Great working with Cooper at Pinnacle Pool. I love supporting this kind of establishment, a small business owner providing quality service at a fair price. Cooper was professional, continuously updated me on timing (due to a big traffic incident) and was able to replace my broken heater in a little over an hour. Would definitely call him again for pool repair or leak detection. read more

Had a leak in my pool and needed leak detection and repair. Several of the companies I contacted via Yelp said they don't do leak detection. Fortunately for me I found Pinnacle Pools and Cooper came out and found the leak and then scheduled a repair. Cooper was easy to communicate with and was honest about what was needed and did not do any up selling like several other companies I called. The repair was done quickly and the price was less than those quoted by other companies. I've saved a lot of water and able to enjoy my pool again thanks to Cooper. read more

Cooper was so helpful for fixing our pool leak. From beginning to end - identifying source of leak, fixing it, patching up concrete - he was an efficient expert who clearly knew what he was doing, and kindly walked me through every step. He saved us so much time and angst of spinning our own wheels trying to figure out the problem. Can't recommend enough! read more

Great experience with Cooper for my pool heater replacement. He quoted me a really good price and stood behind it. Even when there ended up being additional work needed he never altered the original quote. He did an excellent job and it was really nice to work with someone with such integrity and professionalism. I will definitely be using him in the future! read more

Cooper and his team did a beautiful pool remodel for me. I was losing water every day and I knew it was time to address my pool issues. Cooper is very knowledgeable, professional, and honest. He identified the problem as the skimmer, which he promptly replaced and the leak stopped. I then asked him what a remodel would cost. He was very interested in giving me several options that would fit in my budget, and at the same time, give me the aesthetic result I was looking for. I told him that I liked the classic tile that I had. He looked at it, thought it was in good shape, and offered to polish it for me rather than replace it. The polished classic tile looks beautiful with my new, replastered pool! Cooper was so pleasant to work with. I cannot be more pleased with every aspect of this job! I am already recommending him to my friends. read more

Can't say enough good things... I broke a filter unit on Sunday, reached out via yelp and they responded Sunday night. He was here Monday afternoon and in a couple hours had a new filter unit piped in and working. That's awesome. read more

Cooper is the man. Hooked me up with a new pump at a very fair price and did an A+ job hooking it all up. I don't know a lot about pool equipment and cooper took his time explaining to me the pros and cons of my options and in the end got me up and running at a price I'm happy with. Give him a call - you won't regret it. read more

My pool just developed a suction leak and was getting air bubbles into the returns. The pump was also sucking air, collecting air into the view chamber. I emailed Cooper and he suggested I replace the o-rings in the three way suction valve. Bingo ! a correct diagnosis and easy fix. Thank You Cooper. Definitely my Pool Guru. Highly, highly recommended!!! read more

Cooper is now my guy. Seriously! Better price than anyone else, but more importantly, he was really nice, professional and knew what he was doing. If you have a job, just call him. You will not be sorry. read more

I called a few pool companies in the greater Walnut Creek / Concord / Pleasant Hill area. Many went to voicemail, some said they weren't accepting new customers (without even screening the nature of the call), yet Cooper not only took my call, he came out that day in order to take a look at a loud noise coming from my equipment. Cooper was kind enough to push to make it to my house despite a busy schedule and while temps were over 100 degrees. Not only did he take a look he saved me money by finding an aftermarket pump that matched the rest of my equipment. He was honest, fixed the problem quickly later that week, and saved me money. His cleaning service is actually more affordable than mine too, and with twice the visits. I am going to call him for all repair matters and weekly cleaning moving forward. Thanks Cooper! read more

We have used Pinnacle Pool to service our pool for the past couple of years. Everything was good until recently when Cooper started using other people servicing our pool. Although we still pay $95 dollars a month for service every week it looks like we don't even come close to that. Since June 23rd his company has only been out 7 times when it should have been 20 times. Not to mention that the guy he sends out spends 25 minutes sitting in his car doing who knows what before spending 3 minutes "taking care" of our pool. Today broke the camels back. Instead of putting the pump on top of the pool cover to pump the water off he just left. This is the service you use to take care of your pool! The pump is literally sitting next to the pool equipment! read more

Called Cooper and explained my booster pump was not working. He first checked breakers and circuits to make sure the pump was the problem. He ended up replacing the pump and checking the sweep function. Great speedy service on a rainy day read more

Pinnacle Pool Leak Detection has done an outstanding job of pinpointing a leak that was causing my pool to lose more than 1" of water per day. They were very careful and systematic in their approach to discovering the problem and were able to completely repair the leak. Also, they were very friendly to work with and had skills in every aspect of pool repair and renovation. I would highly recommend this company to other pool owners Thank you Pinnacle Pool !! read more

My experience with Pinnacle Pool exceeds five stars. I had Pinnacle Pool come out to find a leak in my swimming pool after doing a ton of research on other swimming pool Leak detection companies that serviced our area. I was immediately impressed with how personable and professional they were and was very pleased to find that their pricing was reasonable. They were able to find the leak and fix it. They found two leaks in my swimming pool plumbing at the return line and skimmer. They were able to make all of the pool leak repairs in a timely manner. They were able to come out in one week and were courteous and again reasonably priced. I ended up having them remodel my entire equipment system, my pool filter pump to variable speed and installed automation. Beyond satisfied and recommending to all of my friends. Keep up the great work guys!!!! read more

Every time I've had a concern with my pool I have called pinnacle pool. Their response time is very efficient. They are knowledgeable and listen comprehensively. I would trust them with the life of my pool over any other pool company I have ever used. Keep up the great work! read more

I'll try to brief because there's so much to say great things about Cooper. His company went over board with great honesty and service. I was amazed that out of 6 companies he was more honest about prices and equipments needed for my house in the Oakland Hills. There were other companies with quotes higher than his by at least $3,000 dollars. If there was a 6th star I would rate that for pinnacle pool, because at the same time Cooper was done my family and I went for a vacation to Yosemite for 6 days and he did not bother to ask for the payment. When I came back I did contact him and told him I'll leave a check in the mail box, got real busy never got to do it and he was very patient about it. Anyway he finally got his check and later that week I want to turn on the hot tub, it didn't work. So I text him around 9pm, thinking he will call me in the morning. But he replied minutes later and came to check it the following day and discovered just a loose wire. read more

After having used several leak detection and repair companies, with questionable results, I was referred to Pinnacle. Cooper not only found my leak quickly, but also squeezed me in to his busy schedule to complete the repairs. After he was finished, I was amazed at his clean up. It was as if he was never there!!! Also, his price was completely acceptable for the work he did. I would highly recommend Pinnacle Pools to anyone looking for pool service or repairs. read more

I noticed that we had been losing water in our pool rapidly and was concerned with all the rain that it would saturate our yard. Pinnacle Pool was able to come out quickly, diagnose the problem, identify exactly where the leak was at and fix it extremely fast, all for a very reasonable price. I am quite happy with the service I received from them! read more

I was referred to Cooper by my pool guy. My drain cover on the deep end would not stay on and almost swallowed my pool sweeper tail. I love Cooper. He was so easy going and followed through coming over as soon as he could. He had to dress to dive and drilled a new cover into the deep end. I had another problem brewing at the same time which was a leaking/gushing booster pump! I asked Cooper if he could get me a specific brand and install it right away. He squeezed me in and got my pump installed pronto! Cooper is very competent, pleasant and prompt. I highly recommend him! read more

Pinnacle Pool - Deep End drain cover! - Pool & Hot Tub Service Near Me - Walnut Creek, California

We are in the middle of a yard renovation and the pool company we had hired was not responding to repairs needed quickly as we had contracted them for. So, I called Cooper. He called back within two hours and though he was very busy offered to come help with temporary repairs till he had time to come back to keep our yard renovation going. Appreciated his help, gave me some hope! The pool company did respond finally and we did not need his help but will definitely keep him on file for future needs. Thanks Cooper!! read more

Hands down the best pool service EVER! Love Love Love Cooper! He was responsive, friendly, knowledgeable and affordable. The cost for upgrading my pool heater and pool pump was WAY better than the other pool service I was referred to by my friend, by far. I am so glad I went with Pinnacle Pool and am going to recommend their weekly swimming pool service to clean my parents pool who live in Orinda and are looking to replace their current pool service. read more

I've used Cooper at Pinnacle a few times now. Always has been very reliable, professional, friendly, and honest. I'd recommend him to any friends or family. Whether it's a pool pump, pool renovation, or complex and rare in-floor pool cleaning system (unfortunately like mine), Cooper is your guy. Glad to have someone I can trust in the Bay Area for all my pool needs. read more

I have called on Pinacle Pool to help me with my pool many times, for everything from killing algae, to leak detection, and they have always been very professional, and provided me with the best service. I recently referred them to my in-laws because their pool was leaking. Cooper found the leak, replaced the pipes, and then installed a variable speed pool pump. The pool does not leak, and they are saving around $100 a month with the recent upgrade to the pool pump. 6 Stars!! read more

If you have an old pool pump that won't start, call Cooper before replacing it! We had a couple different companies come out to fix the pump and quoted me thousands of dollars to replace it. They said it couldn't be fixed. Cooper came out and showed me how to manually start it. Not only did he get it working, but he showed me how to do it myself if it ever happens again! I know my pump is old and it won't last forever, but it was nice to not have to spend thousands of dollars right now when it wasn't necessary. read more

Cooper was awesome. Came and did leak detection and has repaired a pump that wasn't functioning great... I will use him again

Pinnacle Pool has always provided great service. Cooper goes out of his way to explain options, make recommendations, but does not push unnecessary services or products. He is punctual, returns calls in a timely manner, and I greatly appreciate his honesty, integrity, and work quality. Highly recommended! read more

I am very impressed with Pinnacle. I'm a real estate agent and was in a pinch needing a quick inspection on a pool. I called Cooper who was extremely responsive. He said that he'd be in the area within the next day or two and would stop by, which he did. His quick response time and explanation of the issue provided me with knowledge to share with my client and help in finalizing our purchase offer. I highly recommend. read more

My pool was turned off months ago by my then pool service as I was told the main pump no longer worked, a few months later I was given another estimate of over $3,500 as I "needed" the new main pump, the sweeper motor and timer, and a whole new filter system. At the time I didn't have the funds and was going in for surgery and simply couldn't deal with it. This month I finally went about getting quotes. I contacted 4 companies, Cooper at Pinnacle looked more carefully than most and actually turned on the equipment and noticed the pump seemed to work. The pool was not full enough to run so he advised I fill it up enough to run the pump and run it and he would return in two days to do the leak detection at a reasonable price. I did as he suggested and the pump worked fine for two days running over 6 hours each day. He did the leak detection discovered a skimmer leak, did a temporary repair of that (will have it taken care of when the pool is resurfaced in a few months. He also agreed to return at no charge to do a final pressure test on the drain so that we know for absolute sure it is not leaking. He checked the pool sweep motor and the filter system and discovered that they are in perfectly good condition. Since I was convinced by the last service and other estimates that they needed replacing he could easily have installed new equipment. He fixed the skimmer and will return to repair a broken line in the above ground equipment, and did the leak detection for under $500. Sadly other pool places are obviously not honest. One actually told me that they could bid by the hour vs. by the job, but they would pad their hours so they made the extra money they wanted to make. As a disabled, over 60 year old female, he could easily have taken advantage of me. The fact that he didn't, and actually checked the equipment rather than just assume it all needed replacing, proves to me that this is a company I want to do business with, as well as let others know what a gem Cooper is. I highly recommend Pinnacle Pool. read more

I called Pinnacle when my pool pump started screeching. I talked with Cooper and we made an appointment for a couple days later. On the phone he told me the cost to replace and said he would come by to verify I needed to replace the pump. He came by at the time specified and let me know he could replace the pump. Cooper replaced the pump but the suction was not performing as expected. We made another appointment and he again was right on time. He had a great attitude and was determined to resolve the issue. He researched the pumps and installed a new pump. He also repainted the PVC pipes and followed up with a call to verify the pump was working properly and to my satisfaction. If I have any other problems, Cooper will be the first person I call. It was a real pleasure and refreshing to work with a contractor who was on time and did what was agreed upon and even went beyond in level of service and commitment. read more

As everyone here agrees, this is the best service you are going to find. I have been using their service for about a year and am very happy with their business. They treat their customers like family and do not take advantage of us. They are very smart people, know pools (obviously) and know how to run a successful business. They are family owned and operated. I love this service! A nice relief to have a service that is handling my pool as if it was their own. I highly recommend them! read more

My 1 Star review in 2017 was then, this is now. As many have indicated " Cooper is THE man " and I would agree. My pool, like most tends to leak on occasions, and no problem as I know Cooper is a call away. And not only does he find the leak, but he repairs them as well. I wonder what else he does; he is here now, so I'll ask him. read more

I went through two other pool professionals before finding Cooper. And these reviews were right. Cooper is smart, experienced and honest. These are things you want in a professional. Cooper could have very well tripled his estimate. He knows we know nothing about pools and pool leaks. But he didn't. He charged a fair amount and did the job properly and on time. He shows up when he says he will and makes himself available to my ignorant questions. :) Thank you Cooper! You provide such a wonderful service to the community! :) We all appreciate you!!! read more

Pinnacle Pool service is outstanding. The service personnel and the owner provide exceptional service and work quickly to solve any problem. They make it a priority to save the customer money and reduce expenses whenever possible. I recommend Pinnacle Pool service without reservation. Sincerely, Ron B. read more

I purchased a house with a pool and will be the first to admit that prior to owning this pool knew nothing about pool care or maintenance. Due to the age of our pool and wear and tear we have noticed in the grout, I contacted Pinnacle Pool to in hopes of them providing guidance around whether or not I needed to replace the mastic I had done as part of a DIY project last summer and advice around replacing/repairing the grout. Cooper called me the same day I left a message and came to my home to look at my pool less than 24 hours later. Cooper spent a lot of time looking over the areas where we had concerns and gave us great advice about how to protect and treat our pool going forward. Both my husband and I were truly impressed with Cooper's knowledge and willingness to assist. read more

Cooper and his team at Pinnacle Pool are the best. We have been disappointed by pool and leak detection companies in the past that had 5 star ratings on Yelp and we discovered they didn't deserve that rating. A well known leak detection company from Sacramento couldn't find the leak (a broken water line!) and charged us full price. We discovered Pinnacle Pool services the El Dorado Hills - Folsom area and gave them a try. Great decision! They came out and found the leak and pinpointed leaks from the return line and skimmer and repaired them both at a reasonable price. They also came out and diagnosed a failure in the air flow switch on the master temperature heater and repaired it on the spot. We later had them install a new swimming pool heater. This company is terrific and we will continue to use them for all of our swimming pool needs. read more

Be aware of the poor service once you subscribe. They tricked us into buying some remote control system that never worked on the app and my hot tub kept draining every time I turned it on. When asked, they didn't bother helping us fix it and just said it's a feature not a bug... we have wasted tons of water, and it does not seem to concern them... read more

I would highly recommend Pinnacle pool make sure you ask for Cooper O'Neill after using American Leak Detection previously and was very disappointed with the service. Cooper O'Neal and his company are definitely the way to go very professional very fair price and will gladly recommend up to my family and friends. He even came out to my house and San Lorenzo which is not his territory read more

I have called Pinnacle Pool twice and no response. I had clearly left a message for them to call back. The first message I had left Saturday and now it is Wednesday evening. Even if you are busy call back! Does not take much! I have never changed my opinion about a review, however, since my last review Pinnacle Pool has contacted me to understand how they can help. I had a good first discussion with one of the owners and only a few days later Cooper came by and looked at our Pool leak. He found the problem fairly quickly and I believe most of the damage has been repaired. I lost more than one inch of water per day and Cooper took a lot of time to check various possible causes. I got to know Cooper as very trustworthy and knowledgeable. I am very happy with the progress so far. read more

Pinnacle Pools has been the best pool company that we have used. They are knowledgeable,honest, and they always bring 5 star service. I have refered them to people and everyone has felt the same. Thank you Pinnacle Pools. read more

I called pinnacle pool about possibly having a leak in my pool and they came out that week and found the leak in our pool! Cooper was very friendly and knowledgeable. We loved the service so much, they now clean our pool weekly. Affordable, prompt, friendly pool service. I have referred them a number of times to friends. Five stars!! read more
