How Selma's Wet Season Punishes Garage Doors: and What to Do About It
2026-04-08 7 min read
If you've lived in Selma or anywhere in the Illinois Valley for more than a year, you already know what October through March looks like: gray skies, saturated ground, and rain that just keeps coming. Selma averages over 42 inches of rain annually. more than the national average. and while that keeps the Illinois River running clear and the hills green, it's genuinely hard on garage doors. Wood swells, metal rusts, weatherstripping rots, and tracks fill with grit. Most homeowners don't think about their garage door until something stops working. By then, the damage is usually worse. and more expensive. than it needed to be.
Here's a practical, honest guide to getting your garage door ready for the wet months before they arrive.
Why the Illinois Valley's Rain Is Especially Tough on Garage Doors
Selma sits in a valley carved by the Illinois River, surrounded by the Siskiyou National Forest. That geography creates a funnel effect during storm systems. moisture rolls in off the Pacific, gets pushed into the valley, and doesn't have anywhere easy to go. Homes along Clear Creek and Deer Creek have particularly high flood risk, but even properties on higher ground deal with persistent ground saturation, pooling water, and humidity that lingers for days between storms.
The combination of heavy rain, occasional freezing temperatures in December and January, and high humidity throughout fall and spring creates a specific kind of stress on garage door systems. Metal hardware corrodes faster. Wood door panels absorb moisture and warp. Weatherstripping at the bottom of the door. that rubber or vinyl seal that keeps water from flowing into your garage. takes a beating every time it sits in a puddle.
Out in Cave Junction and Murphy, neighbors deal with the same patterns. Anyone with a garage door along Route 199 knows that the wet season isn't a short event. it's a five-month reality.
Start With the Bottom Seal
The bottom weatherstrip is your first line of defense against rain intrusion. If yours is cracked, flattened, or missing chunks, water will work its way under the door and pool on your garage floor. Over time, that moisture damages stored items, contributes to mold, and can warp a wood floor if your garage is finished.
Inspect the bottom seal before the rains start. Close the door and look for daylight coming under it. if you can see light gaps, water will get in too. Replacing a worn bottom seal is one of the cheapest maintenance tasks you can do, usually under $30 for the material if you do it yourself. A technician can handle it quickly as part of a broader service call.
Also check the side and top weatherstripping. the seals that run along the door frame. These are often overlooked but play a real role in keeping wind-driven rain from getting in around the edges.
Lubrication: More Important in Wet Weather
Moisture is the enemy of metal hardware. Hinges, rollers, springs, and the torsion bar above the door are all exposed to humidity, and in Selma's wet season, that exposure is constant. Springs in particular are at risk. they're under tension, they flex thousands of times over their lifespan, and if surface rust takes hold, they become brittle and more prone to snapping.
Before the wet season sets in, lubricate all moving metal parts with a silicone-based or lithium-based lubricant. Avoid WD-40 for this. it's a solvent, not a long-term lubricant, and it evaporates quickly. Work the lubricant into:
- Hinges along each panel - Rollers (focus on the ball-bearing stem, not the nylon wheel itself) - Springs. a light coat on the coils, not soaked - The torsion bar and end bearing plates - Tracks. but only lightly; excess lubricant in the track attracts debris
If your springs are already showing significant rust or corrosion, don't just lubricate over the problem. Check out our complete guide to spring replacement to understand when a spring needs to be replaced rather than maintained.
Inspect the Door Panels for Moisture Damage
If you have a wood garage door. common on the custom homes, Craftsman-style builds, and older properties throughout the Selma area. pay close attention to the panel surfaces. Wood absorbs moisture, and after several wet seasons, panels can warp, crack, or delaminate at the seams. This isn't just a cosmetic issue. A warped panel creates gaps that let water in and compromises the structural integrity of the door.
Steel and aluminum doors are less susceptible, but they're not immune. Look for rust at the bottom of steel panels, especially if the factory paint or coating has chipped. Once bare metal is exposed, rust spreads quickly in a humid climate. Touch up chipped areas with an exterior metal primer before the rains start.
Check the Tracks and Drainage Around the Garage
Tracks can collect leaves, pine needles, dirt, and other debris that gets washed in during heavy rain events. A clogged or bent track causes the door to bind, move unevenly, or come off the rollers entirely. Walk the tracks from top to bottom and clear out any buildup. Look for sections that have pulled away from the wall or bent inward. track alignment issues tend to get worse during winter when temperature swings (Selma's lows can dip to the low 30s in December and January) cause the metal to contract slightly.
Also look at what's happening around the garage floor. If water consistently drains toward your garage door rather than away from it, you may need to address grading or install a simple threshold seal that creates a raised dam at the door's base. This is a common fix on older properties where the driveway has settled over time.
Don't Skip the Opener
Your opener lives in the garage and breathes the same damp air your door hardware does. High humidity can affect circuit boards, cause corrosion on terminal connections, and degrade the drive system. whether you have a chain, belt, or screw drive. If your opener is more than 10,12 years old and you haven't had it serviced, consider having a technician look at it before winter. You don't want to find out it's failing on a cold, rainy morning when you're trying to get to work.

A Simple Pre-Season Checklist
Here's a quick rundown you can do yourself in about 20 minutes:
1. Inspect bottom weatherstripping. replace if cracked or compressed flat 2. Check side and top weatherstripping for gaps 3. Lubricate all metal moving parts with silicone or lithium spray 4. Inspect panel surfaces for rust, warping, or delamination 5. Clear debris from tracks, check for bends or gaps from the wall 6. Test auto-reverse safety features. place a 2x4 flat on the ground under the door and close it; it should reverse on contact 7. Observe where water drains around your garage. redirect if needed 8. Test your opener's manual release cord for smooth operation
If anything on that list looks questionable, it's worth a call before the rainy season hits full stride. Small problems caught in September or October are almost always cheaper and easier to fix than the same problems discovered in January.

Frequently Asked Questions
Q: How often should I lubricate my garage door hardware in Selma's wet climate? A: At minimum, once before the wet season begins (September,October) and once in spring after it ends. If you notice squeaking or stiffness during winter, lubricate again mid-season. The persistent humidity here means metal hardware needs more attention than in drier climates.
Q: My garage door bottom seal looks okay but water still gets in. What's the problem? A: The issue may be with side or top weatherstripping, or it could be that water is pooling and coming in under the threshold rather than through the seal. Check the grading around your garage entry. water should slope away from the door, not toward it. A threshold seal (a raised rubber dam that mounts to the floor) can also help if the drainage problem isn't easy to fix.
Q: Is it normal for my garage door to feel stiff or slow during cold, wet weather? A: Some stiffness is common as temperatures drop into the low 30s, especially if hardware hasn't been lubricated recently. However, significant resistance, grinding sounds, or a door that only moves partway usually signals something beyond normal seasonal behavior. a spring issue, track problem, or opener strain. Those are worth having a professional look at rather than forcing the door repeatedly.
