St. Catharines, Ontario · Commercial Cleaning Specialists
Professional commercial cleaning and recurring janitorial services for St. Catharines offices, clinics, restaurants, gyms, dealerships, industrial facilities and more. Better equipment. Better cleaners. Better results.
One accountable cleaning partner for your entire facility.
From Downtown St. Catharines and the Ontario Street business corridor to Port Dalhousie, Merritton and the Fourth Avenue commercial district, businesses need dependable janitorial teams—not constant reminders.
Niagara Regional Cleaning Inc. provides structured, recurring commercial cleaning programs tailored to the layout, traffic and hours of each property. We handle professional offices, healthcare workplaces, restaurants, showrooms, fitness facilities, industrial spaces and shared buildings.
We coordinate keys and alarms, document the scope, use professional equipment and follow up on quality. Our cleaners pay attention to the details that often get missed: washroom fixtures, vents, baseboards, edges, glass and cobwebs.
