Trailer Door Repair & Replacement in SC

When trailer doors fail, cargo is at risk

Roll-up, swing, and barn-style doors protect freight from weather and theft. Bent tracks, worn springs, leaking seals, or binding latches slow every stop—and can put drivers in awkward positions on the shoulder. KM Truck & Trailer repairs and replaces trailer doors so your equipment closes square, seals tight, and locks with confidence.

Door repair services we perform

We realign panels and tracks, service or replace rollers and cables on roll-up doors, repair hinges and cam arms on swing doors, and refresh seals and gaskets to stop water intrusion. Lock and latch work includes adjustment, repair, or replacement so your security matches the value of what you haul.

Frame damage from dock strikes or shifting freight can be addressed with welding and reinforcement when appropriate, restoring geometry so the door operates without fighting the opening every time.

Replacement doors and professional installation

If corrosion, impact damage, or repeated field repairs make replacement the smarter call, we help you select a door suited to your trailer type and freight. Installation includes alignment, seal seating, latch adjustment, and operational testing so you leave with smooth operation—not a rework job next week.

Mobile door service when you cannot come to us

Door problems often show up at a receiver, rest area, or yard—not at home base. Our mobile team brings tools and common hardware to many South Carolina locations so you can avoid an unnecessary tow when the fix is on-site.
