    Unlike many of our competitors, we have an in-house carpentry and design team. We opt not to hire temporary contractors – we prefer to work with those we know to be proven performers. 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%. If you’re checking out Oakville windows and doors reviews, Torwin’s services are consistently highly ranked.


    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 for 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 Oakville & the surrounding areas for nearly 35 years with custom, high-quality and efficient windows and doors.
