What's Included in Professional Closing

Comprehensive 12-step closing process that covers equipment, chemicals, plumbing, and covers – nothing gets missed. The specialized equipment alone – like commercial air compressors for proper line blow-out – costs more than most homeowners want to invest for once-a-year use.

Here in the northeast (Long Island), we typically close pools around October. However, we recommend closing as late as possible so that the water temperature is lower (less chance of algae blooming under the cover when you close later).

In Oyster Bay specifically, homeowners face unique environmental conditions that require specialized knowledge. Maintaining a pool can be challenging, especially with the unique weather and environmental conditions in Oyster Bay, NY. That’s why we use the latest equipment and techniques to ensure your pool is always ready for use.

Most of our customers close the pool in the September to October time frame. The kids are back in school, no one is using the pool, the water is getting chilly, and oh no, here come the leaves. If the pool isn’t getting much use, we highly recommend closing and covering your pool before the leaves start falling. Falling leaves and acorns are a pain to continuously clean out of the pool and they can stain the liner if left under the cover for the winter, so best bet is to clean and close the pool before the leaves start falling off the trees. The exact timing depends on your specific situation – if you have a heater, you might extend your season into November. But once you know you won’t be using the pool anymore, it’s better to schedule early rather than wait until the last minute.
The most expensive mistakes happen when homeowners try to save money by doing part of the winterization themselves. For example, improper chemical balancing can cause staining and surface damage that costs thousands to repair. One of the most important steps is blowing out and plugging the lines. If this step is not done, or done improperly, the water in the pipes can freeze and expand over the winter when the ground gets cold, resulting in cracked pipes, cracked skimmers and broken heaters, which are very expensive to replace. A pool can freeze in just a few hours of sub-zero temperatures, with damage often starting in exposed pipes and spreading throughout the entire system. Unfortunately, most insurance policies don’t cover freeze damage, as it is considered preventable maintenance.
Pool closing costs $250 to $500 for an inground pool and $150 to $300 for an above-ground pool on average. Inground pools cost more to winterize than above-ground pools. The exact cost depends on your pool size, equipment, and specific needs. Professional winterization costs a few hundred dollars, while fixing winterization mistakes often costs thousands. When you consider the potential damage from improper winterization – cracked pipes, broken heaters, damaged pool surfaces – professional service is actually the most cost-effective choice. Most pool contractors charge between $75 and $100 per hour, and the process typically takes 2-4 hours depending on your pool’s complexity and features.
We don’t recommend partial DIY winterization because pool closing is a system – every step depends on the others being done correctly. The most expensive mistakes happen when homeowners try to save money by doing part of the winterization themselves. Even small mistakes like incorrect water level or improper cover installation can cause major problems. The specialized equipment alone – like commercial air compressors for proper line blow-out – costs more than most homeowners want to invest for once-a-year use. Even if you are comfortable opening the pool yourself, we suggest hiring a professional to close the pool. The risk of expensive damage far outweighs the small savings from DIY attempts.
