Here's what most homeowners don't realize about garage door repair: half the time, your door isn't actually broken. It's stuck, misaligned, or simply needs lubrication. But knowing the difference between a quick fix and a job that requires professional hands is where most Redwood City homeowners get stuck. This guide walks you through real troubleshooting steps so you can decide whether to grab your wrench or call in the experts.
A garage door that won't open can stem from several places. Start with the simplest culprit: the remote batteries. Replace them first. If the wall button works but the remote doesn't, you've just saved yourself a service call.
Next, check the photo eye sensors near the bottom of your door track. These small sensors prevent the door from closing on objects or people. If one is blocked by dust, a spider web, or misaligned, your door won't budge. Clean the lenses gently with a soft cloth. Wipe both sensors and make sure they're facing each other squarely.
If the door still won't open, listen for the opener motor running. If you hear it humming but the door doesn't move, your springs may be the issue. Springs do the heavy lifting. When they break or weaken, the motor can't overcome the door's weight. Springs last roughly 7 to 9 years depending on use and climate. The salty Redwood City air and coastal moisture can accelerate wear. This is not a DIY fix. Garage door springs are under extreme tension and can cause serious injury. Call a professional immediately.
Sometimes your door opens, but it moves sluggishly or sounds like it's grinding. This usually points to lubrication or track alignment issues.
Walk the length of your door track on both sides. Look for bends, dents, or buildup of dirt and leaves. A crooked track forces the rollers to work harder. Use a level to check if your track runs true. Minor obstructions can be cleared with a brush or vacuum. Bent metal requires professional straightening.
Next, apply garage door lubricant to the tracks, hinges, and roller stems. Use a silicone-based spray, not WD-40 or heavy oil. Silicone won't attract dirt. Let the lubricant sit for a few minutes, then operate the door several times. Many stuck doors come back to life after proper lubrication.

Why is my garage door making noise? Noise usually comes from dry hinges, worn rollers, or misaligned tracks. Lubrication and minor adjustments fix most squeaks and grinding sounds. See our guide to noisy garage doors for detailed troubleshooting.
When should I replace my garage door instead of repairing it? If your door is over 15 years old and repairs exceed 50% of a replacement cost, replacement often makes financial sense. We can help you evaluate whether repair or replacement is the right call for your situation.
