What interior demolition covers
Selective demolition inside an existing building, prepping the space for your renovation contractor without touching what's structural.
Kitchen gutting
Cabinets, countertops, flooring, and drywall removed down to studs and subfloor, ready for your renovation crew.
Basement strip-outs
Old finished basements gutted back to bare concrete and framing, including flooring, drop ceilings, and partition walls.
Whole-interior guts
Full-floor or whole-building interior strip-outs for larger renovations, additions, and change-of-use projects.
Tenant improvement strip-outs
Office and retail interior selective demolition ahead of a fit-out, coordinated around your build schedule.
What stays and what goes
Interior demolition is selective by design. We work from your renovation plans, or help you figure out the scope before your contractor is booked.
These typically come out as part of a standard interior gut.
Load-bearing walls and structural elements
These stay unless your renovation plans call for a structural change, in which case that work is scoped and engineered separately, not assumed.
Plumbing, electrical, and mechanical
We coordinate disconnection with your trades or the building's utilities before any wall or fixture comes out around them.
Salvageable fixtures
Tell us what you want kept or donated (cabinets, doors, fixtures) before we start and we'll set it aside instead of sending it to the bin.
Occupied buildings
Dust control and containment while the building stays in use
A lot of interior demolition happens while the rest of the house or building is still occupied. We section off the work area with poly containment and negative-air or dust-control measures where the job calls for it, and we protect the floors, stairwells, and hallways you’re using to move debris out. Ottawa winters add another wrinkle: with a January design temperature around -25C and thousands of heating degree-days each season, keeping dust and cold air contained to the work zone (not the rest of the house) is a real planning factor here, not an afterthought.
Interior demolition is almost always step one of a bigger renovation, not the whole project. We work directly with your general contractor or designer to sequence the strip-out so your trades can move in right behind us, and we haul and dispose of all debris as part of the job so the space is genuinely ready for the next crew, not just emptied out.
We look at the space (or your renovation drawings) and confirm what's coming out and what's staying.
2
Containment and protection
Poly containment, floor protection, and dust control go up before anything comes down.
3
Strip-out
Cabinetry, flooring, fixtures, drywall, and non-structural framing removed to the agreed scope.
4
Debris removal and clean handoff
All debris is hauled and disposed of, and the space is swept and ready for your renovation contractor.
Interior demolition pricing
Interior selective demolition across the Ottawa & Eastern Ontario region typically runs $8 to $21 per square foot depending on scope, finishes being removed, and containment requirements. Every job's scope and any workmanship terms are set out in your written quote.
Single room or kitchen gut
From $8/sq ft
Kitchen or bathroom strip-out
Cabinetry, flooring, fixtures removed
Debris hauled and disposed
Renovation projects almost always start the same way: something has to come out before something new can go in. Interior demolition is that first step, and getting it done cleanly, safely, and on schedule sets the tone for everything your renovation contractor does after.
Why interior demolition is its own trade
Interior demolition looks simple from the outside, but selective demolition inside an occupied or partially occupied building is a different job than tearing down a structure. It means knowing which walls carry load and which don't, protecting the parts of the building that aren't part of the scope, and controlling dust so the rest of the space stays livable or usable while the work happens. It's also a distinct trade category recognized by demolition industry associations, separate from full structural demolition.
Built around your renovation, not around us
We're not the ones designing your kitchen or finishing your basement. Our job is to clear the space to the scope your renovation contractor, designer, or your own plans call for, then get out of the way. That means working from your drawings or a clear scope walkthrough, coordinating timing so your trades can move in right behind us, and leaving the space swept and ready, not just torn apart.
Interior demolition FAQ
Does interior demolition include removing structural walls?
Not by default. A standard interior strip-out removes non-structural walls, cabinetry, flooring, and fixtures. Removing or altering a load-bearing wall is a separate, engineered scope of work and is only included if your renovation plans call for it and that's spelled out in your quote.
How long does an interior strip-out take?
It depends heavily on the size of the space and how much containment the job needs. A single kitchen or bathroom gut is typically much faster than a whole-basement or full-floor strip-out. We give a project-specific timeline as part of your written quote.
How do you control dust during interior demolition?
We seal off the work area with poly containment and use dust-control measures suited to the scope, and we protect the floors and pathways used to move debris out of the building. The goal is keeping dust and debris confined to the work zone.
Can I stay in the house or building during the work?
Often yes, especially for a single-room strip-out with proper containment. For larger whole-interior guts, it depends on the scope and how much of the building is affected. We'll talk through what makes sense for your specific project before work starts.
Do you remove the debris afterward?
Yes. Hauling and disposing of the debris is part of the job, so you're not left arranging a separate bin or haul-away after we've stripped the space.
Do I need a permit for interior demolition?
It depends on the scope. A building permit is generally required to demolish or relocate an existing building or structure in Ottawa, and some interior work triggers permit requirements depending on what's being altered. We can help you understand what your specific project needs, but confirming with the City is the homeowner's or contractor's responsibility.
