Posted rates at https://ocrv.biz/prices/ ## How is your box body built, and why does that matter? Two construction types dominate, and they repair completely differently. **Sheet and post**: Aluminium sheet riveted to vertical posts, with a scuff band inside. Damage is contained to the panels between posts, so a struck section can be cut out and replaced without disturbing the rest of the wall. Rivet lines are the leak points, and a strike that loosens rivets over several bays lets water track inside. **Fiberglass reinforced plywood**: A smooth one piece side with the structure bonded in. Better aerodynamics and a clean surface for graphics, but damage is not contained: an impact delaminates the panel from the substrate over an area well beyond the visible dent, and the repair means bonding rather than riveting. Insulated and refrigerated bodies add an interior liner and foam core, where impact damage lets moisture into the insulation and the box slowly loses efficiency. Reefer and insulated box skin and liner repair runs $1,000 to $18,000 and 8 to 80 labor hours. See the [posted rate card](/prices/). ## Why does the back of the box always go first? Because that is where the dock is, where the water collects and where the load moves. Four specific failures account for most of the work: - **Rear sill and threshold corrosion.** Water runs off the roof, down the rear frame and sits on the sill. Add pallet jack wheels crossing it thousands of times and the sill is the first structural component to fail on most bodies. - **Corner post damage.** Backing to a dock at a slight angle puts the whole impact into one corner casting. The dent is cosmetic; the post behind it is structural. - **Roll up door problems.** Slats bent by a strike, a torsion spring that has lost tension, seized rollers, worn track, or a bottom seal that no longer contacts the sill. - **Header and top rail strikes.** Low clearance at a canopy or a parking structure, which bends the header and misaligns the door track above it. Roll up and swing door service runs $400 to $4,500 and 2 to 18 labor hours; cargo door, ramp door and roll up door service runs $400 to $5,500. ## What does a soft box floor mean? That water has been reaching the underside, usually for longer than the operator realises. Box floors are typically laminated hardwood over steel crossmembers, and they fail from the bottom up because that is where the moisture is. By the time a floor feels soft underfoot, the boards have delaminated and the crossmembers underneath usually need inspection for corrosion. The entry points are predictable: the rear sill joint, a rivet line low on the side wall, a wheel well seam, or a puncture from something dropped inside. Repairs range from replacing a section of decking to a full floor replacement, and cargo floor and liner installation runs $400 to $4,500. On trailers, floor repair and replacement in wood, aluminium or steel deck runs $500 to $9,500. Two habits keep floors alive. Sweep out standing water rather than letting it find the seams, and repair a puncture the week it happens rather than the quarter it happens, because every wet cycle spreads the delamination outward from the hole. ## What else gets addressed while a box truck is in the shop? Everything that would otherwise become a second visit, since downtime costs more than labor on a working truck. The usual add ons: - **Liftgate.** Platform, hinges, hydraulics and the electrical feed. Liftgate install and repair runs $1,500 to $8,500 and 8 to 35 labor hours. - **Translucent roof panel.** The light panel that makes the box usable without work lights goes brittle and cracks with age, and a cracked one is a leak directly onto the load. - **Interior tie downs.** E track, D ring and tie down installation at $250 to $2,500, with correct backing behind each anchor. - **Reflective conspicuity marking.** $250 to $1,200, and worth reapplying whenever a panel is replaced. - **Graphics.** Decals at $500 to $5,500 or a vinyl wrap at $1,500 to $9,500, since a repaired panel without livery looks worse than the damage did.

Both are common. Individual slats can be replaced when the damage is contained and the track is straight. What forces a full door replacement is a bent header or track that has distorted the opening, since a new door in a twisted opening binds immediately. The opening gets measured before any door decision is made. ### Is it worth repairing an older box or should it be replaced? It depends on the floor and the rear frame rather than on the skin. Panels and doors are straightforward to renew. A rotted floor combined with a corroded rear sill and soft crossmembers is where the arithmetic turns toward a replacement body, and that is a conversation worth having at the estimate rather than mid repair. ### Do you repair refrigerated bodies? Yes, on the body side: skin, liner, insulation and door seals. Reefer and insulated box skin and liner repair runs $1,000 to $18,000. What matters most on these is sealing the repair properly, because moisture in the foam core reduces efficiency permanently and no amount of unit capacity compensates for a waterlogged panel. ### How quickly can a box truck be turned around? Panel and door work is often within the week when parts are on hand. Structural repair at the rear frame, floor replacement and liftgate work run longer. Sending photographs and the vehicle details before the truck arrives lets parts ordering start early, which is usually the difference between a week and three. ## Related - [Commercial and Heavy Vehicles](https://ocrv.biz/vehicles/commercial-heavy/) - [Box Trucks](https://ocrv.biz/vehicles/commercial-heavy/box-truck-repair/) - [Truck Repair](https://ocrv.biz/truck-repair/) - [Fleet Repair](https://ocrv.biz/fleet-repair/) - [Custom Fabrication](https://ocrv.biz/services/custom-fabrication/) - [Prices and Posted Rates](https://ocrv.biz/prices/)
