Best in San Francisco CA

I received several quotes to have an on demand water heater installed.  I contacted Beastbay Plumbing and Brooks was able to come out the next day to provide me with a competitive quote.  He was conscientious about the needs of my family and didn't try to oversell me with something that I didn't need.  
He was able to do the install in one day and my hot water worries are a thing of the past.  Very satisfied with the service and quality of the workmanship.
The Navien water heater has a terrific reputation and I feel confident that I purchased a great product from a terrific company.
I would definitely recommend Beastbay Plumbing.

Used their services 2x. Spencer (owner) was courteous and helpful. Job well done. I recommend them.

My wife has been doing business with these guys for decades and they have been consistently providing us with great service. We were recently forced, due to a PG&E program, to deal with California Energy and had huge problems with them. When one of the units they put in two years ago went down, we called Tromborg and, once again, they came though for us (clearly no hard feelings on their end). When my wife called late morning they recognized her and said they were very busy but would fit us in between 3PM and 6PM. They got here at 4PM and we were back up and running by 4:30PM (dirty flame sensor - after only 2 years! Not good Trane). We highly recommend them for fast competent, and reasonably prices service.

Advanced Plumbing and Drain were very responsive and helpful from the time I called through the plumber arrival and inspection. We requested some help with our water heater and they were happy to same-day inspection and free diagnostics. They showed up within the pre-specified time window and were able to diagnose and fix our issue within minutes. I offered to pay for the time, but they declined, which was super generous. I would not be hesitant to call them again whenever I have trouble.

These guys are great. They respond fast, and arrive in 1hr (given they are not in the middle of a job).

I called, they arrived in 1 hr, they did a great job. Drain the old water heater, removed it, cleaned the area, create new connections, installed the new water heater, and they did a good job cleaning up after themselves.... reasonable price, not a rip off, honest work.

I recommend...
I will call them again for any plumbing issues....

We had Gregg come out to get a quote on piping a gas line for a fireplace conversion. Gregg was able to come out within a day to assess, then be back within like a week and knock it out in a day. Permits and all. One stop shopping. Gregg and crew were awesome to work with, super friendly and did top notch work. Highly recommend for plumbing renovation needs! Would not hesitate for future work.

I have been using this company for three years to service my boiler and every time things go very very smoothly. In the last six months I've had some things on my boiler that have needed to be repaired and they have been fast, efficient, and customer service is  polite and great with giving me information on what the repairs were. I have never been shocked by their pricing and will continue to use them in the future.

I've had Chung Wah do a variety of plumbing work in my house over the last 8 years. Steve is super knowledgeable and can pinpoint the issue within a few minutes. Most importantly, he's honest and trustworthy.

Any time I've had an emergency, Steve is extremely responsive and takes care of the issue the first time around.

I highly recommend Chung Wah for your any of your plumbing needs.

First, i did not use five star plumbing. I used someone who could get to me faster. Five star could get to me fast, but just not fast enough. I ended up paying a 25% premium for the faster service.

Next time i need plumbing I will give them a call first.

Did a fantastic job replacing an old tankless water heater. Often you're concerned about what you don't know when doing a job like this, Edguardo was patient, professional and did a great job. His price was competitive and he arrived, did the job , cleaned up and was ready to leave. Super happy with this and wild use them again.

Vincent was really thorough when giving us an estimate and the price he gave us was fair compared to others.  He was also very responsive and was able to get started right away.  Overall happy with the result!

These guys have restored my faith in contractors.  I had a nightmare project that lasted years with a ton of complicated issues and delays.  We went through a bunch of contractors over the years who eventually got fed up and abandoned us.

Pete and Lauren are the ONLY people that stuck it out and saw the job through to completion.  They helped sort through a bunch of the DBI and SFFD's confusion and the mess that other contractors left, and they got it done.  I would be in a world of trouble had Pete and Lauren not been patient and professional as they are.   Their work is top notch.

Ronan is a very reliable plumber! He was on another job but was able to stop by within the hour when I had called. Very friendly and trustworthy. The plumbing issue ended up being more complicated and required a rooter, but totally worth having him stop by to help me understand what the issue source was and for being very thorough with his work and recommendations. I would call him again. Thanks very much Ronan.

Professional, friendly, responsive and on time. Gavin is awesome. He does our backflow test every year. Highly recommend him.

We had Excalibur do a complete repiping job on our home in Alameda.  They filed for the permits and got to work within a few days to do the work.  They showed up on time with a good sized crew and worked though to the evening.  All of the major work was completed in that first phase and it was done professionally and efficiently.  They will return in a few days, after some other work is complete, to do the finishing touches.  Their communication has been excellent and we've been nothing but impressed with their work.

Bedr was very helpful and responsive. We had a small job to clean the bathroom fan, and Bedr was prompt, thorough, and excellent.

I have known Bill for over 6 years.  He has done extensive plumbing for the remodeling of our home, including three bathrooms and a gas fireplace.  We have also had him come back for some routine maintenance during this time.  He is honest, efficient, competent and a joy to work with.  His fees are reasonable and he guarantees all the work that he does.  I would not hesitate to recommend him to my friends and family.   Bill gets top praise from me.

Really helpful group of guys at this store that seems to cater to plumbers. I was looking for a specific color and size to replace my kitchen faucet. I went to Home Depot but the clerks don't know anything, even after I waited 15 minutes for the faucet specialist. Ed at WB helped me figure out the most workable answer. Super nice guys and very patient.

Zayah was on time, knowledgeable, asked enough questions to make sure we were on the same page, but was unobtrusive and efficient. He diagnosed Missi ng parts we needed, took a quick trip to the store in my behalf, and replaced our disposal/repaired some broken sink plumbing quickly and cleanly. Strong recommend!

Just got my heater installed.  The estimator, Don, was very knowledgable, and promised us we would be happy with upgrade he recommended.  We are.  The heater is silent and very efficient.  The work is very tidy and the new unit is much smaller than my outdated, asbestos ridden machine.

Definitely will recommend to others.
