Getting a garage door ready for winter on the Eastside means dealing with water first and cold second. Start by replacing worn weatherstripping, clearing drainage paths so rain doesn't pool at the threshold, checking wood trim for rot or moss, and lubricating hinges and rollers while temperatures are still mild. Do this in October or early November, before the heavy rain settles in for the season.
Start With the Weather Seal, Not the Spring
The bottom seal and side weatherstripping are the first line of defense against the rain that defines a Pacific Northwest winter. Walk outside and look at the rubber gasket along the bottom of the door. If it's cracked, flattened, or pulling away from the track, it's not doing its job. Water will find that gap, and so will cold air and the occasional spider or rodent looking for shelter.
Side and top seals matter too, especially if your garage shares a wall with living space. Replacement seals are inexpensive and most hardware stores carry standard sizes, but getting the fit right on an older track profile can be fiddly. If the door is more than a few years old, it's worth having someone check whether the track still accepts a standard seal before you buy one that doesn't fit.
Clear the Water Path Before the Rain Doesn't Stop
A lot of winter garage door problems start outside the door itself. Check that the concrete apron slopes away from the garage and isn't holding standing water against the threshold. Clear leaves and debris from any nearby drains or gutters, and make sure downspouts aren't dumping water directly onto the driveway in front of the door. On the Eastside, a clogged gutter during a heavy autumn rain can send a sheet of water right at the base of the door, which accelerates rot on wood trim and can seep under a worn seal no matter how new it is.
If your garage sits at the bottom of a slope or driveway, this is also the time to notice whether water tends to collect near the opening during a storm. A small drainage fix now, like redirecting a downspout or adding a bit of gravel, is easier than dealing with a swollen door panel in January.
Protect Wood Trim and Jambs From Rot and Moss
Wood jambs, trim, and door panels take a beating during months of damp weather. Look closely at the corners and bottom edges of any wood trim around the opening for soft spots, dark staining, or moss growth. Moss holds moisture against the wood and accelerates rot, so scrape it off and let the area dry out before winter humidity locks it in for good.
If you catch soft or discolored wood now, a coat of exterior sealant or paint can buy time, but once wood has gone spongy, patching won't hold through a wet winter. Replacing a rotted section of trim in October is a much smaller job than replacing it in February after it's spread.
Lubricate While It's Still Mild
Cold, damp air thickens old grease and grime on hinges, rollers, and the torsion spring, which makes the door work harder and age faster. A light silicone or lithium-based garage door lubricant on the hinges, rollers, and track (not the seals, which don't need it) keeps things moving smoothly once temperatures drop. Mild fall days are the easiest time to do this, since you're not fighting ice or standing in a downpour to reach the track.
Quick Safety and Function Checklist
- Test the auto-reverse by placing a block of wood in the door's path and closing it.
- Check that photo-eye sensors near the floor are clean and properly aligned.
- Confirm the opener's battery backup still holds a charge in case of a winter power outage.
- Pull the manual release cord to make sure it still works smoothly in an emergency.
- Listen for grinding or straining sounds during a full open-and-close cycle.
When to Call Sammamish Door & Opener
If you find a seal that won't seat right, a panel that's starting to sag or warp, or an opener that struggles more than it used to, that's the point to bring in a professional rather than patch it yourself. Our Garage Door Maintenance service covers a full inspection of hardware, seals, and opener function in one visit, and our Garage Door Opener Service can diagnose a battery backup or sensor issue before it leaves you stuck outside during a storm. Catching these things in October is a lot more pleasant than troubleshooting them during an ice storm in January.
