Oshawa is the eastern anchor of the Golden Horseshoe with a long history as an automotive centre, being the home of General Motors Canada. The population of the city is just over 150,000 and continues to grow each year as new residents discover its many amenities.

The city is known as a centre for post-secondary education and health care, and also popular because of its fairly close proximity to Toronto (45-minute drive). However, many homes in Oshawa are old builds in the southern half of town and could use a renovation. The northern half of Oshawa is suburban with homes typically from later decades. These homes, although new, can make the investment to upgrade their windows and doors to increase the value of your home.

Thanks to our high quality of service, Oshawa homeowners have long turned to us to help in their renovation projects.
