Planning a Kitchen Renovation in an Older Montreal Home: What to Sort Out Before Demolition

Montreal has a housing stock unlike most North American cities. Plateau triplexes, Rosemont duplexes, postwar bungalows in Saint Leonard, and century homes in NDG all share one thing: the kitchen was designed for a household that cooked differently, stored less, and owned fewer appliances. That is why the kitchen is usually the first room people want to change, and why it is the room most likely to reveal surprises once the walls open up.

Kitchen and bath projects make up roughly a third of what homeowners spend on discretionary improvements, according to research on how remodeling dollars get allocated. It is a serious investment. The projects that go smoothly are almost always the ones where the unglamorous decisions got made before anyone picked a backsplash.

Find Out What Is Actually Behind the Wall

In a building from the 1920s or 1930s, the kitchen wall you want to remove may be carrying load, or it may be hiding a cast iron stack, or both. Older Montreal properties often have knob and tube remnants, undersized panels, and galvanized supply lines that nobody thought about because the kitchen worked well enough.

An exploratory opening before the design is finalized costs very little and changes everything downstream. It is far cheaper to move a proposed island two feet on paper than to discover mid project that the drain cannot be relocated without cutting into the joists.

Understand the Permit and Licence Side Early

Quebec has its own rules, and they are not optional. Structural changes, plumbing relocation, and electrical work all fall under provincial requirements, and contractors performing this work need to hold a valid RBQ licence. In a divided co ownership, the syndicate may also need to approve anything that touches common elements, which in many Montreal buildings includes the plumbing stacks running through the kitchen wall.

Boroughs handle permits differently as well. What clears quickly in Ahuntsic may take longer in a heritage sector of the Plateau. Ask about the timeline before committing to a start date, not after.

Sequence the Work Around the Quebec Calendar

The renovation season here is shaped by winter. If a project involves anything exterior, a new window opening, a rear balcony, or a service entrance, that work has to land between roughly April and November. Interior kitchen work can run year round, but material deliveries slow in the deep winter months and custom cabinetry lead times stretch when everyone books at the same time in spring.

The practical move is to order long lead items first and schedule demolition around the delivery date rather than the other way around. A kitchen sitting gutted for six weeks waiting on cabinets is the most common source of frustration in this trade, and it is entirely avoidable.

Do Not Skip Ventilation and Humidity

Older Montreal homes are tight in some places and leaky in others, and kitchens generate a lot of moisture. A properly ducted range hood that exhausts outside, not a recirculating unit, is worth more to the long term health of the room than an upgraded countertop. The same attention to efficiency in residential mechanical systems that applies to heating and cooling applies here. Moisture that has nowhere to go ends up in the cabinets and the drywall.

Budget for the Third of the Project Nobody Photographs

Homeowners plan for cabinets, counters, flooring, and appliances. The budget line that gets underestimated is everything behind them: rewiring, replumbing, subfloor levelling, and drywall repair where old plaster meets new construction. In an older property, that work can account for a meaningful share of the total.

Set aside a contingency and treat it as spent. If it is not needed, that is a good outcome, not a windfall to redirect into a nicer faucet halfway through.

Choose the Team Before the Finishes

The most common mistake is choosing materials first and looking for someone to install them second. A crew that handles kitchen renovations in Montreal regularly will flag the structural and mechanical issues during the design phase, when changes are still free, rather than during demolition when they are not.

Get the assessment done, understand what the building will and will not allow, then choose finishes inside those constraints. Kitchens that get planned in that order tend to finish on schedule and stay looking right a decade later.
