deciding between tank or tankless. 4 hours x $200 = $800. In fact, Brian took 2.5 hours figuring out where to install tankless water heater...

We have used Brian with Marin Plumbing twice and have been very satisfied. He is responsive, friendly and professional. His work has been excellent.

Brian is just the kind of professional that I love to work with. He's very, very timely in his communications, which is very much appreciated these days because that is so rare. He always shows up at the time he says he will be there. We did a bathroom remodel and Brian did the rough-in plumbing valves and then at the end of the job came back and put in the shower and sink fixtures and a Toto toilet. If you've ever installed a Toto toilet, you know that it is a pain in the butt. Brian did an awesome job with everything. I'm very happy to call Brian whenever I need a plumber and I'm very happy to refer him to anybody because he is very competent and has excellent communication skills. Thanks, Brian!!

Our gardener lacerated a copper pipe leading to the sprinkler system and insisted on fixing it himself. It didn't work and he wound up clogging whole system with copper and solder shavings left inside the pipe. Brian trouble shot the problem patiently and efficiently while explaining the whole process as he worked. My gardener showed up in the middle of the process claiming that it wasn't his fault. Brian carefully and with neutral bias talked him down patiently explaining the problem and the probability of where the clog in the system originated. Brian's professionalism and willingness to discuss possible reasons for the system failure over the phone is what prompted me to choose him in the first place. He is fully equipped, prompt, clean, and communicates well: a rare class act.

Brian at Marin Plumber turned out to a be a furtuitous find. After seeing his truck down the street at a neighbors, I decided to give him a call to fix a few minor plumbing issuies which were listed in my home owners inspection report (after buying a home in Petaluma).

At first I was surprised to find out he charged for his time to do an estimate; however, his professional manner and level of skill / expertise was clear. Plumbers can be an interesting bunch and I only want quality folks working in my home / around the family. Brian is the honest hard-working professional you'd want around your home.

I gave him a try and he started with resealing a toilet. I thought I'd start there and based on his performance continue elsewhere. He did an excellent job. Saved me money on stuff I didn't need, and pointed out things that needed to be done. He was VERY fast (good deal for the price per hour), clean, and knowledgeable. I was so impressed I went through the whole house's plumbing. Worth every penny. I learned where all the important shut off switches are, what repairs are worth it or not, and a schedule of when items can be updated (or when they might break). He even knew the failure points in two of my automatic flush toilets; which, can reak havic down the road. I also appreciated all the pointers and items he showed me that I could do on my own time (small home Depot stuff). He also gave me free parts to fix small stuff on my own.

Honestly, I'd encourage everyone to book an hour of his time / expertise and just walk around your home. You'll save a lot of headaches, time, and money with his feedback.

In sum, take a chance! You'll like this guy.

Found Marin Plumbing on Yelp. Brian was the only plumber to call me back out of 6 people I called. He work with my elderly parents and explain everything to them. My mother said he was on time, clean, efficient and very sweet. I also have called him to work on my bathroom toilet. Called me right back, explain everything on the phone in detail on what to expect and how much.

I had a problem with my in-warranty hot water heater this week.
Brian Cooke, owner of Marin Plumbing came out and was highly professional, explained how he worked and assured me he would do his best to either repair or replace the HWH.
After thorough inspection, it turned out not to be my HWH, but a leak in the roof which was dripping into the insulation of the heater.
Instead of walking away, because it isn't his problem, Brian helped me make a plan to have the leak temporarily repaired, time to let the heater dry out and after that, he will come out, inspect and turn on the gas line. I'm in camping mode but Marin Plumbing went above and beyond in service and I know I will be a repeat customer in the future.
Thanks so much for the help and advice.

I've used Brian's Marin Plumbing many times for a variety of plumbing needs over the past at least 10 years. He's always been honest and direct. He's clearly and carefully explained the needed fix, the cost, and likely repair time. He's kept me updated as his work proceeded. He's very polite and takes great care to leave my home spotless when his job is done.

Marin Plumbing is my go-to plumber. A+ service.
