Custom basement finishing in Pierrefonds and Greater Montréal

Custom basement finishing turns an often underused space into a high-end living area — home theatre room, bar, wine cellar, library or game room — with built-in cabinetry designed for how you actually use it. At Dilamco, in Pierrefonds and across Greater Montréal, we handle the design, controlled fabrication at our partner factory and installation, from plan to finish.

A basement designed as a true living space

A basement gains value when the cabinetry is integrated from the start: storage, wall units, a bar or a theatre planned with the room, not added afterward.

A clear process from design to installation

A single partner to frame decisions, coordinate the trades and reduce surprises on site.

1
Design
Analysis of the space, the constraints (height, columns, mechanical) and zone planning.
2
Materials
Selection of components and finishes suited to humidity and the real use of a basement.
3
Fabrication
Controlled production of the modules (theatre, bar, cellar, storage) with stable standards.
4
Installation
Precise fitting, clean alignments and finishes verified on site.

Materials chosen for the reality of a basement

A basement imposes its constraints: humidity, temperature swings and technical access. The choice of materials and structure matters as much as the look.

  • Moisture resistance Components and finishes selected to better tolerate a basement environment.
  • Durable structure Birch plywood and solid wood where load and stability matter.
  • Clean integration Wiring, equipment and mechanical access concealed for a consistent finish.

FAQ - basement finishing

Clear answers to the most common questions before starting a basement project.

The price of custom basement finishing varies a lot depending on the floor area to cover and the spaces you want: a home theatre room, a bar, a wine cellar, a library or storage don't involve the same level of millwork or coordination. Add to that the materials and finishes chosen, the details suited to a basement environment (moisture, height management), and the extent of coordination if other trades are involved. Rather than a generic price, we provide a precise estimate once the project is scoped with you — real uses, priorities and finish level — for a clear budget before you commit.

A “home theatre” often refers to the audio-video equipment (speakers, receiver). A custom home theatre room is the finishing of the room itself: riser, panels, equipment storage and built-in cabinetry. That is what we design and fabricate.

Yes. We are based in Pierrefonds-Roxboro and build custom basement finishing throughout the West Island, Montréal, Laval and Greater Montréal.

We select materials and finishes suited to a basement environment and take care with construction details to limit warping and humidity-related issues.
