Food Trucks Repair for West Covina

Serving window frames, hatches and awning hardware

The serving window is the part of a food truck that gets used hardest and looked at closest. It is a large cut in a side wall, which removes structure from exactly the panel that flexes most, and the frame around that cut carries the hatch, the gas struts and often an awning. After a few seasons of road vibration the opening racks slightly out of square. The hatch touches at one corner first, the seal stops compressing along the bottom edge, and the truck starts taking water and dust through the gap while it sits at a lunch stop.

We treat that as a structural problem rather than a hardware problem, because tightening a latch on a distorted opening only moves the leak. The opening gets measured across both diagonals, the frame corners get straightened or rebuilt with new stock welded into the wall framing, and the perimeter gets resealed to the skin before the hatch is refitted. Only then does hardware alignment mean anything. Hinges are rebushed or replaced, strut mounting plates get reinforced where the fastener has pulled through thin sheet, and struts are fitted so the hatch holds position at the angle you actually serve from.

Awning hardware fails on its own schedule. Roll out awnings from Girard and similar suppliers load the body at a small number of brackets, and on a smooth sided unit those brackets are frequently anchored into skin and adhesive instead of into a framing member. One gust on an open lot takes the whole assembly out and tears a strip of skin with it. We rebuild the mounting into real wall structure, spread the load with backing plates behind the skin, seal every fastener that pierces the exterior, and refinish so the repair does not read as a patch.

• Serving window opening measured across both diagonals before any hardware work
• Frame corners rebuilt into the wall framing, not shimmed behind the hatch
• Hinge bushings, strut plates and latch strikers reset to a squared opening
• Awning brackets relocated into structure with backing plates behind the skin
• Every new fastener through the exterior skin sealed and refinished

Roof penetrations: exhaust hood flashing, vent curbs and air conditioner bases

A food truck roof carries more holes than almost any vehicle we see. The exhaust hood stack, a make up air vent, a roof air conditioner from Dometic or Coleman, Maxxair or Fan Tastic vent fans and sometimes a condenser all pass through a thin roof skin. Each one is a joint between materials that expand at different rates through a San Gabriel Valley summer, and each one is a leak waiting for its sealant to age out. Owners usually discover the problem in the first real rain of the season, long after the damage started.

Water rarely appears where it enters. It tracks along the underside of the roof sheet, follows a framing member downhill, and shows up as a stain on an interior wall panel several feet away or as a soft spot in the ceiling above a prep counter. By the time it is visible the roof framing in that bay has usually taken on moisture and lost strength. We open the area, replace the wet core and framing members, rebuild the roof sheet, and reset the penetration on new curb structure rather than laying fresh sealant over an old joint.

Exhaust hood flashing deserves the most attention of the group. It sits at high temperature, it is normally the largest single opening in the roof, and grease finds its way into every seam around it. We rebuild the curb tall enough that water cannot stand against the joint, fit new flashing, and finish it with a coating that tolerates heat and the cleaning chemicals used around a hood. The hood assembly itself, the fan, the ductwork and the fire suppression system belong to the supplier who installs and certifies them.

• Wet roof core and framing replaced before any new penetration is set
• Curb height rebuilt so standing water cannot sit against the joint
• Air conditioner base gaskets and vent flanges reset on sound roof structure
• Hood flashing rebuilt and coated for heat and cleaning chemical exposure
• Interior ceiling and wall panel repaired after the leak path is closed

Generator bay structure, propane compartment integrity and exhaust pass throughs

Generator bays live in the worst environment on the truck. An Onan or Cummins unit vibrates continuously while the kitchen runs, the bay floor collects road water and spilled fluid, and the slide out tray or mount frame is usually welded into a body section that was never designed for a fatigue load. Cracks start at the mount weld toe and at the corner of the bay opening. Once the bay floor loses section, the whole assembly begins to move, which accelerates everything else. We rebuild the bay floor, the mount structure and the door frame with correctly sized material and proper gusseting.

The exhaust pass through is its own repair. It penetrates a body panel at high temperature with a component that moves relative to the body, so a rigid, sealed joint eventually cracks or burns through the surrounding material. We rebuild the pass through with a heat tolerant sleeve, restore the panel around it, add shielding where the routing runs close to combustible structure, and seal the joint so exhaust cannot enter the bay or the interior. What we do not do is open the generator: internals, fuel systems, control boards and load testing all stay with your generator service provider.

Propane compartments follow a different set of rules and we build them to respect that. The compartment has to stay isolated from the kitchen interior and vented low to the outside, so the repair centers on the shell, the floor vents, the door frame and the sealing at every wall the compartment shares with the occupied space. We replace corroded floor pans, clear and rebuild vent openings, straighten door frames so the door closes flush, and reseal the interior wall. Regulators, hoses, valves and cylinder certification stay with your propane supplier.

Equipment mounting into the floor framing, not into the plywood

The most common structural complaint we hear from West Covina food truck operators is that the equipment moves. A griddle creeps forward, a fryer rocks when the truck brakes, a refrigerator drifts sideways on the drive to a stop and the drain line pulls tight. In almost every case the cause is the same: the equipment was fastened into the plywood subfloor alone. Plywood holds a screw well the first month and poorly after a thousand heat cycles and a few hundred washdowns, and once the fastener wallows its hole the movement compounds.

The correct repair locates the actual floor framing, which on most kitchen bodies is a steel or aluminum crossmember grid under the subfloor. We add crossmembers where the equipment position does not line up with existing structure, install backing plates under the floor, and through bolt with load spread instead of relying on a fastener biting into wood. Every penetration that goes through the floor gets sealed from below so the mounting itself does not become the path for water and grease into the framing.

The same logic applies above the floor. Wall mounted shelving, hood support brackets, exhaust fan mounts and beverage equipment all want a framing member behind them, not a sheet of FRP panel. We open the wall where needed, add blocking or steel between the studs, close the wall with new panel and coving, and seal the joint. Plumbing connections, gas lines, appliance electrical hookups and the appliances themselves are handled by your equipment installer. We build and finish what they mount to.

• Equipment loads carried by floor crossmembers and backing plates, not subfloor plywood
• New crossmembers fabricated where the layout does not match existing framing
• Floor penetrations sealed from below after every through bolt
• Wall blocking added behind shelving, hood brackets and fan mounts
• Gas, water and appliance electrical connections stay with your equipment installer

Interior sanitation surfaces, washdown floors and tank mounting structure

Interior surfaces in a kitchen body have to survive daily washdown and read clean to an inspector, which means the repair standard is different from a normal interior job. FRP wall panels are set with continuous adhesive and the seams are covered with proper trim rather than caulked over, stainless is used where an inspector expects a wipeable surface next to a cook line, and inside corners are coved so there is no square joint holding residue. We rebuild damaged panel sections, replace trim, and finish corners the way the surface is going to be cleaned.

Floors take the worst of it. A kitchen floor covering has to run up the wall as a coved base, and the coved base has to be bonded to a sound substrate or it lifts and traps water behind it. When we open a soft floor we usually find the subfloor wet under the covering at the step well, along the wall behind the sink, and around any fastener that went through unsealed. Repair means replacing the subfloor section and framing, then reinstalling covering with sealed seams and a continuous coved base up the wall.

Fresh and waste tank mounting is a structural item hiding under a plumbing item. A full tank is a heavy, sloshing mass hanging on straps, and the straps load whatever they are bolted to. Where they are bolted into a floor sheet or a thin body member, the fastener eventually elongates its hole and the tank starts to swing. We rebuild the mounting into framing, replace straps and cradle structure, and add support so the load spreads. Tanks, pumps, water heaters and the plumbing between them stay with your plumbing supplier.

Body shell repair, wraps and getting a food truck to Yorba Linda from West Covina

Outside the kitchen, a food truck collects the same damage every working commercial vehicle does. Low clearance strikes at parking structures and drive throughs crush the front roof edge and the hood stack. Step van rockers pick up curb rash from years of parking tight to a sidewalk. Rear door frames and step wells distort from constant loading. On FRP bodies the classic failure is delamination, which reads as a soft bubble under the wrap where the skin has separated from the core, usually starting at a fastener or an old repair.

Graphics decide how the truck sells, so we plan the substrate for them. A riveted body will always show its rivet line through vinyl, and pretending otherwise produces a wrap that looks poor within a month. Where the customer wants a smooth read, that has to be built in with panel and filler work before paint and vinyl. On a smooth sided body the substrate needs to be flat, fully cured and clean, because vinyl over fresh finish that has not gassed out will lift at the edges. We coordinate with your wrap installer on timing so that does not happen.

Every job is performed in shop at Yorba Linda. We do not offer mobile service and we do not travel to a commissary or an event lot. Plan on about 22 miles and 30 to 45 minutes from West Covina: the 10 or the 60 west to the 57 south, then the 91 east to Imperial Highway, with Carbon Canyon Road to the 71 as the alternate when the 57 stacks up through Brea. Shop hours are Monday through Friday 8:00 AM to 5:00 PM and Saturday 9:30 AM to 3:00 PM. Call (949) 799-3387 to schedule, and bring the truck empty of product if the interior is part of the job.

• Low clearance strike damage to the front roof edge and stack repaired as structure
• Step van rocker and rear door frame rebuilt rather than filled
• FRP delamination cut back to sound laminate and rebonded under clamp pressure
• Substrate prepared and cured before vinyl so graphics do not lift at the edges
• All work performed in shop at Yorba Linda, never at a commissary or event lot
