Commercial properties are just as at risk of flooding as residential properties across the Greater Toronto Area. To protect your equipment, inventory, and valuables, it’s important to make water damage remediation and mold removal in Toronto a priority. When you find your basement flooded or water damage in your commercial property, don’t hesitate.

What Needs to be Addressed After Water Damage?

Electrical Risks

Flooding poses significant safety hazards, especially to your building’s electrical and mechanical systems. Water can reach HVAC systems, fuse boxes, and data equipment in the basement, putting your property and team at risk. Never attempt to enter a flooded basement without professional help.

Mold Removal

Flooded areas that are not dried thoroughly within 24 to 48 hours are prime breeding grounds for mold. Basements are already dark and humid environments, so when water is added to the equation, mold growth can escalate quickly. Left untreated, it can spread throughout the building, affecting air quality and putting staff and visitors at risk.

Professional mold removal in Toronto ensures that all hidden and visible growth is eradicated safely and in compliance with health and safety standards.

Property Damage

Furniture, inventory, supplies, or archived documents stored in a basement can be permanently damaged by floodwater. Even when items appear dry on the surface, moisture can linger and cause deterioration or microbial growth, leading to additional expenses.

Reconstruction

In some cases, structural repairs or reconstruction are necessary following significant water damage in Toronto. Our team at Canada’s Restoration Services is equipped to handle everything from minor repairs to full-scale rebuilds, helping restore your commercial space safely and quickly.
