Why Garage Doors Freeze Shut in Caledon Winters
Winter can be tough on a lot of things, and garage doors are no exception. Around Caledon, cold weather tends to stick around for months, making everyday tasks like pulling out of the garage feel a bit more complicated than usual. One of the most common complaints we hear is that garage doors freeze shut overnight. No one wants to deal with that first thing in the morning.
Over the years, we’ve noticed that some garage door installations in Caledon homes handle the cold better than others. But even the best system can get stuck if the conditions are right. Knowing what causes doors to freeze helps you stay one step ahead of the problem, especially when the temperatures drop and moisture starts to settle in all the wrong places. With over 35 years of experience in residential garage door installation and repair across Southern Ontario, we have seen how winter conditions affect garage doors in Caledon.
What Really Happens When Your Garage Door Freezes
When it’s cold out, garages don't always stay dry. Snowmelt from your car or frost in the air finds its way to the bottom edge of the door. When the temperature goes below freezing, that moisture turns to ice, often sealing the garage door shut.
There are a few ways this freezing can become a real issue:
• Water seeps under the weather stripping and then freezes, bonding the seal to the ground
• Ice collects between door panels, making them harder to move or causing them to jam
• Automatic openers can strain against the stuck door and damage the motor or tracks
Even just a thin layer of ice along the edge can block the opening motion and cause a lot of wear on the system if forced. It may look harmless but can be enough to throw off sensors or slow down parts that rely on smooth movement.
Common Spots Ice Builds Up
Not all parts of a garage door system are equally vulnerable to freezing. Some areas tend to hold onto moisture longer or sit right in the path of snow and runoff. These are the spots where issues tend to start:
• The weather strip across the bottom of the door, especially where it touches wet concrete
• Metal rollers or tracks exposed to exterior air, which stiffen or develop frost in extreme cold
• Garage floors that slope toward the opening, guiding water right to the base of the door
When moisture keeps returning to these areas and there’s no warm air to dry things out, it creates the perfect setup for freezing. Ice starts in small patches and builds over time unless checked.
Why Recently Installed Doors Can Still Freeze
It might seem like a brand new door should be problem-free, but new systems aren't always immune to cold-weather trouble. In fact, doors that are freshly caulked and sealed tight sometimes hold onto more indoor humidity. That moisture, when trapped during low temperatures, can freeze just like water from outside.
It’s common for garage door installation in Caledon homes to have heavy insulation and tight seals. But those advantages can still turn into problems if drainage isn’t working well or if heat doesn’t circulate inside the garage space. Here's why even new doors can freeze shut:
• New seals hold warm, damp air, which clings to cold surfaces and turns to frost
• Extra insulation means less airflow, so condensation does not have a way to escape
• Poor garage drainage pushes meltwater straight to the edge of the frame
Doors might be installed properly but still need time to "settle in" and find balance with the home’s heating and airflow patterns. Until then, winter can create brief periods where freezing is more likely.
Helpful Winter Habits That Keep Doors Moving
Staying ahead of the freeze is possible with some small changes to how you care for your garage during colder months. While you can't stop snow from falling or temperatures from dropping, small habits go a long way toward minimizing the chance of getting stuck.
These habits can make things smoother:
• After it snows or sleets, gently clear slush along the outside of the door using a plastic shovel or brush
• On dry afternoons, wipe down the seals around the frame and door base with an absorbent cloth
• Open the garage once or twice a day to let dry air in and reduce moisture buildup
• Keep an eye on driveway grading so water isn’t flowing directly toward the door seam
Even if some ice forms, these steps can reduce how often it happens and lower the risk of wear or broken parts from trying to open a frozen door.
Peace of Mind for Cold Mornings Ahead
When your garage door moves how it should, it keeps daily life running without stress. Getting blocked in or stuck outside on a cold morning is frustrating and totally avoidable in most cases. We’ve seen how winter conditions affect both older models and newer ones, especially around Caledon, where the cold likes to linger longer. As a family-owned and operated company based in Mississauga, we serve Southern Ontario’s Greater Toronto Area, including Caledon, and provide 24/7/365 emergency garage door service when doors fail in harsh weather.
By understanding which parts of the system are most affected, you can keep an eye on trouble before it snowballs. A frozen door isn’t just about bad luck. It’s usually the result of a few small factors lining up at the wrong time. Staying alert to freezing spots and changing some habits around snow, drainage, and daily use makes a big difference. Garage doors should keep moving no matter the weather. When they do, the rest of your day gets off to a better start.
