Professional Cleaning for Government and Institutional Properties That Cannot Afford Shortcuts.
Stratum Contracting & Co. delivers commercial cleaning, janitorial services, floor care, and facility maintenance for government buildings, school boards, hospitals, and institutional properties across the GTA.
A poorly maintained facility creates liability, fails inspections, and reflects on everyone inside it.
Procurement managers and facility directors face it constantly — inconsistent cleaning, missed schedules, substandard results, and contractors who disappear after winning the contract. Stratum exists to be the opposite. One point of contact, vetted cleaning crews, and documented results on every visit.
Built for institutional and government properties, not residential homes.
