New Construction Drywall Schedule: A Sub's Timeline

Drywall sits at the choke point of a residential schedule. Every trade before it has to be done, and every finish trade after it is waiting on us. When a builder calls asking why a house is behind, the answer is usually found in the week before we were supposed to start, not in anything that happened once board was on the walls. Here is how we schedule drywall on new construction, and what we need from the GC to hit the dates.

Before a single sheet gets stocked, the house needs to pass its four-way rough inspection: framing, electrical, plumbing, and mechanical. In our market that also means the insulation inspection is signed off, since batts and any required draft stopping get covered the moment we hang. An inspection correction on rough electrical the day before our stock date is the most common two-to-four day slip we see, and it is entirely upstream of us.

Beyond inspections, the building needs to be dried in with windows and exterior doors set, and the slab and framing need to be at reasonable moisture. Hanging board in a house that is still drying out invites nail pops and joint problems six months later. In the St. George summer that is rarely an issue; a wet spring in Cedar City is another story.

Two more items belong on the pre-drywall checklist and get missed constantly: backing and low-voltage. Blocking for cabinets, grab bars, handrails, and TV mounts has to be in the walls before we close them, and so does every speaker wire, network run, and security rough-in. Opening finished drywall to add a missed backer costs the schedule far more than the backer ever would have.

Stocking comes first and takes about a day on a typical single-family house. Board gets delivered by boom truck and placed by room, laid out so the hangers are not carrying twelve-foot sheets up a staircase. Good stocking is invisible on the schedule; bad stocking taxes every day of the hang.

Hanging a typical production house runs two to four days with a full crew, longer for a large custom with high ceilings, barrel arches, or a lot of detail framing. This is the fast, loud part of the job. When a GC watches board fly onto the walls it is tempting to think the phase is nearly over, but hanging is the short leg of drywall.

Taping and finishing is the long leg, and it is governed by drying time, not effort. Tape coat, then fill coat, then finish coat, and each has to dry before the next goes on. With conventional drying compounds that is typically five to seven working days for a standard house at Level 4. Setting-type compounds can compress specific spots, but you cannot rush a whole house of topping coat without buying back problems at point-up.

Dry desert air is the one place Southern Utah does us a favor, because coats that drag for days in humid climates turn around overnight here. Winter flips it: an unheated house in January dries slowly, so temporary heat is not optional if the schedule matters. The house needs to hold reasonable temperature and ventilation through finishing, and that is a GC-supplied condition, not a drywall option.

Sanding and point-up take another one to two days, and then the house is ready for prime. If the spec includes texture, add a day to spray and a drying day before primer. All in, a realistic drywall window on a typical production house is ten to fifteen working days from stock to texture-complete, and quoting anything much tighter than that should prompt questions about what is being skipped.

What actually slips a drywall schedule, in the order we see it: failed or late rough inspections, other trades still working in the space during hang, no temporary heat or power, late material or a changed board spec, and design changes after hang starts. Almost none of these are drywall problems. They are sequencing problems that land on the drywall dates because we are the phase where they surface.

What a sub owes the builder in return is crew reliability and honest dates. We schedule crews to the confirmed stock date, we tell you immediately if a prior house is running long, and we do not say yes to a date we cannot staff. A drywall sub that overbooks crews is the flip side of a GC that calls us in before the four-way is signed, and both cost the same thing: days.

The habit that keeps our builder schedules tight is a walkthrough about a week before stock. Superintendent and our foreman walk the house, check inspections, backing, low-voltage, doors, windows, and heat, and confirm the count and the spec, including which rooms carry Level 5 or special texture. Twenty minutes of walking beats a week of slippage.

We have been running drywall crews for builders across Washington and Iron counties since 2001, from St. George production tracts to customs in Ivins and Kanab. If you are a GC putting together a schedule and want drywall dates you can build the finish trades around, send us the plans and the target stock date and we will give you a window we can actually hold.
