Should you repair or replace your garage door?
Updated August 2026
← Every repair-or-replace call
A snapped spring, frayed cable, or worn roller is a $100–350 repair and never a reason to buy a door; replace the door itself when panels are dented through, rotted, or the door is past 20–30 years. Hardware is consumable. Torsion springs are rated in cycles, commonly 10,000, which is about seven years at four openings a day, and rollers, hinges, and cables wear on a similar clock. A new sectional door installed runs $800–2,500, more for insulated or custom panels. One firm warning: never touch a torsion spring yourself.
The short version
Separate the door from the machinery that moves it. Panels, hinges, springs, cables, rollers, and the opener are each replaceable on their own, and the door slab is usually the last piece to fail. A spring breaks with a bang and the door will not lift, which feels catastrophic and costs $150–350 to fix with both springs done together. Cables fray and get swapped for $125–250. Nylon rollers run $100–200 for a full set and quiet the whole door. The slab earns replacement on three grounds: panels dented past straightening after a bumper, wood sections rotted at the bottom rail, or a door old enough that matching sections are discontinued and every repair becomes a scavenger hunt. Comfort is the fourth, since an uninsulated door on an attached garage bleeds heat out of a room you may want to use.
Your situation, decided
| Situation | Verdict | Why |
|---|---|---|
| Broken torsion spring, panels straight | Repair | A $150–350 pro spring job on a door with life left |
| Frayed cable or noisy steel rollers | Repair | Cables at $125–250, a nylon roller set at $100–200 |
| One panel dented, matching section available | Repair | A single panel swap costs far less than an $800–2,500 door |
| Bottom sections rotted on a wood door | Replace | Rot travels along the rail; new panels sit on bad wood |
| Uninsulated door on a garage you heat | Replace | An insulated door at $1,200–2,500 pays back in comfort |
| Past 25 years, sections discontinued | Replace | Hunting obsolete parts costs more over time than a new door |
What each path costs
Repairs typically run $100–350; a replacement is $800–2,500 installed. A steel sectional door lasts 20–30 years, but the springs inside it are rated for 10,000 cycles, roughly seven years of normal use. Hardware is the repair; the slab is the replacement. Price your own number on the home maintenance cost calculator before you commit either way.
The repair-or-replace call is easy when you know the unit's age and service history. OnOtto keeps both, plus the maintenance that delays this decision for years.

Can I change a garage door spring myself?
Torsion springs store enough energy to break bones, and they are wound with steel bars while under load, so this is the one garage job to hand over. A pro replaces a pair for $150–350 including labor, usually inside an hour, and arrives with the correct wire size and length. Extension springs running alongside the tracks are somewhat less dangerous but still need safety cables. If your springs are original on a decade-old door, book the replacement before one lets go.
If one spring breaks, should both be replaced?
Yes, on a two-spring door. Both have taken the same number of cycles, so the survivor is typically weeks or months from failing, and a second service call means another trip charge. Doing the pair adds maybe $75–150 to the bill. A mismatched pair, one fresh and one tired, also loads the opener unevenly and grinds its drive gear early. Ask about the cycle rating while you are at it: a 20,000-cycle spring costs a little more and lasts roughly twice as long.
Is an insulated garage door worth the upgrade?
On an attached garage, or one you actually work in, usually yes. An insulated sectional door costs roughly $300–800 more than a bare steel one and carries an R-value around 6–18 depending on construction, and the sandwich build is also stiffer, quieter, and harder to dent. On a detached, unheated garage it changes little beyond noise. Either way, skipped upkeep costs more than the upgrade, as neglected door hardware shows.
