Before & After Highlights
Torwin transformed an outdated double-door entryway into a stunning new configuration: a single door flanked by two large sidelites. The original setup felt dated and blocked natural light, limiting the home’s visual appeal and connection to the outdoors.
After a personalized consultation, Torwin handled the entire structural conversion with care—from framing and insulation to expert installation. The result is a bright, modern update that enhances the home’s aesthetics and performance. The homeowners were thrilled with the seamless before-and-after transformation and improved functionality.
These homeowners wanted their full-home remodel to reflect their personal style—starting with their windows and doors. They turned to Torwin for custom solutions off a recommendation from their designer. After showroom visits and consultations, we installed premium black vinyl windows, black doors, a bay window conversion, and an enlarged patio door.
The project required plumbing and electrical adjustments, precise brickwork, and creative installation behind Juliette balconies. The result? A bold, modern transformation that stands out beautifully in their neighbourhood.

Frequently Asked Questions About Torwin Windows and Doors
How much does window installation cost in Toronto?
Window installation costs in Toronto vary based on window type, size, frame material, and the number of windows installed. At Torwin, every custom window project starts with a free, no-obligation consultation so we can measure your space, discuss your goals, and provide a transparent, itemized quote. We offer financing options and work to deliver high-performance, energy-efficient windows that fit your budget without sacrificing quality.
What is the difference between fiberglass, vinyl, and aluminum doors and windows?
Each material offers different benefits. Fiberglass entry doors are highly durable, energy efficient, and resistant to warping, denting, and weather damage, which makes them an excellent choice for Canadian climates. Vinyl windows and vinyl patio doors are budget-friendly, low-maintenance, and offer strong thermal performance. Aluminum and aluminum clad windows provide a sleek, modern look with excellent strength, often paired with glass patio doors and contemporary designs. Our team can help you compare materials based on your home’s style, energy goals, and long-term value.
How long does exterior door installation take?
Most exterior door installation projects are completed in a single day. After your initial consultation and accurate measurements, our in-house residential door installers handle the full job, including frame fitting, insulation, weatherproofing, and finishing.
