Had a fantastic experience working with Excalibur. The pilot light on our water heater went out at 9pm 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. read more

I had my water heater break. I had a local plumber come out and he gave me a very high quote and said 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. read more

Paul was great! Our water heater broke Friday night and we had a new one installed the next day by 11am. Great communication. Would definitely use again. read more

I recently hired Excalibur to replace a dying 17-year-old tankless water heater. They were responsive, courteous, professional, patient, and very affordable (that is, the lowest quote). Now I have a new tankless water heater and I have hot water at all hours again! Assuming they did a good job, I probably won't need to see Excalibur again for a while. But if I ever move to another residence on the Peninsula that needs water heater work, I will definitely keep Excalibur in mind. read more

Really, really fast response time!! Super professional from explanations to accurate diagnostics! Within 30 minutes, they diagnosed the issue and deemed it to be a full water heater replacement. Water leaking from the bottom of the tank and condensation from the exhaust pipe. The exhaust pipe wacky grade (+/-/+) caused the water heater to have a short life because it wasn't venting correctly. Within 1 hour, they were onsite. Within another hour, the technician replaced the water heater as well as fixed the exhaust pipe connections and grade. read more

Alex did a fantastic job replacing our hot water heaters and setting up a recirculation pump and two expansion tanks. Paul walked me through my options beforehand and helped me understand what would serve my needs best. I'd recommend their service to anyone! read more

Excalibur Water Heaters - Water Heater Installation/Repair Near Me

This review is overdue by a year. Paul did a great job fixing my water heater that was making a loud intermittent rumbling noise that can be heard from the second floor of my house. He came on time and even had a brand new burner assembly for my specific water heater that he was able to replace which saved me from having to replace the entire water heater system. Paul was very knowledgeable, skillful, efficient, and provided fair pricing. read more

I was given Paul's phone number by a friend. I texted him about replacing my heater. Within an hour he asked for the photos. He then gave me an estimate and said that they will be able to install it the next morning. The next morning, Alex showed up on time, told me the work will take an hour, and an hour later texted me that all was done. The whole experience was like a well oiled machine. They are true professionals, reasonable priced, and should be an example to other customer oriented businesses. read more

Best trustful and helpful crew at Excaliber Plumbing! Reasonable prices and very informative plumbers. I love these guys!

These guys overdelivered on expectations - incredible service and responsiveness! I was in a bind with a problem I couldn't figure out how to fix, Paul went out of his way on a Sunday, his day off, to move mountains, get me the part I needed, and guided me through how to fix it. They're all about helping their customers and delivering results. I'll be a loyal customer for life. read more

Anthony was very responsive during the quoting process, patiently answering all of the questions from me and my HOA. They replaced two tank water heaters in two different apartments with new tankless water heaters on the same day, and accommodated us with a solution to a tricky exhaust pipe situation. The installation crew was polite, informative, and dedicated to making sure hot water service was restored the same day. Not only does their work appear visually neat, but they also cleaned up the work area very well. Some time is needed to fully evaluate the install and equipment, but as of now, I'm very happy with the work. read more

Excalibur to the rescue again! Needed a water heater replacement after our current one blew out. Excalibur was able to schedule us promptly (mind you during the Christmas holiday week) and gave us a fair estimate. This is the second time we've used Excalibur as they previously replaced a water heater for the other unit in our building in 2018. Still the same outstanding, prompt, courteous and very clean water heater service -- all at a great value! I can't recommend them enough! read more

Excalibur Water Heaters - Our twin water heaters both serviced by Paul! 2018 and 2024! - Water Heater Installation/Repair Near Me

I had a tricky gas-based water heater set up in our condo. An old water heater located deep in our unit that I wanted to remove and relocate due to gas smells and wanting to use the valuable interior space for storage. We spoke to 3 other water heater outfits to try and figure out what our options were (tank vs. tankless, etc...) and none of them could offer a better solution. I almost gave up. Excalibur was my 4th and final call and I could immediately tell when speaking with Anthony on the estimate call through the questions he asked that his company was built upon a totally different level of service and capability compared to the others. This was validated when he visited and reviewed the options on site. In summary, they cleverly installed a heat pump water heater system in the garage and expertly routed copper pipes underneath my building to get the hot water efficiently to all the rooms needing it. Really great job by Andrew and the onsite crew. And all done in just a couple of days. If you're looking for top notch work, you've found the right team. read more

Everything you could want in a water heater repair company. Responded right away, sent someone the next morning, quick honest repair, reasonable price, communicated well, everything was great! read more

These guys helped me out when we had a water heater issue come up a few days before Christmas that needed immediate attention. They were able to help and send someone over the day we needed them, which I greatly appreciated. Good communication over phone, text, and email. Nice guys and knowledgeable service. Pricing was aligned with the other local quotes we got. read more

Excalibur offered competitive pricing and Anthony was very responsive during the quote process. He patiently answered my questions as I wavered between different tankless brands. Ultimately I went with the Navien NPE-240A2 with a crossover valve recirculation setup. It was reassuring to hear that all their technicians are certified by Navien and Anthony was personally involved in the testing of that model. The installation was done by Andrew, who was knowledgeable and professional. He explained everything he was going to do and highlighted areas that were improvements over my old setup. While testing the hot water, Andrew also cleaned out my faucet and shower aerators which markedly improved the flow. 5 star service all around. read more

This is a great company; a good friend recommended this company. Alex came earlier than the scheduled time. I was at Church when they texted me, but he waited. He worked right away. Antonio came and both worked diligently and precisely. They know what they are doing and answered my questions patiently. Great worker. The owner also gives a discount. I highly recommend them. Double 5! read more

Alex from Excalibur communicated his arrival time, which I really appreciated, and the installation was fast and easy.

Excalibur installed a water heater for me a few years ago, and when a part recently failed, they came out within just a few hours to fix it. They replaced the part quickly and only charged me for the time--it was more than fair. Fast, reliable, and honest service. Highly recommend. read more

Excalibur is the absolute best for water heaters. Look no further than them. Call them and get these pros to take care of everything fast. Reasonably priced. Excellent communication. In and out leaving no trace. And very friendly guys. What more can you ask for? The best! read more

These guys know so much about water heaters that water heater manufacturers pay attention to their complaints and suggestions for design modifications. I called up Excalibur once a few years back for a water heater whose pilot kept blowing out. The guy traced it to such an obscure perforation in the drum that I don't think I'd ever have found it even if I'd been looking for it. I called them back recently to repair a different water heater - just as prompt, professional, and courteous as the first time. read more

Honest, Professional, and Highly Skilled! Paul helped us resolve an issue with our tankless water heater after others misdiagnosed the problem and suggested costly repairs. Their expertise and straightforward approach stood out--they quickly identified the issue and provided clear guidance, saving us unnecessary stress and expense. If you're looking for a knowledgeable and trustworthy plumber, Paul is the one to call. Highly recommended! read more

My water heater's pressure release valve was dripping and Paul appeared 10 minutes after calling Excalibur (he was in the neighborhood and offered to take a look at it). After assessing the situation, he luckily had a replacement valve in his truck and swapped it right out. Drip fixed! Price was in line with what I'd expect for a plumbing service call in SF. Speedy, polite, efficient five star service! read more

Perfect service Paul was really helpful answering any questions super clean and fast service I have not water in no time

Quick response via phone and text, quick installation and service, professional. I'm glad I found Excalibur through their reviews.

The hot water coming out of my two-year old Navien outdoor tankless water heater wasn't producing as much hot water as it did in the past. Excalibur came quickly & repaired the heater by replacing a part for a very reasonable cost. They were very knowledgeable and professional. When I asked if they thought I needed yearly inspections, they said every two years would be fine. I will definitely be calling them in the future. read more

Water heater stopped working and I sent out a Yelp request for repair estimate. I had included pictures of the error code displayed by the heater. Anthony immediately called me and told me what he thought was the most likely cause based on the error code, and talked me through "fixing" it on the spot- basically needed to clean the vent which was clogged with lint from the dryer. Heater turned on after and has been working fine since. We didn't have to pay for an expensive "diagnostic test" by a plumber which would have cost about $200 alone not including the actual repair. Cannot thank Anthony enough for quick call, very accurate and helpful instructions, and most importantly 1) being knowledgeable about the heater to predict what was the mostly likely cause and 2) having the honesty and integrity of solving the problem for us for free instead of coming out and charging us for a 'diagnostic test' and repair which he probably could have gotten away with (like the other plumber who was actually there who was telling us we need to pay him for the diagnostic test.) If we ever have any plumbing issues in the future, I know who I'll be contacting! Thanks Anthony! read more

I had a great experience with Excalibur! Anthony walked me through the process of diagnosing the issue with my water heater and quickly identified the problem. Alex came out the next morning, on time and with the right parts in hand; 15 minutes later, my water heater was working again. If your water heater needs repairs, I wouldn't hesitate to recommend Excalibur. read more

These guys are great, very responsive and knowledgeable. Paul and Alex both listened carefully to my needs, and worked with me over several weeks to first fix my existing water heater and then replace it with a new one supplied free of charge by the heater manufacturer (Navien). Their help was invaluable to a) diagnose my issue, and b) seek a manufacturer solution which saved me money. Their pricing is fair (not cheap) but you get what you pay for! read more

My water heater had been leaking for a day so I called around quoting for a replacement. As I was collecting quotes, I realized the price to replace my old water with a standard tank was still going to be pricey. So I called those same companies and asked about tankless and was very happy with the pricing. I had been thinking of going tankless for months once I needed to, and now was the time! In the end I chose, Excalibur and I'm so glad I did! They were in and out in about half a day. Removed the old water heater and cleaned up! The other two companies were worried about extra costs due to repiping and some other crazy things due to my small space, but not Excalibur. They had no issues. Not even a question for them. Again, I'm and out! Please go with Excalibur! Thank you all again!!!! read more

Excalibur Water Heaters - Water Heater Installation/Repair Near Me

So.....water heater broke past midnight. With the help of Yelp I looked up Water heater replacement. A few businesses populated up, I read reviews and started making calls / emails in the morning. I contacted 3 locations and received prompt return calls. Picture & serial# was needed. The first 2 came for estimate and gave me price quote. (Not within my budget). Then last (Excalibur) just gave a more reasonal price quote from Picture / serial number. So they came next day, then realized a pipe needed to be replaced. Of course there's a charge for that. But all in all they charged me a price thats w/in my budget. Can't complain and happyb w/ results. read more

Wow. I'm immensely grateful for the expertise, patience, and care provided when my water heater stopped working. I run a restaurant, and hot water is not a nice-to-have; it's critical and required for me to be open and operate. My call was returned within a few short minutes, and I immediately had incredible confidence. Bottom line: they know their stuff. They got be back up and running quickly. I definitely recommend them wholeheartedly and will be using them for all future water heater needs. Thank you, Excalibur! read more

Super quick response and replaced water heater same day. Totally came through in an urgent situation when my water heater failed and partially flooded the garage floor. I sent a couple photos and they could accurately assess the situation and what was needed. Took time to explain things. I had a straightforward situation with the water heater on ground floor inside garage with easy access. The top floor sink and shower pressure did t return to normal after the water heater replacement - they came back out free of charge right away to take a look and diagnosed that the faucet fixture and spray head had clogged up - they were all old. I replaced the faucet and everything worked great, even better than before - I didn't know until then that the weak water pressure in the top floor bathroom had been due to the faucets all this time. read more

I'm glad I connected with Paul about replacing our deceased water heater. He charged us less than half of what a big emergency plumbing company quoted, he came up with a solution that saves a lot of space in our small house, and he was great with communication. He even spoke with our electricians three times on a holiday to make sure everything worked out. read more

Paul was very responsive, friendly, and knowledgeable. Their quote was very competitive as well.

Leaving an updated review because of Paul and team's continued great service. We had a hot water heater that I couldn't get the pilot lit on, and Paul was able dispatch someone within 20 minutes on a weekday morning to help me out. Would wholeheartedly endorse, yet again! read more

Take a noon run, come home to shower, and realize then at 1pm that there is no hot water when I went to take a shower after my noon run. Start to panic a bit because we have kids laundry to do today plus two toddlers and a wife that all take showers after 7pm. I try to fix the pilot light myself but it's not holding. Crap. Have a work call to do and then at 2pm I call Excalibur after finding them here on Yelp. Paul picks up right away, asks a bunch of questions (like, he is showing genuine interest to help right from the jump), and asks me to text him pictures. I do and he calls me and says "I happen to be at the shop and I can fix this and get the parts here. I can be there in 30 minutes. What? 30 minutes? Not 3 hours, not 3 days -- THIRTY MINUTES. Honestly, I didn't really believe it. 30 minutes later, boom, Paul is here. 15 minutes later he is done with the work. It's now only 3pm! I test the hot water 30 min later as he suggests and all is working well. So let's summarize this: - Picks up the call, has a "eager to help" attitude - Comes to my home in blazing speed - Fixes it quickly and efficiently (- Notice problem at 1pm, call Paul at 2pm, it's literally fixed by 3pm) - Charges a reasonable price. Even thought out second water heater (which was next to the right of the one that failed) had a leak and showed me why he had that concern. Oh great, another vendor trying to tack on charges, right? Nope, he checked it, said his guess was wrong and it just needed some tightening, all is good, no charge for it. Literally as good as it gets, 5 stars bar none. I wouldn't even bother to call anyone else for water heater needs. Thanks so much Excalibur! read more

Apparently there is more than owner of this business. Names won't be mentioned to protect privacy, but they know who they are. One was very responsive and quire friendly (hence the 2nd star). It was the "other" owner who f'd up and lost a potential customer. It's never a good day when you need a plumber, right? In my case, my hot water tank decided to crap out in the middle of the night and flood my garage. During a cold snap. What's worse, my water heater also supplies heat to my home (hydronic heating). I'd always intended to replace the tank with a tankless unit, & lucky for me, my neighbors recently had it done! So of course I asked who did their installation. When I called Excalibur, I mentioned my neighbor"s home & a possible quote to save them a trip out since it would be nearly identical. The "friendly" owner said it was most likely the other owner who did the installation because of his knowledge of tankless units combined with hydronic heating. He'd also mentioned they were busy and it might be a couple days before it could be installed. So he gave me the other guy's number. I immediately called and left a message. (Remember - cold snap + no heat + no hot water) Well, owner #2 didn't call me back that day. Or the next. Or the next. So knowing they were busy, I gave him 48 hours to return my call. Mind you, to have a tankless heater in these units is very rare. To my knowledge, only one other person has one in his unit & the company who installed it closed during Covid. So I really wanted someone I *knew* who was knowledgeable, rather than have multiple people come over to check it out. I wanted heat & I wanted it yesterday! When I called owner #1 & said I'd never heard back from his co-owner, he seemed shocked, told me to call again immediately, & that he'd text him as well. I actually never spoke with #2. He solely communicated via text. The price was massive. I asked about other options (smaller unit - he advised not to). The price to install a *tank* that was HALF the size of my previous one wasn't much less expensive. I remember I had a plumber fix the pump in my hydronic heater a couple years ago & actually had him take a look at my neighbor's unit to see if it was something he could do when the time came. He'd mentioned he was surprised to see what they'd done & it wasn't exactly up to code. I didn't ask how - I knew I couldn't afford it anyway at the time. Long story long - I found another company to install the *exact* same unit, right down to the mixer valve & expansion tank, for the same cost as Excalibur would've charged for a SMALL TANK!! So maybe this should be a 4 star review, because, had #2 got off his a$$ & returned a call, I wouldn't have had the time to look for someone else & saved a bunch of money! Oh, the "up to code" thing was a part where the condensate goes through to lower the PH before going down the drain. Also, Excalibur installed a $100 wired "remote" 1 foot from the unit. It does the *exact* same thing that the front of the unit does. It's great if it were in the house, but 1 foot away (in the garage) is $100 + labor down the drain. (Look at me & my puns!) The point is, I'm sure Excalibur does fine work. But why would you pay a pretty penny for it, with unnecessary add-ons, when you can get the exact same unit/work for much (MUCH) less? read more

Very fast response. Didn't have to wait long for the appt. The person that came was very professional and was quick. He made sure everything was working before he left. What else can you ask for. read more
