John is great and I highly recommend. Until earlier this week, I had no idea pool walls cracked. I called around and received so many different repair options. It wasn’t until I spoke to John that I had a sense of confidence in someone knowing that they knew what they were talking about. He explained all options on next steps and was the most informative. Truly felt he had our best interest in mind.

John did a fantastic job, above and beyond what I asked for. He was on time, explained what he was going to do and how long it would take. The repair went very smooth. He even scraped off several calcium deposits and the pool looks so much better.

John is a very busy man so it took a few attempts to get a hold of him. After that it was a breeze. He replaced the step in a couple hours without draining the pool. That was half what another company quoted and they needed the pool drained and a week downtime! We were lucky that he needed to come to the west side to pick up supplies the very next day and was able to work us in. Usually he is booked for a couple weeks. I recommend him without hesitation.

I sent him pictures and he came to my house and removed all the calcium nodules the before and after we’re amazing. He was amazing and I would highly recommend him to anyone. He was very knowledgeable. Thank you so much for being honest and so professional!
Description of Work: I had spits in my pool and had several pool companies come out and told me I need to have my pool replastered. I find UnderwaterOps on line and sent it some pictures. He told me they were calcium nodules and he could fix them by going under water and saving me thousands.

John did an excellent job of repairing the rebar rust stains at the bottom of my pool. Because he performs the work underwater using his scuba tanks and air driven power tools, he saved me a lot of money associated with draining the pool (new chemicals, refilling with water, etc). Also saved me a lot of time as I didn’t have to wait before using the pool again

I highly recommend anyone who needs a pool repair contact Underwater Operations. My pool took about 2.5 hours to fix, and looks great. He was even able to custom match the pebble tec which wasn't available anymore due to the age of the pool
Description of Work: I had two cracks in my pebble tec pool which is around 18 years old. One of the cracks was losing water at a rapid rate of appx 3" per day. Was referred by a friend to John at Underwater Operations. Not only was John prompt in returning my calls, but was frequently in touch to let us know when he would be able to come out and fix the pool. He was also very knowledgeable, courteous and quick to respond to all my questions. And the price was well below what I thought it would be and well-below other quotes for similar work.

This could not have gone better. John is very knowledgeable and explained every aspect of what he was going to do for us. He took great care of our property and left it cleaner than he found it. He was always punctual and a delight to work with. Our pool is beautiful again and you cannot see where he patched in three places. Your pool is a big investment and you want things done right! I have no hesitation at all giving my highest recommendation to John and his company.

It went great. He was very personable and professional.
Description of Work: He repaired rust spots on the bottom of my pool. He removed small sections of plaster and rusted rebar and repaired them so that I can hardly tell where the repairs were. I didn't have to drain my pool so that was an added bonus.

After 4 other pool "repair" guys told me the only way to fix the rebar bleed in my pool was to totally re-plaster at a cost of 6k +, I was pleasantly surprised when Joe quoted his price over the phone (subject to visual inspection). He came out, saw the pool and priced the job the same as the phone quote. The patches matched the surface material to the point that you had to know where to look to find it. He also sanded off numerous calcium nodules that had built up over the years.
Description of Work: Cut out and patched two spots where rebar was bleeding rust. He also sanded off calcium nodules throughout the pool.

John was amazing. I submitted a request online, he called me immediately and scheduled to fix it the next day since he had a cancellation. Showed up on time, did a great job, cleaned up after. Charged less than other quotes and I didn't have to drain my pool which saved me even more money. I highly recommend him.

Description of Work: We had two cracks in our plaster pool. One was not leaking the other was losing 20K gallons of water a month. We were told by a previous company that we would have to drain our pool and have in empty for 3 days to patch the cracks we were quoted somewhere around $1500 to have that done. My husband did some research since we were nervous about draining our pool in the Phoenix summer heat and came across John - Underwater Operations. He talked with me over the phone to get an idea of our problem. He gave me a detailed description of what he could do and how much it would cost along with the other options that were out there if I chose to do something else. He came out within a couple days of our conversation, which was fantastic since our water bill had been insane. When John came to our house, my husband and I had a lot of questions and he took time to answer them and to explain what he would be doing and about how long it would take. We were so impressed and thankful for his patience and thoroughness. He fixed the leak within the hour and it has been holding ever since. We highly recommend John - Underwater Operations. He is very helpful, informative, and is a person of integrity.

The entire transaction was great-- very good. John gave me quotes over phone and actuaslly cam in lower when he got to our home and reviewed the situation. Attempted to discourage me from attempting to repair spots in shallow end, Said his experience was that they didn't last. I really appreciated the honesty. He was puntual. Kept me informed on time line. DID A GREAT JOB.------------------------Dean--- phoenix
Description of Work: top stair into pool had numerous spots where plaster popped off-----same situation in shallow end--- due to the repair of a rebar the prior year when it was to hot to drain pool-----John removed approximately a 1/2 inch area on the top of the stair and completely recovered it -- looks great--- he came back the following day in scuba gear and filled many of the small areas in the shallow end----stated he was doubtful they would stay (very upfront prior to doing work) still in place and looks great also

They are fantastic. We have a plaster pool in Arizona. Sometimes, they get like a mark either metal re-bar coming through or actually, it's a de-lamination where the white plaster pulls away from the concrete and it leaves a big gray circle. I wasn't ready to drain my pool and re-plaster it at this point of time because it was $5000. They can actually fix the plaster and repair it underwater. They don't drain the pool. We called and they did a great job. It is a unique service and it is hard to find someone to do that kind of job. His name is John Malder. They were timely and came & gave a quote. They performed according to the quote and they were professional. They were out in a day.
