Thoughtful, fair, and no-nonsense. I had a heating element problem with my cedar tub, and found it was hard to find a team/service that had the expertise in working with the components of a cedar tub. They fixed my problem in one visit with no drama and gave me clarity beforehand on what scenarios to expect as well as a price range for the different scenarios (surprisingly other competitors were aggressively opaque on expectations/pricing, which felt sketchy). read more

Odd/hostile experience working with Dakota and Andrew at Sullivan. There was minor damage to the cover of our hot tub on a service call and instead of accountability, Dakota blamed the age of the cover. It was a strange mix of defensiveness and blame on the call itself. We had an issue with the tub draining after a power outage and Sullivan saying that was impossible unless there is a leak or crack. Ok, well if it is a leak and crack then possibly inspect those areas as a service/repair service? I'm not an expert in hot tubs. We purchased a house that had a new hot tub installed, and the continued response of the hot tub being old for the reason why the damage occurred is weird. The middle part of the cover was also ripped apart from the seams and there was minimal accountability there as well. The new Operations Manager had a weird, defensive response as pictured below. You can be the judge if this is an off response to damages in an inspection and repair. The hot tub after servicing is also still leaking. We needed to hire another local servicer to do this repair work who properly described what might be the issue BEFORE coming out to work on the hot tub. read more

Sullivan Waterworks usually works on hot tubs, but we have them working on our very old spa. Michael came last year for the 1st time and did such a good job we hired Sullivan to come yearly to empty the spa, clean it, and inspect all equipment. This year the jets would come on and then slow to a trickle. Michael was not going to leave until he got them all working correctly. He was here for over 3 hrs. and finally got them all going strong. A big shout out to Michael for his hard work and to Sullivan Waterworks for great customer service. Could not recommend them more highly. read more

Great company! Very honest! I had a really hard time getting someone out to repair the leak on our hot tub. They showed up when they said they would and they made the repair. They also charged is less then what they quoted because the repair turned out to be less extensive. I highly recommend you using this company! Thank you Sullivan Waterworks! read more

My pentair heater stopped working. They came out diagnosed the problem replaced the circuit board with a used one at a reduced cost. Pleasant professional and showed up at the scheduled time. Will definitely use again read more

Michael provided great service. He was on time, knowledgeable, quick and friendly. A wonderful experience!

So competent! Been over a month since hot tub worked. Mike from Sullivan Waterworks finally came yesterday and installed a new heater and other special work...no additional charge. I am so appreciative I finally found them . I might just have an every 8 week service as a result. read more

I was hoping for more. I reached out to Sullivan Waterworks in January, explaining that I've had trouble with my hot tub chemistry (the tub was about 7 years old) and hoping they'd partner with me to get things on track. After each visit, I emailed them that the water turned murky and would they help me trouble shoot. Team members and Sean had contrasting advice on how to solve my issues. After paying a total of $1,000 between drain and refill, replacing the ozonator, and 3 months of monthly service, I gave up. Sullivan replied they could drain and refill again at a reduced cost. After I'd already invested $1K-- the discount amounted to too little, too late. Seems to me they just wanted a routine going through the moves, but not to take me on as a customer with a more complex issue to solve. Disappointing. read more

I have a really old hot tub and Sean and his team have been great in keeping it running. Just recently the tub had a leak, and it was challenging to figure out how to fix. They persisted, came up with a solution after an initial try, were very fair in their pricing, and Micheal did a great job in fixing it.. No more leak. I highly recommend them. read more

I am very happy with the job that Nate did for me. I met once with Sean and he made himself available by phone when I had questions, and I appreciate that. Nate's work was incredibly clean. Their proposal came in at the high end, but what made that worth it was that I didnt have to supervise every step. I told them what I wanted and they got everything done. read more

Nate came out and did an incredible job cleaning/filling as well as explaining how everything in my custom hot tub worked. He was an extremely nice, pleasant and detailed teacher in explaining how to maintain my hot tub going forward. I highly HIGHLY recommend their services. read more

I've had a long history with Sullivan. At first, it was just him and the maintenance was extremely inconsistent. Communication was the same. Then he hired, and the normal maintenance of the tub water was done very well. I can't remember his name, but the guy doing the service was really nice, relaxed and competent. Unlike others in these reviews, my experience with mechanical maintenance done by Sullivan was abysmal. Bad communication, incorrect recommendations, etc. A response you might read will be along the lines of "he didn't pay his bill" - which is true of the last service period because it took me months to get a callback and resolution. They issued an invoice which was being filtered by a system I use to kill various kinds of spam and newsletters, so I didn't see it. Instead of calling to ask about it - months later he *showed up at my house as I was moving out WHICH IS SUPER WEIRD AND CREEPY* So, yeah, I'd pick another vendor. I think the people that work for him are great but Sean Sullivan isn't running his business professionally. read more

So pleased to be able to give an A+ review to Sean and his team, since I've felt like I've not been happy with previous hot tub repair folks. My hot tub died just after the New Year in the depth of the cold and rain. Sean was able to get someone out right away to do a diagnosis: looks like the pump was installed improperly by the last tech and the seal leaked water onto the pump and shorted it out. Since my pump requires a very specific type of pump, this is a very expensive repair, alas. Sean was extremely up front and informative about the costs (and the reason for the costs), got his guys out there as soon as there was a little break in the weather, and had me back up and running quickly. There was a tiny hiccup with the guys leaving a box of leftover materials on my deck -- when I called him, he apologized and came by himself to pick it up. I feel 100% satisfied with everything about the service: the quick responsiveness, the clarity of the communication the customer service focus. Really happy to find this vendor/get to know about Sean and his company! read more

I had a series of very helpful emails with the owner. After I sent pictures, he gave me an estimate that was one third less than the estimate given by another company. Sean and Liam came out promptly, installed a new pump, discussed the whole system with me and offered some ideas for the future. I am completely satisfied, and if I have another problem, I will certainly call Sullivan Waterworks. read more

Since he was out of town and unresponsive to my "heater doesn't work and I am freaking out and can't figure out how any of this stuff works" incident, Sean has been really responsive in helping out with what's a manufacturing issue on the heating element for the hot tub. He seems to have permanently fixed it by hacking it himself, and will soon be installing a Nest-style system so that I can turn on the hot tub from my phone! Yay for the Internet of Things. Also for cedar hot tubs (that heat up reliably). read more

Very impressed with the service level! After initial contact, once Sean knew more about my problem, he directed me to a site with instructions to fix the possible issue. That worked, but then i found a leak so he still needed to come and help. He took care of the leak, replaced my pump which was failing. All timely, great communication, and now all is fixed for a very reasonable price. I wish there were more contractors like him!! read more

Sean is the BEST. He did everything right. He gave us a fair price and great service. He really knows his Hot Tubs and how to fix them. I highly recommend him and his company. He knew how to get the job done and done right. He did not leave until everything was working perfectly. He even cleaned up after himself. He installed a new heater for us. I really appreciate the advice he gave us about the best heater for us. He is knowledgeable and talented. Last but not least- He was super nice and friendly. read more

Went with all the great reviews for Sean and his business and called to set up an appt. His voice mail recording says to contact him by email which I did. He suggested a time and date which I agreed upon but once I requested a simple, general price quote for his time to assess the situation, I never got a reply. His suggested time/date came and went. Hmm... so I emailed him again, stating I wanted to make an appt as soon as he answered my question and never got a reply. I expected to pay a pretty penny for his time and work but I guess he didn't like to answer honestly? Or he thought I was being cheap? Poor business communication if you ask me. Will NOT be using Sullivan Waterworks and will get in touch with someone who wants my business. read more

I called him on March 4th and got his recording that directed you to contact him via e-mail which I did. I left a message saying that our hot tub was not working and that we needed to get it fixed as our house will be shortly put on the market. Now, four days later, no response. So now I have wasted four days waiting for a response. Poor customer service. If you don't want work at least say so in your recording. read more

Sean had some staff reliability problems in the past, all resolved now. Excellent, dependable service read more

We are "elders" living in the Montclair District in the Oakland Hills. We asked Sullivan Water Works to replace an aging backyard deck redwood hot tub we have enjoyed for decades. Dear spouse is a Physical Therapist for whom evening hot tub sessions have been important to maintaining physical health. We knew that a redwood replacement tub was financially unrealistic., Sean suggested "Yellow Alaskan Cedar" as an alternative - we chose that. It is the densest of the cedars available, hence longest potential service. It's beautiful when installed, though it will fade to gray over time. Sean's installation was efficient & prompt; he used virtually all of our pre-existing plumbing, heater & water pump, a major saving. He took time to answer all of our questions, even those that in retrospect were not relevant. Out ageing (outdoor, gas fired) heater failed. Sean diagnosed the problem (that two other service techs did not) and the heater is working well now. Sean will work with you. I can say you will learn to trust him. read more

Sean was great. Very responsive and honest. He fixed my tub in a jiffy. I would definitely recommend him for service calls.

Great work! Figured out the problem very quickly and now it's working great! A+ work.....Hot Tub time tonight!

Sullivan Waterworks took my tub from dead to awesome! He took care of everything in a timely manner and even came back to switch out a filter. thanks a lot. looking forward to the ozonator! read more

Sean of Sullivan Waterworks was professional and effective. Best communication is via email. He was prompt and did not overcharge. I what looked to be a small leak in a 5 year old hot tub. Turned out it was 3 leaks. He fixed them all in an hour. He had a positive attitude and I am very pleased. read more

Sean was great and knew exactly what the problem was and the price was very fair as well! I always prefer to give my business to a small company and it's very difficult to find a great and reliable one in this industry! I highly recommend Sullivan Waterworks! Thanks Sean! read more

Sean Sullivan is the best hot tub repair person in the bay area. Very smart and engaging. Sean installed 4 jets and a new filter. Sometimes over booked and has to often change appointment times. Fair price. I highly recommend Sean. read more

We set two appointment times. The first was rescheduled due to rain, and the second was never met because Sean never showed up, never called with an explanation. Moving on... read more

I didn't' use his service, but I contacted him with a spa problem I was trying to fix on my own. He gave me free advice including the solution I needed. That's the sort of good natured attitude I want in a contractor and when I do need to hire someone, this is the guy I'm calling. read more

Sean came through for us and had our Hot tub motor/pump replaced in time for a party. Later when I realized it was leaking a but he came back, checked it out and gave me very solid advice that led to the leak being fixed - No charge. I have had several dealings with other hot tub repair people that led me to believe they are all crooks and think i am rich and deserve to be ripped off for having a hot tub. Although Sean was not dirt cheap, he was up front and stayed within the estimate. I would recommend him to anyone that does not already have a favorite repair person! read more

Sean is great, he's friendly and reliable and easy to talk to. I really appreciate that he doesn't talk down to his clients. I would recommend him to any newbie hot-tub owners! read more

I found it really hard to find a spa repair guy in the bay area. Sullivan was very responsive over the phone and showed up when they said they would. They charge $100/hour which is a lot but oh well (the next person I called said they were $125/hr). In less than an hour's time they had repaired my hot tub, showed me how to fix it if it broke again, and gave me a few tips to keep it clean without tons of work. I can't ask for more than that! read more

I had a pleasant experience with their service. They were on time, courteous and charged me for 1/3 of what their competition (The Pool Doctors) estimated for the repair. read more

Sean is a great dude. Patient, cool, and I hope none of you use him so he can spend more time on my hot tub

My hot tub wasn't working when I flipped the breaker on, so I called Sean at Sullivan Waterworks and he was finishing up a job only 10 minutes away, so he was literally her in 15 minutes and had the thing fixed in 20 minutes. He showed me the breaker that gets tripped by the moisture detector on the control panel so I could flip it myself next time it happened, and didn't charge me the full maintenance call price since he was already close. Fantastic! Really nice guy. read more

Sean at Sullivan Waterworks knows tubs. I had problems with my newly installed wooden hot tub from the get-go, and after my frustration with the original contractor had reached its peak, I called Sean. The result: problems solved in no time. Sean also took the time to give me a little education on tub maintenance. All in all a great experience and an enormous relief to have someone so trustworthy to call on. If you've got a hot tub or are thinking of installing one, you need to know Sean. read more
