Drywall dust gets everywhere — inside vents, on top of frames, filmed over every pane of glass. A post-construction clean is a different trade from nightly janitorial, and pricing it that way saves arguments at handover.
Rough, detail, polish
Plan three passes: debris and sticker removal first, then drywall-dust detailing of every horizontal surface, then glass, frames, and a final polish walk.
Book the walkthrough before you book the clean
Agree in writing what 'done' looks like — finger-test on sills, tape-free glass, dust-free vents. Then the final walkthrough takes minutes, not a second visit.
On a 40-storey tower build-out, this sequence is what gets you a dust-free handover on schedule.
