When the winter rain starts hitting Burnaby, we all know the drill. The air gets heavy, the temperatures drop, and everything starts to feel a bit more sluggish. While we’re busy grabbing our umbrellas and turning up the heat, our commercial overhead doors are taking a serious beating.
Between the humidity and the occasional cold snap, the moving parts of your bay doors are under constant stress. At Knock Knock Repair, we see a huge spike in calls for overhead door repair in Burnaby as soon as the weather turns.
In the summer, a little friction might not seem like a big deal. But when it’s cold, metal contracts and old grease thickens up. If your door is making a grinding or screeching sound, it’s crying for help. A quiet door is a happy door. If it sounds like a freight train, it’s probably time to look into a professional overhead door repair in Burnaby before a part actually snaps.
The rubber seal at the bottom of your door has a tough job. It keeps the rain, wind, and local rodents out of your warehouse. Over time, these seals crack or flatten out. If you can see daylight under your door when it’s closed, you’re losing heat and inviting water damage. Replacing a brittle seal is a cheap way to save on energy bills and keep your floor dry.
Don’t just grab any old can of grease! Standard grease can actually get “gummy” in the cold and attract dirt. We always recommend using a high-quality silicone or lithium-based spray. Focus on the rollers, hinges, and tracks. This keeps everything sliding easily and reduces the strain on your motor, which is the most expensive part to replace.
This is a big one for safety. If you disconnect your opener and try to lift the door halfway by hand, it should stay put. If it slams shut or shoots upward, your springs are out of whack. In Burnaby’s damp climate, springs can develop surface rust which makes them brittle. Please be careful here – springs are under a massive amount of tension. If the balance is off, that’s a job for the pros.
Winter in Burnaby means wind, which means leaves and debris blowing into your tracks. If your door starts to close and then suddenly reverses for no reason, check your photo-eye sensors at the bottom. A quick wipe with a soft cloth to remove dirt or spiderwebs often does the trick and saves you a service call.
