After a build or remodel, the space looks finished but rarely feels finished. Fine dust from drywall, sanding and cutting settles on every horizontal surface, works its way into tracks and vents, and resettles for days. A structured after construction cleaning pass works top to bottom so nothing gets re-dirtied by the step above it.
Work top to bottom, dry to wet
The order matters more than the products. Start at ceiling height, finish at the floor, and dry-remove dust before introducing water — wet cloths on heavy dust turn it into a film that is far harder to lift.
1. Ceilings, lights and vents
Light fittings, fan blades, sprinkler heads, extract grilles and the tops of door frames. Vents deserve particular attention: construction dust is carried through HVAC systems and will keep reappearing if grilles and returns are skipped.
2. Walls, frames and joinery
Wipe down walls for splatter and hand marks, then skirting, architraves, door faces and hinges. New paint and fresh caulk are soft — use light pressure and a plain damp cloth rather than an abrasive.
3. Windows and glass
Remove protective film and label residue, vacuum the tracks before wetting them, then clean glass on both faces. Paint specks come off wet glass with a blade held flat, never dry.
Kitchen and bathrooms
These rooms hold the most detail. Cabinets are cleaned inside, on top and underneath; drawer runners and hinge pockets collect sawdust. Appliances get their protective film removed and their interiors wiped. In bathrooms, grout haze, silicone smears and adhesive rings around fittings are the common leftovers.
Floors last, and twice
Vacuum with a suitable filter first, then mop hard floors. A second pass the following day is normal on larger jobs, because airborne dust keeps landing for a while after the trades leave. Carpet laid before the final clean usually needs extraction rather than vacuuming alone.
Why construction dust is treated differently
Dust from cutting concrete, masonry, brick and some engineered products can contain respirable crystalline silica, which OSHA regulates under its respirable crystalline silica standard because of the respiratory risk. That is the practical reason a proper renovation cleaning crew uses filtered vacuums and dust-capture methods instead of sweeping and blowing dust around.
The final walkthrough
Go through the space with the light low and from an angle — side light reveals streaks, haze and missed dust that overhead light hides. Check the places people forget: window reveals, the tops of doors, inside cabinetry, behind toilets, and the outside of any glazing that will be hard to reach later.
When to book it
Book the detail clean after the last trade has left and before furniture, flooring protection or handover. If trades will return, a light touch-up pass afterwards is cheaper than repeating the whole clean.
