Post-construction cleaning is fundamentally different from regular maintenance. Construction dust penetrates everywhere, adhesive and paint residue cling to surfaces, and debris turns up in unexpected places. A sloppy clean at this stage leaves visible marks on new finishes - and those are expensive to correct after the fact.
The three phases of a construction project
Phase 1 - During construction
Removal of large debris, material packaging, rough waste. Usually handled by the contractor. Not suitable for finish cleaning.
Phase 2 - Rough post-construction clean
Elimination of construction dust, mortar residue, adhesives, excess caulking. This is where most professional services begin.
Phase 3 - Finish cleaning
Precision cleaning of new surfaces: windows, floors, countertops, fixtures. Ready for handover or move-in.

Frequently Asked Questions
When should post-construction cleaning happen after a renovation?
Ideally once all trades have finished their work and large debris has been cleared by the contractor. Bringing cleaners in too early means redoing the finish clean after later stages of the project generate more dust.
Is post-construction cleaning different from a regular deep clean?
Yes. A regular deep clean addresses accumulated household dust and grime. Post-construction cleaning deals with construction-specific residue - drywall dust, adhesive, paint splatter, and mortar - that requires different techniques and products to remove safely from new finishes.
Will cleaning scratch my new floors or windows?
It should not, if the provider uses techniques and products appropriate to the specific surface. Ask how they handle new hardwood, tile, polished concrete, or glass before booking, since the wrong product or tool can damage a brand-new finish.
How much does post-construction cleaning cost in Montreal?
Cost depends on square footage, the extent of the renovation, and how much dust and residue is present. Request a quote based on your specific project rather than assuming a flat per-square-foot rate applies evenly across all jobs.
Do I need to be present during the cleaning?
Not necessarily, as long as access is arranged and any specific instructions about surfaces or areas to avoid are communicated in advance.
