Interior demolition, often called strip-out, is the gutting phase that happens before a fit-out or a full renovation begins. Crews strip drywall, flooring, ceiling tiles, partition walls, old fixtures, and sometimes mechanical, electrical, and plumbing (MEP) systems down to the shell, while leaving the building's structure, envelope, and shared services intact. It covers everything from clearing a single retail unit or restaurant in a Mississauga plaza to gutting a full floor of office space in an industrial-commercial building near Airport Corporate Centre or Meadowvale. We've listed 10 contractors in Mississauga who take on this kind of work.
Because strip-out happens inside occupied or shared buildings, the job carries risks that don't come up with a standalone teardown: dust and noise affecting neighbouring tenants, hidden hazardous materials like asbestos-containing ceiling tiles or vermiculite insulation in older buildings, and utilities that need to be isolated safely before anyone starts cutting into walls. A buyer should ask about a few specific things before signing: whether the crew carries their own dust containment and negative-air setup, whether they handle hazardous material testing and abatement in-house or sub it out, how debris is separated and disposed of (recyclable material like metal studs and clean concrete versus mixed waste), and what their plan is for working around building hours, freight elevators, and property management rules. A written scope that spells out what stays and what goes, plus a fixed price or clear unit rates, avoids most disputes once walls start coming down.
Our scoring weighs licensing and insurance, safety record, response time, and how consistently a contractor delivers on the scope and timeline they quote, so you can compare these 10 options on more than just price.
