How to Prepare Your Pool for Closing Season

As summer comes to an end, it’s time to start thinking about closing your pool for the winter season. Properly preparing your pool for closing ensures that it stays in good condition and ready for use when warmer weather returns. In this blog post, we will discuss the steps to take to prepare your pool for closing season.

1. Clean the Pool

The first step in preparing your pool for closing season is to thoroughly clean it. Remove any debris, leaves, and dirt that may have accumulated on the surface and bottom of the pool. Use a skimmer net and pool vacuum to reach all corners and remove any remaining debris. Cleaning the pool ensures that no contaminants are left behind that could affect the water quality during the winter months.

2. Balance the Water Chemistry

Before closing your pool, it is crucial to balance the water chemistry. Test the pool water and adjust the pH, alkalinity, and sanitizer levels to the recommended ranges. Balancing the water chemistry helps prevent the growth of algae and bacteria during the winter months when the pool is not in use.

3. Shock the Pool

After balancing the water chemistry, it is time to shock the pool. Shocking the pool involves adding a large dose of chlorine or other oxidizing agent to destroy any remaining contaminants in the water. Follow the manufacturer’s instructions on the pool shock product for proper dosage and application. Shocking the pool helps ensure that the water remains clean and clear during the dormant winter period.

4. Remove and Store Pool Accessories

Before closing your pool, remove and store any pool accessories, such as ladders, diving boards, and pool toys. Clean and dry these accessories thoroughly before storing them in a dry location. Storing the pool accessories properly prolongs their lifespan and prevents any damage that may occur during the winter months.

5. Lower the Water Level

Lowering the water level in your pool is essential to protect it from freezing during the winter season. Use a submersible pump or a pool cover pump to lower the water level below the skimmer opening. This prevents any freezing water from damaging the pool equipment or causing potential cracks in the pool walls or floor.

6. Drain and Winterize the Pool Equipment

Next, drain and winterize the pool equipment, such as the pump, filter, and heater. Follow the manufacturer’s instructions for proper winterization procedures. Drain the water from the equipment and ensure that there is no remaining water that could freeze and cause damage. Disconnect and store any hoses or pipes, and use winterization plugs to prevent any water from entering the equipment during the off-season.

7. Install a Pool Cover

Finally, install a pool cover to protect your pool during the winter months. Choose a high-quality, durable pool cover that is designed for winter use. Make sure the cover fits properly and securely over the pool, completely sealing it. A well-fitted cover prevents debris from entering the pool, reduces evaporation, and maintains the water’s chemical balance.


Properly closing your pool for the winter season is crucial for maintaining its condition and ensuring longevity. The steps mentioned above, including cleaning the pool, balancing the water chemistry, shocking the pool, removing and storing pool accessories, lowering the water level, draining and winterizing the pool equipment, and installing a pool cover, are essential for a successful pool closure. By following these steps, you can protect your pool from winter damage and ensure that it is ready for enjoyment when the swimming season returns.
