Windows and doors built for Calgary, not shipped to it.

Durabuilt has manufactured windows and doors in Alberta since 1988. Every unit we sell in Calgary is built in our own 280,000 square foot facility, delivered by our own trucks, installed by our own teams and serviced by the same company that made it. When something needs attention in year seven, there is no question about whose product it is or whose installation it was.

Windows for Renovation and New Builds in Calgary

Our sliding and casement windows share a universal frame design, which means you can combine them across a single elevation without mismatched sightlines. Every configuration is made to order, so replacement units fit the opening you have rather than the nearest standard size.

Doors for Renovation and New Builds in Calgary

A door is an assembly, not a slab. The frame, the threshold, the weatherstripping and the hardware determine whether it still closes properly after five Calgary winters. We build and install the whole assembly.

Where We Work in Calgary

Our Calgary team serves the full city and the surrounding communities, including Airdrie, Cochrane, Chestermere, Okotoks, Strathmore and High River.We work across every era of Calgary housing stock, and the era usually determines the approach:

Pre-1960s inner city — Altadore, Killarney, Mount Pleasant, Renfrew, Bridgeland. Original openings are frequently out of square and original flashing details are often absent. These are usually full-frame replacements, and stucco and brick exteriors make the finishing work a real part of the scope.

1960s to 1980s suburbs — Braeside, Thorncliffe, Dalhousie, Acadia. Large picture windows and aluminum-framed sliders from this era are typically the worst thermal performers in the house and the most immediately worth replacing.

1990s to 2000s — Tuscany, Evergreen, McKenzie Towne, Coventry Hills. First-generation vinyl is reaching end of life. Sealed unit fogging and failed balances are the usual triggers, and many of these are good retrofit candidates.

Recent builds and new construction — Builder-grade units in homes now ten to fifteen years old, plus new construction supply.

Basement developments — Legal basement suites and bedroom developments require openings that meet Alberta egress requirements. If the existing opening does not qualify, the work extends to cutting concrete and a new lintel. We will tell you that before quoting, not during installation.
