We were introduced to advantage li as a former Rocco pool's client. Unsure of the transition we learned quickly how advantage values their clients. We have family coming in and when our heater failed we were concerned due to cooler temperatures our plans would be comprised. We called advantage li and the owner immediately answered our concerns, created a solution and had himself and his crew there within a few days. He carefully explained the process; costs and how the new system would work Throughout the process he kept in touch and when he had questions after install he was quick to respond. We would recommend to call advantage for all your pool needs.

This company was ok at first. Periodically missed my regular appointments and I had to call to see what happened several times. I also had to request for certain things to be done for pool that they should have known to do like scrubbing the liner, adjusting the timer with day light changes, etc. LAST STRAW: Team came to close my pool today, never cleaned the pool, put the cover on with a ton of leaves and debris in the pool. Left a mess with garbage and bags all around the pool. I called to request them to come back and close the pool properly which I was happy to pay for. THE OWNER said to me "We will credit you and not charge for the service" and would not send his crew back to fix it. He was rude and told me that I need to know how to maintain the pool and tell them what to do??? I am now left with a mess and a pool that will be ruined and permanently stained by Spring.

Response from Company:

This customer had called my secretary and was very rude to her. She did not request a pool cleaning before closing. In fact, she had canceled her cleaning for last week when she had called and started to yell and curse at my secretary. After that I got on the phone with her and told her if she was not happy with the service that we would not charge her. That wasn't good enough for her, either. She cursed at me and then hung up on me. After that, I had called her back and told her we would send somebody no problem, and we apologize for the misunderstanding, and we do over 300 pool closings a year and not all of them are cleaned before closing.

This company maintained our pool all summer long. The pool we have is a large gunite pool with salt water, it is hard to maintain and keep clear but they did it. If there was ever an issue or concern, Clinton responded himself within a few hours of contacting them. When our pool filter shorted out in a storm, they were there within 2 days with a new filter and gave us a fair price. The billing is easy, they give you a paper copy as well as send an email providing a bunch of payment options. The receptionist is efficient and someone always responds and answers. They send reminder emails before coming to service your pool. Communication and work is great.

Have used Advantage LI for closing and for opening my in-ground pool, and have never been disappointed. I am very happy with them, they are very professional and their work is of high quality. Clinton, the owner, is a genuinely nice guy and very knowledgeable about pools. Special thanks to Nico and his assistant who was a great pleasure to deal with and who did a great job. Thank you, team Advantage LI!

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
