I had a great experience with Justin at Flex Solar. Our existing pool solar system was showing a broken sensor, and he had the problem diagnosed and fixed in about an hour. He was right on time, very kind, and a great communicator throughout the visit. We bought our house with the solar system already installed, so Justin also took the time to walk me through how everything worked and explain the system rather than just fixing the immediate problem and leaving. He even corrected an issue left behind by the contractor who had renovated our pool the week before. Really appreciated how helpful and thorough he was. I would absolutely call Justin again and highly recommend him. read more

Had a pool replaster/tiling contractor recommend Justin. Solar job was well coordinated with the other work going on. Definitely made for an amazing pool season! Professional, Responsive, Fair Pricing. read more

Flex Solar and the owner Justin are top notch! I had them out over 3 years ago ( which I also left a review) to do a repair which turned into a new installation of all new panels today! 10 out of 10! Small business, owner on site and installs himself. Reliable, great competitive pricing! Justin originally looked at my old system set up and quoted me a price. Upon physical inspection , he decided he could lay it out more efficiently and saved me $2,000. Honest! Great business! Highly recommend! read more

Justin from Flex Solar did a great job at our house, fixing leaks and a thermostat. Great communication and service! Highly recommend!!

Our pool guy also recommended them. The service and communication from these guys is the best. They are a small team but the owner Justin is amazingly responsive to any and all questions. Before, during and after they are very easy to get ahold of as we navigate our new system. I can't say enough good things about them and the install and post install process. The product itself has been as advertised. Our pool is kind of tucked in-between trees and the house so it doesn't get much natural sunlight and there is no heating system. Even during a blazing summer the water itself never got all that warm. After install and during summer it added about 10-15 degrees of heat to the pool getting up to 89. It also added a couple months to the backend of summer. It wasn't as hot as summer but still comfortable and usable rather than ice cold. I haven't tested it pre summer but imagine that it will be the same and add a month or two on the early end. If you are looking for a complete year round heating option this may not be it as it is not quite that, but if you are looking to optimize your temperature this system and this company are solid. read more

It was a great experience working with the Flex Solar team! Justin and his crew are fantastic. Such hard workers that handled my job as if they were working on their own home. I am impressed with this company and highly recommend them! read more

Flex Solar recently added pool solar to the roof of my house. The process started when the owner Justin, came to my house and evaluated what we needed. He provided a VERY reasonable quote shortly thereafter, with drawings and specifications. On the day of installation, he arrived with a team and installed 7 panels quickly (in about 5 hours). Justin employs a top-quality install team that are highly skilled and professional. After the installation, he spent over an hour with me to make sure all my pump settings were set for the times and temperatures we wanted. He even cut our oversized pool cover to fit our pool! THAT is the kind of detail and FANTASTIC customer service you get from Flex. TOP. NOTCH. Service. Fast-forward a week after the installation: my pool is now regularly at 87° in APRIL, in the afternoon. Prior to the install, it was in the 70°s, at best (with a pool cover). Furthermore, our connected spa now heats to temperature to in less than 30 minutes, instead of over an hour. Flex Solar did that. When you want pool solar, Flex Solar is the ONLY company for you. read more

I had Justin install a solar heating system for my pool in Jamul. He is extremely professional, offers top of the line products and the installation was done extremely clean. Their workmanship is excellent and he explained everything to me and set up my pool computer to run as efficiently as possible. Our pool is 87 degrees now and we have extended our swim season by 4 months. I would highly recommend using flex solar to anyone looking to get a system installed correctly. Justin even came back almost a year later because my pool guy had messed up the settings and they needed to reset. Justin didn't even charge me for that. That is the true meaning of customer service! Thank you Justin and your team! read more

We had 3 leaks in out Pool Solar system. I contacted 3 different companies, Flex Solar is the only one that bothered to return my calls. They arrived when expected and they fixed all 3 leaks in my system on the first visit. The guys were very nice and did a great job. Highly recommend this company. Darla C read more

Super knowledgeable, prompt with the bid, answering followup questions, and installation. Great install - super clean finish to all they worked on & job site was cleaned up well, everything was finished up nicely. Would highly recommend Justin & his crew at Flex Solar to anyone looking to get pool solar. System is operating just as promised, water is 80+ even with the cloud cover off and on we've been getting. read more

Well over three years later, I have another leak. I discovered Flex Solar is now only doing installation and repairs on systems they installed and they didn't install mine 12 years ago. However, Justin referred me to another company and then he mailed me the piece I needed and provided guidance on repair in an email. I did it myself no problem, again extremely happy with Flex Solar, will use them when I need a new system in a few years. read more

We have used Flex Solar twice: once a few years ago for a minor repair, and more recently for an uninstall/reinstall and partial upgrade. They have been a pleasure to work with, and very responsive. Justin was EXTREMELY patient with my questions on this last job and worked around the schedules of two other contractors without any difficulty. Everyone we have interacted with at Flex Solar has been courteous and has seemed interested in doing a good job. Their communication, organization, and follow-up have been top-notch. read more

Flex Solar installed solar at my house back in October. While the installed went well and i love the solar pool heating. They are responsive and forthright, explaining the systems and panels. I was impressed with the care Justin took with regard to my older tile roof. He pushed the install to later because the heat make the tiles more breakable. Also they only had one person go on to the roof to minimize issues. An issue recently came to light, they were quick to response and solve the issue. Would recommend. read more

I got a referral from my pool service person. I got the estimate, Justin explained everything needed for installation. He helped us understand what kinds of modifications would be made to the existing equipment and the roof. We booked him and in a couple of days of install work, we had our working solar pool heating system. He explained how it all worked, and he noted that our roof was in good condition. He goes on a lot of roofs and knows generally when he's on a roof that needs replacement. We just happened to have people from roofing companies showing up at our door, telling us how we needed to replace the roof quickly. Justin was professional and everything was straightforward. I definitely recommend this as an alternative to gas or electric heating. It's probably less of an install cost and nearly no extra monthly cost, and San Diego has a lot of sun. It's a no-brainer with this company! read more

Out of all the pool solar companies I've worked with, Justin with flex solar is by far my favorite. I have a pool service company so I have worked with a number of solar contractors previously. It has often been difficult to get them to come out for an estimate or warranty call. This is not the case with Flex Solar. On all the jobs that I've recommended him, he shows up for the estimate on the same week if not the next day. He is honest and upfront about pricing giving all the different options. He will make sure that you get the correct system 4 your size pool and application. He is always available via text or phone call for tech support. Highly recommend.

I am glad to have found Justin with Flex Solar to re-route my pool solar pipes. He shown on time for both estimate and the repair. He did a great job re-routing the pipes and his price is very reasonable. Justin is a great guy, intelligent, great to work with and very knowledgeable regarding pool solar heating systems. He is always available via text or phone call as well. Justin has just earned a new customer. He is now our go to guy for all our pool solar need in the future. I would HIGHLY recommended Justin for all your pool solar regardless big or small job. read more

Justin & Carolyn responded in a very timely manner & were able to schedule an appointment to repair our solar water heating system for our pool the very next day after we communicated. It turns out Justin was one of the people who originally installed our system with the company he previously worked with! What a small world, indeed. Justin & his crew arrived on time & were able to complete the repairs within 30 minutes. Many thanks! read more

Flex Solar was responsive, professional and most importantly, delivered with integrity. We had another cheaper quote but we are so glad we chose a team that would consider the quality of the installation and back it up. Little things like roof attachments matter and when I broke a pipe gardening on Easter, they were responsive to come bail me out. read more

I can't recommend Justin highly enough. He worked with me over the course of a couple months, coordinating with roofers and others, and was always professional, communicative and on time. He's a wealth of knowledge, does fantastic work, and is a pleasure to work with. Do yourself a favor, and don't use anyone else! read more

Superb service. Contacted them on Monday requesting urgent service. Very friendly and responsive. They accommodated. Job was done the next day. Very pleased. read more

I've used Justin for a number of pool solar relocations, installs, and removals. My customers love him, and I have nothing but great things to say about his work. If you're looking for solar pool heating, you've come to the right place! read more

We were super happy with the service from flex solar. The install made a huge difference to our pool water temperature. We are initially on the fence about whether to get solar but the results were immediately noticeable. The team was very professional and knowledgeable and I would highly recommend the company without hesitation. read more

Justin and his crew are second to none, amazing service, my pool solar was installed perfectly. If you are looking for the best company to come out and do your pool solar, look no further than Flex Solar. Thank you Justin, Chad, and Ryan!!! read more

Thank you Justin for coming out and fixing my solar issue. You remain the best in the business. If you need pool solar, Flex Solar delivers!!!!! Still working great after 4 years. Mark read more

A few years ago, we had some issues with our roof top pool solar heating, so our pool guy recommended that we contact Justin Sharp at Flex Solar. This turned out to be an incredibly valuable piece of advice. Justin was able to provide us with a temporary fix to the issue, which allowed us to get a couple of more years out of our system. Justin was also the first call we made to replace our actuator when it went down a year later. So when our roof top system finally gave out after a great 23 year run, it was a no brainer to reach out to Justin and his team and their prompt, reliable, responsive, and highly trusted service. As was the case with each of our two previous repair needs, Justin provided a few options, explaining thoroughly what each would deliver. His honest, straightforward communication and explanations provided us with the insight that we needed to make an informed decision. He also indicated to us that after 23 years, the integrity of the felt under our tiled roof might be compromised. We took his recommendation, and sure enough, we needed to hire a roofer to make the repairs prior to the installation of our new system from Flex Solar. While hiring a roofer wasn't a budgeted expense, Justin actually saved us money with his factual insight, allowing us to be proactive and complete the necessary roof repairs. With a team that is committed to service, communication, integrity, and quality work, you need not look any further than Justin Sharp and his team at Flex Solar. read more

When I first started researching solar thermal heating for our pool last year I got several quotes and had a few companies come onsite to provide bids. Justin and Flex Solar had the best pricing by far and was the most responsive of all the companies I talked too. In fact, as part of my research I contacted quite a few pool service companies as well, and I had 3 of them all tell me that if I wanted solar thermal I should contact Justin and Flex Solar. This tells me he has an outstanding reputation in the industry already as he's held in such high regard by other pool companies in the area. In any event, the install took 2 days as he did the work by himself (would have been one day but his usual partner was not available to help out). But the work he did was very clean and best thing was that there is no leaks which was my biggest fear as we have a spray polyurethane foam (SOF) roof which is not very common and it seems like not many installers know how to work with it. In fact, another company I had talked to took forever to even get me their quote because he was taking so much time trying to find a roofing company that specializes in SPF roofs to work with them on the install. In the end, Justin did all the right research and used all the right precautions to make sure that the install would require the least amount of penetrations needed and sealed them up up tight and proper. Justin also guarantees and warranties all his work so I'm confident the install will not cause any issues and if there are any, he will make sure to take care of it. Justin also went out of his way to come back and paint the PVC piping that went up the side of our exterior side wall to match our recently painted home and also gave lots of great advice and made sure our variable speed pump was programmed to optimal levels and to take into account the required flow to maximize heat but keep energy usage low. On a personal level, Justin is just a great guy, who's super down to earth and easy going. I'm sure most people would have no problem working with Justin at a personal or professional level. Pool water temperature has constantly broken 80 degrees all last week and we're ecstatic to be able to swim so early in the season thanks to Justin and Flex Solar! If you need solar heating for your pool, look no further. You won't be disappointed if you give Flex Solar a call. read more

Justin from Flex Solar came and worked on my pool solar leaks and other sensor issues. Very professional and honest. Cost was very reasonable, on time, great communications and respected my property. All that you would expect from all the other 5 star reviews here. Will definitely use them again and recommend them to others. Thank you Justin. read more

Found Flex Solar and Justin through our pool guy. We had a leak and I called Justin to check it out. He came right out and checked out the problem, then fixed the leak. He also did some other minor tweaks, fixes and adjustments to make sure we were running at top capacity. All for a very reasonable price! Justin is a great guy, intelligent, great to work with and very knowledgeable regarding pool solar heating systems. We are so very glad we found him! HIGHLY recommended, and he is NOW our solar pool "go-to" guy! read more

Just had my solar serviced. The guys were great. Arrived on time and explained things clearly. Great service and best price I was given. I will be using them again. read more

The best pool solar company. My pool solar had an ember land on my roof from the west fire. Justin was there the same day to fix it. Thank you. read more

Justin Sharp was on time, had the part with him, provided quote and installed during same appointment. Great service! Thank you!!!

I reached out to Justin as a referral from my pool service company. We need our roof replaced and have existing pool solar that I was unsure if it could be removed and reinstalled safely. Justin spent over 15 minutes on the phone with me to explain some of my options and then came to my home to assess the current pool solar. He was polite and timely. He was able to provide even more thorough recommendations even without the guarantee that I would be able to move forward with the project. I am very thankful for his advice and recommendations. read more

We absolutely cannot say enough about Justin Sharp. He was timely, reasonable, friendly, and informative. I would highly recommend him! We love our new warmer pool! read more
