Before you sign with a commercial cleaning company in London
Ask the company for:
- A certificate of insurance naming your business, showing commercial general liability (commonly $2 million or more per occurrence) and a janitorial bond, plus a clearance certificate from the WSIB showing their workers' compensation account is in good standing.
- A price that fits the work. In London, a 10,000 sq ft office cleaned three times a week runs about $1,400 CAD a month. A bid far below that usually means fewer hours on site, so ask for the crew size and hours per visit.
- How keys, alarm codes and after-hours access are handled, and who on the crew holds them.
- Two references from buildings like yours in the London area. Call both.

Frequently asked questions
How much does commercial cleaning cost in London?
It depends on size and how often it's cleaned. In London, a 2,500 square foot office cleaned once a week runs about $425 a month, and a 10,000 square foot office cleaned five times a week about $2,250, based on the local median cleaner wage of $19.00 an hour. Medical offices and gyms cost more per square foot, and churches and warehouses cost less. Prices are in Canadian dollars, before sales tax.
Is janitorial service the same as commercial cleaning?
Mostly. Janitorial service usually means the routine cleaning done every visit: trash, restrooms, dusting and floors. Commercial cleaning also covers periodic and specialty work such as floor refinishing, carpet extraction and window washing. Most commercial cleaning companies in London do both.
