Frequently Asked Questions
What is included in a commercial janitorial cleaning contract?
Every contract is scoped to the specific facility. A standard contract covers routine cleaning of common areas, washrooms, floors, and high-touch surfaces on a defined schedule. Additional services - deep cleaning, carpet cleaning, floor stripping and waxing, window cleaning - can be added as needed. SMI provides a detailed scope of work before any contract begins.
How often will SMI clean our facility?
Frequency depends on the size of your facility, the nature of your operations, and your budget. Most commercial clients are serviced nightly or several times per week. High-traffic facilities or those with specific hygiene requirements may require daily or multiple-daily service. SMI will recommend an appropriate frequency following the on-site assessment.
Can you clean outside of business hours?
Yes. Most SMI commercial janitorial contracts are performed after hours, early mornings, or on weekends to avoid disrupting operations. We work around your schedule, not the other way around.
Do you provide the cleaning supplies and equipment?
Yes. SMI supplies all cleaning products, equipment, and if requested, can also provide all necessary consumables required to perform the contracted scope of work. All products are WHMIS-compliant and eco-friendly.
Can SMI handle janitorial cleaning for multiple locations?
Yes. SMI manages multi-location cleaning contracts for property management companies and businesses operating across the GTA. A single point of contact manages all locations and ensures consistent service standards across your portfolio.
