Keystone Facility Services
Quote

Commercial cleaning services for professional offices.

Keystone focuses on recurring cleaning for professional workplaces: offices, clinics, advisory firms, real estate offices, mortgage and insurance offices, and similar owner-operated spaces.

Choose the service that matches your facility.

Every quote starts with a walkthrough and ends with a written scope, an owner accountable for it, and photo-verified completion.

Honest fit

Keystone is deliberately not for everyone.

A narrow service model is what makes the reliability promises keepable. Here is the honest line.

A strong fit

  • Owner-operated professional offices between roughly 1,500 and 5,000 square feet
  • Accounting, law, mortgage, insurance, real estate, consulting, and similar practices
  • Dental, medical, optometry, and therapy clinics that need documented boundaries
  • Teams of about 5 to 25 staff that need recurring after-hours service
  • Offices across Toronto, Vaughan, Mississauga, Brampton, Markham, Richmond Hill, and surrounding GTA business communities
  • Managers who want a written scope and proof of completion, not a sales pitch

Not the right provider

  • Homes and residential condos. Keystone is commercial only
  • Large facilities that need a day-porter team or industrial cleaning crews
  • One-time house-style cleans with no recurring schedule (post-construction is the exception)
  • Buyers shopping for the lowest possible price at any standard

If that last line stung, it was meant kindly: a quote built on a written scope is rarely the cheapest number in the pile; it is the one that still describes the service six months in.

Still weighing options? Start with how pricing works or how often offices actually need cleaning.
