We build casework rather than order it.

Casework, millwork, and why the distinction matters

The words get used loosely and the difference is worth holding onto, because it changes who should build a thing and where.

Casework is boxes: cabinets, base and wall units, counters, storage. It is modular by nature, and much of it can be bought as a standard product if the openings cooperate.

Millwork is everything shaped to the building: trim, paneling, reception desks, feature walls, non-standard openings, anything cut to a dimension that exists only on this job.

The California license treats them together. The C-6 classification covers a contractor who makes cabinets, cases, sashes, doors, trims, nonbearing partitions and other items of finish carpentry by cutting, surfacing, joining, gluing and fabricating wood, and who installs and completes that work in buildings. The fabrication and the installation sit in the same classification, which is a fair reflection of how the work actually goes.

The case for building instead of ordering

We do not build everything. Where a standard product fits the opening and the schedule, buying it is cheaper and we will say so.

Three situations change the answer. The first is a non-standard opening, where a catalog unit means filler strips, scribes and a result that reads as approximate. The second is lead time. A custom order carrying twelve weeks is a schedule problem long before it is a cost problem, and a shop that can start Monday is worth a premium that looks irrational on a line-item comparison. The third is a thing nobody makes, which is most of what comes to our router.

The quiet fourth reason is accountability. When the shop and the field crew are the same company, a piece that does not fit gets modified that afternoon. When they are different companies, it becomes a claim.

Material selection in labs and clean areas

This is the question we get asked most on pharmaceutical and biotech work, and the honest answer is that it depends on what will be done to the surface rather than on which material is best.

Stainless steel is non-porous, takes aggressive cleaning and sterilization, does not absorb anything, and is the expected answer where contamination control governs. It is also the most expensive, it dents, and it shows every mark.

Phenolic resin handles moisture and most chemicals well, is lighter and more economical than stainless, and suits wet labs where the chemistry is ordinary rather than extreme.

Epoxy resin is the usual answer for work surfaces specifically, where heat and chemical resistance at the bench matter more than anything else.

Wood-based casework, however well finished, is generally inappropriate in a controlled environment because the substrate can absorb moisture at any edge or penetration that is ever damaged.

There is also a detail that gets missed until late: in a clean area the junction between casework and wall has to be sealed and cleanable. A beautiful cabinet with an uncleanable gap behind it has failed at the only thing the room is for.

Shop built against field built

Shop work is better work. The equipment is better, the conditions are controlled, the dust stays in our building rather than in your occupied one, and the tolerances are tighter because the tools holding them are not a cordless saw on a bucket.

What shop work demands in exchange is accurate field dimensions, which is why we measure rather than scale drawings, and it demands that the piece can physically get to where it is going. A reception desk that will not turn the corner out of the freight elevator is a problem of exactly one kind, and it is solved at the drawing stage by deciding where the joints go.

Field work earns its place in the trim, scribes and transitions, where a building is never quite what the drawing said. The craft is in knowing which parts belong on which side of that line before anything is cut.
