Replacing a damaged garage door panel
Garage door panel replacement: can you swap just one panel?
On a sectional door, a single damaged panel can often be replaced on its own, provided a matching panel is still available for that door. On a roller door, the equivalent is replacing damaged laths or the curtain. On a one-piece up and over door there is no separate panel to change, so serious damage usually means a new door.
Panel damage usually comes from a car nudging the door, a storm, or a door that has been forced while off its track. Before anything is ordered, it is worth making sure the damage has not spread to the hinges, rollers or tracks, because a new panel on a bent door will not run properly.
- Sectional doors
- Individual panels can often be changed
- Roller doors
- Laths or curtain replaced
- Up and over
- One-piece leaf, rarely repairable
- Check first
- Tracks, hinges and rollers
How it works on each door type
The construction of the door decides what can be replaced.
| Door type | What can be replaced | Watch out for |
|---|---|---|
| Sectional | Individual panel, with its hinges | Colour and profile must match the other panels |
| Roller | Damaged laths or the full curtain | Curtain may need removing from the barrel |
| Up and over | Usually nothing separately | Leaf is one piece; bad dents mean replacement |
| Side-hinged | The damaged leaf | Matching finish to the other leaf |
Finding a matching panel
A replacement panel has to match the door in height, profile, surface finish and colour, and fit the same hinges. On a current door range that is usually straightforward. On an older or discontinued door it may be impossible to match exactly, and a mismatched panel is very obvious on the front of a house.
Colours also fade. Even a perfect match from the manufacturer can look slightly different next to panels that have been in the weather for years, particularly on darker colours.
When one panel is not worth it
In those cases the money spent on a panel is better put towards a new door. Our repair or replace guide goes through the decision in more detail.
- More than one or two panels are damaged.
- The door is old enough that springs, cables and rollers are also due.
- No matching panel is available and a patchwork finish is not acceptable.
- The impact has twisted the tracks or damaged the motor mounting.
Glazed and window panels
Some sectional doors have a row of vision panels to let light in. A cracked glazed insert can often be replaced on its own; where the whole panel is damaged, a matching glazed panel is needed. If you want to add windows to a solid door, it is usually done by swapping a solid panel for a glazed one from the same range, not by cutting into the existing panel, which would affect its strength and insulation.
Why this is not a DIY job
The bottom panel of a sectional door carries the cable brackets, and those cables are under spring tension. Removing that panel without releasing the tension safely can cause serious injury. Upper panels are less dangerous but still need the door locked off and supported. We handle panel replacement as part of our garage door repair service.
Questions we get asked
- Can I replace just the bottom panel of my garage door?
- Often, yes, if a matching panel is available. The bottom panel carries the cable brackets under spring tension, so it must be done by an engineer.
- My up and over door is dented. Can the panel be replaced?
- Up and over doors are usually one piece, so there is no separate panel. Minor dents can be lived with; serious damage generally means a new door.
- Can windows be added to my existing door?
- On many sectional doors, yes, by swapping a solid panel for a glazed one from the same range.
- What if a matching panel isn't made any more?
- Then the choice is a visible mismatch or a new door. We will tell you honestly which makes more sense.
