Doors & Windows in Montreal

Replacing doors and windows for airtightness, efficiency and light.

At Construction Hibou, well-installed doors and windows improve the comfort, efficiency and look of your home, across Greater Montreal.

A new window is only as good as its installation: without careful sealing and insulation around the frame, air and water get in. We replace doors and windows, and create new openings when needed, with the flashing and insulation required. As an RBQ-licensed general contractor, this service is part of our construction work.

Doors and windows are where a home meets the weather, so small gaps add up to real drafts and heat loss over a winter. Done right, a replacement pays you back in comfort every single day, and gives the facade a noticeable lift.

Budget

How much does door and window replacement cost in Montreal?

For openings, the number and the type lead the budget. Here's what moves it:

• The number of openings — the more doors and windows you replace, the bigger the project.
• The type and quality — the model, glazing and efficiency level move the price.
• New openings — creating or enlarging an opening adds structural work.
• Finishing — interior and exterior casings and weatherproofing details add to the project.

Every project is quoted after a free consultation.

Timeline

How long does replacing doors and windows take

Custom doors and windows are manufactured before anything gets installed. Here's what affects the timeline:

• The number of openings — replacing a few windows is faster than the whole home.
• Manufacturing lead times — custom doors and windows take time to produce.
• New openings — structural work adds a step to the schedule.
• The weather — replacing openings depends in part on the weather.

We give you a realistic schedule up front and keep you informed through to the end.

Frequently asked questions

Doors and windows: your questions

Do you replace both doors and windows?

Yes. We replace windows, exterior doors and interior doors, and we install patio doors. We can coordinate it all in a single project.

Why does installation matter so much?

Because an efficient window that's poorly installed still lets air and water through. We take care with the flashing, insulation and caulking around the frame, where airtightness and energy efficiency are decided.

Can you create a new opening?

Yes. We can enlarge an existing opening or create a new one, with the lintel and structural reinforcement required to do it safely.

Do new windows improve efficiency?

Yes. Recent windows, well insulated and well installed, reduce heat loss and drafts, which improves the home's comfort and energy efficiency.
