Dented or Cracked Garage Door Panel: Replace the Panel or the Door?

A single dented or cracked garage door section can often be replaced on its own, as long as the same section is still made, it will match the rest of the door, and nothing else was damaged. If two or more sections are damaged, the door is older, or the model has been discontinued, replacing the whole door is usually the better use of your money. The way to find out is to identify the door and check the damage properly.

Is it a panel or a section?

On most home garage doors, what people call a panel is really a full-width horizontal section, and the whole section is what gets replaced. A typical sectional door has four or five of these sections hinged together. The raised or recessed shapes you see on each section are pressed into the steel, so you cannot swap just one square; it is the full section or nothing.

Can you replace just one garage door section?

Yes, if a matching section is still available. The new section has to be the same make, model, width, height, thickness, design and colour, and on an insulated door the same insulation type. That is why the first step is identifying the door, usually from a label on the inside of a section or along its edge, or from the design and hinge layout.

When does replacing one section make sense?

Replacing one section makes sense when the damage is limited and the rest of the door is in good shape. Typical cases:

• One section dented by a car bumper, a ball or a snowblower, with the others straight.

• The door is fairly new and the model is still in production.

• The finish on the rest of the door has not faded much, so a new section will not stand out.

• The tracks, rollers and hinges are not bent.

When is a new door the better choice?

A new door is usually better when the damage is spread across sections, the door is old, or a matching section cannot be found. Typical cases:

• Two or more sections are dented, cracked or bent.

• The model has been discontinued, so a replacement section would be a different design.

• The door is faded, rusting or peeling, so a new section would look obviously different.

• The door is uninsulated and you were already thinking about insulation. Our comparison of insulated and uninsulated garage doors helps with that choice.

• The section, shipping and labour together come close to the cost of a new door.

Will a new section match the colour?

Not always exactly. Garage door finishes fade in the sun over the years, especially on south- and west-facing doors, so a brand-new section in the same factory colour can look slightly brighter than the rest. On white doors the difference is often hard to see; on darker colours and woodgrain finishes it is more noticeable. Some owners have the whole door painted afterwards to even it out.

Can a dented garage door panel be fixed instead of replaced?

Small, shallow dents in steel can sometimes be pushed out or filled and painted, but the result is rarely invisible, and a crease in the steel stays weaker. A cracked section, a section bent across its width, or one with a torn hinge mount should be replaced, not patched, because a damaged section can fold or bind as it rolls through the curve of the track.

Is it safe to use the door with a damaged section?

Only if the door still runs smoothly and evenly. If it catches, the opener strains, a roller has left the track, or the bent section rubs, stop using it. A car impact often bends the track or loosens hinges as well, and running the door like that can push it right out of the track; our article on a garage door off track explains what not to do.

What happens on the day a section is replaced?

The door is secured, the damaged section is unbolted from its hinges and lifted out, and the new one is fitted, hinged and adjusted. For the bottom section the lift cables have to come off, and for the top section the opener arm, so spring tension has to be handled properly. Afterwards the door is balanced, the rollers and hinges are checked, and the opener's force and travel settings are reset.

How long does it take to get a replacement section?

It depends on the door. Common sizes and designs can sometimes be sourced fairly quickly, while less common models or colours have to be ordered in, which can take a few weeks. If the door is not safe to run in the meantime, it can usually be secured so the garage still locks.
