Basements
Transforming your basement is like adding a whole new floor to your house without expanding the foundation. You gain living space, improve your family’s comfort, and increase your property’s value. In Montreal, more and more people are renovating their basements to create a family room, a home office, a playroom, a home theater, or even a rental unit for extra income.
No matter the purpose, we can tailor your project to your space and budget. We do basement renovations all over Montreal, whether it’s a raw space to finish or an old basement to completely modernize.
Average price to renovate a basement in Montreal
For a full finish of a basement without a bathroom or kitchen, starting from concrete, the price usually ranges between $35,000 and $50,000, depending on the size and specifics of the space. This price includes drywall partitions, full insulation of exterior walls, vinyl plank flooring with underlay, recessed ceiling lights, electric baseboard heaters, painting, moldings, and basic plumbing (e.g., drainage, water supply for a future bathroom).

To consider:
A basement is often humid and prone to water infiltration. Before thinking about the nice finishes, you need to make sure the envelope is watertight: waterproof membrane, a good French drain, submersible pump if necessary.
Floors must be adapted to moisture. Avoid materials like hardwood or regular carpets in the basement. Waterproof floating floors, vinyl, or ceramic are safer choices.
Ceiling height is important. If you have ducts or beams lowering the height, it can affect the perception of the space—or even compliance if you plan to make it a rental unit.
