Demolition Services in Quebec

Gas, electricity and water must be professionally disconnected (capped) by the utility or a licensed trade before demolition begins — not just switched off. This is a safety-critical step; a reputable demolition contractor coordinates it and won't start until it's confirmed.

A room strip-out is often a day or two; a full house gut a few days to a week; a full structural demolition one to two weeks including site clearance. Asbestos removal, permits and utility disconnections add lead time before work can even start.

For anything structural — removing walls, demolishing a building or a large extension — yes, almost always (see country notes). Interior soft-strip of non-structural elements often doesn't, but check locally. Utilities must be safely disconnected first, and neighbours may need notifying.

A soft strip (or strip-out) removes internal non-structural items — fixtures, fittings, linings, services — leaving the structure. Full demolition takes down the structure itself. Renovations usually need a strip-out; only rebuilds or clearances need structural demolition, which is far more involved and regulated.

Debris goes to licensed waste facilities, with much of it (concrete, metal, timber) sorted for recycling. Disposal and tip fees are a big part of the cost, especially where landfill charges are high. Ask whether disposal is included in the quote and where the waste goes.

Structural demolition requires a municipal permit and usually a designated-substances (asbestos) survey on older buildings. Interior non-structural strip-out may not, but check your municipality — the contractor should manage permitting and surveys.
