Garage Door Repair Desk is a library of 51 practical guides on springs, openers, tracks, panels, and the rest of the door. Each one helps you tell what failed, judge whether a quote is fair, and know which jobs are safe to do yourself.
Four signs a torsion spring has failed
The door suddenly feels far too heavy to lift by hand.
You heard a loud bang from the garage, like a firecracker going off.
A lifting cable hangs loose, or there is a two-inch gap in the spring coil.
The opener strains and hums, but the door barely moves.
A torsion spring holds hundreds of pounds of tension. Replacing one is not a DIY job. A slip can cause serious injury, so this repair belongs with a trained technician.
Every guide sits in one of 5 topics. Start where the trouble is.
Springs, cables, openers, sensors, and doors that jump the track.
New doors, new openers, and when a single panel will do.
How the parts work and how to hire someone who will not overcharge.
The yearly tune-up that keeps a door running quietly for years.
Stuck open overnight or a snapped spring, and what to do right now.
Does a new garage door increase home value? What the Cost vs. Value data measures, why a national average won't match your house, and when replacing pays.

In the 2025 Cost vs. Value Report, the national average was $12,507 in estimated resale value on a $4,672 job (267.7 percent). Your local market, the door you pick and the door you replace all move that. Look up your own metro in the report.
Sections joined by numbered hinges, stiffened by struts, held by a top fixture and bottom brackets. The counterbalance is the springs, lift cables, cable drums and torsion shaft. The door rides on rollers in vertical and horizontal track, and the opener adds a motor unit, rail, trolley and emergency release.
No, and you should not try. The springs carry almost all of the door's weight, so a door with a snapped torsion spring is dead weight of roughly 150 to 350 pounds on a double door. Pulling the release cord will not make it lighter. If the door will not rise with steady two-handed effort, or rises a few inches and slams back down, stop and call a technician.
A basic lubrication and visual inspection typically runs $75 to $120. A full multi-point tune-up that adds balance testing, opener calibration, and safety sensor checks usually costs $100 to $250. Exact pricing depends on door size, hardware condition, and local labor rates.
About $75 to $150 for one sensor, or $150 to $300 for both as a pair, including labor. Wiring condition and whether a brand-matched part is needed move the price.
