BLOG The Ultimate Guide to Preparing Your Pool for Winter Jun 04, 2026

As the colder months approach, preparing your pool for winter becomes an essential part of pool maintenance. For pool owners, ensuring your investment remains in peak condition through the off-season is key. At Robertson Pools, we understand the importance of winterizing your pool effectively. Follow these essential steps to prepare your pool for winter and ensure it’s ready for a splashy return when the warmth returns.

The initial step in preparing your pool for winter involves a thorough cleaning. Vacuum the pool floor to remove any debris that may have settled over time. Skim the surface for leaves, bugs, and any foreign objects that may affect your pool's chemical balance. Cleaning your pool before winter reduces the likelihood of algae and prevents stains from forming over the long, inactive months.

Next, focus on balancing your pool’s water chemistry. Proper chemical balance is crucial to keeping your pool in good shape throughout the winter. Begin by checking and adjusting pH levels to be between 7.2 and 7.6. This helps prevent corrosion and scaling. Use a shock treatment to eradicate contaminants and algae spores. Once shocked, allow the chlorine levels to drop back down to normal before proceeding to the next steps.

Once the water chemistry is balanced, it's time to lower the water level in your pool. Drain the water to just below the skimmer or tile line to prevent freeze-related damages. This is especially important in regions susceptible to heavy frosts. By reducing the water level, you mitigate the risk of ice expanding and causing structural damage to your pool.

Covering your pool is arguably one of the most important steps in winter preparation. A high-quality winter cover can save you from numerous headaches by keeping debris out, maintaining water temperature, and reducing chemical evaporation. When selecting a cover, ensure it is durable and fits snugly to prevent wind from blowing it off. Consider using a pool cover pump to remove standing water, which can add weight and stretch the cover over time.

Winterizing your pool equipment is equally critical. This includes the filtration system, pump, heater, and any additional water features. Drain water from all equipment to prevent freezing and expansion. Store removable equipment in a dry, indoor space. For equipment that must remain outdoors, use pool antifreeze to protect the plumbing.

Monitoring the pool throughout the winter, although not frequently, is important. Regular checks for cover integrity and significant water loss are advised. Doing so can help you identify potential issues before they escalate, ensuring your pool remains in optimal condition for use when the next season arrives.
