    Model

    Mark is not only awesome and easy to work with, but totally honest! Pump went out, got a bid on yelp from 10 different pool companies. Little did most know I did my Youtube research and determined the driver was bad on my pump. Several guys said I need a new pump and that they don't make parts for my model anymore. Mark said I have an extra driver I can use to fix your pump and came out same day. Awesome to deal with call him if you need help! My quotes went from 3k to a couple hundred cause of his integrity and honesty!

    Neat work

    Marcus installed my pool pump. He did a great job and I was thoroughly impressed by his craftsmanship. He took the time to explain the work that he was doing, did not cut corners and even fixed some actuators that were unrelated to the pump. I would 100% recommend him to friends and family.

    Our pool heater is a little old. Thankfully, Marcus was still able to repair the E05 error we were getting.

    Ask the Community - The Pool Nerd

    Do you recommend DE filter or cartridge?

    Cartridge is what I recommend.

    Do you work on pentair ultra temp heat pumps?

    I can install them but I can’t work on them

    Do you paint swimming pool?

    No i don’t. The chemicals will eat away at the paint over time. Never looks good

    I would like to replace my pool pump with an energy efficient vsp pump. I have a smaller pool. Do you sell and install?

    Yes I do

    Do you service Laguna Niguel?

    I only do repairs in that area.

    Greetings, I would like to know if you service the Carson area? I believe I have a leave in the pump…

    I was having an issue with my pool heater, and he was able to identify the issue and fix it on the same day.

    Words can't express how grateful I am for Beachfront Pool service…read more We recently had a new roof put on our house and the roofers did not cover the pool like they promised so there was wood dust, nails and plastic covering the pool floor. Paul was amazing he responded immediately and got to work as soon as he was available. He brought the pool back to life. And right before a holiday weekend. AMAZING!!! I recommend Beachfront Pool to anyone in need of pool service.

    We hired Beachfront pools to care for our newly built fiberglass pool in 2022. We used them up…read moreuntil this past June (2026). Paul almost never cleaned or serviced our pool. Two different guys from his company did the cleaning and any maintenance. This past May we went to use the pool and it was filthy. We actually never saw the guy cleaning the pool it just seems like he checked the water. He would throw in our Hayward Shark vacuum and leave. We paid $165 for the basic monthly service then it went up to $175. Almost every other month the bill basically doubled for maintenance like filter cleaning, etc. We were not told of charges beforehand, they would just appear on our monthly bill. We trusted and paid because we wanted to be diligent with the care and upkeep of our pool. The communication was very minimal. So after the charges and negligent service we called Paul and parted ways amiacably. We had also noticed a lot of pooling water around our pool equipment. Our pool equipment is next to the AC unit. When I asked him about it, the guy who was servicing our pool told me he'd checked the equipment and nothing was leaking and that it must be the AC. So after we had cancelled with Beachfront I had my plumber look at the AC. He said the AC was fine and it was clearly the pool heater leaking. Once we hired a new pool serviceman he told us our salt was too high. Then figured out it was our chlorinator that needed replacing. I think it had needed replacing for a while because our automation system had been saying low salt. But Beachfront Pools had just been pouring more salt into it without checking the chlorinator. They were making our pool water way too salty. Apparently the chlorinator needs to be changed often but the heater now needs to be replaced way earlier than it should be. It's only just outside of the warranty windowand it still heats great! Both the new pool serviceman, and the product representative said that the heater is leaking because the pH on our pool water has been off for so long. So now I've not only overpaid Beachfront for years of negligent service but I'm also in over $5000 in repairs because of their negligence. Hope this can save someone else from our mistakes.

    Had one of the owners come to our property while Our pool…read morewas being replastered. He checked everything out and we had a great conversation. He assured me that they can service my pool and do the startup. I stayed in touch with all of them through the plastering phase to keep them updated on when to come out. They assured me multiple times all was well and they would be ready to go. All the other pool companies I turned away after we agreed on price. On the day of startup, they came out and he spent a ton of time on the phone in the front of my house. No update from him, he left and I get a random text that my house is out of their service area. I told them that makes no sense as we have been in touch for a few weeks and I was assured all was good. They opted to not take my pool on and told me to contact someone else. They said they wouldn't charge me for the visit like they did me a solid..i just don't get it. All I asked was for transparency and not leave me in a position to call back the other pool companies and ask for a quote. I said, since you made a mistake and it's out of your service area, can you just finish the start up you promised me and I'll find another company to do the maintenance. They said no. After a pool is replastered, it's a crucial time to ensure everything is moving in the start up phase and they almost screwed me over. It's an expensive project to replaster and none of that was taken into account on their behalf. I'm very disappointed in how this company handled my service.

He was upfront on what would be expected of me and what he would do weekly/yearly. I had no idea what a pool needed. He explained that the pump needs to be run at least 6 hours a day to circulate the water. He would come weekly to test the water, clean the pool and check the small filter (and probably other things I forgot about). Yearly, he puts conditioner in (he explained what it does but I can't remember). A couple months ago, my pool started to turn slightly green. He put some other chemicals in to help it. But it didn't work. So he checked my big filter and told me it needed a cleaning . He and another guy came that weekend and cleaned it. After he was done, he texted and explained everything he did to the filter and pool and what I needed to do to make sure the water clears up. By the next day, the pool started to clear up. Within a couple days, it was back to normal. He's very responsive and helpful. He comes when I'm at work so I usually text him if I need anything or have questions. He speaks English but is also fluent in Korean. Totally hire this guy/company if you need a pool guy!
