Why Union Homeowners Need to Weatherproof Their Garage Doors Every Fall
2026-03-20 7 min read
Living along Hood Canal in Union, WA means you get some of the most dramatic Pacific Northwest weather imaginable. The canal acts like a funnel for moisture-laden air rolling in off the Olympic Peninsula, and the numbers back that up. Union sees roughly 185 rainy days per year and accumulates over 42 inches of precipitation annually, with January alone dumping more than 7 inches of rain. November and December push relative humidity to around 90%. If you own a home in the Alderbrook community, along Lynch Cove, or anywhere near the waterfront, your garage door is essentially fighting a year-round battle against moisture, wind gusts, and temperature swings.
Neighbors over in Olympia and Tumwater deal with wet weather too, but Union's position right on the canal tends to intensify things. That means the standard Pacific Northwest garage door advice. "lubricate it once a year". genuinely isn't enough here.
Why Union's Climate Is Hard on Garage Doors
The combination of persistent rain, high humidity, and near-freezing winter temperatures creates several specific problems for garage doors in this area.
Wood Doors and Moisture Swelling
Many of the older cottages and established homes around Alderbrook Golf & Yacht Club were built with traditional wood garage doors that carry real curb appeal. The problem is that wood absorbs moisture aggressively. During prolonged wet weather, wooden garage doors and door frames can absorb moisture and swell, which directly affects how the door operates. sometimes causing it to stick or bind against the frame entirely. If you have a wood door and notice it dragging or requiring extra force to close after a rainy stretch, swelling is almost certainly the culprit.
The fix isn't complicated, but it does need to happen on schedule. Sand any areas where the door is rubbing, apply a quality exterior sealant or paint rated for high-moisture environments, and check the condition of your weatherstripping at the same time.

Seal Failures and Water Intrusion
The bottom seal on your garage door is the first line of defense against rain sheeting across your driveway and pooling inside the garage. Cracked or brittle bottom seals allow cold air to rush in at the base of the door and keep the steel panels at a lower temperature, which worsens condensation problems on top of water intrusion. Silicone-based gaskets with enhanced flexibility tend to perform better in variable climates like Union's because they maintain their shape through temperature swings rather than stiffening in the cold.
Inspect your bottom seal every fall before the heavy rains arrive. It should lie flat against the floor with no visible cracks or gaps. A replacement bottom seal is an inexpensive part, and swapping one out is one of the few garage door jobs a careful homeowner can handle without a technician.
Rust and Corrosion on Metal Hardware
With humidity sitting near 90% for months at a time, unprotected metal components. springs, hinges, rollers, and tracks. are constantly under threat. High moisture levels cause rusting of metal parts, which weakens them and can lead to squeaking, slow operation, or outright failure. Springs are particularly vulnerable; a rusty spring is more brittle and far more likely to snap under tension without warning.
Lubricating your hardware with a silicone-based or lithium-grease spray once in early fall and again in late winter goes a long way. Avoid WD-40 for this task. it's a solvent, not a lubricant, and it evaporates quickly in damp conditions. Wipe down the tracks first to remove grit and debris, then apply lubricant sparingly to rollers, hinges, and the spring coils.
Your Fall Weatherproofing Checklist
Here's a practical, step-by-step checklist Union homeowners should work through before November:
- Inspect the bottom seal. Replace if cracked, torn, or no longer lying flush with the floor - Check side and top weatherstripping. Look for gaps, tears, or sections that have pulled away from the door frame - Lubricate all moving metal parts. Springs, rollers, hinges, and tracks with a silicone or lithium spray - Clear the gutters above the garage. Water overflowing from clogged gutters splashes directly onto the door and pooling water near the door threshold is a primary cause of freezing problems in January and February - Test door balance. Disconnect the opener and lift the door manually to the halfway point. It should stay put. If it falls or rises on its own, the springs need attention - Inspect wood doors for surface damage. Touch up any bare wood with exterior-grade paint or sealant before the rains lock in

What About Wind?
Union and the Hood Canal corridor can see south winds with gusts topping 40 mph during fall and winter storm systems. Strong winds can cause debris to dent panels or knock your door off its track. and that's not a minor inconvenience when it happens in the middle of a storm. If your door panels already have dents or soft spots, they're less rigid and more vulnerable to the next hit. It's worth having those assessed before storm season begins. If you've already got damage, reach out to schedule a repair before the worst weather arrives.
Don't Wait Until Something Breaks
The honest reality is that most garage door failures in Union happen in the coldest, wettest part of the year. precisely when you least want to deal with them. A door that freezes open at 6 AM on a January morning is an emergency. A door that gets a tune-up in September is a non-issue.
Garage Door Union serves homeowners throughout Union and the surrounding Mason County area. A seasonal inspection takes less than an hour and can catch the issues that the climate here quietly builds up all year long. Taking care of it in fall beats a cold-weather emergency call every time.
Frequently Asked Questions
How often should I lubricate my garage door in Union's climate?
Given the high humidity and rainfall in Union, lubricating your door's moving parts. springs, rollers, hinges, and tracks. twice a year is recommended: once in early fall before the wet season and once in late winter. Use a silicone-based or lithium-grease spray, not WD-40.
Why does my garage door stick after it rains?
If you have a wood door, the most likely cause is moisture swelling. Wood absorbs rainwater and expands, reducing the clearance between the door and the frame. Applying a quality exterior sealant and keeping up with repainting helps prevent this. If you have a steel door, the issue is more likely a warped or misaligned track. worth having a technician check.
Is it normal to see water pooling inside my garage after heavy rain?
Not normal, and worth addressing promptly. It's most often caused by a failed bottom seal, clogged gutters overflowing onto the driveway, or a gap in the side weatherstripping. In some cases it can also be condensation "sweating" off uninsulated steel panels during temperature shifts. a common issue in the Pacific Northwest's winter months.
