Trailer Repair Without Hauling It to a Shop

A trailer with a bad light, a dragging brake or a door that won’t latch can’t go out with a load. Getting it to a shop means pulling a tractor and a driver off the road, burning hours of service and waiting for an open bay — sometimes for a five-minute fix.

Steelcore’s mobile trailer repair comes to the trailer instead: your drop yard, a terminal, a customer’s dock, a truck stop or the shoulder of I-85. We find the problem and, in most cases, fix it right there, so the trailer is ready to hook again.

We handle semi trailer repair for owner-operators and fleets across Charlotte and about 200 miles around it — from trailer brake repair and air leaks to trailer light repair, doors, landing gear and welding. Got a yard full of trailers? We can work through them in one visit.

Trailer Service for Fleets and Drop Yards

Yard Service for Fleets

  • One visit, many trailers: send us the list and we work through it at your drop yard, terminal or customer lot.
  • The trailer stays put: no tractor, no driver and no shop queue until it's ready to roll.
  • Unit-by-unit notes: you see what we found and fixed on each trailer, by unit number.
  • Scheduled or same day: set a regular yard day, or call when a trailer goes down.

DOT Prep & Trailer PM

  • Before an inspection: we check and fix lights, brakes, air leaks, tires, mud flaps and doors.
  • After an out-of-service write-up: we repair the items on the report so the trailer can roll again.
  • Preventive maintenance: brakes and slack adjusters, hubs and bearings, tires, lights, the air system, suspension and landing gear.
  • Fewer surprises: small problems get fixed at the yard before they turn into a roadside breakdown.

Truck down too? We fix the tractor and the trailer in the same visit — see mobile truck repair.

Broken down on the highway right now? Call (704) 441-3909 or see our 24/7 emergency roadside repair.

Tractors due for PM? We service them in the same yard visit as your trailers — see mobile truck maintenance and PM.

How Mobile Trailer Repair Works

  1. Send the Details

    Call or text where the trailer is — yard address, dock number or exit — plus the unit number and what's wrong. Several trailers? Send the whole list. Photos help.

  2. We Come to the Trailer

    A mechanic heads to your yard, dock or roadside spot with the tools and common parts. Urgent calls get a real ETA on the phone; yard work can be scheduled around your dispatch.

  3. Ready to Hook

    We fix each trailer, tell you what it needs and what it will cost before we start, and leave you a list of what was done on each unit.

Mobile Trailer Repair FAQ

Yes. We work at drop yards, terminals, warehouses, customer docks, truck stops and on the roadside — wherever we can safely work around the trailer. If the site needs a gate pass or an on-site contact, just tell us when you call.

Dry vans, reefer trailers and flatbeds. On reefers, we repair the trailer itself — brakes, lights, doors, suspension and air lines — not the refrigeration unit.

Yes. We go trailer by trailer, check the items inspectors look at most — lights, brakes, air leaks, tires, mud flaps and doors — and fix what we find, so your trailers are ready before an inspection, not after a write-up.

Yes. We can set up preventive maintenance at your yard on a regular schedule — brakes and slack adjusters, hubs and bearings, tires, lights, the air system, suspension and landing gear — so trailers stay on the road between inspections.

In most cases, yes. Lights, brakes, air leaks and tires are among the most common out-of-service items, and we fix them where the trailer is parked. If a part has to be ordered, we tell you right away and plan the return visit.

It depends on the repair and the parts it needs. We charge a service call fee plus labor and parts, and several trailers in one visit share one service call. We tell you the cost before we start the work, so there are no surprises on the invoice.

We accept Comdata, EFS and T-Chek fleet cards, major credit cards and Zelle. Net terms are available for qualified fleets.

Yes. We’re available 24/7, and yard work can be scheduled for nights or weekends, when your trailers are sitting anyway.

Yes. We fix tractors and trailers, so one call covers both. See mobile truck repair.
