There isn’t necessarily a specific time of year that is best to buy a garage door. However, there are a few factors you may want to consider when deciding when to make your purchase:

1. Seasonal demand: Many homeowners tend to replace their garage doors during the spring and summer months when the weather is mild and pleasant. This may result in increased demand for garage doors during these times, which could affect pricing and availability.
2. Sales and promotions: Some garage door manufacturers and retailers may offer special sales and promotions during certain times of the year, such as around major holidays like Canada Day, Labour Day, or Black Friday. Keep an eye out for these deals if you’re looking to save some money.
3. Installation scheduling: If you plan to hire a professional installer to put in your new garage door, you may want to consider their availability and schedule. Some companies may be busier during certain times of the year, which could affect how quickly they can install your new door.

Ultimately, the best time to buy a garage door is whenever you need it or are ready to make the investment. Do some research, compare prices and options, and make a decision that works for you and your budget.
