Pool Closing Season: When and How to Get Started

Sunrise Premiere Pool Builders Pool Closing

It’s getting close to pool closing season, so it’s time to start planning ahead.

As summer winds down, it is time to start planning your pool closing. Preparing early helps protect your pool from freezing weather, prevents damage to equipment, and makes reopening easier when warm weather returns. Don’t wait until the last minute to begin the process of getting your pool ready for the cold season. A smooth closing process leads to a smooth reopening next spring, so it’s always a good idea to put in the time and effort to do it right.

When Is the Best Time for Pool Closing?

The ideal time for pool closing depends on local weather and water temperature. In most areas with cold winters, pools are typically closed between September and November. However, you should avoid closing too early.

Wait until the pool water consistently stays below 65 degrees Fahrenheit. Cooler water slows algae and bacterial growth, helping the pool remain cleaner throughout the winter. Closing while the weather is still warm can create cloudy, green water beneath the cover.

On the other hand, it’s also not a good idea to wait until freezing temperatures arrive. Schedule your pool closing early enough to prepare the water, equipment, plumbing, and cover before the first hard freeze.

How to Prepare Your Pool for Closing

A successful pool closing begins several days before the cover goes on. Start with these important steps:

Clean the Pool

Brush the walls, vacuum the floor, and remove leaves and debris. Empty the skimmer and pump baskets so organic material does not sit in the pool all winter.

Test and Balance the Water

Check the pH, total alkalinity, calcium hardness, and sanitizer levels. Properly balanced water helps prevent corrosion, staining, and scale buildup during the off-season.

Add Winterizing Chemicals

Depending on your pool, winterizing chemicals may include shock, algaecide, stain preventer, and other treatments. Always follow product directions and avoid mixing chemicals directly.

Lower the Water Level

Some pools require the water level to be lowered below the skimmer or return lines. The correct level depends on the type of pool and winter cover being used.

Protect the Plumbing and Equipment

Water must be removed from the plumbing lines to reduce the risk of freezing and cracking. The pump, filter, heater, chlorinator, and other equipment should also be drained and prepared according to manufacturer recommendations. Winter plugs and pool-safe antifreeze may be needed in certain systems.

Install the Winter Cover

A secure winter or safety cover keeps leaves, animals, and other debris out of the pool. Inspect the cover for damage and make sure it is properly anchored.

How Professional Pool Closing Can Help

Pool closing involves more than adding chemicals and placing a cover over the water. A missed step can lead to cracked pipes, damaged equipment, stained surfaces, or expensive repairs.

Our pool professionals know how to winterize each component correctly and identify maintenance concerns before they become bigger problems. Professional service can also save you time and help ensure that your pool is ready for a smoother spring opening.

Pool closing appointments can fill quickly as cooler weather approaches. Contact Sunrise Pools early to schedule your service and protect your investment throughout the winter.
