Replacing one damaged garage door section runs $250 to $1,000 installed in 2026, depending on door size, material, section position, and your region. A full door replacement, if the damage or the math pushes you there, runs $1,100 to $3,800 installed for a standard residential steel door. Which number you’re looking at comes down to four things: how many sections are damaged, how old the door is, what it’s made of, and whether your manufacturer still makes that section.
The short version: one or two damaged sections on a door less than 15 years old is usually a repair job. Three or more sections, or a door whose panels have been discontinued, usually tips the math toward a new door. For a full breakdown with source data, the complete lab on Garage Door Science covers both scenarios in detail.
Count the damaged sections first
One or two sections damaged: a section replacement is likely the right call. That $250 to $1,000 range is wide because a basic steel mid-section on a standard 16-foot door costs far less than a top section on an insulated carriage-house door. Getting a written quote from your door maker’s authorized dealer closes that range quickly.
Three or more sections damaged: at that point, manufacturers including Amarr and Overhead Door dealers generally say a new door system is the more economical choice. Ask for two written quotes side by side, one for the sections, one for full replacement, before you decide. The math often favors replacement faster than it looks, because section labor is charged per section and the cost compounds.
Check your door’s age before you order anything
Manufacturers don’t hold sections in inventory forever. Amarr puts the practical window at roughly 10 to 15 years; Overhead Door dealers note that doors approaching 15 to 20 years old may no longer have matching sections available. Call your door maker’s dealer, give them the model number from the label on the inside of the bottom section, and ask whether that panel still exists. If it doesn’t, you’re choosing between a new door and living with the dent.
Climate adds a layer here. In freeze-thaw regions, older steel panels often show stress corrosion at the joints that doesn’t appear in a quick visual scan. In humid coastal environments, the same-age door may have corrosion on the bottom two sections that changes the repair calculation entirely. A technician who sees the door in person will catch what a photo won’t.
Wood doors and carriage-house styles are a special case
Natural wood doors are harder to patch with a single section. Some manufacturers, Overhead Door among them, offer only full door replacement for natural wood. Custom carriage-house designs present similar challenges because the panel profile, hardware cutouts, and decorative elements are often proprietary. If your door has decorative hinges or handles on the damaged section, those need replacing too, and the quote should include them.
If you’re not sure whether you have a long-panel or short-panel design, that distinction matters when you describe the door to a dealer. The Long Panel vs. Short Panel guide on this site shows the visual difference clearly.
The color match problem
A new panel comes from the factory with fresh paint or finish. Your existing door has years of UV exposure. Amarr notes directly that new sections may not match older sections because colors fade over time. Ask the dealer upfront how close the match will be on a door your age. That conversation costs nothing. Finding out after the install does.
How to order the right section
- The door brand and model number, on a label inside the bottom section.
- The section position: top, middle, or bottom.
- The section dimensions: height and width.
- The color name or code, if listed on the label.
- For Clopay doors made in the last ten years: a 15 to 16 digit serial number printed on the inside of the bottom section.
Stick to your door’s own brand. Sections from different manufacturers use different joint profiles, and mixing them can create pinch hazards, weather gaps, and binding. Buying a section online before talking to a professional risks getting the wrong size, wrong color, or wrong style, and Amarr notes that having a dealer-network technician do the swap is what keeps the door under warranty.
The swap is not a homeowner job
Removing a section means working around torsion springs and lift cables under high stored tension. Those components do not become safe because the door looks stationary. Do not try to remove a section yourself, and do not force or manually lower a dented door to get it moving again. If the dent bent the door frame or contacted the tracks, cables, or bottom brackets, stop using the door entirely and call a technician before anything else.
A trained technician from your door maker’s authorized dealer does this work, the same person who can confirm parts availability, assess whether the tracks took any damage in the incident, and handle the warranty paperwork. If you want to understand where those components sit before the technician arrives, the parts diagram on Garage Door Science labels each one.
What to do this week
- Count the damaged sections. One or two: get a section quote. Three or more: get a section quote and a new-door quote at the same time.
- If the dent bent the door or touched the tracks, cables, or bottom brackets, stop using the door and call now.
- Find the label on the inside of the bottom section. Note the brand, model, section position, dimensions, and color.
- Call your door maker’s authorized dealer. Ask whether your section is still made, how close the color match will be, and whether decorative hardware is included in the quote.
- Put the section quote next to the new-door quote. If the section repair costs more than 40 to 50 percent of a new door installed, the new door is almost always the better spend.

Frequently Asked Questions
Can I replace just one panel on my garage door without replacing the whole door?
Yes, in many cases. One or two damaged sections on a door less than 15 years old is usually a viable repair, provided your door’s manufacturer still makes that panel. Once three or more sections are damaged, or the door is old enough that sections are discontinued, a full replacement typically becomes the more economical choice. Your door maker’s authorized dealer can confirm parts availability before you commit to either option.
How much does it cost to replace a single garage door panel?
Panel replacement typically runs $250 to $1,000, depending on section size, position, material, insulation, and your region. A basic steel mid-section on a standard door sits at the lower end of that range; a top section on an insulated or carriage-house door runs higher. Get a written quote from your door maker’s dealer, not a generic online estimate, because the labor and part cost vary significantly by brand and door type.
What happens if I can’t find a matching replacement panel for my garage door?
If the manufacturer no longer makes your section, you’re choosing between a new door and leaving the dent in place. Most manufacturers stop stocking panels for doors roughly 15 to 20 years old, though the cutoff varies by brand. A dealer can tell you within minutes whether your section is still available. If it’s not, pricing out a new door is the logical next step.
Will a new garage door panel match the color of my existing door?
Probably not perfectly. A new panel arrives with fresh factory finish; your existing door has years of UV exposure and weathering. How visible the difference is depends on your door’s age, color, and how much sun it sees. Ask the dealer directly how close the match will be before you approve the work, especially on older doors or in hot-dry climates where fading accelerates.
Is it safe to replace a garage door panel myself?
No. Removing a section requires working around torsion springs and lift cables that remain under high tension even when the door is closed. This is not a job where caution is enough; the stored energy in those components can cause serious injury if a spring or cable shifts unexpectedly. A trained technician from your door maker’s authorized dealer handles this work. Attempting it yourself also typically voids the door’s warranty.
When should I stop using my garage door after a dent and call a technician immediately?
Stop using the door if the dent bent the door’s frame, or if the damage contacted the tracks, cables, or bottom brackets. Those components interact directly with the spring and cable system, and a bent track or stressed cable can fail without warning. Leave the door where it is and call a technician before operating it again. A visual inspection of the panel is not enough to confirm the hardware is still safe.
