Garage door spring repair can be a bit tricky and potentially dangerous if you’re not experienced with it. Here’s a general overview of what’s involved:

1. Identify the Problem: Determine whether it’s a torsion spring or an extension spring that needs repair or replacement. Torsion springs are usually mounted above the door, while extension springs are on either side of the door.

2. Safety First: Before you begin any work, make sure to disable the opener so the door can’t accidentally be activated. Additionally, always wear safety glasses and gloves, as dealing with springs can be risky.

3. Release Tension: If it’s a torsion spring, you’ll need to release the tension in the spring before attempting any repairs. This typically involves using winding bars to unwind the spring carefully. Extension springs don’t typically need to be manually unwound.

4. Replace the Spring: Once the tension is released, you can remove the old spring and install a new one. Make sure to get the correct size and type of spring for your door.

5. Reattach Cables and Hardware: After installing the new spring, reattach any cables or hardware that may have been disconnected during the process.

6. Test the Door: Once everything is back in place, test the door to ensure it opens and closes smoothly. Make any necessary adjustments to the tension or alignment if needed.

If you’re not comfortable or experienced with garage door spring repairs, it’s usually best to leave it to the professionals. Working with garage door springs can be dangerous, and it’s easy to make mistakes that could cause injury or further damage to your door. Hiring a professional ensures the job is done safely and correctly.
