    Older windows and doors can leave a lot to be desired when it comes to good energy efficiency. Torwin’s custom, high-quality, and energy-efficient replacement windows and doors in Toronto, help reduce peak heating and cooling loads while keeping out those uncomfortable drafts. The fact is, Torwin’s replacement windows and doors use the latest technology to make your home more comfortable, no matter the season. And with an installation team that is professional and knowledgeable, we make sure it is smooth sailing for homeowners – we know a renovation job can be stressful!

    Our showroom is conveniently located just minutes north of Toronto, close to the 404. Visit us in person and experience the difference! We have a large selection of both windows and doors that are made-to-order and custom options to match your unique taste, budget, and specifications. Our showroom allows you to take a closer look at your options before committing. Reach out and speak to a real person before making any big decisions. Our reps would love to help guide you in choosing the right windows and doors for your home. 


    We value both energy efficiency and style! Our Energy-Star certified windows are perfect for Toronto’s humid summers and subzero winters, insulating your home to keep the elements out. But our selection is also carefully chosen to match the latest window trends and design. That’s why, as industry leaders in Toronto, we have a wide variety of choices and finishing for awning windows, bay windows, bow windows, and greenhouse windows–including a variety of custom aluminum capping options. In addition, we offer a range of customization options, from seats for a brand-new bay window to custom trims or knockouts to expand your window size. 

    Our window replacement experts in Toronto will assist you in choosing the right product for your home while providing helpful suggestions to optimize its look, feel and performance. If windows were an afterthought for you in the past, be prepared to love them once they’re replaced!


    If you’ve never thought much about your front door, allow us to help change your mind! A grand entryway gives off a solid first impression of your home. An updated door can provide an instant facelift for the rest of your home, with a fresh new look that also increases curb appeal. Unfortunately, older doors are also prone to damage, decreasing overall energy efficiency. A new door from Torwin will combine the latest in energy-efficient technology and materials with high-quality construction and installation to keep the outside air out and the inside air in. And a typical door installation project in Toronto can take as little as one day, making it an easy, low-maintenance home improvement job you can take on with relatively limited disruption.

    Whether you’re looking to update the exterior door trim with headers and crowns, expand your current entryway for an oversized door or are just looking for a simple door installation in Toronto, our in-house, full-time carpenter team can handle any kind of custom work. Choose from a selection of trims, windows, cutouts and colours, and feel free to inquire about specific features you may have in mind. We have the skill and expertise to make your home match your vision!


    When it comes to keeping your home efficient, comfortable, and looking its best, there’s nothing like new custom, energy-efficient replacement windows and doors from Torwin. Energy Star certified products save you both energy and money.

    The Torwin Touch

    We pride ourselves on our expert project management and customer service, honed from our decades of experience in window and door installation in Toronto. From our first point of contact, you’ll feel confident that you and your home are in good hands. We walk you through all your options for replacement windows and doors in Toronto, helping you stay on budget while fulfilling the vision you have for your project. 

    Our priority is to deliver the best work while keeping you informed and in the loop with the progress made. To do this, we assign a project manager for each job to oversee all the details, whether big or small and ensure that everything is going smoothly.  

    Our Craftsmen in Windows & Doors Replacement

    Unlike many of our competitors, we have an in-house carpentry and design team. Hiring temporary contractors as jobs become available is a risky endeavour. Without a long-standing previous relationship, we can’t be assured of work quality, nor the experience or dependability of the workers. At Torwin, our staff have been with us for years, and we know them personally to be reliable, experienced and professional. This gives us the confidence to stand behind their work 100%.

    Our Selection

    Rather than holding an existing stock of windows and doors for you to choose from, we receive our inventory made to order, which means our products will always be top of the line when it comes to style, design and energy efficiency. Made to order also means you can customize certain features of your windows and doors, creating an item that perfectly fits your needs and homes. We also offer entirely custom designs made based on your requests and specifications. Contact us to learn more about our design process.

    Torwin has been servicing Toronto & the surrounding areas for nearly 35 years, with custom, high-quality and efficient windows and doors. We provide excellent financing options to help you get the look you want while staying within your budget. Whether you’re looking to sell or just hope to get more gratification out of your house, boost your home’s curb appeal with the Torwin Windows & Doors Team today!
