Home Improvement


As winter approaches and temperatures drop, it becomes crucial to properly prepare your swimming pool for the cold months ahead. Taking the necessary steps to winterise your pool can help prevent major damage caused by freezing temperatures, ensuring that your pool stays in optimal condition. Not only does winterisation protect your pool, but it also makes the process of reopening the pool much easier when the warmer season returns.

This straightforward and comprehensive guide will walk you through the step-by-step process of effectively winterising your pool, covering everything from draining and cleaning the pool to adding the right winter chemicals and securing the pool cover. By following these detailed instructions, you can rest assured that your pool will be well-protected during the winter months, ready to be enjoyed again when the weather warms up.

Cleaning Your Pool

To begin the pool cleaning process, start by meticulously removing any debris present, such as leaves and insects, using a pool skimmer. Take your time to ensure that no remnants are left behind. Next, take a pool brush and thoroughly scrub the sides and bottom of the pool, paying extra attention to areas prone to algae and other buildups. This meticulous cleaning will help eliminate any stubborn dirt or grime. Finally, complete the cleaning process by vacuuming the pool, ensuring that every nook and cranny is thoroughly cleaned, leaving your pool sparkling and pristine.

Balancing The Water Chemistry

Before you close your pool for winter, it’s important to balance the water chemistry. This step helps prevent algae growth and scale buildup. Use a water testing kit to check the pH, alkalinity, calcium hardness, and chlorine levels. Adjust these levels as necessary following the recommendations provided in your water testing kit.

Lowering The Water Level

To prevent freezing damage to your pool and its equipment, it is important to lower the water level. The exact water level to lower will depend on the type of pool cover you are using. For mesh covers, it is generally recommended to lower the water level below the skimmer mouth. However, for solid covers, it is advised to lower the water level approximately 18-24 inches below the pool edge. By following these guidelines, you can ensure that your pool and its equipment are well-protected during freezing temperatures.

Protecting Your Pool Equipment

Next, as part of your winter pool maintenance routine, it is important to turn off your pool pump and heater. This will help protect them from potential freezing damage. Additionally, draining the water from your pump, filter, pipes, and other pool equipment is crucial to prevent any water from freezing and causing damage. It is recommended to carefully follow the manufacturer’s instructions to ensure proper draining and avoid any mishaps. Lastly, for added protection, storing removable parts indoors during the winter months is a wise precautionary measure to prolong the lifespan of your pool equipment.

Covering Your Pool

To ensure the utmost protection for your pool during winter, it is highly recommended to invest in a high-quality, winter-proof pool cover. This robust cover should be securely fastened to effectively shield your pool from debris, as well as safeguard it against the harsh elements of winter. Additionally, besides its functional benefits, pool covers also serve as an important safety feature, significantly reducing the risk of accidental slips or falls into the pool. By implementing this comprehensive approach to pool maintenance, you can have peace of mind knowing that your pool is well-preserved and safe throughout the winter season.

Regularly Checking Your Pool During Winter

Throughout the winter, make sure to regularly check on your pool. Monitor the water level and chemistry, and adjust if necessary to maintain a balanced state. Inspect your pool cover for damage or debris buildup – if snow accumulates on the cover, gently remove it to prevent excessive weight strain. Moreover, ensure your pool cover remains tightly secured. Implementing these practices can help guarantee your pool’s readiness for seamless reopening when the warm season returns.

Dealing With Rainwater Accumulation

During winter, it’s common for rainwater to accumulate on top of your pool cover. It’s crucial to remove this water promptly, as excessive weight can damage the pool cover or cause it to sag into the pool. You can use a cover pump to drain the excess water. Remember to carefully operate the pump to avoid puncturing the cover.

Removing Standing Water from Solid Covers

If you’re using a solid pool cover, standing water can collect on its surface. This not only poses a drowning hazard for small animals but also increases the wear and tear on the cover itself. A pool cover pump can be used to remove this standing water, thereby extending the lifespan of your cover.

Taking Care of Your Pool Cover

Your pool cover needs care during the winter months to keep it in good shape. Regularly clean and inspect it for signs of damage and make repairs as soon as you notice any. Replace the pool cover if it becomes too worn or damaged. This will help ensure that it effectively protects your pool throughout the winter.

Keeping Your Pool Area Safe

Even though your pool will not be in use, it’s important to keep the surrounding area safe. Clear away any snow or ice from the pathways around the pool to prevent slips and falls. Also, secure any pool toys, furniture, or accessories that could become a hazard in high winds or storms.


It’s important to keep in mind that every pool is unique, with its own set of requirements and characteristics. So, when it comes to winterising your pool, it’s crucial to tailor the steps to suit the specific needs of your pool. By doing so, you can ensure comprehensive protection for your pool investment and pave the way for a smoother spring opening. Taking the time to properly winterise your pool will involve tasks such as draining the water to the appropriate level, cleaning and treating the pool, covering it securely, and implementing any necessary maintenance procedures. These steps, when followed diligently, will not only safeguard your pool but also contribute to its longevity and optimal performance. So, embrace the opportunity to give your pool the care and attention it deserves, and you’ll reap the benefits in the seasons to come.
