Bespokefenestration,made to measure.
Aluminum windows and doors fabricated in Quebec and installed by our own teams. Walls of glass with frames you barely see, engineered for a Canadian winter.
Alumalco
Larger glass. Slimmer frames. More sky in every room.
Our opening, sliding and folding systems combine European hardware with aluminum profiles strong enough for oversized formats. Every piece is custom-made, tested against the harshest weather, and installed by people who do only this.

Homeowners
“Bought a home and replaced all windows and doors. Shopped a lot around but pricing and quality was the best at Alumalco. I had already 6 people coming over to ask about my windows and doors. You brought my house to another level.”
“Excellent experience from start to finish for our large Lift and Slide door. Beautiful product, and excellent service. Would definitely use again.”
“The doors are stunning, and the service, stellar! We couldn't be happier with the look and incredible quality, and couldn't ask for a better team, from choosing the product to installation.”
“We hired Alumalco to replace our aging 16 ft tall windows. The result looks awesome. The installers did not leave the job until everything was 100% done.”
“Amazing company with amazing people. This is probably the best quality you can get in Canada. Two large Lift and Slide patio doors and a large fixed window. We are amazed by the outcome.”
“From the sales rep to the men installing the doors, all of them were knowledgeable, professional and provided quality service. Quick, efficient and thorough.”
“Respectful, experienced and dedicated people to have work on your home. The product is exceptional and the service is outstanding.”
“Not only is the finished product of high quality, modern and chic, but the team we worked with was very professional. We love our new windows and our wonderful doors!”
