Disaster cleanup is a core part of our work. We respond to property losses that require more than routine janitorial cleaning, including situations where water, smoke, sewage, mold, contamination, or other damage can affect the safety and usability of a building.

We provide water and flood damage cleanup, fire and smoke cleanup, sewer backup cleanup, and structural drying. Our team also provides mold removal and decontamination, vandalism cleanup, odor control, and emergency cleaning.

These services are different from ordinary janitorial cleaning because the work may need to begin quickly and respond to conditions created by a specific loss. Depending on the situation, the project can require water extraction, structural drying, contamination control, odor treatment, specialized equipment, or restoration-related cleaning. We can coordinate the cleanup around the conditions found on site, with the objective of stabilizing affected areas, cleaning and recovering what can be saved, limiting secondary damage, and helping the property move toward normal use as efficiently as possible.

We provide emergency cleaning and disaster-response support 24 hours a day, 7 days a week. Urgent calls may involve water or flood damage, sewer backups, fire and smoke damage, contamination, or other situations where waiting can allow damage to spread or make cleanup more difficult.

We keep multiple teams on standby for emergency work, with equipment in stock and ready to deploy. This allows us to respond to residential properties as well as larger commercial, industrial, and institutional losses.

For immediate assistance, call 514-830-6787 and press #1 for emergency response. Providing clear information about the type of damage, the property, and the affected area helps our team understand the situation and organize the appropriate response.

We work with clients across four main property sectors: commercial, industrial, institutional, and residential. This includes private homeowners as well as organizations responsible for larger, more complex facilities.

Commercial work can include offices, retail environments, construction sites, and multi-residential properties. Industrial projects may involve warehouses, production areas, equipment, or large interior spaces requiring specialized cleaning. Institutional experience includes hospitals and healthcare facilities, along with other public or organizational properties where cleaning requirements can be especially demanding.

Our project history includes construction cleanup, warehouse work, hospital flood emergencies, fire cleanup in multi-unit residential properties, and specialized cleaning for large facilities. This range allows us to adapt our workforce, equipment, and cleaning approach to the type and scale of the property involved.

Clients choose us for our long-term experience, 24/7 emergency availability, and ability to handle demanding cleanup projects. We have operated since 1990 and have a large team of qualified technicians serving residential, commercial, industrial, and institutional properties.

Our disaster experience includes water damage, fire and smoke damage, sewer backups, mold, vandalism, and other situations requiring specialized equipment or restoration-related cleaning rather than ordinary janitorial service.

We also have experience working with the insurance industry. Our project history demonstrates our ability to mobilize for large assignments, including post-construction cleaning of a 40-storey, 500,000-square-foot building where more than 100 qualified technicians worked on the project.
