Protecting Your Pool Through Winter: Closing Tips for Toronto Pools

As the vibrant days of summer and autumn start to fade and Toronto’s cooler months settle in, it’s time to think about something that many pool owners often overlook: proper winter care for your pool. A little preparation now can save you from costly repairs in the future and ensure your pool is ready to dive into once again come spring.

Here’s A Simple Step-by-Step Guide to Help You Protect Your Pool Through the Winter

Closing your pool properly is important for several reasons which we’ll outline in the step-by-step guide below, but if you ever have any further questions or concerns about your pool, always consult with a professional.  

1. Why Winterizing Your Pool Matters

While you may be a busy homeowner, your pool cannot be forgotten about until spring even though the last swim of the season is over. Leaving your pool exposed to the elements can cause serious damage, especially in Toronto where winters bring freezing temperatures, snow, and ice, all of which can wreak havoc on your pool’s infrastructure if it’s not properly winterized. From cracked pipes to damaged liners, the cold can be brutal on a pool that isn't prepared for it.

2. Clean & Balance the Water Before Closing

Before you even think about covering the pool, make sure it’s cleaned thoroughly. Skim the surface, vacuum the bottom, and scrub the walls. Any debris left in the pool can create algae or other unsightly problems when the weather warms up again.

Next, balance the water’s pH, alkalinity, and calcium hardness. Ensuring the water chemistry is in check can help prevent corrosion, staining, and scaling during the months your pool isn’t in use.

3. Lower the Water Level, But Not Too Much!

One common mistake pool owners make is draining the pool too much for the winter. While it’s important to lower the water level to account for any rain or snowfall, leaving too little water can cause the liner to shrink or tear. You should drain the water just below the lowest return in most cases, to allow room for expansion in the case of ice forming, while still maintaining enough pressure on the walls to prevent damage.

4. Protect Your Equipment

Your pool equipment (pumps, filters, heaters, etc.) also needs protection from freezing temperatures. Drain any water from these components and store them in a dry, sheltered space if possible. If you can’t move the equipment indoors, be sure to cover it securely with a weatherproof cover. Next, add antifreeze to any pipes and plumbing lines that can’t be completely drained to prevent them from freezing and cracking.

5. Invest in a Quality Pool Cover

Your pool cover will be your best friend through the winter months. A quality cover can prevent debris from falling into the pool and protect it from snow, ice, and freezing temperatures. Make sure the cover is secure and fits snugly around the pool. It’s also worth considering a safety cover if you have kids or pets. These covers are not only durable but can provide peace of mind that no one will accidentally fall into the pool during the off-season.

6. Check on Your Pool Throughout the Winter

Once your pool is closed up for the winter, it doesn’t mean you can forget about it entirely. Check on it periodically to ensure that the cover remains intact and there’s no build-up of debris or excess water that could damage the cover or pool structure.

A Well-Protected Pool Saves You Time & Money

Properly preparing your pool for Toronto’s harsh winter conditions is key to protecting your investment and making reopening a breeze when warmer days return.
