1. Why Post-Construction Cleaning Destroys Unprepared Cleaners
Contractors will call asking: "Can you come clean a 4,000 sq ft new build tomorrow? Just give me your standard deep clean rate."
If you treat a new construction site like a residential deep clean, you will ruin your equipment. Fine silica drywall dust ruins standard residential vacuum motors within hours. Paint overspray on window glass requires specialized razors and brass wool. Silicone caulk on tile floors requires non-destructive solvents.
Post-construction is an industrial service and must be estimated accordingly.

3. Critical Contract Clauses: Protect Your Business
Every post-construction contract must include these three non-negotiable legal protections:
- Tempered Glass Waiver: Modern tempered glass frequently contains microscopic "fabricating debris" (glass nodules from the roller furnaces). Standard scraping can dislodge these nodules, leaving scratches. Your contract must explicitly state that the builder assumes liability for glass scratching unless negligence is proven.
- Utility Requirement: The general contractor must guarantee fully functional electrical power, working lighting, running hot water, and operational climate control (HVAC). If power or water is absent on arrival, an automatic $150 remobilization fee applies.
- Trade Interference Clause: If other subcontractors (plumbers, painters, electricians) are actively working in areas being cleaned, additional cleaning required due to re-contamination is billed at an hourly rate of $55/tech-hour.
