Custom Built for You

No two homes are the same, nor should their windows and doors be. Every door we install is built at the factory to the customer’s own configuration, style, and finishing. Every single window we replace is custom-made to perform best in its specific position. Your windows and doors don’t get pulled from a shelf in a warehouse, but are manufactured specially for you, one after the other, together.

Certified Professional Installation

Without a professional installation, no window or door will perform as designed, no matter how good it is. Moreover, you risk damaging both your home and your windows or doors. Our installers are factory-trained to know the products inside out, and know how to install them. They are Window-Wise certified professionals who undergo training and are subject to random worksite inspections. But first of all, they take pride in what they do, and improve the customers’ homes like they do their own.

Customer satisfaction is our main performance benchmark, and we have built our business model to offer you an affordable, fast and trouble-free experience.

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!
