Whole-Home & Gut Renovation in toronto

A whole-home or gut renovation strips a house back to its studs and subfloor, sometimes further, and rebuilds it around a new layout. That can mean removing interior walls to open up a century home in Riverdale, redoing every system in a Scarborough bungalow, or gutting a semi in the Junction down to the brick and starting over with new plumbing, wiring, insulation, and mechanicals. It's a different scale of project from a kitchen or bathroom job: permits are almost always required, structural engineering is often involved if load-bearing walls move, and the timeline usually runs from several months to over a year depending on the size of the house and how much the scope shifts once walls come down.

Because so much is hidden until demolition starts, the contractor's judgment matters as much as their finish carpentry. Look for a company that pulls its own permits, works with a licensed structural engineer when needed, carries proper insurance and WSIB coverage, and gives you a detailed contract with an allowance schedule rather than a vague lump sum. Ask how they handle surprises like knob-and-tube wiring, asbestos, or a foundation issue found mid-demo, since almost every gut job hits at least one of these.
