How to Clean After a Renovation or Construction
Post-renovation cleaning is different from regular housecleaning — it involves construction dust that settles everywhere, residues from building materials, and grime that can't be removed with standard cleaning products. Toronto homeowners doing kitchen renovations, bathroom updates, or additions frequently underestimate the scope of cleanup required.
The Two-Phase Approach
Phase 1 — Rough cleanup: Done while work is still ongoing or just completed, before furniture returns. Focuses on removing bulk debris, dust from floors, and protecting surfaces from ongoing work.
Phase 2 — Final clean: After all tradespeople have left and before furniture, appliances, and fixtures are finalized. This is the thorough clean that makes the space habitable.
Construction Dust — Why It's Different
Drywall dust (calcium sulfate), wood dust, concrete dust, and grout haze are all finer than regular household dust and behave differently:
- They settle on every surface including inside cabinets, HVAC vents, and inside light fixtures
- When wetted, they form a paste that's harder to remove than dry
- Drywall dust scratches surfaces (glass, appliances, hardwood) when scrubbed dry
- They can damage HVAC systems if not removed from vents before turning on the system
Order of Operations
- HVAC vents first: Replace furnace filters before turning on HVAC. Vacuum vent covers and returns. Running HVAC through construction dust circulates it everywhere.
- Ceilings and high surfaces: Wipe down ceilings, light fixtures, fan blades, and upper cabinet tops with a damp microfibre cloth. Work top-down so falling dust lands on surfaces you haven't cleaned yet.
- Walls: Wipe with a damp cloth to remove dust film. For textured walls, a barely damp sponge mop is effective.
- Cabinets and built-ins: Wipe all interior shelves and door fronts — dust gets inside every cabinet.
- Windows and frames: Clean glass carefully — drywall dust is abrasive and scratches glass when dry-wiped. Always dampen first.
- Floors — vacuum first, then mop: Never sweep — it raises dust into the air. Vacuum thoroughly, then damp mop. For hardwood: use a barely damp mop (excess water damages hardwood). For tile: full wet mop to remove grout haze.
Grout Haze on New Tile
New tile installations leave a haze of dried grout on the tile surface. This needs a specific grout haze remover (available at tile stores and Home Depot) applied and buffed off within the first week — the longer it sets, the harder it is to remove. Follow the product directions for your specific tile type.
Paint Overspray
For fresh paint overspray on glass or hard surfaces: use a razor scraper (held at 30 degrees) on glass, or painter's tape residue remover on other surfaces. For dried latex paint on hard floors: a damp cloth often removes it if caught early. For stubborn dried paint: a small amount of rubbing alcohol on a cloth.
When to Hire Post-Construction Cleaners
For large renovations (full kitchen, bathroom, addition), professional post-construction cleaning is worth the cost — the volume of dust and debris exceeds what a standard home clean can address efficiently. Maidless offers post-construction cleaning across Toronto. Book at maidless.ca.
