Commercial carpet cleaning typically costs $2.15-$6.45 per square metre ($0.20-$0.60 per square foot), with many standard office jobs averaging about $3.75-$4.30 per square metre. The final price depends on cleaning method, carpet condition, total area, furniture handling, location, and whether work must happen after hours.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Routine commercial cleaning | $2.15/m² | $3.75/m² | $5.40/m² | $0.20-$0.50 per sq ft for open areas |
| Hot-water extraction | $3.20/m² | $4.85/m² | $8.10/m² | $0.30-$0.75 per sq ft; deeper cleaning and slower drying |
| Small-job minimum | $110 | $225 | $450 | May apply when the area is below 500-1,000 sq ft |
| Stain or spot treatment | $10 | $35 | $100 | Per spot; specialty stains can cost more |
Assumptions: Commercial carpet in accessible U.S. office space, standard detergent, ordinary soil, and no major furniture moving or restorative work.
Common add-ons include spot treatment at about $10-$100 per stain, depending on size and substance; carpet protection at roughly $0.10-$0.30 per square foot; and deodorizing at about $0.05-$0.20 per square foot. Urine, dye, adhesive, and oily stains may need specialty treatment, and some cannot be fully removed without damaging fibers. Ask whether the quoted rate includes a limited number of spots or charges for each one.
Furniture moving can add $0.10-$0.30 per square foot, although some contractors price it by room, technician hour, or item. Clearing desks, conference rooms, and floor areas in advance may avoid some of that cost. The building should clarify who moves computers, fragile items, filing cabinets, and furniture with contents; cleaners commonly exclude items that require special handling.
After-hours access can add 10%-30% to labor, and rush scheduling may cost another 10%-25%. These premiums are more common when work must fit a short closure window or fall on a holiday. Travel, parking, loading-dock reservations, and building security coordination can also create charges. Ask for a separate line item for each add-on so optional services are not mistaken for the base square-metre rate.
Where Building Managers Can Trim the Carpet-Cleaning Bill
Start by defining the area and frequency precisely. Measure carpet rather than total rentable floor area, identify rooms that are excluded, and note whether partitions or furniture block access. If only traffic lanes need intensive treatment, ask for a separate price for those lanes and a lower-rate maintenance clean for the rest. This avoids paying a full restorative rate for lightly used rooms.
Scheduling work during normal business hours may reduce labor premiums if the building can close sections safely. Grouping multiple floors or nearby sites into one visit can also spread setup and travel costs, particularly where each small area would otherwise be subject to a minimum. For recurring service, compare the annual schedule and per-visit price with a one-time quote; do not assume a contract discount is worthwhile without checking the total frequency.
Get at least three itemized quotes based on identical square footage, method, and scope. Ask each provider to state the rate per square foot and per square metre, minimum charge, labor assumptions, furniture policy, drying time, and exclusions. Avoid unnecessary add-ons unless the carpet condition warrants them, but do not choose solely by the lowest figure: a very low rate may omit pretreatment, stain work, or adequate extraction.
Preparation can lower billable labor. Remove small items, clear access to rooms, reserve elevators and loading areas, and mark known stains before the crew arrives. A short site walkthrough can prevent a surprise charge for locked rooms or difficult access. For recurring budgets, record the cleaned area, method, drying time, and results after each visit; those records make it easier to adjust frequency and catch costs that do not improve carpet condition.
