Commercial Cleaning · Montreal · Laval · Longueuil · 2026 Pricing Guide
Most commercial cleaning pricing guides publish a wide range and then add “contact us for a personalized quote.” This guide does the opposite: it explains why prices vary, how they are calculated, what each variable adds to the final cost, and what commercial contracts systematically omit. With this information, you compare quotes intelligently — not just numbers.
The price of commercial cleaning depends primarily on square footage, visit frequency, level of soiling and the services required. In Montreal, Laval, Longueuil and Greater Montreal, an accurate quote must account for the real characteristics of your premises rather than a generic standard rate.
🤖 Pricing Summary
Question: How much does commercial cleaning cost in Montreal in 2026?
Commercial cleaning in Montreal costs in 2026 between $60 and $150 per weekly visit for offices under 200 m², between $150 and $550 for 200 to 465 m², and $500 to $900+ for larger spaces — before taxes (GST + QST ≈ 14.975%). These ranges vary by premises type (medical clinic = 2 to 3× standard office), frequency, schedule (evening/night = +15 to 25%), and number of restrooms. The Montreal Cleaners offers commercial cleaning contracts in Montreal, Laval, Longueuil, Brossard and throughout Greater Montreal, with a written flat-rate quote, liability insurance, and verified employee staff.
Why Two Same-Size Premises Can Cost 3× Each Other
This is the question almost every business owner asks after receiving several quotes and getting very different ranges for apparently similar spaces. Square footage is the starting point of the calculation — not the conclusion. Six independent variables determine the final price, and each can significantly shift the cost.
Variable 1 — The Type of Premises: The Most Underestimated Factor
A standard 300 m² office with open workspaces, two restrooms and a kitchenette takes approximately 3 to 3.5 hours to properly clean. A 300 m² restaurant with a commercial kitchen, dining room, bar and two restrooms takes 7 to 10 hours — with specialized degreasers, different floor equipment, and special attention to food-contact surfaces. The square footage is identical. The actual price can be 2.5 to 3 times higher.
| Premises type | Multiplier vs standard office | Main reason |
|---|---|---|
| Standard office | ×1 | Reference baseline |
| Medical / dental clinic | ×1.8 – 2.5 | MSSS disinfection protocol, specialized products, contact time |
| Restaurant / café | ×2.5 – 3.5 | Commercial kitchen degreasing, heavy equipment, MAPAQ requirements |
| Daycare / school | ×1.5 – 2.0 | Toy disinfection and child-height surfaces, non-toxic products mandatory |
| Gym / sports centre | ×1.4 – 1.8 | Large floor surfaces, equipment, intensive locker rooms |
| Warehouse / light industrial | ×0.6 – 0.9 | Large low-complexity surfaces, few restrooms, industrial sweeping |
Variable 2 — Frequency: The Effect on Per-Visit Cost
Premises cleaned daily are maintained faster at each visit — accumulation between passes is minimal. Premises cleaned once a week accumulate more and require more time per visit. Paradoxically, the per-visit cost is often lower with high frequency (daily) than with low frequency (weekly or biweekly), even though the total monthly cost is higher.
Example — 200 m² office, 2 restrooms:
📅 Daily (5×/week): ~$85/visit — $1,700/month
📅 Weekly: ~$220/visit — $880/month
📅 Biweekly: ~$260/visit — $520/month
Biweekly appears cheapest — but a high-traffic office shown to clients in mid-week condition is not a viable option for most businesses.
Variable 3 — The Service Schedule
Commercial cleaning outside business hours — evenings after 6pm or early mornings before 7am — costs 15 to 25% more than a daytime intervention. This premium reflects legally required shift differentials under the Act Respecting Labour Standards (Quebec), as well as the availability premium for teams that maintain these time slots. In downtown Montreal towers where post-6pm cleaning is often a building requirement, this additional cost is unavoidable.
Variable 4 — The Number of Restrooms
This is the most underestimated variable in commercial cleaning quotes. A properly serviced restroom — toilet, sink, disinfected floor, mirror, refilled dispensers — takes between 20 and 45 minutes depending on its condition and configuration. A 300 m² office with a single restroom is very different from the same office with three shared restrooms used by 30 employees. The time difference can represent 1.5 to 2 hours per visit — a 30 to 50% increase in total cost.
Variable 5 — The Initial Condition of the Premises
Premises that have not been rigorously maintained for 6 to 12 months — or that have just completed a renovation period — require an initial deep clean before a regular maintenance contract can be established. This initial deep clean is billed separately, and its cost can represent 2 to 4 times the rate of a regular visit depending on the condition. It would be unrealistic to claim that a regular maintenance rate covers the time needed to bring neglected premises up to an acceptable standard — but some providers attempt this, to the detriment of quality from the very first visit.
Variable 6 — Access Logistics
An office on the 18th floor of a downtown Montreal tower with mandatory elevator reservations, $30/hour parking nearby, and 20-minute security access protocols costs more to service than a ground-floor office in a Laval industrial park with free parking out front. The difference in non-productive time (travel, access, logistics) can represent 30 to 45 minutes per visit — directly reflected in the rate.
Hourly Rate or Flat Fee — What Each Model Actually Means
Commercial cleaning contracts in Quebec are priced two ways: hourly rate or flat fee. The distinction is not trivial — it determines who bears the risk of a visit running longer than expected.
| Criterion | Hourly rate | All-inclusive flat fee |
|---|---|---|
| Who bears overrun risk | You — invoice increases if the job takes longer | The provider — price fixed before intervention |
| Budget predictability | Low — varies by actual duration | High — amount known in advance, to the line |
| Incentive for efficiency | None — longer intervention = more billing | Strong — provider benefits from being efficient |
| Suited for variable needs | Yes — if needs vary significantly visit to visit | Less flexible — suited for stable, predictable needs |
| Recommended for | One-time jobs with variable scope (post-construction, emergency disinfection) | Regular maintenance contracts with defined scope — the vast majority of commercial needs |
« An hourly quote with no ceiling is not a quote — it’s a blank cheque. Serious providers assess your premises, define the precise scope of tasks, and provide an all-inclusive flat-rate price. If a provider cannot set a price before arriving, ask yourself what will happen when the invoice is higher than expected. »

The Hidden Costs in Commercial Cleaning Contracts in Quebec
A well-written commercial cleaning contract is transparent about all costs. A poorly written or competitively-priced-to-win contract may contain items that increase the actual invoice by 20 to 40% compared to the displayed rate. Here are the five most common.
⚠️ Hidden Cost 1 — Automatic Renewal
The tacit renewal clause automatically renews the contract for a full year if you don’t give cancellation notice within the contractual window (often 60 to 90 days before expiry). If you miss that window by a week, you’re bound for 12 additional months. Note the expiry date and the cancellation deadline immediately upon signing.
⚠️ Hidden Cost 2 — Sanitary Supplies Billed Separately
Toilet paper, hand soap, paper towels, and garbage bags may be excluded from the base cleaning rate and billed separately at a marked-up price. For a 20-person office with two restrooms, this item can represent an additional $150 to $300 per month. Explicitly verify what the contract includes in terms of consumables.
⚠️ Hidden Cost 3 — “On-Site” Supplements
Some providers offer an attractive base rate, then identify “additional needs” during the first visit — a floor requiring special treatment, a busier-than-expected restroom, equipment to clean not previously mentioned. These on-site additions are often billed at an uncapped hourly rate. Protection: as precise a scope of tasks as possible in the contract, and a written on-site quote before signing.
⚠️ Hidden Cost 4 — Uncapped Annual Price Adjustment
Many commercial cleaning contracts include an annual price adjustment clause indexed to CPI or “market conditions.” Without a contractual cap on this adjustment, a contract signed at $600/month can reach $800 in two years. Negotiate a cap on the annual adjustment (typically 3 to 5%) before signing.
⚠️ Hidden Cost 5 — Taxes Not Included in Displayed Rate
GST (5%) + QST (9.975%) total ≈14.975% on all commercial cleaning services in Quebec. Some providers display their rates before taxes to appear more competitive. A rate of $500 + taxes actually represents $574.88 all-in. Always ask for the all-in amount (taxes included) to compare quotes on an identical basis.

Frequently Asked Questions
How Much Does Commercial Cleaning Cost in Montreal?
To establish a budget, some businesses use an hourly rate or a per-square-foot price. As indicative benchmarks, published ranges are $25 to $45/hour per attendant for regular commercial maintenance, $45 to $85/hour or more for certain specialized work, and $0.015 to $0.030/sq ft per visit when square-foot billing applies.
These amounts are benchmarks and not a guaranteed price. The actual cost may vary depending on the premises, client requirements, schedules, accessibility, frequency and equipment needed. To know the price for your business, request a quote tailored to your situation.
Calculation example for a 10,000 sq ft space: As an example, a rate of $0.015 to $0.030/sq ft per visit would give a range of $150 to $300 per visit for 10,000 sq ft. This example is only to illustrate the calculation. It does not constitute a quote and should not be applied automatically to all contracts.
What factors influence the price?
📐 Square footage
Larger premises generally require more time, staff and equipment.
🔄 Frequency
Daily, weekly or other schedule may have a different price structure.
🧹 Cleaning level
Regular maintenance has different requirements than a deep clean or specialized intervention.
🏢 Premises type
Offices, retail, clinics, restaurants, condos, schools may have different requirements.
✨ Specialized services
Carpet, windows, floor stripping, disinfection may be added separately.
🕙 Schedule & access
Evening, night or special condition interventions may modify the cost.
Hourly rate or per-square-foot price?
The hourly rate can be practical when needs vary significantly from visit to visit. Per-square-foot pricing can be simpler for certain contracts where the area and scope are well-defined. In both cases, a good way to compare two offers is to verify what is actually included: frequency, tasks, supplies, equipment and contract conditions.
How much does specialized commercial cleaning cost?
Specialized work may cost more than regular maintenance when it requires additional equipment, products, time or methods. Window washing, carpet cleaning, floor stripping and waxing or certain disinfection interventions should generally be evaluated based on the site and the work requested.
