Carol Stream, IL
Carol Stream’s industrial base runs along North Avenue and Route 59, with manufacturers and distributors shipping out of docks every day. We bring fleet preventive maintenance to your dock, so every shipment leaves on equipment that’s been inspected and serviced.
What we offer
Every off-site PM costs a driver’s time, a run down North Avenue or I-355, a tractor out of rotation and a trailer sitting idle at the dock. Servicing your fleet on-site gives all of those hours back to your operation.
Fleet PM-A, PM-B and PM-C on schedules that track themselves
Trailer PMs for doors, seals, floors and landing gear
Heavy duty truck repair for air brakes, electrical and cooling systems
Yard maintenance during off-shifts and weekends
Mobile diesel repair dispatched for breakdowns
DOT inspections and annual certification completed on-site
WHY CHOOSE US

Every inspection is documented with photos and video before you approve any work, and records sync with QuickBooks Online. Start with a complimentary 50-point yard safety audit, and you’ll receive a written proposal built around your fleet.
