We’ve all been there: you’re halfway through your morning coffee when BANG—your garage door starts sounding like it’s auditioning for a role in a haunted house. Nine times out of ten, uneven or loose cables are the culprits behind the drama. But before you panic (or worse, grab a ladder and a wrench without a plan), let’s walk through how to adjust garage door cable tension safely and effectively. And hey, if you’d rather leave the heavy lifting to pros who eat springs for breakfast, Marksman Garage Doors is just a call away.
Why Garage Door Cable Tension Actually Matters
Let’s cut to the chase: garage doors are basically giant, heavy puzzles held together by cables, springs, and a prayer. The cables are the unsung heroes that keep everything balanced. Too loose? Your door might slam shut like it’s got a vendetta. Too tight? You’re one misstep away from a snapped cable and a very bad day.
Here’s what happens when tension goes rogue:
- Uneven movement: One side of the door hangs lower, like it’s doing the limbo.
- Strange noises: Grinding, popping, or that ominous twang that makes your dog hide under the couch.
- Premature wear: Components like rollers and springs work harder, shortening their lifespan.
At Marksman Garage Doors, we’ve seen it all—including a door that sagged so much it became a makeshift ramp for squirrels. Trust us: balanced cables aren’t just a “nice-to-have.”
Safety First (Or This Could Get Real Ugly)
Look, we’re all for DIY spirit, but garage doors are not the place to channel your inner MacGyver. Those springs and cables store enough energy to turn a casual fix into an ER trip. So, let’s get serious for a hot second:
Your Safety Checklist
- Wear gloves and safety glasses: Because metal splinters are nobody’s idea of fun.
- Disconnect the opener: Unless you want the door to suddenly decide it’s showtime.
- Use locking pliers: Secure the door track to prevent accidental drops.
- Work with a buddy: Four eyes > two eyes when dealing with heavy machinery.
Still feeling jittery? No shame in tapping out and calling Marksman Garage Doors. We’ve got tools, training, and a zero-judgment policy for DIY refugees.
Step-by-Step: Adjusting Cable Tension Like a Pro
Alright, adrenaline junkies—let’s do this. FYI, these steps apply to extension spring systems (the ones with springs running parallel to the tracks). If you’ve got torsion springs (mounted above the door), put the wrench down and call us. Those things are not beginner-friendly.
Tools You’ll Need
- Adjustable wrench
- Stepladder
- Vice grips or locking pliers
- Socket set
- A calm disposition
The Process
- Secure the door: Lift it manually until it’s fully open, then clamp locking pliers below the bottom roller to keep it in place.
- Locate the adjustment cables: They’re attached to the springs on either side of the door.
- Loosen the cable bolts: Use your wrench to loosen (but don’t remove!) the bolts on the cable’s pulley system.
- Adjust tension evenly: Turn the bolts slowly—1/4 turn at a time—on both sides. Think “gentle tweaks,” not “Hulk smash.”
- Test the balance: Release the pliers and lower the door halfway. If it stays put, you’ve nailed it. If it moves, repeat steps 3–4.
Pro tip from our Marksman team: If one side keeps slipping, the cable might be frayed. Replace it ASAP before playing tension Tetris again.
Common Mistakes (And How to Avoid Them)
Let’s be real: we’ve all messed up a DIY project while swearing it’s “definitely fine.” Here’s what not to do with garage door cables:
- Over-tightening: This isn’t arm day at the gym. Too much tension = snapped cables.
- Ignoring wear and tear: Frayed cables? Replace them. Today.
- Adjusting one side only: Unless you want your door to resemble the Leaning Tower of Pisa.
Fun fact: 80% of the “emergency” calls we get at Marksman Garage Doors start with, “So, I tried adjusting the cables myself…”
When to Throw in the Towel and Call Marksman Garage Doors
Adjusting cables is like assembling IKEA furniture: straightforward until it’s very much not. Here’s when to hit pause and dial our number:

- Cables are damaged: You wouldn’t drive on bald tires—don’t gamble with frayed cables.
- The door still acts possessed: If adjustments don’t fix the issue, something bigger’s at play.
We’ll show up fast, fix it right, and even stick around to admire your (now silent) garage door with you.
FAQ: Your Burning Questions, Answered
How often should I check my garage door cables?
Give them a visual once-a-month once-over. Full tension checks? Maybe once a year—or whenever your door starts sounding like a Metallica concert.
Can I reuse old cables?
IMO, nope. Cables are cheap; hospital bills aren’t.
Why does my door still sag after adjusting?
Likely a deeper issue, like worn springs or track misalignment. Time to call in reinforcements (hi, we’re Marksman).
