Mobile Offices and Workshops Repair For Lake Forest Owners

Workshop benches bolted through a body side that carries the load alone

A workbench in a van build is used the way a bench in a building is used, which means somebody eventually leans on it, clamps something to it and works a hammer against it. In a building the bench is anchored to a wall with studs behind it. In a van it is often anchored to a body side that is a single sheet of thin metal with a rib every so often. The load goes in at four bolts and the panel takes all of it. What appears from outside is a shallow dimple over each fastener, then a split, then a tear that runs with the panel. The repair is a panel repair plus a redesign of the attachment, spreading the load across a fabricated backing frame that reaches the body ribs rather than concentrating it at four points.

Slide-out office rooms on a chassis that flexes at every driveway

Some field office builds borrow a slide room from the recreational world to create a wider working space when parked. That mechanism was engineered for a coach or a trailer frame with known deflection characteristics, and dropping it into a box body or a commercial chassis changes the picture. The chassis twists differently, the opening moves relative to the room, and the seals that depend on a consistent gap stop sealing consistently. Symptoms are a room that binds partway, uneven seal compression, and water at the lower corners. We square the opening, correct the mechanism alignment, rebuild the seal package to the actual gap, and where the chassis flex is the underlying cause we reinforce the opening so the geometry stops moving.

Compressor and welder mounting that cracks the deck it sits on

Trade workshop builds routinely carry an air compressor, a welder or a generator bolted to the floor or to a deck at the rear. These devices are heavy, they run at a frequency the mounting was never tuned for, and their center of mass sits well above the fasteners. The result is a slow fatigue failure that starts as a hairline at the corner of a mounting plate and finishes as a cracked deck section with a piece of equipment moving around on it. Isolation mounts help and are frequently omitted. When we repair one of these we rebuild the deck section, fabricate a mounting plate sized for the load, add isolation where the equipment tolerates it, and tie the assembly into a structural member rather than into sheet.

Cable pass-throughs that turn a roof into a set of unsealed holes

Field offices accumulate roof penetrations faster than any other vehicle in this category: a cellular antenna, a GPS puck, a radio whip, a data cable, a vent, sometimes a small satellite dish. Each was added on a different day by a different installer, and the common technique is a hole, a grommet and a generous bead of sealant on top. Southern California sun destroys a surface bead within a few seasons. Water then enters and travels along the roof structure to a low point that may be nowhere near the hole, which is why the leak gets misdiagnosed as a window. We strip the penetrations back to clean substrate, install proper glands with mechanical fastening and a bedded seal, and consolidate the runs where several holes can honestly become one.
