How To Tension A Garage Door Spring

How to Tension a Garage Door Spring (Without Launching Yourself Into Orbit)

Let’s face it—garage doors are like that one friend who’s chill 95% of the time but throws a spectacular tantrum when ignored. And nothing says “midlife crisis” like a broken spring turning your smooth-sailing door into a creaky, jerky nightmare. If you’re here, you’ve probably heard that ominous TWANG or noticed your door moving like it’s auditioning for a horror movie. Don’t panic—we’ve all been there. At San Francisco Garage Doors, we’ve tensioned more springs than we’ve had cups of Bay Area fog (and trust us, that’s saying something). Let’s break this down step-by-step, with a dash of humor and zero rocket science.

Why Garage Door Springs Matter (Spoiler: They’re the Unsung Heroes)

Garage door springs are the muscle behind the magic. They counterbalance the door’s weight, so your opener doesn’t burn out trying to lift what’s essentially a small car. There are two types:

• Torsion springs (mounted above the door, look like giant metal coils)
• Extension springs (run parallel to the tracks, stretchy bois)

FYI: If your door is suddenly heavier than your post-burrito guilt, you’ve likely got a spring issue. And no, ignoring it won’t make it go away—unless you enjoy replacing openers every six months.

Tools You’ll Need (Besides a Prayer)

Before you channel your inner MacGyver, grab these:

• Winding bars (not screwdrivers—they’ll slip and turn you into a human catapult)
• Vice grips
• Ladder
• Safety goggles (because eyes are kinda important)
• Gloves (springs bite harder than a seagull eyeing your sourdough)

Missing tools? San Francisco Garage Doors offers same-day garage door spring replacement and repairs. No judgment if you’d rather let pros handle the heavy lifting.

Step 1: Safety First (Unless You Enjoy ER Trips)

Garage door springs store enough energy to launch a small satellite. One wrong move and—well, let’s just say you won’t need that gym membership anymore. Here’s how to stay safe:

• Disconnect the opener. You don’t want it “helping” mid-repair.
• Clamp the door down with vice grips.
• Work with a buddy. Solo missions are for Netflix, not spring tensioning.

Pro Tip: If your springs are older than your favorite pair of jeans, skip the DIY and call us. Garage door coil spring repair isn’t worth a trip to urgent care.

Step 2: Tensioning Torsion Springs (The “Don’t Die” Edition)

Torsion springs are trickier than explaining TikTok to your grandparents. Here’s the play-by-play:

Find the winding cone

Locate the cone at the end of the spring. This is where you’ll insert the winding bars.

Count the turns

Most doors need 7–8 full turns for proper tension. Miss a quarter-turn? Congrats, your door now opens like a sloth on melatonin.

Wind slowly and evenly

Insert the bars, turn gradually, and keep your body out of the “kill zone” (the arc where bars could swing if they slip).

Warning: If you hear creaking or feel resistance, stop. That’s the spring saying, “Call San Francisco Garage Doors before I ruin your week.”

Step 3: Adjusting Extension Springs (The “Why Is This So Stretchy?” Phase)

Extension springs are simpler but still deserve respect. Here’s the drill:

1. Unhook the safety cable (it’s usually bright red, like a warning flag).
2. Adjust the S-hooks or pulleys to increase/decrease tension.
3. Reattach the safety cable.

IMO: If your springs look like they’ve been through a metal mosh pit, invest in garage door cable replacement too. Weak cables + tensioned springs = disaster waiting to happen.

When to Call the Pros (AKA Us)

Look, we get it—DIY is satisfying. But some jobs scream “nope” louder than a noisy garage door at 6 a.m. Call San Francisco Garage Doors if:

• The spring is snapped, rusted, or looks like modern art.
• Your door still jerks or struggles after adjustments.
• You’re sweating more than a tourist hiking Lombard Street.
