What affects your price
Every home is different, so we price each project individually after a free in-home consultation — no commissioned salespeople, no hidden fees. You'll receive a detailed written quote within 24–48 hours. The main factors that shape your investment:
- Number of windows and their sizes — larger and custom shapes cost more per opening
- Frame material: vinyl is the most economical, aluminum and wood finishes are premium
- Glass package: double vs. triple pane, Low-E coatings, and argon fill
- Installation type: retrofit inserts vs. full brick-to-brick replacement
- Structural work: new openings, enlargements, or sill replacement add scope
Common questions
How long does window replacement take?
Most window replacement projects are completed in 1–2 days. Larger projects or those involving new openings and structural work can take longer — we confirm the timeline in your written quote.
Do I need to replace my blinds or shutters?
No. We retrofit your existing shutters and blinds to your new windows and re-install them for you — you don’t need to buy new window coverings.
Are your windows Energy Star certified?
Yes. We offer Energy Star certified windows that meet or exceed Canadian energy-efficiency standards, which helps reduce heating and cooling costs year-round.
What warranty comes with new windows?
Our windows carry manufacturer warranties ranging from 25 years to lifetime, and every installation is backed by our own workmanship warranty.
