How We Work

From Phone Call To Invoice.

The same four steps every time. No dealership runaround, no surprise charges, no parts-swapping.

  1. Phone Dispatch

    Call dispatch with machine info, symptoms, and location. We confirm an honest ETA and a starting estimate before the truck rolls.

  2. On-Site Diagnostic

    Truck arrives stocked with diagnostics, tools, fluids, and common parts. We run a clean diagnostic and define a clear scope.

  3. Real-Time Quote

    Cost conversation happens before parts work starts. No surprise charges, no upsells, no parts-swapping.

  4. Itemized Invoice

    Labor, travel, and parts billed line-by-line. Net 30 terms available for fleet accounts.

By The Numbers

Mobile, Insured, Mine Site Ready.
