The Hardest Working Door on Your Home
Your garage door is more than just an entryway; it's a massive, complex moving system that you rely on for security, convenience, and curb appeal. When it works, it's seamless. But when it breaks, it's not just an inconvenience—it can be a serious safety hazard. This guide will walk you through the essentials of garage door maintenance, common repairs, and how to make the smart choice between repairing or replacing.
Garage Door Maintenance Every Homeowner Should Do
The vast majority of garage door problems are preventable. A little proactive maintenance can add years to the life of your door and opener. Here are the simple checks you should perform:
- Lubricate Moving Parts: Once every few months, use a lithium-based garage door lubricant (not WD-40) on the hinges, rollers, and springs.
- Test the Safety Sensors: This is a critical monthly test. Place an object (like a roll of paper towels) in the path of the door. When you press the close button, the door should reverse upon detecting the object.
- Check for Loose Hardware: The vibration of the door can loosen bolts and brackets over time. Gently tighten any you find.
- Inspect the Bottom Seal: A worn-out, cracked weather seal lets in pests and drafts. It's a simple, replaceable part.

Common Problems (and When to Call a Pro)
Many issues, like a dead remote battery or a misaligned safety sensor, are simple DIY fixes. However, a garage door's springs and cables are under extreme tension and can be incredibly dangerous. For a full list of safe troubleshooting, see our guide to 10 Common Garage Door Problems (and How to Fix Them Safely).
CRITICAL SAFETY WARNING: Always call a professional for any issues related to broken springs or frayed cables. These components are under enough tension to cause serious injury or death. This is not a DIY job. Learn more at Why You Should Always Hire a Professional for Garage Door Spring Repair.

Repair vs. Replace: How to Make the Call
This is a common dilemma for homeowners with an older door. Use these factors to guide your decision:
The Age of the Door: If your door is 15-20+ years old and needs a major repair, the money is often better spent on a replacement.
- The Extent of the Damage: A single broken spring is a simple repair. Multiple rotted or damaged panels, however, usually signal that replacement is the more cost-effective option.
- Energy Efficiency: A new, insulated garage door can significantly reduce your heating and cooling bills if your garage is attached to your home.
- Curb Appeal & Resale Value: A new garage door is one of the top home improvements for ROI, often recouping over 90% of its cost at resale.
