One more living space, done in the right order — moisture, insulation, then finishes.
At Construction Hibou, a basement renovation is a turnkey project: one team handles moisture control, insulation, framing and finishing, across Greater Montreal.
A basement is often the cheapest living space to gain in a home — as long as the basement finishing is done in the right order. Moisture control and proper insulation come before the nice finishes, or the problems come back. As a general contractor licensed by the RBQ (5798-4619-01), we carry out every step to code and obtain permits when required. This service is part of our residential renovation work.
Basements finished by our team, from storage to a wine cellar.
A successful basement finishing starts below the surface — here's everything we take on.
We assess moisture and signs of water intrusion first. Vapour barriers, the right materials and careful details keep the basement healthy and dry over time.
Foundation walls and cavities insulated to code, for a more comfortable, quieter and more energy-efficient space.
Framing, partitions, ceilings and doors that turn a raw space into finished, functional rooms.
Cabinetry, closets and built-in storage that make the most of a basement, often the most underused space in the home.
Adding a bathroom, a compliant bedroom or a family room, with the windows the Code requires.
Flooring, paint, mouldings and finishes, with a site protected and cleaned every evening.
From the first meeting to handover — organized and transparent.
We assess your project and give you a clear, detailed quote.
Project planning, budget planning and scheduling — with you.
Our team delivers the work properly and on time.
Final walkthrough with you, clean site, impeccable result.
In a basement, the moisture situation changes everything about the budget. Here's what moves it:
• The scope of work — a simple family room and a full layout with a bathroom aren't the same investment.
• Moisture conditions — waterproofing or drainage work, if needed, adds to the project.
• Adding a bathroom or kitchen — the plumbing is a significant share of the cost.
• Materials and finishes — flooring, lighting, storage and millwork cover a wide price range.
• The layout — partitioning several rooms takes more work than one open space.
Every project is quoted after a free consultation.
Correcting moisture before finishing adds a step you can't skip. Here's what affects the timeline:
• The scope of work — an open room finishes faster than a multi-room layout.
• Moisture work — correcting a water issue adds a step before finishing.
• Adding plumbing — a basement bathroom extends the schedule.
• Material lead times — flooring, doors and custom cabinetry have a supply lead time.
We give you a realistic schedule at the design stage and keep you informed through to handover.
Moisture control is the first step of any basement project. We assess signs of water intrusion and dampness before starting, address the source when needed, and use the right vapour barriers and materials to keep the space healthy and dry.
A permit may be required depending on your municipality and the scope, especially if you add a bedroom, a bathroom or modify the electrical. As an RBQ-licensed contractor, we check your city's requirements and obtain the necessary permits before we start.
Yes. We insulate the foundation walls and cavities to code, which makes the basement more comfortable and more energy-efficient. Good insulation, combined with moisture control, is essential for a livable basement.
Yes. You can add a bedroom, an office, a family room or a bathroom in the basement. A bedroom requires a compliant egress window, and a bathroom requires adding the necessary plumbing. We carry out these additions to Code.
It depends on the scope and the state of the basement. A simple finish takes less time than a full layout with a bathroom or kitchen. Exact timelines are confirmed at the design stage, and we give you a schedule before the work begins.
