Post-Construction Cleaning Cost per Square Foot, Explained
Why post-construction cleaning runs $0.22–$0.44 a square foot, why small jobs cost more per foot, and what the three cleaning phases each cover.
Post-construction cleaning is priced per square foot almost everywhere, which makes it look simple and hides the one thing that matters: the rate is not flat across sizes.
The actual numbers
Our post-construction pricing is a base fee plus a per-square-foot rate. Written out as an all-in cost per foot, it looks like this:
| Space | Total | Effective per sq ft |
|---|---|---|
| 1,000 sq ft | $365–$440 | $0.36–$0.44 |
| 2,000 sq ft | $565–$690 | $0.28–$0.34 |
| 2,600 sq ft | $685–$835 | $0.26–$0.32 |
| 4,000 sq ft | $970–$1,180 | $0.24–$0.29 |
| 8,000 sq ft | $1,780–$2,165 | $0.22–$0.27 |
The per-foot rate falls as the job grows. That is not a volume discount in the marketing sense — it is the base fee spreading over more floor. Setup, equipment haul, HEPA vacuums, water, disposal and the first hour of a crew’s time cost roughly the same whether the space is 1,000 or 8,000 square feet.
Which means: if you are comparing a $0.25/sq ft quote on a 900 sq ft remodel against a $0.25/sq ft quote on a 6,000 sq ft build, one of them is wrong. Small jobs cost more per foot. Any bid that ignores that is either underpriced and will be revised, or the small job is subsidising nothing and you are overpaying on the big one.
What phase you are buying
“Post-construction cleaning” describes three different jobs, and the per-foot number is meaningless without knowing which one.
Rough clean. After framing, before finishes. Debris removal, sweeping, getting the space workable for the next trades. Cheapest per foot, and it is not a finish clean.
Final clean. The one people mean. Every surface, window interiors, inside cabinets and drawers, fixtures, appliance protective film, sticker and adhesive removal, floors done to their finished state. This is what the rates above describe.
Touch-up. After the punch list, immediately before handover or photography. Small, fast, and priced closer to a standard clean because the heavy work has been done.
A bid that does not name the phase is not comparable to one that does.
Why it is three to four times a standard clean
A 2,600 sq ft house costs $685–$835 post-construction and around $310–$380 for a standard one-time clean. The gap is drywall dust.
Drywall dust is not ordinary dust. It is fine, it is everywhere, it is electrostatically inclined to settle back onto surfaces you just cleaned, and it lives inside HVAC returns, light fixtures, window tracks and the top edge of every door. A single pass does not finish it. Crews work top-down and expect to return to surfaces after the air settles, which is why the job is measured in crew-days rather than hours.
Then there is the material that is not dust: paint overspray, silicone smears, grout haze, adhesive from protective film, joint compound splatter, sawdust in cabinet runners. Each needs a different removal method and some need a blade.
What drives your number up
- Windows. The largest single variable. A wall of glass in a Westlake or Lakeway build changes the bid materially, and exterior glass above ground floor changes it again.
- Bathrooms and kitchens. Fixture density, not floor area.
- Flooring type. Polished concrete, natural stone and unsealed tile all have their own rules. Grout haze on new tile is its own line of work.
- Ceiling height. Twelve-foot ceilings mean ladders, and ladders mean time.
- Whether the trades are finished. Cleaning around active work means cleaning twice.
The Austin additions
Two local ones worth budgeting for.
Limestone and caliche dust. Central Texas sites sit on it, and it gets tracked in for the entire build. It is grittier than drywall dust and it scratches. On sites with fresh grading it keeps arriving until the landscaping goes in.
Hard water. New fixtures and new shower glass get their first exposure to Austin water during construction testing and cleanup. Spots left to dry on brand-new glass are already mineral deposits by handover, and they need an acid descaler with dwell time, not a squeegee.
Getting a bid you can compare
Ask every bidder for four things: the phase, the square footage they priced, whether windows are included and to what height, and how many crew-days they have allowed. Two bids with those four fields filled in are comparable. Two bids with a per-foot number are not.
Our post-construction cleans start at $365 and are quoted from the plan set or a walkthrough, whichever you have. If the general contractor and the owner both need to see the scope, we will put it in one document rather than two.
