Dufferin Windows Limited was started in 1972 by Jim and Jean Cheyne and Jean's father, Mac Cunningham, in Jean's hometown of Shelburne, Ontario.  Jim had spent nine years working for a window manufacturer and saw that his knowledge and woodworking skills could result in a profitable business for his family.  In 1982, Jim's daughter joined the company and, along with her husband, is moving to ensure the growth of Dufferin Windows Limited, while at the same time maintaining the "small-business" strategy that made her father's company so successful.

What started out as a 3500-square foot custom wood window show has grown into a 35,000-square foot manufacturing facility that produces many standard and custom window and door products.

In 1974, an addition of 4900 square feet was added to accommodate lumber storage and to spread out the assembly area.  By 1976, more manufacturing space was needed so the building was doubled to 16,800 square feet.  In 1987 we had once again out-grown the building due to a substantial increase in product llines.  An extension of 8400 square feet was added.  At this point, Jean suggested that if the building got any bigger, she was going to quit!  In the fall of 2001, after Jean retired, we were awarded a very large contract in Michigan, which would substantially increase our production.  The decision was made to add another 10,000 square feet for increased production area and storage.

Product lines include wood windows, vinyl clad windows, all vinyl windows, steel and fibreglass insulated entrance systems and patio doors.  All prodcuts are available in standard sizing for new construction, or custom sizing for replacement.  Because we are a family business, we have the ability to easily adapt to virtually any customer's request.  Products such as Simulated Divided Lites, return channels and various widths of vinyl Brickmould have been added to accommodate customers' requests.

Due to the knowledge and ingenuity of management, we have the ability to do our own bending of vinyl profiles, which enables us to do almost any shape imaginable in our wood, vinyl clad or all vinyl products.  Because of the high demand for replacement windows in century homes, we have developed a fully functional all vinyl camber top double hung window, allowing these customers to keep the look they want, but benefit from a maintenance-free window.

The dedication of our employees is one of our strongest assets.  Their input and skill level is highly regarded and invaluable.  Our "core" staff each have a minimum of 15 years' experience with the company, and each one is specialized in a different aspect of manufacturing.  All employees are dedicated to providing our customers with the highest quality we can build.

Customer satisfaction has always been a huge part of what we do.  We strive to keep our quality high and our service work to a minimum.  We only use quality materials in every product we manufacture, and it is obvious in the end products we provide to our customers.
