First Clean in a New Construction Ontario Home
New construction homes in Ontario present a unique cleaning challenge that differs fundamentally from a standard move-in clean. While many buyers assume a new home will be move-in ready, the reality is that construction processes leave behind fine drywall dust, paint overspray, adhesive residues, and debris that a basic builder clean — typically a cursory wipe-down done before handover — does not address thoroughly. A proper first clean in a new construction home is one of the most important cleaning investments a homeowner can make.
What Builders Leave Behind
- Drywall dust: The fine white dust from drywall sanding is pervasive — it settles on every horizontal surface, inside cabinets, in window channels, and on window sills. It requires vacuum removal before wiping, as wiping drywall dust dry spreads it further
- Paint overspray and drips: Ceiling paint on the tops of walls, floor paint on baseboards, trim paint on floors — all standard artifacts of production construction
- Adhesive residues: Window and appliance protective films leave adhesive residue; flooring adhesive can be tracked by workers during install
- Construction debris: Sawdust in corners, drywall chips in cabinets, concrete dust in the garage and basement
- HVAC contamination: The HVAC system is typically run during construction — ducts accumulate construction dust that circulates through the home when the system runs
The New Construction Cleaning Priority List
- HVAC filter replacement (immediately — replace the construction-era filter)
- Full vacuum of all surfaces before wiping — drywall dust must be vacuumed, not swept
- Windows cleaned inside (exterior is typically done by the builder)
- All cabinetry interior wiped
- Appliances cleaned inside and out
- All floors cleaned with appropriate method for the floor type
Professional vs DIY
Given the scope and the specialized nature of construction dust (fine particles that require HEPA filtration vacuum equipment), professional post-construction cleaning is strongly recommended for new Ontario builds. Budget $350–$600 for a new home of typical GTA new construction size (1,500–2,500 sq ft). Book at maidless.ca/ontario.
