Sweeney's Pool Service, Inc
Sweeney's Pool Service, Inc
Sweeney's Pool Service, Inc. is a premier swimming pool service company dedicated to residential clients in Suffolk County, providing exceptional service for over 10 years. Owner Kenneth Sweeney began his journey in the swimming pool industry in 2007, gaining valuable knowledge and hands-on experience while working for several major companies. During this time, he listened to customers and identified common concerns, particularly regarding communication barriers and reliability. In the spring of 2012, Kenneth decided to address these issues by founding his own company, Sweeney’s Pool Service, Inc. His mission was straightforward: to listen to customers and deliver dependable service. From day one, the company emphasized core business values, starting with customer interactions in the office. Staff members are trained to answer calls with a positive attitude and to genuinely listen to homeowners' needs. By taking the time to diagnose problems and provide effective solutions, they create a better customer experience. The service technicians at Sweeney’s are fully trained and licensed to handle everything from basic pool cleaning to complex pool heater repairs and custom in-ground pool builds. With a committed team, Sweeney's Pool Service, Inc. has experienced continued success and expanded its customer base over the years. Each year, they actively listen to customer feedback to enhance their services and better serve the community. As Kenneth Sweeney puts it, “Professionalism and reliability are the keys to success.”
"⚠️ Read before deciding to go with this company! ⚠️ I regret ignoring the negative reviews when I chose Sweeney’s to install my pool. They damaged my property, have taken no accountability and have chosen a vindictive approach to the matter. I urge you to read my experience, and the other negative reviews posted, and think about whether you can trust them to work at your home. They excavated my yard at the end of November 2024 during heavy rain, then left the ground unbackfilled for 12 days. This left my concrete stairs unsupported, with the footing exposed (see photos) and the stairs became detached from my patio. When I contacted Sweeney’s with photos, they relied on their mason affiliate, Devin of Flawless Masonry, who stated the stairs were improperly constructed. THEY DID NOT ASSESS THE SITUATION IN PERSON, NOT THEN OR EVER! I spoke with Devin prior to excavation and he assured me that the stairs were ok and they would not need additional support, I have the text message proof. I never heard from Ken Sweeney directly; however, communication with Reed Communiello, the project manager, on behalf of Sweeney’s has been extremely disheartening. An agreement was discussed where Devin would resolve the situation at cost, at our expense. I received an email from Sweeney's attorney, which included a non-disparagement clause. I agreed to not speak about the issue with the stairs but I felt it left me without recourse should the remaining work not be completed satisfactorily. I agreed to the terms however, Sweeney’s contacted the Town of Hempstead inquiring whether my patio and staircase were built without permits, which unbeknownst to us they were (built prior to 1996; purchased the home in 2018). Sweeney’s rescinding the agreement. They think a homeowner does not have rights when structures are not permitted but that is not the case. My real estate attorney attempted to reach out to them through their attorney, but to no avail. I attempted to retrieve liability insurance. They submitted the only insurance required by the ToH, worker’s compensation, under a different company, JAS Aquatics. They also changed the Contractor Information Form listing the contractor as JAS Aquatics. When I questioned this, I was told “The entities doing the work are valid with the insurance submitted.” I am unsure if Sweeney’s does hold liability insurance or not. I hired a civil and structural engineer. The engineer's report confirmed that the structures were built properly, despite lacking permits. He noted that Sweeney’s was negligent for not supporting the stairs while leaving the footing exposed for 12 days, in which 6 of those days it rained. Sweeney’s dismissed the report—again, without ever coming to assess the situation in person. I am left with no choice but to demolish and rebuild the stairs myself. Due to their spiteful actions of reporting me to the ToH, I now need to have plans drawn up to obtain permits for my patio, stairs and enclosed entryway before any further work can be done. This not only delays the process, it escalates cost. My property has been left in disarray for over a month. I paid in full for the excavation process, yet my deep end is still not dug out. My gate has been disassembled and left that way, my existing pavers were destroyed during the excavation, and my back fence became uneven due to being left without backfill for 20 days. I had to request for them to come back to do the backfill so the fence didn’t collapse. There is also a pile of boxes on my driveway—some empty and others filled with equipment. If this review helps even one person avoid a similar experience, it will be worth it. The stairs existed for at least 30 years without any issue and only detached once Sweeney’s left the exposed concrete footing unsupported for 12 days in the rain. My situation may be unique, but the lack of accountability from Sweeney’s is not, as you can see from other reviews. You do not want to find yourself on the wrong side of Sweeney’s, because once you do they will treat you with utter disregard. Choose wisely!"

Sunshine Solar Technologies specializes in solar pool heating and solar hot water solutions for homes and businesses in New York, New Jersey and Connecticut. Call us today for a free solar site analysis!
"Totally dissatisfied with the warming effects of the solar heating unit they installed. They never calculated the amount of sun that would reach the solar units and instead claimed that the pool would be warmed to 80 degrees plus. Well of course it would when the outside temperatures were in the 80s. But of course using the pool in June and September meant very cool water temperatures. I now need to replace my propane heater for next year. What a waste of money!"
