Awning Windows

Awning windows are an energy-efficient and cost-effective window option for your home in Newmarket. These windows swing outward, allowing for enhanced air circulation while preventing rain and outdoor debris from entering the home. In Newmarket, awning windows are a popular window choice for the kitchen.


Bay Windows

Bay windows are a truly stunning feature for any home in Newmarket. A traditional bay window features three panels extending outwards on an exterior wall. The front panel is flat and parallel to the wall, with angled side panels on the left and right sides. The bright and beautiful alcoves that bay windows create can be enjoyed as a cozy reading nook or decorative green space.


Bow Windows

Bow windows are similar to bay windows by extending outwards from exterior walls, but incorporating four or more panels. The more window panels, the rounder the curve, providing softer angles and an attractive curb appeal for any home in Newmarket.


Casement Windows

Casement windows are a common and practical window choice in Newmarket due to their tight seal against cold and humid weather conditions. Casement windows will improve air circulation in your home while creating a sleek look when paired with modern window treatments.


Custom Windows

Whether you live in an older home or out in the countryside surrounding Newmarket, our team will provide you with the best possible range of window options, no matter the age or specifications of your home. As each window is tailored to accommodate any window shape or size, our expert tradespeople will ensure all windows fit seamlessly into your home.


Double Hung Windows

A double hung window will allow you to manage where air flow originates from in your home. As the two window sashes open from either the top, the bottom, or from both directions, a double hung window improves air circulation more efficiently than a single hung window.


Single Hung Windows

Single hung windows are easy to clean and operate, remaining a classic and popular window choice in Newmarket. The single hung window has two sashes, with the top sash fixed in place and the bottom sash able to slide up and down with minimal effort. Installing single hung windows will reduce your energy costs and increase your home’s curb appeal.


Slider Windows

Slider windows are built with one or two moving window slashes that slide horizontally on a track. As slider windows open and close with a gentle effort, they are easily maintained. Slider windows will allow a large amount of natural light to enter your home, which is particularly beneficial during the dark winter months.


Picture Windows

A unique and equally attractive window option, picture windows will allow you to experience Newmarket’s lovely views with ease. As picture windows do not open, they are extremely secure and energy efficient. Picture windows also have no moving parts, so they become the easiest window to customize, making them an overall excellent window option for any home in Newmarket.

About Newmarket

Consistently named one of the best places to live in Canada by MoneySense Magazine, Newmarket is garnered as one of the most dynamic, diverse, and desirable towns to live and work in.

Newmarket is located in York Region approximately 50 km north of downtown Toronto. This central location between the bustling city and picturesque cottage country allows for a small town charm while providing big city amenities, such as premium healthcare facilities (Southlake Regional Health Centre), upscale shopping centres (Upper Canada Mall), and advanced transit networks (vivaNext rapid transit system).

Campbell Museum.
