Primary Factors Driving Your Final Invoice
Understand the technical drivers that cause bids to vary between low-end estimates and high-end quotes.
Drywall Dust Settling Cycles
Silica dust remains airborne for up to 72 hours following power sanding. Rushing the final clean before airborne dust settles leads to secondary dusting and repeat labor passes.
HVAC Air Duct Contamination
If the central HVAC system ran during sanding without filtration covers, return ducts blow dust back into freshly cleaned rooms continuously.
Sun-Baked Protective Window Film
Protective blue plastic film left on window panes in direct sun for months melts into the glass, requiring solvent scraping.
Common Questions Regarding Post-Construction Costs
Why can you not use a normal household vacuum for construction dust?
Drywall dust and crystalline silica particles are under 0.5 microns in size. Standard household vacuums allow these microscopic particles to pass directly through the motor and exhaust back into the air, while burning out the vacuum motor. Certified HEPA 99.97% filtration is required by OSHA.
How much does post-construction cleaning cost per square foot?
In 2026, post-construction cleaning costs $0.15 to $0.25 per sq ft for Phase 1 rough cleans, $0.25 to $0.45 per sq ft for Phase 2 final move-in cleans, and $0.10 to $0.15 per sq ft for Phase 3 touch-ups.
