Marc is a super hero!!! I had a Water Heater that blew out and Marc showed up same day. He is semi-retired meaning he can help anytime and he is a blessing. I am in Real Estate and have spent decades with Plumbers who don't show and take advantage of people. Marc is a god-send to homeowners in Lafayette and Orinda. He is a neighbor and now a friend. I have a 4 year old and 6 year old clogging toilets with TP and Marc recommended these newer toilets and it has been a game-changer. Rather than coming home to clogged toilets, I come home to a happy family. I cannot recommend him highly enough. 6 Stars!!! out of 5!!! read more

My house was built in 1954 and I needed a shut off valve installed from the water line to the ice cube maker in the refrigerator. Marc came out and did a super job of installing this valve in the wall behind the refrigerator. He is very knowledgeable and very experienced and I highly recommend using Marc. read more

Honesty is everything in the service industry when one is looking for a reliable technician. That, of course, includes getting the job done right. Marc Brenner is one of those guys. After interviewing four different plumbers, Brenner not only made the most sense in how he would approach my job but he offered the lowest price. And he did an excellent job, coming up with a creative solution to a tricky pipe leak. . And, it turns out he's my neighbor, which didn't hurt. Good guy. Highly recommended. read more

I have used Marc twice to install forced air heating into old houses that had only a floor furnace and all I can say is wow. I absolutely love this guy! I wish all contractors were as honest, skilled and knowledgeable as he is. I would not hesitate to recommend him to anyone. read more

Marc was a lifesaver for my leaking grohe faucet. He was quick to reply to me upon my initial inquiry and has excellent communication and customer service! He let me know when he would be there, set a price before hand and was reliable through and through. So grateful to have found Marc for this event and all future plumbing needs! He truly is as good as all his 5 star reviews say he is. read more

Marc Brenner is an amazing plumber. He was the back up plumber when my plumber was out of town. My hot water heater died, and I thought it was a simple job to replace it. He said he would do it that day. Then, unbeknown to us, a flood had occured which we did not see due to the water soaking a very heavy wool rug. When Marc found out about this, he did not waste any time figuring out why there was a flood. Instead, he got down to my place immediately with a fan and blowers and even checked out the sheet rock, which was soaked, and then replaced it for free. He was really incredible. If that was not enough, I got an email from him today recommending how to protect against any future floods down there, even if the new hot water heater lasts 10 years! He is highly recommended; very ethical and smart. read more

Marc is the best plumber I've ever known. He has done several major and minor jobs on my house and I have never had any problem. Also, he has gone out of his way to help me when I had plumbing emergencies over the holidays. I wouldn't use anyone else. If he cannot do a particular job (like sewers which are not his specialty) he always refers me to the very best people in the area. read more

Marc Brenner went above and beyond in assisting me with a kitchen repair to the ventilation system. He is trustworthy, patient, responsive and follows through to his utmost ability. He is excellent and I was very pleased with the results. I will definitely choose Marc for my plumbing needs again. read more

Marc installed a new hot water heater and we plan to use him to install a new heater. Marc's a solo practitioner, clearly knows what he's doing, and is a pleasure to work with. He was also cheaper than some of the bigger companies out there. I'd use Marc again in a heartbeat. Strongly recommended. read more

I can't thank Marc enough for the help he gave me in resolving a burst water pipe at my home. Unfortunately, Marc was booked and could not repipe my home; but he guided me through a difficult time with the course I should take in fixing my problem. Because Marc couldn't do the work, I hired a plumber and had many questions along the way. I know if Marc had been available I would have totally relaxed knowing that no short cuts would be taken and that the best job possible would be performed. Marc is a great person and a forensic plumber!! He is the best!!! read more

Marc installed our brand new HVAC system during our extensive remodel and did an excellent job. Even though we live in Oakland, we decided to add central air conditioning while we were at it. Marc worked with our contractor and calculated all the airflows in each room and designed a thoroughly efficient system. During the summer or winter, you hardly know the system is even running and it keeps all the rooms at the selected temperature. I would recommend Marc and his team for everything from the most complex installation to anything else in the plumbing, heating or air conditioning world. read more

Once again, Marc saved my a$$. Old pipes = gas leak = PGE shut down gas = very angry wife. Couldn't get a hold of Marc, and time was of the essence, so called another plumbing company (big mistake) named after the guy on the $100 bill. First they quoted me $13,000 to repipe. Then, after bringing out "the boss" for a final look, told me it would really be $16,000 and they would get it done ASAP. I told them "no" as it seemed like they were taking advantage of the situation and the fact that I was desperate. When I got a hold of Marc and told him the story, he came out immediately to walk the site and figure out a solution. Less than a week later, I have a new gas pipe that PGE is happy with and most importantly, the wife is happy too. Total cost = $10,000. Thanks for saving me $6000 Marc! read more

Marc came the same day I called and arrived on time. He replaced a bathroom faucet fixture that had been leaking. The job presented some challenges regarding access, but Marc persevered. He stuck with it and figured it out with great success. I am very grateful for his determination and a job well done. I will be calling on Marc in the future and highly recommend his expertise. read more

Marc talked me through lighting my pilot light on the phone for no charge. He facetimed with me and we got it lit. Such a great person! I really can't thank him enough!! read more

Marc was amazing. He is diligent, trustworthy, responsible and a pleasure to deal with, even in difficult circumstances. We had a tricky leak at a rental property, so I wasn't even on-site. But he went over and above what I would expect from any repair person. I would definitely use him again and would highly recommend him. read more

We have used Marc Brenner for our plumbing needs for years in our rental property and in our own home. It is not easy to find a plumber who knows what they are doing and who is also honest and fair. Marc is both of these and more. He does high quality work, is very responsible, and backs up his work. I cannot recommend him more highly. We have recommended him to several friends and they are always more than pleased with their interactions and the work. He is a great guy and if you need a plumber, you will be fortunate to have Marc work for you. read more

We called Marc because none of the other plumbers on YELP were available for 4 days and Marc said he would come right over. Happiness is finding a plumber who is true to his word, arrives on time and does not overcharge. Our leak required getting a leak detection service who also came quickly and the next day Marc came and repaired our pipes. Honest, dependable and trustworthy. He chose to be a plumber instead of going to law school...what does that tell you? Our water had to be turned off for 30 hours, because it was so cold the cement for the connection would not cure. Oh well...we had fun! Thanks YELP. we have a wonderful plumber! read more

Marc Brenner is simply a great plumber and a kind, decent person. He's friendly, responsive, responsible, informative, and competent. I would recommend him highly. It was a pleasure interacting with him, and am so grateful he was suggested to me by Ashby Lumber. read more

Marc Brenner is hands down the best plumber I've ever used! He is knowledgeable, efficient, on time and very reasonable! In fact his level of service exceeds anyone I've used in the past 10 years! The 2 plumbers that I consulted prior to him ( for a pump replacement on the water heater) one couldn't even tell me what was wrong, and the other didn't get back to me with a quote! Marc came right over, assessed the situation for free, and when the pump arrived was there the same day to install ( after having researched on line to make sure position etc was correct!!) Amazing! Thank you Marc. You are my plumber for life. read more

Thanks for your work under very difficult conditions, Marc. Yor really went the extra mile for us!!

I can not say enough good things about Marc Brenner. He is smart, honest, responsive, and cares about his customers. I interviewed a number of plumbers to install a tankless water heater and Marc came highly recommended. He certainly did not let me down and always made himself available for my 200+ questions without making me feel that I was wasting his time. His follow-up was impeccable when we had issues with the tankless heater provided to him -- he followed up with the company & created a sense of urgency on my behalf. He is thorough and thoughtful and I was impressed with his knowledge base, as well as his willingness to solve difficult issues. read more
