We offer Bi-Annual State Inspection for PA school buses!


School buses are an essential part of our world. They carry children to and from school, sporting events, and field trips. The safety of those children lies in the maintenance of the school buses.

Local school bus contractors can be confident that they will be ready for the school year with our School Bus Engine/Chassis Maintenance.

We make sure that your buses are checked over thoroughly, fluids and filters are changed, and all safety features are working properly.

Does your bus need repairs? No problem! Just give us a call!

We offer OnSpot tire chain installation and servicing! Ice and slush can make for very hazardous conditions, and when you hold young lives in your hands, having OnSpots deploy within seconds can make the difference!

We offer Half Services, which is a reduced version of our annual Engine/Chassis Maintenance and Inspection. These are an extra measure to ensure your buses stay safe during the school year!

We encourage Woolwax Undercoating for all school buses! Woolwax undercoating is a great preventative maintenance for all vehicles, and buses are especially important due to driving on many dirt roads and salted roadways. With annual application, the risk of rust and corrosion continuing, or even beginning, reduces greatly!

We would be more than happy to help you keep your buses running so you can keep those children safe!
