Mobile Fire Truck Repair. We Come to the Station — Day or Night.
On-site diagnostics, repairs, and maintenance for fire apparatus across eastern PA, northern NJ, southern NY, and northern MD. Your truck doesn't move until it's fixed.
Taking a fire truck out of service to haul it to a dealership two states away costs you more than time — it costs response coverage. Our mobile units carry the diagnostic gear, hand tools, hoses, fittings, fluids, and common consumables to handle most repairs in your apparatus bay. When a heavier rebuild is needed, we plan it around your call coverage, not the other way around.
Bring the shop to the apparatus.
Hauling a fire truck to a dealer shop is a planning event. You arrange a tow or shuttle the rig under its own power, you negotiate a calendar window, you sit in a queue behind two weeks of other work. Then you do the round trip back. Mobile repair removes most of that. We bring the gear, the diagnostic tools, the consumables, and the experience to your station. The rig stays in your district.
What gets done on-site.
More than people expect. Pump packing, valve seal kits, primer service, relief valve adjustment, transfer valve work. Engine diagnostics, fuel filters, DEF system service, regen forces, sensor replacement, charge air work. Multiplex troubleshooting — Class1, Weldon V-MUX, Innovative Controls. Brake system work, air dryer service, slack adjusters. Hydraulic hoses fabricated on the spot. Aerial outrigger, slide, and rotation service. Battery, alternator, and scene-lighting work.
What still goes to a shop.
In-frame engine rebuilds. Structural aerial welding and NDT-required work. Cab refurbishment. Anything that genuinely needs lift access, a clean environment, or a controlled rebuild bay. We tell you before we start whether the job is in-bay or shop scope, and we coordinate the shop work with a partner facility when needed.

Recent Fire Truck Repairs.
A representative slice of recent on-site work — the kind of failures that take an apparatus out of service and the kind of fixes that put it back in. Pump packing, DEF system faults, aerial hydraulics, multiplex electrical, brakes, charging systems, and everything in between.
