Post-construction cleaning for commercial builds: what it costs
Post-construction cleaning for commercial space in Alberta runs $0.50 to $0.80 per square foot — several times the $0.08 to $0.20 rate for routine commercial cleaning, because it's a different job entirely. A 2,000 square foot retail fit-out costs roughly $1,000 to $1,600 to bring from construction-done to move-in ready. A 10,000 square foot office floor is $5,000 to $8,000. Here is what that money buys, phase by phase, and how to time it against handover.
Why it isn't janitorial
A janitorial crew maintains a clean building. A post-construction crew creates one. Construction leaves drywall dust in every crevice — inside cabinets, on top of door frames, coating light fixtures and HVAC grilles — plus adhesive residue, paint overspray, stickers on every pane of glass, and debris the trades left behind. Cleaning it takes industrial vacuums with fine-dust filters, razor work on glass, and two or three passes as dust keeps settling for days after the trades leave. That's why the rate is three to six times the janitorial rate, and why hiring your regular office cleaner for it usually disappoints both of you.
The three phases
| Phase | When | What it includes | Rough share of cost |
|---|---|---|---|
| Rough clean | After framing, drywall and major trades; before flooring and finishes | Debris and packaging removal, sweep and shop-vac of floors, first knockdown of heavy dust | ~20–25% |
| Final clean | After the trades are out | Top-to-bottom detail: every surface, inside cabinets and closets, fixtures, baseboards, window and glass detailing, sticker and residue removal, floors scrubbed, washrooms sanitized | ~60% |
| Touch-up clean | Days before occupancy or handover | Re-dust everything that settled, polish glass and stainless, final floor pass, walkthrough-ready presentation | ~15–20% |
The final clean is the expensive one because it's the detailed one. Windows are the line item that surprises people: construction glass needs razor scraping and detailing, not just a wipe, and some cleaners quote it per pane on top of the square-foot rate.
What it costs by build size
| Build | Size | Typical total (CAD) |
|---|---|---|
| Retail unit fit-out | 2,000 sq ft | $1,000–$1,600 |
| Restaurant or clinic build-out | 4,000 sq ft | $2,000–$3,200 |
| Office floor | 10,000 sq ft | $5,000–$8,000 |
| Small commercial building | 40,000 sq ft | $20,000–$32,000 |
All three phases are inside the $0.50 to $0.80 per square foot range. Skipping the rough clean saves money up front but pushes work into the final clean, so the total rarely changes much. Heavy debris removal, exterior high-rise glass, and specialty floor treatment (stripping and sealing new VCT, for example) are quoted separately. Add 5 percent GST.
Timing it against occupancy and handover
The touch-up clean is what your client, tenant, or inspector actually sees, so schedule backward from the handover date. In Calgary, a commercial build needs its occupancy approval — the City's final confirmation the building is safe to occupy — before anyone moves in, and the walkthrough goes better in a spotless space. Book the final clean for when the trades are genuinely finished, not when they're supposed to be finished; every trade who comes back after the final clean undoes part of it. Leave two or three days between final clean and touch-up so airborne dust has settled, and keep the touch-up within a day or two of handover.
Contractors in Calgary and Edmonton often hold back the cleaning booking until the deficiency list is closed for exactly this reason. In fast-growing markets like Airdrie, book post-construction crews two to three weeks ahead — the good ones are scheduled out.
What to confirm before you book
- WCB Alberta coverage, liability insurance, and bonding — same as any commercial cleaner, but doubly important on an active site where a general contractor's insurance also applies.
- Whether debris hauling and bin costs are included or extra.
- Who supplies lifts or ladders for high dusting and high glass.
- Whether interior windows are in the square-foot rate or quoted per pane.
- That the quote names all the phases you're buying, so "post-construction clean" doesn't turn out to mean one pass.
If the finished space is a clinic, cleaning standards don't end at handover — see our guide to medical and dental office cleaning for what patient-ready means and costs.
Frequently asked questions
How much does post-construction cleaning cost per square foot?
In Alberta, $0.50 to $0.80 per square foot for commercial space, covering rough, final and touch-up phases. A 10,000 square foot office floor runs $5,000 to $8,000.
What's included in a final clean?
Top-to-bottom detailing: every surface and fixture, inside cabinets, baseboards, sticker and residue removal, razor-detailed glass, scrubbed floors and sanitized washrooms. It's roughly 60 percent of the total cost.
Can my regular janitorial company do it?
Usually not well. Construction dust and residue need industrial vacuums, razor work and multiple passes — different equipment and pace than maintenance cleaning, which is why the rate is three to six times higher.
When should the final clean happen?
Only after the trades are completely done, with a touch-up pass a day or two before handover or occupancy inspection. Trades returning after the final clean undo it.
