Fire Truck Repair Built Around Real-World Demands in & Around Janesville, WI
Fire trucks experience long idle times, high electrical loads, frequent braking, and constant weight stress. Over time, those conditions create wear that can’t be ignored. Fire truck repair focuses on identifying issues early and resolving them before they affect reliability or safety.
Common service needs include braking concerns, suspension and steering issues, electrical faults affecting lighting or auxiliary systems, cooling system problems, and drivability complaints. Preventive maintenance is equally important. Routine inspections, fluid services, and system checks help reduce unexpected downtime and keep equipment compliant with operational standards.
When a breakdown happens away from the station, mobile repair support helps limit delays. Everything is treated as roadside, allowing repairs to be performed where the vehicle sits whenever possible. With shop hours Monday through Friday from 7AM to Midnight and 24/7 roadside service available, support is accessible even when issues occur outside normal business hours.

One side of the shop is dedicated to trailers, while the other is reserved for trucks, helping minimize delays and congestion.
Accurate handling and tire wear matter for vehicles that respond at speed. The shop is equipped with the largest alignment pit in the state of Wisconsin, allowing precise alignment work when needed. Extensive industry certifications from CAT, Cummins, Volvo/Mack, Detroit Diesel, Wabco/Bendix/Meritor, Hunter, ASE for Heavy Truck, and Delco reflect a commitment to proper procedures and up-to-date training.
