Post Construction Cleaning Cost: What Drives the Price

A general contractor calls two weeks before a Plano office fit-out turns over, and the first question is always the same. What is this going to run? Post construction cleaning cost in the DFW market generally lands between $0.30 and $0.60 per square foot for a full three-phase commercial job.

That is a wide range, however the spread is not random. Specifically, the number moves with debris volume, finish materials, jobsite access, and how many trades are still working when the crew arrives.

Short version: most commercial post construction cleaning is quoted per square foot across three phases. Rough clean runs roughly $0.10 to $0.20 per square foot, the final clean runs $0.15 to $0.35, and the touch-up clean runs $0.05 to $0.15. Hourly pricing generally falls between $35 and $55 per cleaner. Small jobs under 5,000 square feet usually carry a minimum charge.

What Does Post Construction Cleaning Cost Per Square Foot?

For most commercial buildouts in North Texas, expect $0.30 to $0.60 per square foot total across all three phases. A 20,000 square foot office fit-out therefore lands somewhere around $6,000 to $12,000.

The phases price separately, specifically because they are genuinely different work:

• Rough clean (phase one): $0.10 to $0.20 per square foot. Debris haul-out, sweeping, and clearing the space so trades can finish.
• Final clean (phase two): $0.15 to $0.35 per square foot. Detail work on glass, fixtures, casework, vents, and floors.
• Touch-up clean (phase three): $0.05 to $0.15 per square foot. The pass after punch list items get corrected, right before handover.

Some contractors only buy phase two and three. That lowers the invoice, however it usually means the general contractor absorbed rough cleanup with its own labor. As a result, the savings often show up somewhere else on the job cost.

Why Is Post Construction Cleaning Priced Per Square Foot?

Square footage is the closest available proxy for how long the work takes, and every estimator in this market uses it. Because the crew has to touch nearly every surface in the space, area predicts labor hours better than any other single number.

The method breaks down at the edges, though. A 4,000 square foot medical suite with twelve exam rooms takes longer per square foot than a 40,000 square foot open warehouse. That is why an honest quote comes from a walkthrough rather than a number typed into an email.

What Makes a Post Construction Cleaning Quote Go Up?

Seven things move the number more than anything else, and they are worth reviewing before you sign. In fact, most quote disputes trace back to one of these being different on site than it was on the phone.

• Drywall dust volume. Heavy sanding puts fine dust in every vent, track, and ledge. That can add 20 to 40 percent to phase two labor.
• Glass and glazing. Storefront and full-height interior glass need scraping and polishing, which is slow, careful work.
• Floor type. Polished concrete and natural stone need different chemistry and machines than VCT or carpet tile.
• Ceiling height. Anything above 12 feet means lifts, and lifts mean rental cost plus slower production rates.
• Occupied phasing. Cleaning around active tenants or working trades forces stop-and-start scheduling.
• Access and timing. Night work, weekend turnover, loading dock limits, and badge-in requirements all add hours.
• Debris disposal. If the dumpster is gone before the crew arrives, hauling becomes a separate line item.

Should You Pay Per Square Foot or Per Hour?

Per square foot works when the scope is defined and the space is ready. As a result, it moves the risk to the cleaning contractor, and it gives you a fixed number to carry in your budget.

Hourly pricing, generally $35 to $55 per cleaner in DFW, makes more sense when the scope is genuinely unknown. For example, a phased renovation in an occupied building rarely holds still long enough to quote flat.

Be cautious with a flat bid that arrives without a site visit. A contractor who has not seen the dust either padded the number heavily or plans to issue a change order later. Therefore a walkthrough protects both sides, because it settles scope while the schedule still has room.

What Is Usually Not Included in the Quote?

In fact, scope gaps cause more friction than price does. Therefore it helps to confirm these in writing before the crew mobilizes:

• Exterior windows above the ground floor, which often need a separate glass contractor.
• Floor sealing, waxing, or burnishing, which are finish services rather than cleaning.
• Dumpster rental and construction debris haul-off.
• Air duct cleaning, which requires a licensed HVAC contractor.
• Replacement of filters, tracks, or hardware damaged during construction.

Our post construction cleaning checklist lays out what a complete three-phase scope actually covers, which makes these gaps easier to spot in a bid.

Does Medical or Lab Space Cost More to Clean?

Yes, and the difference is significant. Medical suites, dental offices, and lab space generally run 25 to 50 percent above standard office rates on the same square footage.

The reason is fixture density. For example, a 6,000 square foot clinic can hold fourteen exam rooms, two restrooms, a lab, and a sterilization area, so the crew is cleaning far more surfaces per square foot than an open office floor.

Material sensitivity adds to it as well. Because epoxy floors, sealed casework, and equipment surfaces each need specific chemistry, the crew cannot move at production speed. Food service space behaves the same way, since stainless steel and hood areas require their own approach.

How Do You Compare Two Post Construction Cleaning Bids?

Put both bids on the same scope before you compare totals, because otherwise the comparison means very little. A bid that looks 30 percent cheaper is often quoting two phases against a competitor’s three.

Ask each contractor four questions. First, which phases are included. Second, how many crew members and how many days. Third, whether lifts and equipment are in the price. Fourth, what happens if the punch list runs long and the crew has to return.

Insurance matters here too. Confirm general liability and workers compensation before anyone works on an active jobsite, because the general contractor will ask for certificates anyway.

Payment terms are worth settling early as well. Since many post construction jobs invoice by phase rather than at completion, agreeing on that schedule up front avoids a slow conversation during turnover week.

How Long Does Post Construction Cleaning Take?

For planning purposes, phase two generally runs 1,000 to 1,500 square feet per cleaner per day on standard office finishes. A 20,000 square foot suite therefore needs roughly four cleaners for three to four days.

Medical, lab, and food service spaces run slower, however, because the fixture count per square foot is higher. Warehouse and open industrial space runs faster, sometimes double the rate above.

Build a buffer into the turnover date. Punch list work almost always pushes the touch-up clean later than the original schedule assumed, and the crew cannot start the final pass while trades are still cutting.

Post Construction Cleaning in Dallas and Fort Worth

We serve Dallas, Fort Worth, Arlington, Plano, Irving, and the wider DFW area. Because our teams also handle recurring janitorial work, many clients keep us on after turnover for ongoing service in the same building.

If you have drawings and a turnover date, that is enough to get a real number rather than a range. Schedule a no-pressure walkthrough of your project, and we will price it phase by phase so you can see exactly what you are buying.
