Commercial Cleaning Service in Mississauga
KastKleen is a family-owned commercial cleaning company serving Mississauga and the GTA. We provide reliable cleaning for offices, retail spaces, warehouses, and recreational facilities with flexible scheduling. WHMIS-certified, fully insured, and bonded, we deliver quality service with minimal disruption to your business.
Who We Are
A Trusted Commercial Cleaning Partner in Mississauga
KastKleen was officially registered in December 2024, but the experience behind it goes back much further. Our family has worked in the cleaning industry since the early 1950s, and KastKleen was created to bring that same standard of professional cleaning to Mississauga businesses under a dedicated commercial cleaning brand.
That background shapes how we operate today: consistent crews, clear communication, and a hands-on approach where the details actually get checked, not just listed on a service sheet.

Why Us?
Why Mississauga Businesses Choose KastKleen
Real industry experience: Our family’s cleaning background goes back to the 1950s. That’s decades of knowing what actually works on commercial floors, fixtures, and finishes — not guesswork.
Scheduling built around your hours. We default to overnight and after-hours cleaning specifically to avoid disrupting your staff, customers, or members.
Fully credentialed. WHMIS certified, insured, and bonded, so your property and your liability are covered.
Eco-conscious where it counts. We use eco-friendly, environmentally responsible cleaning products wherever possible, so your space stays spotless without harsh chemical residue or strong odours.

Why Us?
Emergency Cleaning Service - Including After-Hours
Our office is open Monday to Friday, 8:00 AM to 5:00 PM, but our cleaning crews work around your business, not ours. Most cleaning happens between 6:00 PM and 6:00 AM so your operations, staff, and customers are never interrupted.
We also offer emergency commercial cleaning in Mississauga for situations that can’t wait for a scheduled visit: a burst pipe, a spill in a retail space before opening, a post-event mess, or a facility that needs to be ready sooner than planned. Call our office and we’ll work out the fastest realistic turnaround for your situation.
