The One Rule, and When It Doesn't Apply
If your garage door hasn't had any attention since before the summer heat broke, budget an afternoon this month to get it ready for rain. That's the rule of thumb for most homes in the San Jacinto Valley, where the door sits mostly untouched through a long dry stretch and then suddenly has to deal with moisture, wind-driven dust, and temperature swings all at once.
The exceptions: if you already had the door serviced within the last six months, or it's a newer installation with sealed bearings and fresh weatherstripping, you can likely get by with a lighter once-over instead of a full prep session. And if you're on a slab that drains poorly or backs up to open ground where dust collects fast, you may need to check things more than once this season, not just at the start of it.
Clear Out What the Dry Season Left Behind
Months of dry weather and the occasional wildfire smoke haze leave a fine layer of grit on tracks, rollers, and the bottom seal. That grit doesn't just sit there — once winter rain and condensation show up, dust turns into a gritty paste that grinds into bearings and accelerates wear.
- Wipe down the tracks with a dry cloth, then a damp one, before applying any lubricant.
- Vacuum or brush out the bottom bracket area and the threshold where leaves and dust collect.
- Clean the photo-eye sensor lenses near the floor — dust film here is a common cause of doors that reverse or won't close for no obvious reason.
Check the Weatherstripping and Bottom Seal
The rubber seal along the bottom of the door and the flexible stripping along the sides are what keep wind-driven rain from pooling inside the garage. After a long dry summer, these parts often get brittle, cracked, or pulled away from the track.
- Press a thumbnail into the bottom seal — if it feels stiff or cracks instead of flexing, it's past due for replacement.
- Look for daylight gaps along the sides of the door when it's closed; a flashlight test from inside the garage at dusk works well for this.
- Replacement seal material is inexpensive and a reasonable DIY job for most homeowners, generally in the range of what you'd pay for a basic hardware store tool.
Look for Rust-Prone Spots Before the Rain Starts
Garage doors in this area don't usually deal with road salt, but moisture that sits on bare metal hardware after a wet week can still start surface rust, especially on older hinges, end bearing plates, and spring coils that have lost their factory coating. Rust on a torsion spring is worth taking seriously — it weakens the metal and changes how the spring handles tension, which matters more than most people expect.
- Spot-check hinges, hardware, and the spring itself for orange discoloration or flaking.
- A light coat of garage door lubricant on hinges and rollers helps shed moisture, but don't use household oil or WD-40 as a long-term fix — it attracts dust rather than repelling it.
- If you find active rust on the spring or the cable near the drum, that's a job to hand off rather than wire-brush and hope.
Check Drainage Around the Slab
A lot of homes in this valley have a slight grade issue at the garage entrance that nobody notices until the first real rain sends water pooling at the threshold. Standing water at the base of the door accelerates rust on the bottom bracket and can seep under the door if the seal is already worn.
- After the first rain, check whether water pools against the door or drains away from it.
- If it pools, a simple solution is a threshold seal strip added to the slab side, separate from the door's own weatherstripping.
Don't Forget the Electrical Side
Openers mounted near an exterior wall or a garage with a gap under the door can pick up more humidity in winter than people expect, even inland. Flickering opener lights, a remote that works inconsistently, or a wall button that feels unresponsive after a rainy stretch are worth checking before they turn into a dead opener on a Saturday morning.
- Make sure the opener's power cord and outlet aren't exposed to dripping water from a roofline or gutter gap.
- Test the manual release handle now, while the weather's dry, so you're not learning how it works during a storm-related power outage.
A Note on Older Homes and Bracing Hardware
Many houses in this area have had some form of structural retrofit work done over the years, and garage doors are often part of that conversation because the opening is a weak point in the wall. If your door's bracing hardware, strut reinforcement, or track anchors look like they haven't been touched since the house was built, winter — before any seismic activity or a heavy wind event — is a sensible time to have them checked alongside the rest of this list.
When to Call Hemet Garage Door
If you've gone through this list and found cracked seals you can't get flush, rust on the spring itself, or an opener that's acting up after damp mornings, that's where it makes sense to call in help rather than keep troubleshooting. Our Garage Door Maintenance visits cover the full tune-up — track cleaning, hardware inspection, lubrication, and seal checks — in one trip, and if a spring shows real wear, our Spring Replacement service handles it safely with the right tools, since a torsion spring under tension is not a DIY repair.
If you're anywhere in Hemet, San Jacinto, Menifee, Murrieta, Temecula, Winchester, Sun City, or Valle Vista and want your garage door squared away before the rain settles in, give Hemet Garage Door a call and we'll get it done right the first time.
