Good to know
Our own installers, not subcontractors. Many of them have years of experience with doors and windows in Quebec: they know the climate, the install details, and stay accountable to us. Our installation is guaranteed for 10 years.
Yes — free and no obligation. Describe your project online or call us: we can also visit to measure and advise on-site.
ABRiTEK windows (PVC and hybrid) — our main line — plus Concept and Dimensions. Entry doors from Dimensions and ABRiTEK. Patio doors from Novatech, ABRiTEK iNOVA and Decko. VP Stores blinds, and Altex depending on the project. We compare options with you for comfort, look and budget.
It is the line we lead with: PVC and hybrid, designed for Quebec’s climate, with one of the longest manufacturer warranties (up to 25 years per the official PDF). Concept and Dimensions remain available when they fit your project better.
In Quebec, some rooms must offer a compliant emergency exit. Clear opening size is regulated. We usually recommend a casement with an operable mullion, and egress hinges on some windows to increase the clear opening. An ACQ technical sheet is linked in our products section.
We work with Financeit to spread payments to fit your budget. For government programs like Rénoclimat, we can guide you; eligibility depends on your situation and current rules.
Outdoor and indoor condensation are different. Outside: good glazing keeps heat indoors, so the outer glass stays cold; on a clear humid night, fog forms — like dew on a car. It is not a defect, and it clears when the glass warms. Inside, a tighter window exchanges less air with outdoors, so humidity stays in the house. Condensation on the glass can be as frequent — if not more so — as with an older sash that “breathed.” Ventilating and controlling humidity (ideally around 30–50%) matter more than glass alone. If fog is between the panes, the sealed unit needs checking.
