Springs and cables stay with a technician. Source: https://garagedoorscience.com/blog/garage-door-winterizing-checklist-before-the-first-freeze · by rick · published 2026-10-02 You want your garage door to work on the first cold morning, not stop working on it. Here is what to check this fall, in the order that makes sense when you walk around the door. Most of it takes a few minutes and a rag. ## 1. Look at the seals Start at the bottom of the door. [Clopay says the bottom seal takes the brunt of snow and ice](https://www.clopaydoor.com/blog/post/blog/2025/12/01/insulated-garage-doors-for-cold-climates), and that weatherstripping can go cracked or stiff in a harsh winter. [Clopay's seal guide](https://www.clopaydoor.com/residential/buyingguide/garage-door-seals) says to look for cracks, tears, missing pieces, hardening and gaps between the seal and the floor or frame. If a seal no longer springs back, it is time to replace it. Our guide to [choosing a garage door weather seal](/blog/best-garage-door-weather-seal) covers the types. Clopay recommends early fall for the job, because mild weather helps the new seal stick. ## 2. Hinges and rollers Wipe off the dirt, then give the hinges and rollers a light spray of silicone lubricant. [Raynor](https://raynor.com/checklist-keep-your-garage-door-working-smoothly-this-winter/) says to use silicone or a product labeled garage door lubricant, and [Clopay says to keep it off nylon rollers and off the tracks](https://www.clopaydoor.com/residential/buyingguide/how-to-properly-lubricate-garage-door-components). Skip [WD-40](/blog/wd40-garage-door-lubrication). Do not spray the spring or anything attached to it; that is a technician's job, along with the cables and the brackets at the bottom corners. ## 3. Batteries in the remotes and the keypad [Raynor says](https://raynor.com/checklist-keep-your-garage-door-working-smoothly-this-winter/) to replace remote batteries that have not been changed in a year, and that the outside keypad needs attention more often because the weather gets at it. Put a new battery in the keypad and check that your code still works. If a remote seems weak after that, our guide to [a remote that is not working](/blog/garage-door-opener-remote-not-working) goes through the rest. ## 4. Bulbs Change any burned-out opener bulbs now. Raynor notes that some LED bulbs can interfere with the remote, so if the remote gets worse after a swap, the bulb is the first thing to suspect. ## 5. The sensors Wipe both sensor lenses, check that nothing is blocking either one, and look at the light on each: steady means they are lined up. Then run the reversal test your opener's manual describes. If the door does not reverse, stop using the opener and call a technician. Never raise the force setting to make it pass. ## 6. If you have battery backup Winter storms are when it earns its keep. [Clopay mentions that many modern openers offer it](https://www.clopaydoor.com/blog/post/blog/2025/12/01/insulated-garage-doors-for-cold-climates), and our guide to [battery backup for garage door openers](/blog/garage-door-opener-battery-backup) explains how it works and what to ask about. ## What to leave to a technician Call a pro for anything on the spring, the cables or the brackets at the bottom corners, and for the opener's force settings. If the door reverses partway down on cold mornings, [do not turn the force up](/blog/garage-door-wont-close-night). Something is stiff or binding, and a technician finds out what. ## If the door freezes shut [Raynor](https://raynor.com/checklist-keep-your-garage-door-working-smoothly-this-winter/) says to clear snow and ice with a flat shovel or spade, avoiding the door finish. If it is still stuck, soften the ice with a hair dryer, and keep the heat away from the door and weather strip. Raynor also says not to cycle your automatic opener to break the ice, because it is not built to lift against a solid freeze. If the door will not come free, call a technician rather than forcing it. ## Wet door, no leak If the door is dripping or frosted but nothing is broken, that is usually condensation, and [we explain why and what helps](/blog/garage-door-condensation-in-winter). ## This weekend 1. Walk the bottom seal and look for cracks and gaps. 2. Spray the hinges and rollers with silicone. 3. Replace the keypad and remote batteries. 4. Wipe the sensor lenses and check both lights. 5. Call a technician about anything that touches the spring, the cables or the force settings.
