How do Ottawa's ice and snow conditions affect garage doors and what maintenance should I do each winter?

Ottawa's winters are tough on garage doors in ways that homeowners in milder climates never have to think about. The combination of heavy snowfall, ice buildup, road salt, and extreme cold creates a set of challenges that require specific seasonal attention if you want your door to operate reliably from November through March.

The most immediate winter issue is ice forming along the bottom of the door. When snow melts during the day and refreezes overnight, it can bond the bottom seal to the garage floor or driveway. If you hit the opener button in the morning without checking, the opener tries to lift a door that is literally frozen to the ground. This puts enormous stress on the opener motor, the springs, and the bottom section of the door. In serious cases it can strip the opener gear, stretch or snap a spring, or tear the bottom seal right off the door. Before opening your garage door on cold mornings after a freeze-thaw cycle, take a look at the bottom edge. If it is frozen down, pour some warm water along the seal or use a rubber mallet to gently break the ice bond before hitting the button.

Road salt is the other big enemy. If your garage faces the street, salt spray from passing cars and plows coats the bottom panels of your door all winter. On steel doors, salt accelerates rust formation, especially at any spot where the paint is chipped or scratched. On the hardware, springs, and tracks, salt causes corrosion that shortens their lifespan and makes everything operate less smoothly. The best defence is to rinse the door and tracks with fresh water two or three times during the winter, ideally during a mild stretch when temperatures are above zero.

Before winter arrives each year, you should complete a basic maintenance routine. Start by lubricating all moving parts, including the springs, hinges, rollers, and track bearings, with a silicone-based lubricant. Do not use WD-40 for this because it is a solvent, not a long-term lubricant. Silicone spray stays effective in cold temperatures where petroleum-based products thicken and become useless. Next, inspect the weatherstripping around the full perimeter of the door. The bottom seal should be flexible and make full contact with the floor. The side and top seals should press firmly against the door with no visible gaps. Replace anything that is cracked, hardened, or compressed flat.

Check the balance of the door by disconnecting the opener and lifting the door manually to about waist height. Let go carefully. A properly balanced door should stay in place or drift down very slowly. If it drops quickly or feels very heavy to lift, the springs need adjustment. Do not attempt spring adjustment yourself because the tension involved is dangerous.

Also inspect the safety sensors at the bottom of the door tracks. Snow and ice can knock them out of alignment, and road grime can cloud the sensor lenses. Wipe them clean and make sure both lights are steady, not blinking. Finally, tighten any loose bolts on the tracks, hinges, and brackets. Metal contracts in the cold, and fasteners that were snug in summer can work loose by January.

This full maintenance routine takes about 30 minutes once a year and can prevent most of the winter-related failures that lead to emergency service calls in Ottawa.
