Northern Window & Door Manufacturing Ltd. is a family-owned and operated company for 26 years, with a complete team of manufacturing, sales and installation staff to assist you with your next renovation or construction project.

We manufacture a broad collection of sliding, casement, awning, bay and bow windows and doors. We specialize in custom vinyl windows serving residential clients looking to replace existing windows or who are building new.

Everything we manufacture in our Hardisty Street plant is made to each customer's specifications; we don't just manufacture stock sizes. We manufacture our windows complete from raw stock to finished product.

We offer free in home estimates for installations and will send a salesperson to your home to discuss your options. We offer a complete project from design to installation, all done by our highly trained staff.

A prime advantage to using a local manufacturer like Northern Windows is a quicker turn-around time and accessible, knowledgeable people who can answer all your questions.

Manufacturing our own products allows us to monitor and control all aspects of production to ensure a quality, worry free, low maintenance product for our customers. We manufacture windows for residential (renovation or new construction) applications using the highest quality components from industry leaders.

We assemble our doors with a custom frame and unique double weather stripping designed to provide stability and comfort in our northern climate. For selection we offer steel insulated doors with hundreds of glass design options to choose from.

As part of our commitment to the community and to the area we work in, Northern Windows donated land for the Ogden/Simpson St. Veggie Garden and we support countless other local organizations – making us a genuine representative of Thunder Bay's finest.
