Our windows are built stronger

The structural construction of our windows is second to none. We use the highest quality materials and build our windows on a single, one-piece solid frame. Need a multi-paneled window with a large fixed light, flanked by two casements above awnings, with brickmould all around? One frame. All of our windows are locally built in Ontario to your exact specifications.

A modern living room with high-end furniture and plants.

Our windows are brighter

Our one-piece structural contruction with stronger but leaner window frames, sashes, and integrated mullions, allows for less plastic and more light in your window. Compare the 4-½" distance between two glass panels on our RevoCell® windows to the 6" - 7½" on competitors’ windows. Getting more natural light in your home is the very reason you have a window in a wall, isn’t it?

We Appreciate Your Patronage!

I just had the windows replaced in my house, Sean and Rick were very kind and treated my home like it was their own. From start to finish their team stayed on top of the mess which made for an effortless quick tidy up once they left. The quality of the install is on point 100%. Couldn’t ask for a better job.

Martin & Anita in Barrie

Highly recommend Northern Comfort Windows, have used them twice for whole house window replacement. Both times salesperson & installers were excellent. However, this time the installer crew of Mitch, Allen & Paul were beyond our expectations, the detail of the trim work on our exterior walls with field stone was absolutely amazing.

Private user in Haliburton

... Peter gave us great recommendations for our doors first order, and our windows the next. we just put in an order for the back of our house and he was able to get us our dream windows! We cant thank Peter, Northern Comfort or the install team enough. The quality of service, product and install is why we are back for a third time!
