Types of Garage Door Springs

Garage doors typically utilize one of two types of springs: torsion springs and extension springs.

Torsion Springs:

  • Mounted above the garage door opening.
  • Utilize torque to lift and lower the door.
  • Longer lifespan and can support heavier doors.
  • Superior in balance and provide smoother motion.
  • Available in different sizes to match door weight and size.

Extension Springs:

  • Located on either side of the door, parallel to the tracks.
  • Extend and contract to open and close the door.
  • Require safety cables to prevent injury if a spring breaks.
  • More common on lighter doors and in older garage installations.
  • Generally, they have a shorter lifespan and can be less expensive than torsion springs.

Both types of springs are under high tension and can be dangerous if not handled properly. Understanding the specific type fitted to your garage door is crucial before considering repair or replacement.

Symptoms of Failing Springs

Recognizing the warning signs of malfunctioning garage door springs can prevent accidents and further damage. A door that closes too quickly, often with a loud bang, may indicate weakened tension in the springs. If the door appears crooked when it moves or struggles to open evenly, this could also suggest spring wear or damage.

When opening, a garage door should not feel heavy. Springs are designed to counterbalance the weight, so a door that seems unusually heavy to lift points to compromised springs. A telltale sign of a broken spring is a noticeable gap, typically about two inches, in the spring’s coils.

Additionally, pay attention to the sound your garage door makes. Springs in good condition should not be noisy. Persistent creaking or grating sounds can be indicative of springs that are on their last legs and require attention. Regularly inspecting your garage door system increases the chance of catching these symptoms early, maintaining safety, and reducing the likelihood of unexpected disruptions to your garage’s functionality.

Safety Considerations in Repair

Garage door springs are under high tension and can cause serious injury if not handled properly. Prior to attempting repairs, ensure the garage door is in the closed position, secured so that it can’t roll down unexpectedly.

Use only the proper tools, like winding bars, to adjust or replace springs – never improvised items like screwdrivers. Always wear safety glasses and gloves for protection.

Keep in mind that torsion springs, in particular, pose a greater risk due to the immense force they are under. If you’re not experienced with mechanical repairs or you’re not comfortable with the risks involved, seeking professional assistance is the safest option.

Disconnect the garage door opener to prevent accidental activation while working on the springs. Remember, double-checking each safety step can significantly reduce the risk of accidents during spring repair.

DIY Vs. Professional Garage Door Spring Replacement

Embarking on a DIY garage door spring repair can be tempting for those who are handy, as it can save on costs. However, this task requires a clear understanding of spring mechanisms and the right tools. Springs are under tremendous tension, and incorrect handling can lead to injury or further damage to your garage system. DIY is feasible for those with mechanical experience, a full understanding of the risks, and the necessary safety equipment.

In contrast, hiring professionals ensures that the replacement is done safely and correctly. Experts have specialized tools and knowledge to handle torsion and extension springs. They can also identify additional issues that may not be apparent to a homeowner. Furthermore, professional services often come with warranties, providing peace of mind that the repair is guaranteed.

For those weighing these options, consider the complexity of the task, the potential hazards, and the value of the time and effort you would invest in a DIY repair. If the risks and learning curve seem daunting, or if the proper tools are not readily available, professional services may be the prudent choice.

How to Hire a Professional

When selecting a technician for garage door spring replacement, verify their credentials first. Look for licensure and insurance to ensure they’re authorized to perform the work and protect against liability. Check their experience specifically with garage door systems, as this area requires precise knowledge and skill.

Investigate their reputation through reviews and testimonials, which reflect the quality of their service and customer satisfaction. This information can often be found on the company’s website or through independent platforms like Google Reviews or Yelp.

Request a detailed quote to understand the cost breakdown and avoid hidden charges. Compare these quotes from different service providers to find a balance between affordability and quality.

Finally, inquire about the warranty or guarantee on their work. A reliable professional will stand behind their service with a certain period of coverage for the repairs done. This gives peace of mind and can save on future costs if issues arise.
