How to Clean Up After a Home Renovation
Post-renovation cleaning is fundamentally different from regular housecleaning. Construction dust — particularly drywall dust (calcium sulphate) — is very fine and settles on every horizontal surface in the home, penetrates into HVAC systems, and re-suspends in the air when disturbed. Done wrong, it makes a bigger mess. Here's the right order and approach.
Before You Start
- Wait until all construction work is done — cleaning during active construction just means you clean twice
- Open windows and run bathroom and kitchen exhaust fans to ventilate
- Change your HVAC filter before cleaning — if the system ran during the renovation, it may be clogged with drywall dust and distributing particles throughout the home
The Right Order: Top to Bottom, Dry to Wet
This order prevents re-depositing dust onto already-cleaned surfaces.
Step 1 — Rough cleanup and debris removal
- Remove all construction debris — scraps, packaging, nails, fasteners
- Use a stiff broom to sweep up the heaviest debris from the work area
Step 2 — Dry vacuuming (critical step)
- Use a shop vac (wet/dry vacuum) rather than a regular vacuum — regular vacuums may not handle the volume of fine dust, and their filters may not capture fine drywall particles
- Vacuum all surfaces from the ceiling down: shelves, tops of cabinets, windowsills, countertops, and finally the floor
- Vacuum walls if visible dust coating is present
- Vacuum the floor thoroughly — do not sweep, as sweeping re-suspends fine dust in the air
- Allow 20–30 minutes for re-suspended dust to settle after vacuuming before wiping surfaces
Step 3 — Damp wipe all surfaces
- Wipe all surfaces with a damp microfibre cloth — the moisture captures fine dust rather than spreading it
- Work top-to-bottom: cabinets, shelves, countertops, appliances, then lower surfaces and baseboards
- Change cloths frequently — a cloth saturated with drywall dust just smears
- Wipe light fixtures and ceiling fans — these accumulate significant dust during renovations
Step 4 — Floor cleaning
- Vacuum again after wiping surfaces (more dust will have settled)
- Damp mop hardwood and tile floors — multiple passes may be needed
- For carpet: vacuum multiple times with fresh vacuum passes. Consider professional carpet cleaning if significant drywall dust settled on carpet.
Step 5 — HVAC and vents
- Vacuum all HVAC vents and returns
- Change furnace filter
- Consider having ducts professionally cleaned if the renovation was extensive and ducts ran during construction
