Mario came to my house and took care of business for my pool. After just one visit the pool looks better than it has in quite some time. His rates are better than most and he’s down to earth.

Mario did a great job replacing my pool filter. His expert recommendations and efficient replacement of my pool filter, along with impeccable plumbing work, exceeded my expectations. Mario’s reasonable pricing adds to the overall satisfaction.

The man has messed up my pool he has not showed up. He only responds to text messages when he feels like it now my pool is completely black because he keeps saying he’s gonna show up and never does very very unprofessional. I would give him zero stars if I could. Now is gonna cost me way more to get my pool back the way it was when he initially touched my pool, very disappointed. He should not be allowed to have a professional platform when he’s not doing professional work I’m angry.

Details: Cleaning and Maintenance • In-ground pool • Pool water is clear • I do not need my pool drained • Every other week

People like you is why i don't like helping out. First of let's get the facts straight. your pool was destroyed before I started i have all text and pictures to prove it. second wen I did get your pool going everything was fine buy you wanted me to service pool every other week even after I recommend that is not good idea you still said every other week.. 3rd i show up and your land lord doesn't fix the power outlet so I can't even turn on the pool and it takes 2 and a half weeks before you tell me it's ready. you expect me to use all my chemicals on your pool wen I didn't cause that. no not doing it anymore. then of course the winds came. I have my business for a reason but I don't deal with people like you. trying to get away with not paying for what you should pay for.
