Nordik Windows & Doors, Trusted Since 1982

Nordik Windows and Doors has built a reputation as one of the most trusted window and door replacement companies in Ontario.

Nordik Windows began manufacturing windows for the new home construction market in 1982. In 1986, Nordik started selling in Ottawa the replacement windows it built under its own retail brand — Verdun Windows and Doors.

Since then, Verdun Windows and Doors has built a reputation as one of the most trusted window and door replacement companies in Ontario. With hundreds of customer reviews, our average customer rating on Homestars is 9.7 out of 10. We were also awarded the Homestars "Best of" designation six out of the last seven years.

We have re-branded our retail operations in the GTA under our original name, Nordik Windows and Doors, and we will continue to provide the same level of quality and service that has made us one of the largest and fastest growing replacement window and door businesses in Canada.

Winter Installation

Kevin and his crew had to brave -31 (with wind chill) temperatures to replace 19 windows in our house and managed to get them done in the promised 2 day timeframe. They were professional, efficient, did a fabulous job and we couldn’t be happier, thanks.
