After searching high and low for someone who services above-ground hot tubs, I finally found High Flow Hot Tub and decided to give them a chance. Tony responded right away and was able to schedule a diagnostic appointment quickly. I was worried the repair was going to be expensive, but Tony worked his magic and got it heating again without needing any new or costly parts. The diagnostic and repair fee was very reasonable. I then scheduled a full deep clean to get it ready to use. Once again he showed up on time and finished the job spectacularly and quickly. I 100% recommend High Flow Hot Tub for all your hot tub needs. Their weekly maintenance package is also a fantastic deal.

The quality of work was excellent. What really stood out was how much time he took to explain everything to me. He didn't mind me watching and walked me through what he was doing step by step, helping me understand how the hot tub works. That made me feel 100% comfortable and confident in the repair. I'll definitely be using High Flow Hot Tub again in the future and would highly recommend them to anyone having issues

    We just finished a complete renovation of our pool with Oscar's Pool Service, and I can honestly…read moresay it was one of the best decisions we've made as homeowners. When we bought our house three years ago, we knew the pool needed to be redone. Unfortunately, because of other major repairs, we had to wait. Our house was a flip, and whoever patched up the pool before us did a quick, cosmetic job that started falling apart within months. The plaster came off in sheets, the 1960s tile was covered in decades of calcium buildup, the coping was old red brick with mortar literally crumbling out, and some jets and plumbing didn't even work. The pool was technically swimmable, but it was depressing to look at. This summer our weekly pool cleaner told us the plaster was about to fail completely, so we started calling around for estimates. Most of the big corporate companies gave us inflated quotes and made us feel like just another job number. A trusted friend recommended Oscar's, so we checked Yelp, saw all the great reviews, and gave him a call. Oscar came out immediately, took careful measurements, walked us through every detail, and his knowledge and professionalism instantly won our trust. From there, the process moved quickly. Within a week of signing, his crew demoed the entire pool in just a few hours. We got to choose tile from several suppliers and ended up with a beautiful pebble mosaic that matched our house. At first, we thought we'd keep the old red brick coping, but at the last minute we switched to a modern dark gray brick. Best decision ever! It completely transformed the look of our backyard. As often happens with older homes, surprises came up: our original 1964 gas and electrical lines were corroded and had to be replaced. Oscar handled everything--brought in trusted contractors, coordinated the work, and saved us the headache of dealing with multiple companies. While we were at it, we upgraded our equipment to a top-of-the-line Jandy system with Wi-Fi controls, plus added a heater and automatic pool filler. Yes, the budget went up, but every upgrade was worth it. Watching the transformation was amazing. Once the new tile, coping, and plaster went in, it felt like we had a brand-new pool built from scratch. The white plaster makes the water sparkle, the equipment runs quietly and efficiently, and with the heater and lights, we can swim comfortably day or night, year-round. Beyond the work itself, what made the experience so special was Oscar and his family. He's personable, honest, hardworking, and clearly cares about his craft. His crew was professional, respectful, and fast. By the end, it felt like we weren't just hiring a contractor--we were working with people who truly cared about making our home better. Now every time we step into our backyard, we can't believe the difference. What was once an eyesore is now the centerpiece of our home, and we're enjoying it constantly. If you need pool renovation, plaster, tile, coping, or even just reliable weekly service in the San Fernando Valley--call Oscar's. He's the best! https://www.youtube.com/watch?v=3DKKSP_c4UY

They weren't the cheapest quote I received, but they were right in the middle and were the only licensed pool repair service among the companies I considered. They were responsive to my questions throughout the process, and the installer was efficient, professional, and had the new pump installed quickly. Overall, I'm very happy with the work and the experience. Would I hire them again? I hope I don't need to anytime soon...but if I do, I would definitely call them again.

As with any large project, there were a few issues that came up along the way. What impressed us most was how quickly and professionally they addressed our concerns. They took the time to make things right and ensured everything was completed to our standards, which we really appreciated. The finished pool looks fantastic, and we're very happy with the end result. Because of our positive experience, we've already referred them to friends and neighbors who are considering pool remodeling of their own. We wouldn't hesitate to recommend them to others looking for quality work and excellent customer service. It's hard to find a company that stands behind its work and truly cares about customer satisfaction, and this team did exactly that.

One of my favorite things about their service is the email update we receive after each visit. It includes a photo of our sparkling clean pool, the current pH levels, and even confirmation that our gates were closed and locked. That kind of attention to detail and communication gives us tremendous peace of mind. They were an absolute godsend after dealing with consistently poor service from our previous pool vendors. Even better, The Lazy Pool is actually cheaper while providing dramatically better service! They've also done excellent work servicing our pool system and filter whenever needed. I really can't recommend The Lazy Pool highly enough. Great service, great communication, fair pricing, and people you can trust. Five stars all the way!

This company is the best, I'm extremely happy with my pool service company. Their service is excellent, they're always respectful, and they show up on time every single week. Their pricing is the best I've found--especially impressive because I have a saltwater pool, which is usually more expensive to maintain. They keep everything running smoothly and looking great. Not to mention very informative I received photos of my pool when it's serviced and notifications when they will be cleaning the filters and the salt cell. Highly recommend!

Most were good , some not in regard to price and effectiveness of repairs. About 10 years ago I saw David's truck out front of a neighbor's home. I gave him a call to set up an appointment. He came over and told me exactly what the problem was, the price and when he was available. His price was competitive and lower than others I had used in the past. Over the years he has provided professional, quality and technical service. Once I had a variety of problems he walked me through which I should fix first then perhaps wait on the others. In the end he fixed it completely. He's a patient listener, kind and extremely knowledgeable due to his long years of experience. He schooled me as to which chemicals to buy to maintain my spa. I most recently saw that my spa was leaking. I called him and he came right over the next day. Of course the spa was suddenly completely dry and showed no leaks. He had me fill the tub to its proper level of water. Suddenly it started leaking. He located the problem and fixed it I very highly recommend David for any of your spa needs.
