- Torsion spring
- A tightly wound metal spring mounted above the garage door that counterbalances the door’s weight, making it easy to open and close. Unlike extension springs, torsion springs unwind slowly and safely, reducing the risk of sudden breakage that can cause serious injury. Burbank’s hot summers stress springs faster, so annual inspection is critical to prevent failure during peak use. See our full list of services.
- Extension spring
- A long spring that stretches along the garage door tracks, providing lift when the door opens. These springs are under extreme tension and can snap violently if they break, posing a major safety hazard. Older homes in Burbank often have extension springs; if yours does, consider upgrading to torsion springs for safer, quieter operation. Learn more at request a free estimate / contact us.
- Track
- The metal rails that guide your garage door as it moves up and down. Tracks must stay perfectly aligned to prevent the door from binding or coming off the rollers. Burbank’s uneven sidewalks and tree roots can knock tracks out of alignment over time, so periodic checks are essential for smooth operation.
- Roller
- The small wheels that ride inside the tracks, carrying the weight of the garage door as it opens and closes. Rollers can wear out or crack, causing the door to jam or derail. If you hear grinding noises from your Burbank garage, worn rollers are often the culprit—replace them before they damage the tracks.
- Opener
- The motorized unit that automates your garage door’s movement, controlled by a remote, keypad, or smartphone app. Modern openers include safety features like auto-reverse and rolling-code encryption to prevent break-ins. Burbank homeowners should choose a model with battery backup to keep working during power outages.
- Photo-eye sensor
- A pair of infrared beams mounted near the garage door’s bottom that detect obstructions and stop the door from closing. These sensors are required by California safety codes and prevent tragic accidents, especially in homes with kids or pets. Test them monthly by waving an object in the beam’s path.
- Limit switch
- A safety device inside the garage door opener that tells the motor when to stop opening or closing the door. If the limit switch is misadjusted, the door may not fully close, leaving your garage vulnerable to pests or intruders. Burbank’s hot, dry climate can cause plastic parts to warp, so check the switch annually.
- Weatherstripping
- The rubber or vinyl seal along the sides and bottom of your garage door that blocks drafts, dust, and pests. High-quality weatherstripping also prevents carbon monoxide from seeping into your home—a critical safety feature for attached garages in Burbank. Replace cracked or flattened strips to maintain energy efficiency and safety.
- R-value (insulation)
- A measure of how well your garage door’s insulation resists heat flow. Burbank’s scorching summers make a high R-value door essential for keeping your garage—and home—cooler. Look for doors with R-values of 10 or higher, or add reflective insulation panels to existing doors for better performance.
- Cable drum
- A grooved wheel attached to the torsion spring shaft that winds and unwinds the lift cables as the door opens and closes. If a cable drum is corroded or misaligned, it can cause the cables to jump off, leading to sudden door failure. Burbank’s humidity accelerates rust, so inspect drums during spring maintenance.
- Bottom seal
- The thick rubber strip at the bottom of your garage door that seals the gap between the door and the driveway. A worn bottom seal lets water, pests, and carbon monoxide enter your garage. Replace it every 2–3 years or if you notice daylight under the door when it’s closed.
- Travel module
- The electronic brain of your garage door opener that controls speed, force, and safety features. If your opener behaves erratically—like stopping mid-cycle—it may need a travel module adjustment or replacement. Burbank’s power surges can damage sensitive electronics, so consider a surge protector for your opener.
- Trolley
- The part of the garage door opener that connects the motor to the door, pulling it along the tracks. A worn or misaligned trolley can cause the door to jerk or stop unexpectedly. If your Burbank garage door opener is more than 10 years old, the trolley may be due for replacement to avoid sudden failure.
- Manual release
- A red handle or cord inside the garage that disconnects the door from the opener in case of power failure or emergency. Always test your manual release twice a year to ensure it works smoothly. Burbank’s frequent heatwaves can cause plastic components to become brittle, so check the release mechanism for cracks or stiffness.
Frequently Asked Questions
Should I replace my Burbank garage door’s extension springs with torsion springs for safety?
Yes—if your home still uses extension springs, upgrading to torsion springs is one of the safest moves you can make. Torsion springs fail more predictably and are less likely to cause injury. Burbank’s extreme temperatures also stress extension springs faster, making torsion springs a smarter long-term investment for your family’s safety.
Is it worth adding carbon monoxide-proof seals to my Burbank garage door?
Absolutely. If your garage is attached to your home, carbon monoxide from cars or appliances can seep in through gaps in the door. Burbank’s tight building codes require proper sealing, and high-quality weatherstripping with CO-resistant materials adds an extra layer of protection for your family’s health.
Do I really need to test my garage door’s photo-eye sensors every month in Burbank?
Yes—photo-eye sensors are your garage door’s last line of defense against accidents. Burbank’s bright sunlight can sometimes interfere with sensor alignment, and dust from our dry climate can block the beams. A quick monthly test ensures they’ll stop the door if a child or pet walks underneath.
