Proper pool closing is one of the most important services for homeowners in regions that experience freezing winter temperatures. In New York and the Northeast, pools are typically closed during the fall once water temperatures have cooled and the swimming season has ended. However, choosing the right closing date involves more than simply watching the calendar.

Why Does Water Temperature Matter?

Closing a pool while the water is still warm can increase the likelihood of algae growth beneath the winter cover.

Waiting too long, on the other hand, can expose pool plumbing and equipment to freezing temperatures.

A common guideline is to close the pool once the water consistently reaches approximately 60–65°F, while ensuring winterization is completed before freezing conditions create a risk of damage.

What Happens During a Professional Pool Closing?

• Our pool closing and winterization service involves:
• Vacuuming and cleaning of the entire pool, removing any debris.
• Testing and balancing water chemistry
• Deep cleaning of the filtration system
• Removing accessories and preparing the pool
• Clearing and protecting plumbing lines
• Draining water from equipment that could freeze
• Storing any equipment that is needed
• Protecting the skimmer and return fittings
• Installing and securing the winter cover

The exact procedures depend on the pool's design, plumbing, equipment, and cover system.

Why Is Proper Winterization Important?

• Water expands when it freezes. If water remains trapped inside pool plumbing, pumps, filters, or heaters, freezing temperatures can cause significant and expensive damage.
• Improperly winterized pools may experience cracked plumbing, damaged equipment, leaks, or difficult spring openings.
• Scheduling your winterization before closing season becomes busy helps ensure your pool receives the attention needed to remain protected throughout the winter.
• Taking the time to properly close your swimming pool in the fall can prevent unnecessary expenses and make reopening easier in the spring.
