โš ๏ธ Broken Cable = Stop Using the Door Immediately

A garage door without both cables is extremely dangerous. The door can fall suddenly under its own weight โ€” typically 150โ€“400 lbs. Disconnect the opener using the red emergency release cord and do not attempt to manually operate the door until it's repaired.

How Much Does Garage Door Cable Repair Cost in North Alabama?

Garage door cable repair is one of the most common โ€” and most urgent โ€” repairs in North Alabama. Most homeowners pay $120โ€“$200 to have a professional replace a broken cable on a standard residential door. Here's the full breakdown:

JobCost RangeNotes
Single cable replacement Most Common $120โ€“$180 Always replace both even if one looks OK
Both cables replaced (recommended) $150โ€“$230 Matched pair โ€” prevents quick second failure
Cable + drum replacement $175โ€“$280 If the cable drum is cracked or grooved
Cable + spring combo repair $250โ€“$450 Often a broken spring causes the cable to slip
Emergency / after-hours service +$50โ€“$100 Added to standard repair price

Why Replace Both Cables At Once?

Garage door cables work in matched pairs. If one snaps, the other has endured the same wear and is close to failure. Replacing both during the same service call costs only marginally more โ€” around $30โ€“$50 extra โ€” and saves you a second service fee within weeks. Every reputable North Alabama contractor will recommend this.


What Causes Garage Door Cables to Break?

  • Age and wear โ€” cables fray over thousands of cycles; most last 7โ€“10 years
  • Broken spring โ€” when a spring snaps, it dumps all tension onto the cable, often breaking it too
  • Improper winding โ€” cable jumping off the drum puts uneven stress on one spot
  • Rust and corrosion โ€” North Alabama's humidity accelerates cable deterioration
  • Bottom bracket failure โ€” the bracket the cable attaches to can bend or break, causing slack
  • Door out of balance โ€” running an unbalanced door stresses cables unevenly

Signs Your Garage Door Cable is Failing

  • Visible fraying or rust on the cable wire
  • Door appears crooked or lopsided when opening
  • Loud snapping or popping sound from the garage
  • Loose cable coiled on the floor near the door
  • Door opens partially then stops or reverses
  • Opener motor strains but door barely moves

Garage Door Cable Types โ€” What Your Tech Will Use

Torsion Spring Cables

  • Run from bottom bracket up to drum
  • Wound around drums above the door
  • 7 ft or 8 ft depending on door height
  • 1/8" or 9/32" wire diameter common

Extension Spring Cables

  • Run through pulleys along sides
  • Attach to bottom bracket and pulley
  • Thinner gauge, different tension profile
  • Safety cable runs inside spring as backup

Can I Replace a Garage Door Cable Myself?

Extension spring cable replacement is within reach of a careful DIYer โ€” the spring tension is lower and the system is more forgiving. Torsion spring cable replacement is more dangerous because the springs remain wound under high tension during the job. One slip of the winding bar or cable drum can cause serious injury.

Frequently Asked Questions โ€” Cable Repair

My garage door cable snapped โ€” is it safe to park my car inside? +
If the door is fully closed and resting on the ground, your car is likely safe short-term. Do not attempt to open the door. If the door is partially open, do not park underneath it โ€” a door held open by a single cable can fall without warning. Call a technician immediately.
Did my spring break or my cable? How do I tell? +
Look above your door at the horizontal metal bar. If you see a gap in the tightly-wound spring coil, your spring broke โ€” and may have also taken out the cable. If the spring looks intact but there's a loose wire hanging or coiled near the bottom of the door, it's the cable. Often both need replacement together.
How long will a replacement cable last? +
Quality galvanized steel cables typically last 7โ€“10 years or 10,000+ open/close cycles under normal use. To extend cable life, lubricate the cable and drum once a year with a garage door lubricant spray โ€” do not use WD-40.
