Interior demolition and strip-out covers the gut work that happens before a renovation or fit-out can start: tearing out drywall, ceilings, flooring, kitchens, bathrooms, and non-structural partitions, then clearing the debris so trades can rebuild. It's different from full building demolition because the shell usually stays standing, walls and mechanical systems may need to stay live, and crews often work inside occupied buildings or multi-unit properties where dust control, noise limits, and scheduling around neighbours actually matter. We've found 15 contractors in Mississauga offering this service.
What to look for before you hire
Ask whether the crew handles hazardous material screening (older Mississauga buildings can still have asbestos in tile, plaster, or pipe insulation) and whether they pull the right permits for your municipality. Get clarity on debris disposal and recycling, since dumping fees add up fast on larger strip-outs. Check that they carry liability insurance and WSIB coverage, and ask how they protect adjacent finished spaces, elevators, and shared corridors if you're in a commercial or condo building. A written scope with a fixed price or clear per-square-foot rate beats a vague verbal quote every time.
How we score contractors
Our ranking weighs licensing and insurance, safety practices around hazardous materials, responsiveness, pricing transparency, and how consistently a contractor's past work has held up based on the details we could verify. The full breakdown of how we weigh and check each factor is on our methodology page.
