Dented garage door panel: can you replace just one section, or do you need a new door?
A car or a mower dented one panel. Here is what an Overhead Door dealer, Clopay and Amarr say about buying a single section, how to order the right one, and when a new door is the better buy.
Yes, you can often replace just the dented section. It works best when one or two sections are damaged and your door is a current model you can still order. Once three or more are damaged, or your door is old enough that its sections are no longer made, a new door is usually the better buy.
Either way, the swap itself is not a homeowner job. A section is part of a door held up by springs and cables under high tension, so it belongs to a trained technician from your door maker's dealer.
Find the situation below that matches your door.
One or two sections are damaged
This is the case where buying a single section makes sense. An Overhead Door dealer's replacement sections page says replacing one or two damaged sections is significantly cheaper than replacing the whole door. That fits our repair or replace guide, which says one dented panel with the panels around it intact is a repair job, not a reason for a new door.
For a rough price, HomeAdvisor's repair-cost page puts a panel replacement at $250 to $1,000. Why the range is so wide is covered in our repair cost guide.
What to do: find your door's label or serial number (see "How to order the right section" below) and call your door maker's dealer for a quote on the section.
When to call a pro: always, for the swap. You can gather the details, but leave the work to the technician.
Three or more sections are damaged
Here the math usually flips. An Overhead Door dealer's replacement sections page says that once three or more panels are crushed, a new door system is usually more economical. Amarr's panel article also suggests thinking about a new door when more than two panels have serious damage.
What to do: ask for two written quotes, one for the sections and one for a new door. Our replacement guide walks through what a new door involves, and our damaged or aging door guide lays out the options side by side.
When to call a pro: before you use the door again if the damage bent the door out of shape or pulled at the tracks, cables or bottom brackets. Leave the door where it is and call.
Your door is older
Check your door's age first. The makers put the cutoff in different places, so take each figure as that maker's own.
- Amarr's panel article says a section swap is much simpler on a door bought within about the last 10 to 15 years, and that older doors may be hard to exchange if the style or color has been discontinued.
- An Overhead Door dealer's replacement sections page says matching panels are easy to source for a current model, but on a discontinued door roughly 15 to 20 years old, sections may no longer be available.
Your own door maker's dealer is the one who can say whether your section still exists. Ask them first, before you price anything else.
What to do: if the dealer says the section is discontinued, you are choosing between a new door and living with the dent. Our repair or replace guide helps you weigh it.
You have a wood door or a carriage-house style
These can be harder to patch with one section. An Overhead Door dealer's replacement sections page says that for natural wood doors it offers only full door replacement. Clopay's panel article says some custom carriage-house designs make single-panel replacement harder.
There is also the hardware. Amarr's panel article says that if the damaged section has decorative hinges and handles, those need replacing too.
What to do: ask the dealer whether your exact design is still made, and whether the quote includes the decorative hardware.
The new section may not match
A new section is fresh from the factory. The rest of your door has had years of sun. Amarr's panel article says a new section may not match older sections because colors fade over time.
The look of the door matters here too. If you are not sure which style you have, our long panel vs short panel guide shows the difference, which helps when you describe your door to a dealer.
What to do: ask the dealer how close the match will be on a door your age, and decide whether a slightly different shade on one section bothers you before you pay for it.
How to order the right section
Start with the information the makers ask for.
- Clopay's panel article says to tell the dealer the door model, the size of the section, the color, and whether you need the top, bottom or middle section.
- Clopay's same article says a Clopay door made in the past ten years has a 15 to 16 digit serial number on the inside of the bottom section.
- Amarr's panel article says the length, width and height of the section and the door brand are what you need.
Stick to your door's own brand. An Overhead Door dealer's replacement sections page says swapping in a section from a different maker generally does not work, because each maker designs its own joints between sections and mixing them can cause pinch hazards, weather leaks and binding.
Be careful about buying online. Amarr's panel article says shopping online before you talk to a professional can get you the wrong size, color or style. Amarr's same article says having a professional from its dealer network do the exchange keeps the door covered under warranty.
Who does the swap
A trained technician from your door's dealer. Taking a section out means working around the springs, the lift cables and the bottom brackets, and those hold a lot of stored force. Do not try it yourself, and do not push, force or lower a dented door by hand to get it working. If you want to see where those parts sit on your door, our parts diagram shows them.
What to do this week
- Count the damaged sections. One or two, keep reading. Three or more, ask for a new-door quote alongside the section quote.
- If the dent bent the door or touched the tracks, cables or bottom brackets, stop using the door and call a technician.
- Find the label or serial number on the inside of your door, and note the size, color and position of the damaged section.
- Call your door maker's dealer. Ask whether your section is still made, how close the color will be, and whether decorative hardware is included.
- Compare the section quote with a new-door quote, using our repair cost guide and our repair or replace guide to weigh them.
