What maintenance should I do on my garage door before each Ottawa winter season?

Your garage door needs a comprehensive pre-winter inspection and maintenance routine by early November to handle Ottawa's brutal freeze-thaw cycles and temperature swings that can reach 60 degrees Celsius between summer highs and winter lows. The combination of extreme cold, road salt, and repeated freeze-thaw cycles puts enormous stress on every component of your garage door system, making preventive maintenance essential rather than optional.

Start with the weatherstripping and bottom seal, which take a beating from Ottawa's harsh conditions. Check the rubber seals along the sides and top of the door frame for cracks, tears, or gaps that let cold air infiltrate your garage. The bottom seal is particularly critical — it prevents snow and salt-laden slush from entering under the door. Replace any weatherstripping that's hardened, cracked, or no longer makes good contact. Quality replacement weatherstripping costs $50 to $150 depending on your door size, but it prevents much more expensive problems like frozen door tracks or salt damage to your garage floor.

Lubricate all moving parts with winter-grade lubricant — this is absolutely critical in Ottawa where temperatures regularly drop to -25 degrees Celsius or colder. Use white lithium grease or synthetic garage door lubricant on all hinges, rollers, tracks, and springs. Avoid WD-40 or penetrating oils, which can thicken in extreme cold and actually make operation worse. Pay special attention to the torsion springs above the door — these are under enormous tension and work harder in cold weather as the metal contracts. Apply lubricant to the spring coils and the bearing plates at each end.

Test your garage door opener's cold weather performance by operating the door several times and listening for unusual noises, jerky movement, or signs that the motor is straining. Cold weather makes garage door openers work harder, and many Ottawa homeowners discover opener problems during the first deep freeze. Check that your opener's force settings haven't drifted — doors that operated smoothly in summer may require adjustment as weather seals stiffen and components contract. If your opener is more than 10 years old, consider having it serviced before winter rather than waiting for a breakdown during a January cold snap.

Inspect the door panels and hardware for salt damage from the previous winter. Road salt is incredibly corrosive, and even small chips in the door's finish can lead to rust spots that spread quickly. Touch up any paint chips or scratches with matching paint, and check that all bolts and brackets are tight. Salt-laden moisture from vehicles can cause hardware to corrode and loosen over time.

Clean the tracks thoroughly and check for any debris, ice buildup from the previous winter, or bent sections that could cause binding. Ottawa's freeze-thaw cycles can cause small amounts of water to freeze in the tracks, and even minor ice buildup can prevent smooth operation or damage rollers.

One final critical check: ensure your garage door opener has a battery backup if you have an electric opener. Ottawa ice storms and winter power outages are real possibilities, and being unable to open your garage door during a power failure can leave you stranded or unable to access your home. Battery backup units cost $150 to $300 but provide peace of mind during Ottawa's unpredictable winter weather.

If you discover any significant issues during your inspection — worn springs, bent tracks, opener problems, or damaged panels — don't wait until the first blizzard to address them.
