Garage Door Panel Replacement
The inside face of one section has started to bow outward and the outer skin has a soft, wavy look. Tap it and it sounds hollow in places.
Garage Door Panel Replacement
In plain words
Not all sections are equal. The bottom section carries the brackets that anchor the lift cables, the seal that meets the floor, and most of the abuse from ice, salt and bumpers. The top section takes the pull of the opener arm and often carries a strut. The intermediate sections mostly carry hinges and rollers. Which position is damaged shapes the whole job: a bottom section means releasing spring tension before the brackets come off, a top section means dealing with the opener bracket and top fixtures, and a middle section is the most straightforward exchange. The technician plans the visit around that position.
How the visit goesThe top section has developed a bend where the opener arm pulls on it. On the way up it flexes visibly, the door hesitates near the top of its travel, and daylight shows through the joint below it when the door is closed.

How the visit goes
What the impact did to everything else
Trade-association guidance is clear that after a vehicle strike, a storm or a freeze-up the whole door is looked at, not just the dented part. The technician runs a hand along the hinges for cracks and pulled screws, spins each roller for flat spots and bent stems, sights down both tracks for kinks and checks the brackets that hold them to the jambs. Cables are inspected for fraying where they wrap the drums, spring anchors and the centre bearing plate are checked, and the opener arm and its bracket are examined for bending. Anything the impact disturbed goes on the list alongside the section.
Releasing tension for a bottom section
The bottom section is the one place where the lift cables attach, and those cables are held taut by the springs. Before its brackets are unbolted, the technician takes the energy out of the system. On a torsion door that means fitting winding bars into the cone and unwinding the spring turn by turn while the set screws are loosened; on an extension-spring door it means propping the door open and unhooking the springs. With the cables slack, the bottom brackets, the seal retainer and the section itself can be removed safely. The same steps are reversed at the end, and the door's balance is set fresh.
A door that runs as one piece again
When the work is finished the new section is indistinguishable in the way the door moves. The joints close tight with no daylight, the door rises without the shudder or catch that gave the damage away, and it sits level on the floor with the seal compressed evenly across its width. The technician walks you through the cycle with the opener and by hand so you can see the balance for yourself, points out the hinges and rollers that were replaced, and leaves the old section for disposal or takes it away as you prefer. Any temporary bracing from the first visit is gone.

What affects the quote
Same fees day, night or weekend
1Special-order handling and freight
Made-to-order sections travel from the factory or distributor, and a long or glazed section needs careful handling in transit. Freight and order handling are shown as their own line rather than folded into labour.
2Whether the exact section is still made
A current model is a straightforward order. A discontinued design may mean a section from a related series, a custom-made section, or a discussion about the whole door, each of which lands differently on the quote.
3Door width and section size
A section for a double door is nearly twice the length of one for a single door, with more steel, more hinges and a heavier lift. Section height and thickness feed into the same line.
Garage Door Panel Replacement: questions
Why is the bottom section handled differently from the others?
The bottom section is where the lift cables attach, through the bottom brackets at each end, and those cables are under the full pull of the springs. Before the brackets come off, the springs have to be unwound or unhooked so the cables go slack. The bottom section also carries the seal retainer and astragal that meet the floor. After the new section is in, the springs are re-tensioned and the balance reset.
The car has just hit the door. What should I do before you arrive?
Stop using the door and leave it where it is, whether open or closed, unless leaving it open is unsafe. Pull the opener's plug so nobody presses a remote out of habit. Keep people and pets clear, especially if the door hangs unevenly or a cable looks loose, since the springs are still under tension. Take a few photographs, find the manufacturer's label if you can, and tell the technician exactly what happened and how hard the contact was.
What is a strut, and does a new section need one?
A strut is a horizontal steel stiffener fastened across the inside of a section to keep it from bowing. Wide doors, top sections where the opener arm pulls, and bottom sections that take knocks are the usual places for them. If your damaged section had a strut, the new one gets a straight strut refitted or replaced. If a top section bowed because it never had one, adding a strut is part of putting it right.
