Most garage door problems -- broken springs, malfunctioning openers, off-track panels -- are repairable at reasonable cost. But there are situations where replacement is the smarter investment. Here's how to tell the difference.
Always repair: springs, cables, and hardware
Broken springs, snapped cables, bent tracks, and failed openers are all component failures -- not whole-system failures. A broken torsion spring costs $200-$350 to replace. An opener replacement runs $300-$500. These repairs on an otherwise sound door make complete financial sense.
Consider replacement: extensive panel damage
If multiple panels are dented, cracked, or warped from vehicle impact or storm damage, panel replacement can approach the cost of a new door. A single damaged panel runs $200-$400. Three damaged panels might cost $600-$1,200 -- at which point a new door at $1,000-$2,000 offers a better outcome.
Replace: doors over 20 years old showing rust or rot
Steel doors that have rusted through or wood doors with rot compromise insulation and security. The structural integrity of aged doors degrades, making them less energy efficient and easier to breach. A new insulated steel door dramatically improves home energy efficiency.
Security and insulation upgrades
Modern insulated garage doors have R-values of 9-18, compared to R-2 for older uninsulated doors. If your garage is attached to your home, that insulation difference is significant. New doors also include better sealing at the bottom and sides, reducing drafts in attached garages.
Bottom line
Repair springs, cables, openers, and single damaged panels. Replace when multiple panels are damaged, the door is rusting through, or the door is over 20 years old and showing real wear.
