Construction Cleanup Cost Estimator
Estimate post-construction cleanup costs based on square footage, project type, cleanup phase, and regional labor rates.
Formula
Base Cleanup Cost = Square Footage × Base Rate ($/sq ft) × Phase Multiplier × Debris Multiplier × Floor Surcharge × Regional Index
Floor Surcharge = 1 + (Floors − 1) × 0.05
Window Cleaning = Number of Windows × $10 × Regional Index
Pressure Washing = Square Footage × $0.12 × Regional Index
Debris Haul-Away = ($150 + Square Footage × $0.05) × Regional Index
Total Cost = Base Cleanup Cost + Window Cleaning + Pressure Washing + Debris Haul-Away
Estimated Range = Total Cost ± 15%
Base Rates by Project Type: Residential New: $0.15/sq ft | Residential Reno: $0.20/sq ft | Commercial New: $0.13/sq ft | Commercial Reno: $0.18/sq ft | Industrial: $0.10/sq ft
Phase Multipliers: Rough Clean: 0.40 | Final Clean: 0.60 | Both: 1.00
Debris Multipliers: Light: 0.80 | Moderate: 1.00 | Heavy: 1.35
Assumptions & References
- Base rates derived from HomeAdvisor / Angi national averages for post-construction cleaning (2023–2024): $0.10–$0.50/sq ft depending on project type and scope.
- Window cleaning estimated at $8–$15 per window (interior + exterior); $10 used as midpoint average.
- Pressure washing estimated at $0.08–$0.20/sq ft; $0.12 used as midpoint (RSMeans data).
- Debris haul-away includes dumpster rental or junk removal truck; base $150 + $0.05/sq ft reflects typical single-load pricing.
- Multi-floor surcharge of 5% per additional floor accounts for increased labor time and equipment needs.
- Regional index: Low (0.85) = rural/Midwest; Average (1.00) = national; High (1.20) = major metro; Very High (1.40) = NYC/SF/Boston.
- Estimates do not include hazardous material removal (asbestos, lead paint), specialty floor polishing, or HVAC duct cleaning.
- Final range of ±15% reflects variability in contractor pricing, site conditions, and local market competition.
