Top 5 Windows and Doors Companies in Toronto
Toronto’s climate ranges from freezing winters to hot, humid summers, which makes choosing the right windows and doors crucial for homeowners. Quality, energy-efficient windows can significantly reduce heat loss in winter and keep your home cooler in summer – in fact, upgrading to ENERGY STAR windows can cut energy bills by around 7–12% on . Beyond comfort and savings, well-built windows and doors also boost home value and curb appeal, an important factor in Toronto’s competitive housing market. With many older homes and new builds across the GTA (Greater Toronto Area), selecting a reputable company ensures your installation is done right.
Below we list five of the best window companies in Toronto (who also handle door installation) known for energy-efficient products, professional service, and modern designs.

Clera Windows & Doors is a family-run Ontario manufacturer that has been in business since 1978.

The company’s confidence in its quality shows in its warranty: a non-prorated, transferable lifetime warranty that covers all window components (frame, hardware, even glass). Clera typically works on residential window and door replacements, from classic Toronto brick homes to suburban houses, and is often praised for its personalized customer service. Their factory-direct model (no middlemen) means homeowners get quality windows and doors at fair prices. If you’re seeking a trusted local window company with a long track record, Clera Windows & Doors is a solid choice for your project.
Renewal by Andersen is the luxury, full-service window replacement division of Andersen – a brand with over a century in the window industry. In the Toronto area, Renewal by Andersen offers custom-built windows and patio doors featuring their exclusive Fibrex® composite frames. This innovative Fibrex material combines the strength and stability of wood with the low-maintenance benefits of vinyl, resulting in frames that won’t rot, peel, or require frequent repainting. Homeowners who choose Renewal by Andersen get a start-to-finish experience: a detailed consultation, professional measurement and installation, and robust warranties (often 20 years on glass, 10 years on components and labor). Their windows are highly energy-efficient with high-performance glass options, making them well-suited for Toronto’s mix of cold winters and hot summers. Renewal by Andersen is often the go-to for homeowners who want premium quality and a “white-glove” installation service – for example, those upgrading a longtime family home or seeking a specific custom window style that fits a historic property. While this option can be one of the pricier choices for window and door installation in Toronto, the combination of Andersen’s reputation, material technology, and craftsmanship secures Renewal by Andersen a spot among the top window companies in the GTA.
