Any questions?

If you can’t find yours, give us a call!

How much does an extension in Montreal cost?

An addition generally costs between $250 and $350 per sq. ft., depending on the materials used, the scope of the work and the complexity of the structure. We provide a clear estimate within 48 hours of our free consultation visit, with no hidden costs.

Do I have to leave my home during the work?

No, we fit the building site with effective dust and noise protection. Thanks to daily cleaning, you can live as normal in your home, even when adding a storey or a major rear extension.

Is Davana arranging the necessary permits?

Yes, we take care of all municipal procedures related to your extension or modification: building permits, inspections and regulatory compliance. That way, you avoid administrative stress and enjoy peace of mind during your project.

Can the project be adjusted during construction?

Of course. With our “time and materials” model, every change you make (size, materials, finish) is quickly taken into account. We adjust the next invoice without financial penalties or significant site delays.

How long does an extension take?

Depending on size, a storey addition takes around 3 to 4 months, a rear extension or garage between 6 and 8 weeks. Each project is meticulously planned with you, and together we validate the weekly progress to guarantee the promised deadlines.
