September is the best month to winterize your garage door in Northern Colorado. A local pro's fall checklist: springs, seals, sensors, and lubrication.
The first hard freeze hits Fort Collins sooner than you think. Here's the fall checklist we run on our own doors — seals, springs, sensors, and the lube that actually works below zero.
If you live anywhere from Fort Collins to Loveland to Greeley, you know how fast fall turns to winter up here. One week it's 75°F and sunny, the next week there's ice on the windshield and your garage door is groaning like it aged ten years overnight. September and early October are the sweet spot — warm enough to work outside, early enough to beat the rush when everyone's door fails on the first 20°F morning.
Start with the weather seals. The bottom seal is the single cheapest upgrade you can make, and it's the first thing to fail. If yours is cracked, brittle, flattened, or chewed up, cold air, snowmelt, and mice will find their way in all winter. Check the perimeter seals along the sides and top too — stand inside with the door closed on a sunny day and look for daylight. Anywhere light gets in, so does a January wind off the plains.
Lubricate before it gets cold — and use the right stuff. Cold thickens cheap grease and turns a smooth door into a loud, straining one. Hit the springs, hinges, roller bearings, and the opener's chain or screw drive with a silicone or lithium-based spray rated for low temperatures. Never use WD-40 — it's a degreaser, not a lubricant, and it will strip the protection your parts need heading into freeze-thaw season. Wipe the tracks clean but leave them dry.
