Confirm framing is complete, straight, and dry, and that any required inspections behind the board are signed off before you hang.
Check moisture in the space. Board hung into a damp building telegraphs problems through the finish for years.
Confirm backing is in place for cabinets, grab bars, towel bars, handrails, and wall mounted fixtures.
Stage sheets flat, off the floor, close to each room, in hanging order, so the crew is not carrying board all day.
Confirm ceiling strategy first: ceilings before walls, and the lift or crew plan for ceiling sheets agreed before start.
Measurements to confirm
Each wall length and the ceiling height, room by room. Do not assume two opposite walls match.
Ceiling area per room, measured separately from wall area.
Every door and window opening, if you plan to deduct openings from the gross area. Measure each one; do not use a standard guess.
Sheet size choice per area. Long sheets cut butt joints on long walls; smaller sheets are easier in tight or solo work.
Waste allowance. Ten percent suits simple rectangles; cut up rooms with many corners argue for more.
Permits and code notes for Canada, general level
Garage separation, fire separations between units, and certain ceiling assemblies have specific board type and thickness requirements in Canadian codes. Those assemblies are design matters, not estimator choices.
Work in a home built before modern material bans may encounter older materials that need proper assessment before disturbance. Follow provincial guidance for testing and handling.
