Energy-Efficient Casement Windows in Markham
Eurostar Windows & Doors serves homeowners throughout Markham, Unionville, Milliken and Thornhill with premium European casement windows. Backed by 30+ years of experience and a 5.0 rating from more than 60 verified reviews, we help Markham families replace drafty, dated windows with airtight, energy-saving units built to handle Ontario's temperature extremes.
Casement windows are hinged at the side and open outward with a smooth crank. When closed, the sash presses tightly against the frame on all four sides — creating one of the most weather-tight seals of any window style. For Markham's cold winters and humid summers, that means lower energy bills, fewer drafts and less condensation year-round.
Why Markham Homeowners Choose Casement
- Airtight four-sided seal for excellent energy efficiency and comfort.
- Energy Star certified glass tuned for Ontario's climate.
- Maximum ventilation and clear views — the sash opens fully.
- Multi-point locking hardware for enhanced home security.
- Easy interior cleaning of both sides of the glass.
Each window is custom-manufactured to your opening and finished in the colour and hardware that match your home, whether it is an established Unionville property or a newer build in northern Markham.
Full-Service Local Installation
Our certified installers handle every step — careful removal, precise fitting, weather-tight sealing, interior and exterior trim, and complete clean-up — and most Markham homes are finished within one to three days. We manage any required permits and register your lifetime product and 10-year labour warranty on completion. From your first free in-home consultation through the final walkthrough, you get honest guidance and a clean, professional result.
Casement vs Double-Hung for Markham Homes
Double-hung windows are a common sight on Markham's traditional facades, and they have their place. But when energy efficiency is the priority, casement windows win on sealing. A double-hung unit has a movable meeting rail and relies on weatherstripping that wears; a casement compresses tight against the frame on all sides. For north-facing rooms, exposed corner lots and any home fighting winter drafts, that difference shows up on your heating bill. Many Markham homeowners keep double-hung windows on the front for a classic look and switch to casements on the sides and rear where efficiency and ventilation matter most.
Whichever direction you lean, we help you weigh the trade-offs honestly during the in-home consultation rather than pushing a single product.

- Double or triple-pane glazing with low-E coatings and argon fill.
