We’re Big on
Performance. With
Big-Time Capabilities.
Heavy-duty trucks – especially diesel engines – are in a class by themselves. Proper maintenance and repair require years of training, and down-in-the-trenches know-how and experience – exactly what FleetMasters provides.
With two New England locations (Windsor Locks, CT and Lawrence, MA) we service hundreds of heavy- and medium-duty trucks every year — most makes and models. We maintain and repair trailers, too. With specialty equipment on hand, we tackle problems large and small to get you back on the road with minimum down time and lost productivity.

We Train, and Train
Some More, to Be the Best.
With vehicle technology rapidly and constantly evolving, our experienced mechanics are continually updating their knowledge and skills for faster turnaround and more dependable results. With all the right tools – including lifts capable of hoisting more than 60,000 pounds, and OEM diagnostic tools for communicating with almost every model of truck and engine – we can do more than meet your expectations. We work hard to exceed them. And that goes for the latest plus older model trucks alike.
Whether it’s tracing electrical faults, “Check Engine” light diagnostics, repairing suspension components, or fixing oil leaks, we have the skill and experience to get your truck fixed promptly and efficiently.

Fleet Truck Maintenance | Fleet Truck Repair
Our preventive maintenance services can be scheduled to best suit your company’s operations. Maintenance services include oil changes, tire rotations, brake inspections, engine diagnostics, and more. Our experienced technicians use advanced tools and technology to detect potential issues before they become major problems, helping to keep your trucks on the road and out of the shop.
To maximize uptime, we also provide on-site inspections that can be scheduled at weekly, bi-weekly, or monthly intervals.
At the same time, mechanical failures are bound to happen, and yet they don’t always occur during regular business hours. That’s why our team is available to provide emergency repair services, both roadside and in-shop, to help minimize disruptions to your business operations.
