Post-Construction Cleaning Calculator
Pricing from building type, size, and detail level.
About this calculator
This calculator prices the standard three-phase post-construction clean — rough, light/construction, and final/punch — using per-square-foot rates that scale with both construction type and finish detail level. Rough clean (debris and bulk trash removal) and light clean (dusting, vacuuming, surface wipe-down) rates step up across renovation, new build, and heavy industrial/concrete projects, reflecting how much residual dust and debris each leaves behind. The final/punch clean, the detail pass that gets a space walk-through ready, additionally applies a detail-level multiplier — 0.8x for a basic builder clean, 1.0x for standard, and 1.4x for a premium/luxury finish — on top of its own construction-type rate. Window cleaning is priced per window at a $3.50 base that rises 15% for each floor above the first, capturing the added time and access equipment multi-story buildings require.
That same per-floor logic (5% per floor above ground) is applied to the three phase costs together, not to windows, before windows are added back in separately. Labor hours are derived from a 600 sq ft/hour production rate that gets slower as the detail multiplier rises, plus a flat 8 minutes per window. Because the floor premium compounds with the detail multiplier only on certain cost lines, small changes to floors or detail level can shift the total by more than a simple linear scaling would suggest — worth double-checking against your own crew's historical production rates before quoting a fixed bid.

How to Use This Calculator
- Enter the total building area in square feet and the number of windows.
- Set the number of floors -- multi-story adds a height premium per floor above ground.
- Enter your hourly labor rate for the cleaning crew.
- Select the detail level (1 = builder clean, 2 = standard, 3 = premium/luxury).
- Review the three-phase cost breakdown (rough, light, final) plus window cleaning to build your bid.
How the result changes with Building area (sq ft)

- Phase 2: Light clean
- Dusting, vacuuming, surface wiping.
- Phase 3: Final/punch clean
- Detail cleaning, fixture polishing, client walk-through ready.
- Window cleaning cost
- Interior and exterior window cleaning.
- Estimated labor hours
- Total crew hours across all phases.
- Labor cost estimate
- Labor hours multiplied by hourly rate.

Frequently Asked Questions
How does construction type change the pricing for each phase?
Construction type sets a per-square-foot rate for rough, light, and final cleaning that steps up across three tiers: renovation/remodel is cheapest (rough $0.08, light $0.15, final $0.30 per sq ft before the detail multiplier), new build is in the middle (rough $0.15, light $0.25, final $0.45), and heavy industrial/concrete is highest (rough $0.22, light $0.32, final $0.60). Heavy industrial and concrete jobs leave the most dust and debris, which is why their rates are highest across all three phases.
What does the detail level multiplier apply to?
The detail level (1-3) only multiplies the final/punch clean rate — 0.8x for basic builder-clean detail, 1.0x for standard, and 1.4x for premium/luxury finish work. It does not change the rough or light clean rates, since those two phases are about bulk debris removal and dusting, not the fine finish work a punch clean covers. It also slows the labor-hour production rate proportionally, since more detail work per square foot takes longer per hour of labor.
Why does adding floors affect windows and the other phases differently?
The multi-floor premium (5% per floor above the first) is applied to the combined rough, light, and final clean subtotal, then windows are priced and added afterward using their own separate height adjustment — a 15% increase per floor above the first on the $3.50 base price per window. Because these are two independent multipliers on different cost bases, the total doesn't scale as a single simple percentage per floor.
How are the estimated labor hours calculated?
Labor hours come from a base production rate of 600 sq ft/hour, divided by the same detail multiplier used for the final clean pricing (so higher detail levels also slow labor throughput), then multiplied by the floor premium. Window cleaning adds a flat 8 minutes per window on top of that, independent of floor count or detail level.
