Garage doors are among the most frequently used components of a home, opening and closing multiple times a day. They offer convenience, security, and protection for vehicles and other belongings. However, due to their constant use and mechanical complexity, garage doors are also prone to wear, damage, and malfunction over time.
Understanding how garage doors work, recognising signs of trouble, and knowing when to seek professional help can help homeowners avoid costly repairs and potential safety risks. In this article, we’ll break down everything you need to know about garage door repair.
How Garage Doors Work
Before diving into repairs, it’s helpful to understand how a garage door operates. A typical garage door system consists of several key components:
- Panels: The sections of the garage door that form the actual barrier.
- Tracks and Rollers: These guide the door up and down during operation.
- Springs: Either torsion or extension springs, which counterbalance the door’s weight.
- Cables: Work with the springs to safely lift and lower the door.
- Hinges and Hardware: Connect the panels and allow flexibility in movement.
- Garage Door Opener: The motorised device that automates the opening and closing process.
- Safety Sensors: Infrared sensors that prevent the door from closing when an object is detected.
These parts work in unison, and failure in even one component can affect the entire system.
Common Garage Door Problems
Garage doors are durable but not indestructible. Here are some of the most common issues homeowners face:
1. Broken Springs
Garage door springs bear the most stress. They support the heavy lifting of the door and are designed for a limited number of cycles (one cycle = one opening and one closing). When a spring breaks, the door may not open, or it may come crashing down. Replacing a broken spring is a job for professionals due to the extreme tension involved.
2. Worn or Frayed Cables
Cables work with the springs to raise and lower the door. Over time, they can become frayed or break entirely, especially if the springs are not functioning correctly. A snapped cable can make the door unbalanced or cause it to jam.
3. Misaligned or Bent Tracks
The door tracks must be straight and properly aligned. If a track becomes bent or misaligned, it can prevent the door from moving smoothly. This might lead to loud grinding noises or a completely stuck door.
4. Opener Malfunctions
Garage door openers can experience various issues, including motor failure, faulty circuit boards, or worn-out gears. Remote control and keypad problems are also common, usually due to battery issues or signal interference.
5. Sensor Misalignment
Safety sensors are located near the base of the door tracks. If they become dirty or misaligned, the door may not close properly or may reverse unexpectedly. Cleaning and realigning the sensors often resolves the issue.
6. Noisy Operation
If your garage door makes unusual noises during operation—such as squeaking, grinding, or rattling—it may be due to worn rollers, loose hardware, or insufficient lubrication.
DIY vs. Professional Repair
Some garage door maintenance tasks can be safely handled by homeowners:
- Lubricating moving parts (rollers, hinges, and springs)
- Cleaning the tracks and sensors
- Tightening loose screws and bolts
- Replacing remote control batteries
However, many repairs involve high-tension parts and can be extremely dangerous. You should always hire a professional for the following:
- Replacing torsion or extension springs
- Repairing or replacing cables
- Fixing garage door opener motors or electrical issues
- Realigning bent tracks
- Rebalancing the garage door
Attempting to perform these tasks without the proper tools or expertise can lead to serious injury or further damage.
Signs You Need Garage Door Repair
Early detection can prevent major breakdowns. Look out for the following warning signs:
- The door is slow to open or close
- Unusual noises during operation
The door doesn’t open or close all the way - The door is off its tracks or uneven
- The remote or keypad is not working properly
- The opener motor runs, but the door doesn’t move
- Visible damage to cables or springs
If you notice any of these issues, it’s best to call a certified technician for an inspection.
Preventive Maintenance Tips
Regular maintenance can extend the life of your garage door and reduce repair costs. Follow these simple tips:
- Lubricate springs, rollers, and hinges every 6–12 months
- Inspect hardware and tighten loose bolts
- Check cables and springs for wear
- Clean photo-eye sensors regularly
- Test the door’s balance and safety features monthly
- Replace weatherstripping to keep out moisture and pests
Preventive care can significantly improve your garage door’s performance and lifespan.
Choosing the Right Garage Door Repair Service
When hiring a garage door repair company, consider the following:
- Experience: Choose companies with years of experience and trained technicians.
- License and Insurance: Ensure they’re properly licensed and insured.
- Reviews and References: Check online reviews and ask for referrals.
- Warranty: Look for service providers who offer warranties on parts and labour.
- Transparent Pricing: Avoid companies that won’t provide upfront estimates.
Reliable professionals will inspect your door, clearly explain the problem, and provide cost-effective solutions.
Conclusion
Garage doors are essential to your home’s safety and convenience, but they require regular maintenance and occasional repairs. While minor issues can sometimes be handled with basic DIY skills, more complex problems should be left to professionals. Recognising early signs of trouble and scheduling timely repairs can save you from bigger expenses and ensure your garage door continues to function properly for years to come.
