Commercial sectional doors ride one of a few track layouts. Standard-lift track turns the door back under the ceiling just above the opening, high-lift track runs it up the wall before it turns, and vertical-lift track carries the door straight up the wall. Repair matches new track lengths to the layout your door already uses.

Commercial Sectional Door Repair in Carrollton, TX
Your commercial sectional door took a hit from a trailer or a forklift, its track bent at the dock, or a section has come off its rollers. Commercial sectional door repair matches new sections to the door, realigns the track and sets the balance so the door lifts level again. Close off that bay, keep loading at the other doors, and call about repair for your Carrollton dock.
What you are seeing
Signs your commercial sectional door needs repair
Sectional doors along a dock take most of their damage from trailers and lift trucks, and the signs show in the panels and the track.
- Caved-in bottom section
A trailer corner or a lift-truck mast caved the first panel in.
- Bent vertical track
A hit at the side of the opening pushed the track out of line.
- Off its rollers
One side of the door has left the track and hangs askew.
- Torn hinges
Hinge leaves between sections have torn, so the door wobbles going up.
- Shattered vision lites
The glazing in a top section has cracked or dropped out.
- Daylight at the floor line
A bowed first section leaves daylight under the closed door.
Close the struck bay and route freight to your other doors, then call while the damage sits in one or two sections.

How impact damage spreads through a sectional door
A sectional door moves as a hinged stack of panels, so damage to one section loads the rest on each trip.
- Hinge failure
A folded section pulls at the hinges above it until they split.
- Track pinch
Bent track squeezes the rollers, so the door jerks through each trip.
- Spring overload
A door that binds loads the springs and the operator past their range.
- Falling door
A section that leaves the track can drop the door into the opening.
- Lost dock position
A dock door out of service backs freight up at the other bays.
Property type
Standard, high-lift and vertical-lift track
Repair scope
What commercial sectional repair covers
Sectional repair restores the damaged sections and track, then protects the opening from the next hit.
- Sections matched
Struck sections change for new ones of the same thickness and window layout.
- Track realigned
Bent vertical or horizontal track trued and anchored back in line.
- Hinges and rollers
Graduated hinges and fresh rollers put the sections back on a true line.
- Track guards
Heavy guards along the lower track absorb glancing contact from a lift truck before the track does.
- Dock bumpers and bollards
Bumpers on the dock wall and bollards beside the opening hold a trailer back from the door.
- Balance reset
Spring tension set for the new weight of the door once the sections change.

Local detail
Dock and bay doors in Carrollton
Your Carrollton distribution building may run several sectional doors along one dock wall. Keeping each one level and protected keeps freight moving through every bay.
Triage order
Why a struck sectional door needs the call now
A struck section keeps pulling at its hinges and bent track keeps pinching rollers, so one hit turns into a door off its track if the bay stays in use.
Calling while the damage sits in one or two sections keeps the repair to those sections and the track beside them. Call from a Carrollton loading dock or a Dallas County freight terminal while trucks can still use your other doors.

Common questions
Commercial sectional repair in Carrollton: dock-door points
Can one struck section change without a new door?
Usually, when matching sections of the same thickness and layout are still made. Several struck sections may call for a whole door.
Do track guards prevent lift-truck damage?
They take the hit that would bend the lower track, so a glancing blow stays on the guard instead of the door.
Should I run a door that has left its rollers?
No. A section out of the track can fall. Keep the door where it is and the bay empty.
A door held by a broken spring is a door waiting to drop.
Call from Carrollton before a broken spring or cable strips the opener or bends the sections.
