Our pool closing service includes complete water balancing, specialized winterization chemicals, thorough equipment shutdown, and professional cover installation. We handle both inground and above ground pools throughout Sea Cliff and Nassau County. In Sea Cliff, we typically schedule closings from mid to late October when nighttime temperatures consistently drop below 50 degrees. This timing is crucial – close too early and you waste swimming time, wait too long and you risk freeze damage. We also provide equipment winterization for heaters, pumps, and filtration systems, plus proper storage recommendations for removable accessories. Every closing includes a final inspection to ensure your pool is completely protected for winter.
