    Had a fantastic experience working with Excalibur. The pilot light on our water heater went out at…read more9pm and was showing no signs of recovery. 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 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.

    Fast Response Plumbing did an incredible job with my sewer line repair in San Francisco. We decided…read moreto get a lot of bids for this project. Theirs came in at a very reasonable rate, and most importantly, they had capacity to start as soon as possible because we had an urgent sewer line failure. When I called, I believe I came into contact with the owner. I explained to him the scope of the job, and I even told him that he probably doesn't need to send a plumber out because, at this point, we are just comparing costs and I even hinted that we were desperate to get started as soon as possible based on what was told to us by the other plumbers that came out. The owner told me that he'd send a plumber out anyway to do their own scope, since other plumbers may have not been consistent, he could have very easily taken advantage of my desperation in this time, but he didn't David was the only plumber out of the many bids we got who actually called us out and showed us what was on the camera, and explained to us what was happening underneath our house. Within 24 hours, he got the quote back to us. Again, he knew it was an emergency, so the turnaround was great! He came out with a nicely staffed crew. Within a few days, our floor was jackhammered, there was a mound of dirt in our garage, and within the next few days, they connected our sewer line, so we were only without water for a few hours at most. The sewer line installation passed city inspection (SF) the first time. the dirt was quickly backfilled, with concrete poured on top. From a little over a week to the initial consultation, we had a perfectly working sewer line, and we were able to park in our driveway. they were very neat after they completed their job, and they even cleaned out our garage where all the backfill dirt was being stored. I highly recommend them for your sewer repairs, and they will be our new plumber going forward.

He was also flexible about waiting for me to confirm that our building's water could be shut off before scheduling the appointment, and he provided an upfront cost estimate that was completely reasonable. The two technicians (Jarvin and Kevin?) who came out kept us informed when they were on their way and were courteous, professional, and efficient in completing the work. We'll definitely call on them for future plumbing needs and wholeheartedly recommend them to anyone looking for reliable, professional service!

Project was clear a clogged bathtub drain, change faucet and s-pipe in powder room. CARLOS arrived within time frame of service, was quick to assess and get to work.

He assessed the situation, offered me options of service. Essentially a quick patch job or replace the pipes completely. Given that the pipes were original with house. Inaction was not an option for the leak either. A patch job would only defer the work further down the line. I like to take care of issues as soon as I can. So I opted to replace the pipes. Groan... CARLOS returned the next morning and set to work right away. I was surprised he didn't have any help but he did an excellent job! CARLOS is well-thought out of what he needs to do, meticulous in plumbing the job and that it's done correctly in minute detail. CARLOS made sure he cleaned up the area, went over the changes with me and while I cannot address the pricing point here. I was very appreciative and glad CARLOS was here and had taken care of the scheduled work, as well as the unfortunate unscheduled work. CARLOS gets FIVE+ stars for himself alone! Definitely reach out to ACE PLUMBING & ROOTER for your next plumbing project. And ask for CARLOS if he's available!

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.

    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.
