Oshawa's homes range from the Edwardian and Arts and Crafts character homes in O'Neill and McLaughlin to post-war bungalows in Lakeview and Vanier, and the newer detached homes and townhouses going up in Taunton and Kedron. A large portion of Oshawa homes have windows and doors that are well past their prime, letting in cold air from Lake Ontario and driving energy costs higher every winter.
Clera builds every window and door at our Ontario manufacturing facility and installs them using our trained and licensed crew. That means no third-party suppliers, no outsourced labour, and factory-direct pricing that reflects the true cost of a quality product. Every installation is covered by a non-prorated, fully transferable lifetime warranty, with flexible payment options available to help Oshawa homeowners complete their home improvement project on their own timeline.
Whether you’re looking to replace windows in a post-war bungalow or considering a larger-scale home renovation project, Clera offers a full range of ENERGY STAR-certified windows, entry doors, and patio doors, built for Ontario's climate and customized to your home.
