Enterprise fleet maintenance, mobile service and step-van rentals.
Sigma Fleet Services gives large commercial fleets one accountable partner for maintenance coordination, regional repair execution, mobile service, inspections, and replacement capacity.
Enterprise governance without sacrificing field responsiveness.
Standardize intake, authorization, escalation, maintenance expectations, and performance review while service remains aligned to the realities of each operating market.
One partner for fleet uptime.
Sigma brings repair, replacement vehicles, planned maintenance, and operating support together so fleet managers have fewer vendors and clearer accountability.
We bring the shop to your fleet.
Reduce unnecessary downtime and vehicle movement with scheduled maintenance and repair performed where your fleet operates.
Truck down? We can repair it—and help keep the route covered while it’s in service.
Replacement vehicles when downtime isn’t an option.
Transit vans and commercial step vans for temporary replacement, peak demand, and supplemental fleet capacity.
Submit dates, vehicle class, and operating location. We will confirm the appropriate unit and availability.
From reactive repairs to managed uptime.
Build a maintenance program around vehicle type, duty cycle, service intervals, and operating needs rather than waiting for the next breakdown.
