Our Company

On-Site Fleet Service, Inc. has been in business since 1978 and grown into the largest non-dealership professional diesel and school bus repair provider in the state of New Jersey.

We are a second-generation family-owned and operated repair company originally founded as a mobile fleet service. Over the years, On-Site evolved to include four repair facilities throughout NJ. While we do still perform occasional “on-site” repairs, our customers now prefer to visit our state-of-the-art locations. We choose to retain the name On-Site as a nod to our proud history and longstanding reputation.

Stop by any of our professional shops.

  • East Brunswick
  • Rutherford
  • Kenilworth
  • Lakewood

On-Site offers a complete menu of maintenance programs for school buses, medium-duty trucks and heavy-duty trucks, including computerized preventive maintenance, brakes, clutches, engines, transmission rebuilding, and road service. We can also offer the individual truck owner the type of service and attention that a large fleet would receive.

With the capability of tracking DOT Inspections, PM Services and Opacity testing in our computer systems, we can help control both large and small fleets.
