Post-Construction Cleaning Calculator
Post-construction work is high-value and easy to underbid. Enter the square footage, phase, and debris level, and get crew hours, a bid price, and price per square foot — built from labor, the way the job actually costs out.

Most post-construction final cleans land between $0.30 and $0.50 per square foot; multi-phase jobs and heavy debris run higher. Treat this as a starting point and always walk the site before you commit to a number.
How the estimate is calculated
A post-construction bid lives and dies on the hours. The calculator starts from a baseline detail-clean rate, then scales it up or down for the phase you are doing and how dirty the site is.
Phase multiplier
A rough clean is mostly debris removal and runs lighter than a final clean. A touch-up is lighter still. All three phases together carry the most hours. Each phase scales the baseline accordingly.
Debris level
Light, average, or heavy. Heavy drywall dust, adhesive, and paint haze can add nearly half again to the hours because every surface needs more passes.
Cost to bid
Adjusted hours times your labor rate, plus supplies, overhead, and margin. The result is a flat bid price and a price per square foot you can check against the typical $0.30 to $0.50 range.

Frequently asked questions
- How much should I charge for post-construction cleaning?
- Most post-construction final cleans land between $0.30 and $0.50 per square foot, with heavy debris and multi-phase jobs running higher. Price off labor hours: estimate how long the detail work takes, apply your burdened labor rate, add supplies, overhead, and margin. This calculator does that math by phase and debris level.
- What are the phases of post-construction cleaning?
- There are typically three. The rough clean happens after the major work but before finishes — mostly debris removal. The final (or detail) clean is the thorough pass: dust, surfaces, fixtures, glass, and floors. The touch-up clean handles the punch list right before handover. This tool prices each phase separately or all three together.
- Why is post-construction cleaning priced higher than regular cleaning?
- It is detail work, not routine janitorial. Fine drywall dust settles on every surface and has to be wiped repeatedly, stickers and labels need removing, paint and grout haze need attention, and the site is often unfinished and unsafe. A crew covers far less square footage per hour than on a routine clean, so the price per square foot is higher.
- How do I estimate labor hours for a post-construction clean?
- Divide the square footage by a production rate, then adjust for phase and debris. A detailed residential final clean might run around 150 to 200 sq ft per labor hour; commercial open space goes faster. Heavy drywall dust can add 40% or more to the hours. The calculator applies these multipliers for you.
- Should I charge by the square foot or by the hour?
- Bid the job as a flat price, but build that price from hours. Customers want a number, and a flat bid protects your margin if the work goes faster than expected. Use the hours estimate internally to schedule the crew and check that your square-foot price is profitable.
- Does this estimate include windows and detail work?
- The debris level and phase multipliers account for typical detail work in a final clean, including interior glass. For jobs with extensive exterior windows, specialty floor care, or heavy paint and adhesive removal, add a line item on top of the base estimate.
Run the job, not just the bid
Pillar handles the estimate, the multi-day schedule, the crew checklist, and the invoice — so a high-value post-construction job stays organized from walkthrough to final payment.
