Full-Service Commercial Cleaning & Janitorial Services in Toronto
Marathon Cleaning offers a full range of commercial cleaning and janitorial services across the GTA. Every facility is different, so every cleaning program we build is tailored — based on your square footage, foot traffic, industry requirements, and operating hours.
​
Our specialty is medical and dental office cleaning, where we follow strict infection-control protocols including hospital-grade disinfectants, colour-coded cleaning tools to prevent cross-contamination, and biohazard-compliant waste handling. We understand the standards medical facilities are held to, and we clean to meet them.
We also serve office buildings, condominiums, schools, daycares, gyms, retail spaces, dealerships, and industrial facilities — with eco-friendly green-certified products available across all service types. Whatever your facility, we'll build a cleaning plan around it.
