Why Spring Tension Matters

Spring tension keeps your garage door balanced and working smoothly. Too tight? The door rockets up. Too loose? It slumps down. Both scenarios put stress on other components like the opener, which could lead to bigger issues down the line. Regular checks are crucial, especially for high-use doors, so let’s get those springs in shape.

Tools You’ll Need

  • Winding bars (for torsion springs)
  • Adjustable wrench
  • C-clamps or locking pliers
  • Safety glasses and gloves

Step-by-Step: How to Check Your Garage Door Spring Tension

1. Disconnect the Garage Door Opener

Start by pulling that emergency release cord. This lets you work without the motor accidentally kicking in.

2. Test the Door’s Balance

Manually lift the door halfway and release it. If it stays, great! If it shifts, you’ve got a tension problem. The door dropping? You need more tension. Rising up? There’s too much tension.

3. Adjust Torsion Springs (If Applicable)

For torsion springs, place winding bars in the winding cone, turning them one-quarter turn at a time. Test the door after each turn to avoid over-adjusting, which could worsen the balance.

4. Adjust Extension Springs

Check both sides for even tension. Use the pulley and safety cable to make small adjustments, balancing the door.

5. Reattach and Test the Opener

Once tension seems balanced, reconnect the opener and run a full cycle. A smooth operation means you’re good to go.

FAQ’s

What causes garage door springs to lose tension?

Springs can lose tension from everyday wear or changes in door weight, like adding insulation. Over time, springs stretch, reducing their lifting power. Regular checks and adjustments help maintain smooth function.

Can I check garage door spring tension on my own?

Yes, but only if you’re confident. Springs are under high tension, and one misstep could cause serious injury. If in doubt, reach out to the pros—Garage Door Pros San Francisco is here to keep your setup safe and sound.

How often should I check my garage door springs?

Aim for at least once a year, though every six months is ideal if you use your door often. Listen for unusual sounds and watch for uneven movement. Quick checks mean catching problems before they escalate.

Why does my garage door slam shut when closing?

A slamming door indicates too much tension. When tension builds up, it pushes the door down too forcefully. Reducing torsion or extension spring tension should resolve this. For a door that won’t stay open, tighten things up a bit instead.

Safety First: Essential Precautions

Before you start, remember that garage door springs hold tons of force. Always wear protective gloves and goggles, and ensure the opener is disconnected. Adjustments should be small, so keep your grip firm but cautious. If anything feels off, get professional assistance—Garage Door Pros San Francisco can handle all your adjustments safely.
