Repair or component replacement is likely when

Continuous hinge, door slab or frame replacement is considered when the confirmed wear or damage makes adjustment unreliable.

Questions about Commercial Door Sagging, Dragging or Rubbing
Why is my commercial door sagging?
Common causes include worn hinges or pivots, loose attachment, frame movement, a damaged slab or support that no longer carries the door correctly. The complete opening should be checked before a component is selected.
Can a dragging commercial door be adjusted?
Sometimes. Adjustment may help when the hinges, pivots, frame and slab remain serviceable. Repeated sagging or loose attachment may require component replacement or a continuous hinge.
When is a continuous hinge recommended?
A full-height continuous geared hinge may be considered for a heavy or high-use door when the frame, door and attachment conditions can support the installation.
Can you replace commercial hinges, pivots or thresholds?
Yes. Once the cause and compatibility are confirmed, we can repair, replace or install compatible hinges, pivots, continuous hinges and thresholds.
What if the door or frame is already damaged?
We assess whether the slab, frame or complete opening needs replacement, then match the work to the aluminum storefront, hollow metal, fire-rated or general commercial door system.
Understand the repair before choosing the hardware
A door that rubs may need adjustment, replacement support hardware or work on the frame. Our guide to why commercial doors sag and how we choose the repair compares those decisions using four completed DoorWin projects.
