Post construction cleaning cost per square foot starts with the size of the space, but size is only the first input. The phase of the clean, how much dust and residue the trades left, the amount of glass, cabinets and fixtures, leftover debris, access and any return visits all change the labor, and labor is what the quote prices.
Why is post construction cleaning quoted per square foot?
Square footage is the quickest way to size a job before anyone walks it. A contractor reads it off the plans, and a cleaner turns it into a rough labor estimate. It is a starting point. Two spaces with the same footage can need different amounts of work, so the figure moves once the details are known.
Treat a per square foot number as shorthand for "this much labor for a space like this one." When the space is unlike the one the number assumed, the labor is different, and so is the number.
What is the difference between a rough clean and a final clean?
A rough clean happens while construction is still going on. It clears debris, scraps and heavy dust so the trades can keep working. A final clean comes after the last trade leaves and before the owner walkthrough or move in. It takes fine dust off every surface and details glass, fixtures, cabinets and floors.
Each phase is priced on its own. Some projects also add a touch up pass right before move in to catch dust from late punch list work. Cost guides list these phases with separate rates for that reason. Fixr's post construction cleaning cost guide, updated January 31, 2025, breaks its national per square foot ranges into rough, final, touch up and exterior cleanup.
Southern Charm Cleaning does the final clean. The post construction cleaning checklist covers what that pass includes room by room.
What makes one job take more labor than another?
Dust, glass, paint and adhesive residue, cabinets and fixtures, debris left on site and access all change how long the job takes. A suite where the painters masked well and the trades swept up is a lighter job than one with overspray on the windows and drywall dust in every drawer, even at the same size.
| Factor | Lighter job | Heavier job |
|---|---|---|
| Dust | Trades swept and vacuumed as they went | Drywall dust on every ledge, vent and inside cabinets |
| Glass | Few windows, no storefront | Storefront, interior glass walls, glass shower doors |
| Residue | Labels already off, clean masking | Stickers on every window, paint overspray, adhesive on floors |
| Cabinets and fixtures | Open office, few fixtures | Break room or kitchen millwork, many light fixtures, restroom fixtures |
| Floors | Carpet that only needs vacuuming | Hard floors with grout haze or residue to lift |
| Debris | Packaging already gone | Boxes, scraps and packaging still on site |
| Access | Ground floor, parking at the door, power and water on | Upper floor, long carry from parking, utilities not yet live |
| Ceiling height | Standard ceilings | High ledges and fixtures that need ladders |
Are haul off and return visits included?
It depends on the quote, so ask before you sign. Packaging, scraps and small debris from the final clean are often part of the job. Dumpster loads of demolition debris are a separate job. Return visits after other trades come back are usually extra, because each one is more labor. A written quote should say both things in plain words.
For Southern Charm Cleaning, leftover packaging and small debris from the final clean get hauled off with the crew. Demolition debris is not part of the clean. Tell us what is on site when you ask for a quote.
When does the cleaner need to walk the space?
A walkthrough helps most when the space is large, the finishes are unusual, or the photos do not show the dust and residue. Smaller spaces with clear photos and a square footage can often be quoted without one. When the scope is uncertain, a walkthrough makes the quote match the real job.
Things that usually call for a walkthrough:
- Commercial finish outs with storefront glass or many interior partitions
- High ceilings, exposed ductwork or tall ledges
- Residue you cannot see clearly in photos, such as overspray or adhesive on floors
- Occupied buildings where access, elevators or loading dock times are limited
What happens if construction continues after the clean?
New dust lands on clean surfaces. If an electrician, painter or flooring crew comes back after the final clean, the areas they touched need another pass, and that pass is new labor. To avoid paying twice, schedule the final clean after the punch list is closed and agree in writing on how a return visit is priced.
A short note in the quote such as "return visits after trades come back are quoted separately" saves an argument later. So does a walk with the contractor or owner right after the clean, before anyone else goes back in.
How do the inputs add up? A worked example
The example below was written in November 2026. Both spaces are hypothetical, not client jobs, and they show why one per square foot figure does not fit every space of the same size. No prices are shown. The point is which line items change the labor.
| Input | Suite A | Suite B |
|---|---|---|
| Size | 2,400 square feet | 2,400 square feet |
| Use | Open office finish out | Office with a break room and a glass storefront |
| Glass | Four interior windows | Storefront, two glass conference walls, every pane labeled |
| Cabinets | None | Break room uppers and lowers, inside and out |
| Floors | Carpet tile, vacuum only | Tile in the break room and entry with grout haze |
| Dust | Light, trades vacuumed as they went | Heavy drywall dust on ledges and in vents |
| Debris | Removed by the contractor | Boxes and packaging left in two rooms |
| Access | Ground floor, door parking | Second floor, elevator booked by the hour |
Suite B needs more labor in almost every row, so its quote comes in higher per square foot than Suite A's, even though both are the same size. A per square foot number pulled from a guide or a calculator would treat them the same.
How should you read published per square foot ranges?
Treat them as a rough national guide from the source that published them, not as a Dallas and Fort Worth rate. Cost guides such as Fixr publish ranges by cleaning phase and project type. They help with a budget line before you have quotes, but they do not know your dust, your glass or your access.
If a quote lands well above or below a published range, ask which inputs drove it. A good answer names the line items from the table above.
What should you send to get an accurate quote?
Send the address, the square footage, the move in or walkthrough date, and clear photos of every room, including glass, cabinets, floors and any debris still on site. Say whether the trades are finished and whether power and water are on. With that list, a cleaner can quote from photos or tell you a walkthrough is needed.
A quote request checklist:
- Address, suite number and floor
- Square footage and the type of space
- Date the last trade finishes and the walkthrough or move in date
- Photos of each room, the glass, cabinets and floors
- What debris is still on site
- Parking, elevator and loading dock limits
- Whether power, water and lighting are on
Frequently asked questions
Does a larger space always cost more per square foot?
Not necessarily. Price follows labor, and labor follows the details. A large open space with little glass and no cabinets can need less labor per square foot than a small suite packed with fixtures, millwork and storefront glass. Compare the scope line by line, not only the total footage.
Is window cleaning part of a post construction clean?
Interior windows, tracks, sills and glass are part of a final clean, along with taking stickers and labels off the glass. Exterior high windows that need lifts or rope access are a different job. Ask the cleaner which windows are included and say how many floors the building has.
Can a post construction clean be quoted from photos?
Yes, for many spaces. Clear photos of each room, plus the square footage and the type of finishes, are often enough. Larger commercial finish outs, high ceilings and heavy residue usually call for a walkthrough so the quote matches what the crew will find.
Who should book the final clean, the contractor or the owner?
Whoever is responsible for handing over a clean space under the contract. On commercial finish outs that is often the general contractor. On a remodel it may be the homeowner or the remodeler. Settle it before the last week of the job so the clean is on the schedule.
How do I request a post construction cleaning quote?
Send the address, square footage, finish date and photos by text to (469) 383 8216, or use the quote form. Southern Charm Cleaning does final post construction cleans across Dallas and Fort Worth, including Frisco and McKinney, quoted per job after a walkthrough or from photos.
