Interior demolition, often called a strip-out, means gutting a space down to its structural bones without touching the building's exterior or load-bearing frame. That covers pulling drywall and ceilings, ripping out old flooring, tearing down non-structural partition walls, stripping kitchens and bathrooms, and disconnecting fixtures before electricians or plumbers cap the lines. It's the first phase on almost every condo renovation, office fit-out, and retail unit turnover in Toronto, and it's a different trade than full building demolition: smaller crews, more hand tools, and much more attention to protecting what stays behind.
We've listed 14 interior demolition and strip-out contractors working across Toronto. Before hiring, check that a contractor carries WSIB coverage and liability insurance, has a plan for asbestos testing if the building predates the 1990s, and can explain how they'll handle dust containment, debris chutes, and disposal in a condo or multi-tenant building where property management has rules about work hours and elevator use. Ask for a written scope that separates demolition from any hauling and disposal fees, since that's where quotes often diverge.
Our scoring weighs licensing and insurance, how a company handles hazardous materials and site protection, responsiveness to quote requests, and patterns in verified customer feedback.
