How Clackamas's Wet Winters Are Slowly Damaging Your Garage Door (And What to Do About It)
2026-03-19 7 min read
If you've lived in Clackamas for more than one winter, you already know what November through March feels like. grey skies, persistent drizzle, and the kind of damp that seeps into everything. What most homeowners don't realize is that same moisture is quietly working against their garage door every single day. Whether you're in one of the newer subdivisions off Sunnyside Road or in an older ranch-style home closer to Oregon City, your garage door takes a beating during the wet season that you simply won't find in drier parts of the country.
Clackamas County averages over 53 inches of rain per year. well above the U.S. average of 38 inches. and December alone can dump nearly 8 inches of precipitation on the area. That's not a brief rainy season. It's half the calendar year of sustained moisture exposure for every metal hinge, rubber seal, and wood panel on your garage door.
What the Rain Actually Does to Your Garage Door
Rust on Metal Components
The most common and costly problem we see here in Clackamas is rust. Metal springs, hinges, rollers, and tracks are all vulnerable. The Pacific Northwest's persistent rain and high humidity keep metal surfaces wet for extended periods, giving rust a foothold that spreads beneath the surface coating before you ever notice it on the outside. By the time you see rust, the corrosion has usually been developing for months.
A quick visual check each fall. before the wet season really kicks in. can catch this early. Look for orange-brown discoloration on hinges and the white powdery residue around bolt heads that signals active oxidation.

Weatherstripping That Cracks and Gaps
The rubber seals along the bottom and sides of your door expand and contract with every temperature swing. In Clackamas, those swings happen constantly. cold, wet winters followed by summers that can push into the mid-80s. Over a few years, that repeated cycling causes the rubber to crack, harden, and pull away from the door frame.
A failed bottom seal doesn't just let in water. It also invites cold air, pests, and leaves from the Douglas firs and Oregon white oaks that are common in Clackamas-area yards. Test your bottom seal by closing the door and looking for daylight underneath. On a rainy day, you can place a piece of cardboard on the floor just inside the door. if it gets wet, your seal has failed.
Wood and Composite Panel Warping
Many of Clackamas's older homes. particularly the mid-century ranches and bungalows that make up a good portion of the housing stock closer to the Portland border. were fitted with wood or wood-composite garage doors that simply weren't designed with the Pacific Northwest in mind. As these panels absorb moisture during our long rainy seasons, they swell. When the dry summer arrives, they contract again. but rarely back to their original shape. After several wet-dry cycles, warping creates gaps between panels where weather seals should meet, letting rain and wind directly into your garage.

A Practical Clackamas Maintenance Routine
You don't need to spend a lot of money or a full weekend to stay ahead of moisture damage. Here's a straightforward seasonal approach:
Every September (Before the Rain Arrives)
- Inspect and replace weatherstripping along the top, sides, and bottom of the door. This is the single most effective moisture barrier you have. - Lubricate all metal components. hinges, rollers, and the chain or belt drive on your opener. using a white lithium grease or silicone-based product. Avoid WD-40 on these parts; it's a degreaser, not a long-term lubricant, and it washes off quickly in wet weather. - Check your rain gutters above the garage door. Clogged gutters overflow directly onto the door, accelerating moisture damage at the top panel and frame. - For steel doors, apply a protective wax to the panels. This creates a hydrophobic layer that causes water to bead and roll off rather than soaking into microscopic surface imperfections.
Every Spring (After Winter's Damage)
- Walk the door and look for rust spots, paint bubbling, or cracks in panels. Catching corrosion at this stage. rather than next fall. is the difference between a $20 touch-up and a full panel replacement. - Test door balance by disconnecting the opener and manually lifting the door halfway. It should stay put without your help. If it drops or rises on its own, your springs need attention. - Clean the tracks with a dry cloth and inspect for debris that accumulated over winter.

When to Call a Professional
DIY maintenance goes a long way, but there are a few situations where you should call in a pro rather than guess. Visible rust on the springs, a door that won't stay balanced, panels that have warped enough to let in light along the edges, or broken seals on the spring assembly. these aren't weekend projects. Springs in particular are under significant tension and can cause serious injury if handled incorrectly.

Frequently Asked Questions
Q: How often should I lubricate my garage door in a climate like Clackamas? A: At minimum, twice a year. once in September before the wet season and once in April after winter. If you notice grinding or squeaking at any other time, don't wait for the schedule. Apply white lithium grease or a silicone-based lubricant to hinges, rollers, and the drive mechanism.
Q: My garage door panels are showing rust spots. Do I need a full replacement? A: Not necessarily. Surface rust caught early can be sanded, primed, and touched up with exterior latex paint. If the rust has perforated the panel or spread to multiple areas, replacement makes more financial sense. A professional inspection will give you a clear answer.
Q: Is weatherstripping replacement something I can do myself? A: Yes, for most homeowners. Bottom seals and side weatherstripping are available at hardware stores and install with basic tools. If you're unsure what size or type fits your door, take a photo of the existing seal and bring it in. or check our FAQ page for guidance on common door and seal types.
