If your top panel folds when the door opens, someone “fixed” it two months ago, and it’s folding again — the repair was probably wrong the first time. The usual culprit: a reinforcement strut installed across the middle of the panel instead of along its top edge, where the opener pulls.
What the strut does — and the one place it belongs
An automatic opener doesn’t lift a door evenly; it pulls hard on the center of the top section. A horizontal steel strut along the top edge of that section spreads the force across the door’s full width. Installed mid-panel, it reinforces the wrong line — the top edge keeps flexing above it, and the panel creases exactly where you’re seeing it crease. On heavier or wider doors, top-section struts aren’t optional; they’re standard practice.
Three signs your last repair was done wrong
- Strut position. Open the door and look: the strut should run along the very top of the top section, near the opener bracket — not across its middle.
- The opener pushes down instead of pulling in. If the operator arm is angled so it drives the door downward against the opening, the header bracket is set wrong — a common shortcut when a handyman hangs the opener.
- A new crease within weeks. Metal that’s been folded once is fatigued. A “panel swap” that reuses the same wrong strut layout just resets the countdown.
The honest parts math
A one-piece top strut from a garage door supplier costs about $50. As one Reddit commenter put it after living exactly this story: the part is $50 — some companies will still quote you $500 for the visit. At Right Choice, a strut repair is $305 flat — installation and tax included — plus an honest verdict on whether an already-creased section is done.
Renting? You still have leverage
If a leasing office keeps sending the same vendor for the same failing fix, put it in writing: the strut placement is against manufacturer installation standards, the repeated failure is documented, and you’re requesting a professional garage door company for the next visit. Property managers respond to paper trails.
Frequently asked questions
Is a creased panel dead?
Usually, structurally — a strut can brace it as a stopgap, but folded steel doesn’t get its strength back. Budget for a section replacement.
Can just one section be replaced?
Often yes, if the model is current. See our repair-or-replace guide for when it stops being worth it.
Will the opener need adjusting too?
Yes — force and travel limits should be reset after any panel or strut work, and the door’s balance checked. Skipping that is how the next panel bends.
