When to install
closets during
a renovation.

Ask when to install closets during a renovation and most answers stop at installation day: empty the room, paint first, keep the pets out. On a real project the more useful question is when each closet decision has to be made, because the cabinetry goes in near the end but depends on work that is buried in the walls months earlier.

The short answer: custom closets are installed after the finished floor is down and the walls are primed and painted, and before the final paint touch-up and any carpet. They are measured once the walls are closed and finished, and they must be designed before drywall, so the blocking and electrical rough-in are where the cabinetry needs them.

That gives a fitted closet four hold points in the schedule rather than one. Miss the first and you are opening finished walls. Miss the second and the shop is building to numbers that will not match the room. The rest of this note walks through each one from the maker's side, for designers, architects and general contractors sequencing a gut or partial renovation.

The millwork hold points, at a glance.

Before the walls close: blocking and electrical rough-in.

Closet cabinetry is heavy once it is full. A hanging bay loaded with coats, a wall of shelves holding books or folded denim, upper cabinets with luggage: all of that is carried by the wall, and drywall anchors are the wrong thing to trust with it. The answer is solid backing, typically a continuous band of plywood or lumber between the studs at the heights where the cabinetry fixes to the wall. In New York apartments with metal-stud partitions this matters even more, because a light-gauge stud on its own is not much to screw into.

The blocking does not need to be precise to the inch, but it needs to exist across the full run and over the height band the drawings call for. Generous is cheap at framing and expensive afterward. Photograph it with a tape in the frame before the board goes up; those photographs save a lot of guessing on installation day.

Electrical is the other buried decision. Integrated closet lighting usually means a low-voltage LED system with a driver that has to live somewhere accessible and ventilated, a switch or door-activated contact, and wire paths that arrive exactly where a cabinet side or top will receive them. Add any outlet inside the cabinetry — a valet drawer with charging, a steamer cupboard, a vanity mirror — and the box location has to come from the closet drawings, not from a standard height. A receptacle that lands behind a drawer box or a fixed shelf is the most common rough-in mistake we see. While the walls are open, check that no supply register, return or thermostat sits where cabinetry will cover it.

This is why the closet should be designed before demolition is finished, not after the walls are painted. The design does not have to be fully detailed, but the run lengths, heights, lighting scheme and any powered features must be fixed enough to mark up a framing and electrical plan.

When should custom closets be measured?

Measure once the walls are closed, taped and finished, and the room is as it will be — not from the framing, and not from the architectural plans. Board, skim coat and corner bead all change the numbers, and an old wall that has been furred out to straighten it can move a quarter of an inch or more from the drawing. Our survey of the room records final dimensions, out-of-plumb and out-of-level readings, ceiling height at several points and the as-built positions of outlets, switches and lighting feeds. Every scribe and filler in the drawings is sized from that visit.

If the schedule is tight, we can draw and price from the plans earlier and hold the shop drawings for the survey. That keeps the design moving without committing material to dimensions that have not been built yet.

Drawings and milling run while other trades work.

Lead time on custom millwork starts when the drawings are approved, not when the room is measured or the deposit is paid. That is the real reason to measure early in the finishes phase: the shop drawing review and the milling can then run while the painter and flooring installer are working, instead of after them. On our published schedules, measured from approved drawings, a reach-in takes about two to three weeks to installation, a typical dressing room about four to six weeks, and a whole residence drawn as one set about ten to sixteen weeks, phased around the household. How long a custom closet takes covers what moves those ranges.

In practice: survey as soon as the walls are finished, turn the drawings around quickly, and schedule installation for the week the floors are done. Late changes are the thing that breaks this. Once a cabinet is cut, moving a partition or a light switch is no longer a drawing revision.

Should closets be installed before or after flooring?

After, in almost every case with hard flooring. Install the closet on the finished floor and the floor runs continuously under it, so the room can be refinished or the cabinetry replaced decades from now without a patch in the wood. The cabinet base is levelled and scribed to the finished surface, so the toe kick sits tight to the floor with no shimmed gap at the low corner. The finished floor height also sets the drawer and hanging heights; build to the subfloor and every dimension shifts by the thickness of the floor.

Two qualifications. First, with a floating floor — engineered planks or laminate on an underlayment — heavy fixed cabinetry can pin the floor and stop it moving; follow the flooring manufacturer's guidance, which sometimes means stopping the floor at the cabinet line and covering the edge with the toe kick. Second, carpet goes in after the closet: the installer runs the carpet to the toe kick and tucks it, which is cleaner than cabinetry crushing a pad.

Finished floors need protecting once they are down. Plan for heavy floor protection to stay in place through installation, and make sure any site-finished floor has fully cured before cabinetry is set on it.

Paint, baseboards and the last coat.

Paint the walls inside the closet before installation, primer and finish coats both: nobody can reach behind a cabinet afterward. Leave the final touch-up of the room until the closet is in, because installation always leaves a scuff or two. Give the paint several days to cure before cabinetry is pressed against it.

Baseboard is a coordination point that is easy to miss. Where cabinetry runs floor to ceiling, there should be no baseboard behind it; tell the trim carpenter which walls to skip, or the installer will be removing new trim. Where a closet meets a run of baseboard, the drawings should say how the two meet — the base dying into the cabinet side, or a toe kick detailed to match the base profile. Crown and ceiling scribes work the same way.

The room also needs to be stable. Solid wood and veneered panels move with humidity, so cabinetry should go into a space where plaster, tile grout and floor finishes have dried and the heating or air conditioning is running, not into a damp shell.

How the schedule changes in a partial renovation or a co-op.

In a partial renovation, where the closet walls are not being opened, the hold points collapse. There is no rough-in window, so the design works with existing outlets and runs lighting surface-mounted or through the cabinetry, and we confirm the wall construction during the survey to choose the right fixings. The closet can then go in whenever the floors and paint in that room are finished.

In co-ops and condos, the building adds its own constraints: alteration agreements, permitted work hours, insurance certificates, freight elevator bookings and sometimes a summer work window. Those affect the installation date more than the shop does, so they belong on the schedule at the start. Our co-op and condo installation guide lists the questions to settle with the managing agent before fabrication.

How we fit into a trade project.

On trade projects we start with a free project consultation and a personalized 3D design, at the site or at the Bronx workshop. CAD and Revit resources are available on request so the closet can be dropped into your set early enough to mark up blocking and electrical. You get a written scope and quote, a named project contact, and a finish sample box when finishes are being chosen, with costs confirmed before ordering. The design, milling and installation all come from our own workshop and crew, so the person who surveys the walls is working with the people who build and install to them.
