Questions from building owners

Do tenants have to leave during the installation?

No. We do not require occupants to vacate the property. We plan the work so people can keep living or working in the building.

How do I get a price for a whole building?

Book an on-site estimate. The price depends on the number of openings, their sizes, the products and the installation work, so we confirm it in a written quote after measuring.

Do you work with contractors and designers?

Yes. We supply and install for general contractors, construction companies, architects and designers, and our crews can work while yours are on site.

Can I see the windows and doors before I decide?

Yes. Visit the showroom at 1190 Rue Bégin, Saint-Laurent, before or after the in-home estimate.
