About GT Commercial Cleaning
Leave It Better
Three words that started on a driveway in Halton Hills — and now run every building we service.
Our story
Built From the Ground Up
GT was founded in 2021 by Dimitri Kalpakidis as a student-run mobile detailing company in Halton Hills. What began with one young entrepreneur and a commitment to doing things properly has grown into a trusted local team that has serviced more than 450 vehicles and earned over 130 five-star reviews.
Now, we're bringing that same level of care and accountability to commercial cleaning.
Operations
Meet Marco Amoroso
Operations Manager
Marco keeps GT running day to day — scheduling crews, managing client accounts, and making sure every visit hits the same standard. He's the direct point of contact for most clients, handling questions, check-ins and last-minute changes so nothing falls through the cracks.
With hands-on experience across detailing and commercial cleaning, Marco understands what facility managers and dealership owners actually need: reliable people, clear communication, and a job done right the first time.
The standard
One Standard: Leave It Better
"Leave It Better" has guided GT from the beginning. It means leaving every vehicle, facility, client relationship and community better than we found it. Whether we're cleaning an office, dealership, warehouse or industrial facility, the standard remains the same: show up, take pride in the work, and get it done right.
One team

Local People. Real Accountability.

One Standard: Leave It Better
Office, dealership, warehouse or industrial facility — the standard doesn't change: show up, take pride in the work, and get it done right.
Leave It Better.
It started as the promise behind every vehicle we detailed. Today, it's the standard behind every facility we clean and every business relationship we build.
