"As a new swimming pool owner that has no knowledge of swimming pool at all, I was looking for a contractor to adjust the depth of the existing swimming pool and replace the pool liner. I compared quotes from different companies and decided to choose Sweeney's after I spoke the owner Kenny, even though his quote is higher than other companies, his team has helped me understand the basics of swimming pool and take care of the entire life cycle of pool maintenace. Sweeney's Pool company has provided excellent service from adjusting depth of pool, new liner installation, pool opening, cleaning, closing and winter watch service at reasonable price. Sweenye's Pool company is honest, reliable and customer friendly. They have totally transformed the old swimming pool to a 5-star swimming pool every age can enjoy."

"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."

"Alex& his team did an excellent job repairing extensive damage to our inground gunite pool & brick pool deck due to the recent blizzard & ice storm this past winter. The hydrostat needed replacement as well. All work was completed quickly, skillfully and on budget. One love pools is also going to be my pool maintenance company as well. Couldn’t be happier with the work, the workers & Alex the company owner. I recommend this company wholeheartedly."

"Very honest businessman with very fair pricing. I hired him based on previous reviews and am so glad I did. I had a compound pump problem with bad threads on a blown out fitting as well as a defective one way valve for the pool heater causing a return line restriction They figured it all out and I m back in business. I ll definitely call them again when needed"

"Kyle installed our semi in ground pool, workmanship was perfect. Kyle and his team were friendly and professional. He also is installing our pool cover. Kyle is very responsive, he lets you know when he’s coming and then shows up on time. A real pleasure to work with. I will be using him next summer for pool maintenance."

"we were referred to Suffolk Liners by Island Recreational. We originally were going with the company that built our in ground pool but we decided to go with Suffolk because they made our deal with them much more attractive. We are still impressed with the speed of the installation and the quality of the end product, these guys are clean courteous , and left no mess whatsoever. I've already recommended them to two of my friends and plan to recommend them in the future. The sales person was also very good. Thanks guys ,good job"

"We had John Joseph install our pool and redo our whole backyard. We also continue to use them for openings and closings. They return all call very quickly and have came for any problems that we have encountered. We would 100% recommend them. Nestor is amazing with his vision to accompany the pool."

FAQs for pool construction and installation projects in Mount Sinai, NY

Running a pool pump continuously significantly increases your monthly electricity expenses. With a single-speed pump, you might see costs toward the upper end of the average range, potentially reaching $150 per month depending on your pump's horsepower and local electricity rates. 

Variable-speed pumps would be more economical even with continuous operation, but would still increase costs above normal. However, 24/7 operation is rarely necessary for residential pools, as most require only eight to 12 hours of daily filtration.

Yes, LED pool lights provide substantial energy savings compared to traditional halogen fixtures. Industry data indicates LED lights are five times less expensive to operate than halogen alternatives, while providing equivalent or better illumination. Though LED fixtures often have a higher initial purchase price, the energy savings and longer lifespan make them a cost-effective choice for pool owners who enjoy nighttime swimming.
