Patio Doors in Markham — Built for Ontario Living
A patio door is one of the most-used doors in any home — and one of the most visible. It connects your living space to the backyard, floods rooms with natural light, and frames the view. If your current patio door in Markham sticks, drafts, fogs between the panes or rattles on its track, it is quietly costing you comfort and energy every season.
Eurostar Windows & Doors has spent more than 30 years supplying and installing premium European patio doors in Markham and across the GTA. From sleek sliding patio doors to heavy-duty lift-and-slide systems that span an entire wall, we build each door to the exact size of your opening and install it to seal tight against Ontario's climate.
Whether you are renovating a kitchen in Unionville, opening up a family room in Berczy Village, or finishing a walk-out basement in Cornell, the right patio door transforms how the space feels and performs.
Sliding vs Lift-and-Slide Patio Doors
Choosing the right system is the most important decision, and it comes down to how large the opening is and how you want the door to operate.
Sliding patio doors
The classic choice: one or more panels glide along a track, so the door never swings into the room or onto the deck. Sliding patio doors are space-efficient, easy to operate every day, and pair beautifully with modern Markham homes. Our European sliders use multi-point locking and compression weatherstripping for a far tighter seal than the builder-grade sliders found in many GTA homes.
Lift-and-slide patio doors
For very large openings and premium builds, a lift-and-slide door is the standout. Turning the handle lifts the heavy panel slightly off its seals so even a huge, floor-to-ceiling panel glides with one finger; releasing the handle drops it back onto the seals for an airtight, weather-tight close. The result is an expansive, unobstructed wall of glass with exceptional energy performance — something ordinary patio doors simply cannot match.

Signs It Is Time to Replace Your Patio Door
A few clear signs tell most Markham homeowners their patio door has reached the end of its life: the panel is hard to slide or jumps its track, you feel a draft along the frame in winter, moisture or fog appears between the panes (a failed seal), the lock no longer engages properly, or condensation forms on the interior glass. Each of these means the door is leaking heat, money and security — and a modern European replacement solves them all at once.
Frequently Asked Questions
How much do patio doors cost in Markham?
Most Markham homeowners invest between $2,500 and $6,000 for a supplied-and-installed patio door, depending on size, whether it is a sliding or lift-and-slide system, the glass package and the frame. Large multi-panel and lift-and-slide systems sit at the upper end. Eurostar provides a free, itemized in-home quote so your price is clear before you commit.
What is the difference between sliding patio doors and lift-and-slide doors?
A sliding patio door glides on a track and is the classic, space-saving option. A lift-and-slide door uses heavier hardware that lifts the panel off its seals to glide effortlessly, then drops it back down to compress against the frame for an airtight, weather-tight close — ideal for very large openings and premium builds.
Are patio doors energy efficient enough for Markham winters?
Yes. Our European patio doors use multi-point locking, compression seals and Energy Star certified double or triple glazing, so they seal tightly against Markham's cold winters and reduce heat loss, drafts and condensation.
Do you install patio doors in all areas of Markham?
Yes — we serve all of Markham including Unionville, Cornell, Berczy Village, Wismer, Greensborough, Milliken and Thornhill, as well as the wider GTA.
What warranty comes with a patio door installation?
Every patio door installation in Markham includes a manufacturer product warranty and a 10-year labour warranty covering the workmanship.
