Closing your pool for winter entails comprehensive preparation that protects both the pool and its equipment from freeze damage. Your professional service will remove, clean, and store all removable components; apply a chemical shock to eliminate algae and bacteria; vacuum and deep clean the pool; lower the water level to protect the liner; drain and lubricate the equipment; test and balance the water chemistry; and secure the pool with an air pillow if required. This detailed process ensures long-term pool health and prevents costly repairs.

Your local climate determines the ideal time to close your pool for winter. In colder areas, closing in September or October, when temperatures consistently drop below 65° F, protects your pool and equipment from freeze damage. In warmer climates, you may extend usage until a genuine risk of freezing is present, but timely closure is essential to prevent structural and equipment damage.

When draining your pool for winter, your pool pro will lower the water only until it's a few inches to two feet below the skimmer to protect the liner and equipment. The average cost to drain a pool is $175 to $225. This precise drainage minimizes strain on the pool structure and avoids risks associated with a complete drain.
