How to Close Your Pool

As the vibrant days of summer slowly make way for the crisp beauty of fall, it’s time to start thinking about winterizing your pool. Properly preparing your pool for the colder months ensures its longevity and makes the process of reopening in spring much smoother. Bremner Pools guides you through winterizing your pool, safeguarding your investment, and easing your mind.

Step 1: Clean and Balance

Before you begin the winterization process, ensuring your pool is as clean as possible is crucial. Skim the surface, vacuum the bottom, and brush the walls to eliminate debris. Then, balance the water chemistry by checking the pH, alkalinity, and calcium hardness levels. Properly balanced water prevents scale buildup and equipment damage during the winter months.

Step 2: Shock the Pool

Give your pool one last shock treatment to kill lingering bacteria or algae. Choose a non-chlorine shock or a winterization-specific product to prevent chlorine damage to your pool liner. Make sure to follow the manufacturer’s instructions for dosage and application.

Step 3: Lower the Water Level

Lower the water level to protect your pool from freezing and potential damage. Drain the pool water to a level slightly below the skimmer. This prevents ice from forming and potentially damaging skimmers, pipes, and other equipment.

Step 4: Winterize the Plumbing

Properly winterizing the plumbing is crucial to avoid freeze damage. Blow out the plumbing lines using a shop vacuum or a compressor to remove any water. Plug the return and skimmer lines with winterizing or expansion plugs to keep water out.

Step 5: Add Winterization Chemicals

Add winterization chemicals to the pool water to keep it clean and balanced during the winter months. A winterization kit typically includes chemicals like algaecide and a stain and scale inhibitor. Follow the kit instructions to add the correct amounts.

Step 6: Cover Your Pool

Invest in a high-quality pool cover to protect your pool from debris, harsh weather, and UV rays. Choose a cover that fits snugly and provides adequate protection. A properly fitted cover also prevents the accumulation of stagnant water on its surface.

Step 7: Maintain Throughout Winter

Though your pool might be closed for the season, it still requires some maintenance during the winter. Regularly remove debris that accumulates on the cover, check the water level to ensure it’s not too high or low, and inspect the cover for any signs of damage. Additionally, if you live in an area with heavy snowfall, consider using a cover pump to prevent excessive weight from accumulating on the cover.


Winterizing your pool is a vital process that ensures your pool’s longevity and minimizes potential damage caused by freezing temperatures. By following these comprehensive steps provided by Bremner Pools, you’ll be well-prepared to face the winter months, knowing that your pool is protected and ready for a smooth reopening come spring. Remember, a little effort now goes a long way in preserving the beauty and functionality of your pool for years to come.
