What We Find on the First Rainy-Day Service Call
Every year it's the same pattern. A homeowner calls because their garage door suddenly started grinding, sticking halfway up, or reversing on its own — and it's always right after the first real rain of the season. When we get there, the problem usually isn't the rain itself. It's months of dry-season dust and wildfire ash that built up quietly on the tracks, rollers, and springs all summer, and the first bit of moisture turned that dust into grit and grime. That grit works its way into bearings and hinges, and a door that ran fine in August suddenly sounds like it's dragging gravel in November.
The good news is that almost everything we find on these calls is preventable with an hour of attention before the rain really sets in. Here's what actually matters this time of year.
Clear Out the Summer Dust Before It Turns to Mud
Dry Santa Ana conditions and wildfire smoke leave a fine film on everything, including garage door hardware most people never think to clean. Before the rainy season takes hold:
- Wipe down the tracks with a dry cloth, then a damp one, to remove caked dust — don't just hose them off, since that can push grit deeper into the roller grooves.
- Check rollers and hinges for a gritty coating. If they look dull or chalky, clean them before lubricating, otherwise you're just sealing dust in.
- Use a garage-door-specific lubricant (not WD-40, which attracts more dust) on hinges, rollers, and the torsion spring.
This single step prevents most of the grinding and sticking calls we get once the rain starts.
Inspect and Replace Weatherstripping
The rubber seal along the bottom of the door and the vinyl stops along the sides and top are your first defense against winter rain getting into the garage. After a long dry summer, this rubber is often cracked, stiff, or pulling away from the track — and it's easy to miss because it looks fine until water is actually running underneath it.
- Press on the bottom seal. If it's hard or brittle instead of slightly flexible, it needs replacing.
- Look for daylight gaps along the sides when the door is closed.
- Replacement seal kits are inexpensive and usually a straightforward swap, but a door that's out of square may need adjustment first or the new seal won't sit right.
Keeping water out matters more than it sounds like in a garage that stores tools, a water heater, or anything on the floor that doesn't do well wet.
Check Springs and Hardware for Temperature Swings
Garage doors in this area deal with a wide swing between hot, dry days and cooler, damp winter mornings, and torsion springs respond to that. Metal contracts in cooler temperatures, which can make a spring that was already near the end of its life finally let go. If you notice the door feels heavier than usual when lifting it manually, or the opener strains more than it did a few months ago, that's a spring telling you it's losing tension.
Also take a minute to check all the exposed hardware — hinges, brackets, the track mounting bolts — for rust starting to form. Garages near the coast see this faster because of salt air, but even inland homes get surface rust once winter humidity sets in. A little surface rust is cosmetic; rust that's loosening a bracket or pitting a spring coil is not something to leave alone.
Test the Opener and Safety Sensors
Rain and higher humidity are hard on anything electrical, and garage door openers are no exception. Before winter:
- Test the auto-reverse safety feature by placing a block of wood or a roll of paper towels in the door's path and closing it — it should reverse on contact.
- Check the photo-eye sensors near the bottom of the tracks. These are low to the ground and can get splashed with mud or blocked by debris once the rain starts, which causes the door to refuse to close or reverse for no obvious reason.
- If your opener remote or keypad has been acting up intermittently, get it looked at now rather than during a storm when you actually need the door to work.
Give the Bracing a Look, Especially After Any Retrofit Work
If your home has had earthquake retrofit work done, it's worth checking that any added bracing around the garage opening hasn't shifted or doesn't interfere with the door's track alignment. Retrofit bracing is usually installed with the door's clearance in mind, but settling, minor seismic activity, or even just age can nudge things slightly out of position. A door that no longer closes perfectly flush, or that rubs against new bracing on one side, is worth addressing before it wears unevenly all winter.
When to Call Los Angeles Garage Door Service
If you've gone through this checklist and the door still sticks, grinds, reverses on its own, or feels noticeably heavier than it should, that's your cue to stop troubleshooting and call us. Our Garage Door Maintenance service covers a full inspection of tracks, rollers, springs, and hardware, so we catch the kind of wear that turns into a stuck door the first rainy week of the season. If a spring has lost tension or shows visible wear, our Spring Replacement service handles that safely — this is not a DIY repair, since a torsion spring under tension can cause serious injury if it's handled without the right tools and experience.
We work throughout Los Angeles, Glendale, Pasadena, Burbank, Eagle Rock, Highland Park, Glassell Park, and Silver Lake, and we'd rather do a quick maintenance visit now than an emergency repair during the first big storm. Call Los Angeles Garage Door Service today to get your door ready before the rain settles in.
