Paul responded to our request almost instantly, was at our home at 9am, and we had a functioning water heater with a new pilot assembly by 9:20am. Paul also noticed the exhaust vent wasn't correctly installed by the previous company and fixed it free of charge, which has brought our gas bill down by over 20%! Their service was priced competitively and communication was excellent throughout the process. Most importantly, they truly care. They took what could have been a nerve-wracking process and made it feel effortless.

I had my water heater break. I had a local plumber come out and he gave me a very high quote and…read moresaid he couldn't just swap out the one I had with a replacement but had to do a major change. I called Excalibur and they said this wasn't true. They could install a similar model of tankless water heater to the one I had. Their quote was almost $2000 less than the other plumber. I since had an HVAC company come out for something else and mentioned I had to change the heater recently. I told him what I paid and he said that was honestly a good price. Excalibur seemed honest and helpful and they were able to come out first thing the next morning and get my heater replaced. They did a good job and the new unit looks better installed than the original. They also gave me advice on how to maintain it and what maintenance I could do myself to descale it etc so it doesn't break again. Overall happy either way the service even though overall it was expensive it was still less than other quotes I got.

My husband went into the crawlspace to look and pipes were leaking under the pressure of a clog somewhere. I called Discount plumbing who sent Antonio out and he arrived on time even though it was a Sunday afternoon. There was no additional call out charge for it being a Sunday and no charge unless work needed to be done. Antonio spent time investigating our sewer line which was completely blocked with roots and partially collapsed. Antonio showed us the camera footage as he investigated. He also went into the crawlspace to confirm what my husband had seen. Antonio was so personable throughout and very clear in his explanation of what was going on and what work needed to be done to fix everything. He returned with a full crew the following day at 8am who put in a 13hr+ day to replace all the damaged pipes in our crawlspace and replace the sewer line. They wouldn't leave until they had replaced our lawn and put our deck back together, working in the dark. Given we initially thought we would have to move out of the house while we waited for work to be done, this was an amazing service.

Outstanding Experience with Fast Response Plumbing…read more I contacted seven different companies to get estimates for replacing my sewer line and house trap, and from the very first conversation with Tim, I had a great feeling about Fast Response Plumbing. After speaking with him and researching reviews on Yelp, it became clear that this is one of the top plumbing companies in San Francisco for this type of work. Not only were their prices competitive, but I also saved thousands of dollars compared to some of the other estimates I received. Customer feedback played a major role in my decision. While a few other companies on Yelp appeared to have similar ratings at first glance, a closer inspection revealed many reviews (sometimes hundreds) were filtered or removed and not counted. That raised concerns about the authenticity of their ratings. In contrast, Fast Response Plumbing's reviews appeared genuine and consistent, which gave me even more confidence in choosing them. I'm extremely happy with the results. Every aspect of the project exceeded my expectations: * Competitive and fair pricing * Excellent communication throughout the entire process * Smooth permit handling with no issues * Expert concrete restoration after the excavation work * Outstanding craftsmanship and attention to detail One thing that particularly impressed me was that they installed a 5-inch sewer trap instead of simply replacing the existing 4-inch trap. That thoughtful upgrade will make any future servicing much easier and demonstrates their commitment to doing the job right rather than just meeting the minimum requirements. They also made payment easy by allowing online credit card payments, which was a nice convenience. Honestly, I struggle to think of anything they could have done better. From start to finish, the team was professional, responsive, skilled, and genuinely committed to delivering quality work. They went above and beyond every step of the way. If you're looking for a trustworthy plumbing company in San Francisco for sewer line or house trap replacement, I highly recommend Fast Response Plumbing. Thank you to Tim and the entire team for a job exceptionally well done!

Hired Water Heaters Only to replace a water heater in Hayward. Often the truest test of a quality…read morebusiness is how they perform when things do not go well. In my case, I have quite a story of having to go five days without hot water because the unit I received was defective. The day after the install we found the tank had shut down. After a reset and restart done over the phone with the installer assisting, the unit failed again, a short time later. The next day which was a Saturday, another technician came out to swap out a heat sensor which appeared to be the problem. While changing out the part, the tech noticed that insulation near the assembly had burned, and ash was present. He vacuumed it out and restarted the unit. It made a horrible noise, and he spent a half an hour on the phone with the manufacturer tech support trying to diagnose the problem. The noise eventually went away and he finished the repair. Unfortunately the machine shut down again after we got one warm shower. I called on Sunday, and explained that I was no longer comfortable with the unit being in our house and I wanted a replacement, of a different maker. Without hesitation they agreed, and Monday morning, after acquiring a, more expensive model of a different make from a supplier, we got a replacement installed, at no additional cost. These problems are rare, and not the fault of the installer. I could not have asked for a more timely and considerate treatment as a valued customer of this business.

UPDATE: Following my…read moreoriginal post, General Manager David reached out early the next morning to understand what went wrong. He promptly dispatched a supervisor, Steve, to inspect the unit. Steve went above and beyond from the start, successfully reigniting the failed water heater and troubleshooting the permit issue. The inspection issue was due to the local code requiring runoff to be routed outside rather than into the crawl space. Wanting to avoid drilling through my front porch, Steve proposed using a workaround device (FloodStop or Watts 210) and proactively reached out to the city inspector for approval. Once the inspector confirmed that a Watts 210 valve met code, David coordinated a return visit for Steve to replace the unit with a Bradford White model and install the approved valve. Steve did a beautiful job with the new installation, expertly redoing the piping and leaving the indoor cabinet completely clean. Best of all, I can finally take a hot shower without worrying that the water heater is going to die on me! I want to extend a sincere thank you to David for listening to my concerns and focusing on a real solution, and to Steve for his outstanding expertise, proactive communication with the city, and top-notch craftsmanship. All the fixes, including additional parts and labor, were provided at no extra charge. While the initial experience was stressful, the management team truly stepped up to make things right.

We used this company in July of 2026 and they were great. We had been smelling a slight gas smell…read morein our garage for a number of months. The smell was not consistent. It only occurred when the weather was hot. Basically, only summer afternoons. We had PG&E come out repeatedly and they could not find the source. We spoke with plumbers and other heater repair companies. All of them told us that it was not our heater; that we were wrong about the inconsistency of the smell. That gas leaks are only consistent and would not happen only when it was hot. We were told that we must be wrong. We felt like we were going crazy. Until we called Bay Area Water Heaters and Dave came out (with a whole crew). He took the time to inspect our heater and said yes, this slight gas smell on hot days is something he had heard of. It was likely due to an old valve within the control panel. He walked us through our options but ultimately suggested replacing the entire heater. His team was able to do the job right then and there and at a reasonable rate. It was completed within the hour. And sure enough, no more gas smell in our garage. Dave and his team were amazing and incredibly professional. We will be using this company again.
