If you’re in the market for a windows and doors replacement job in Toronto and the GTA, the experts at Torwin are here to help!

We’re a local business – a windows company near you! Our reputation is well earned, with nearly 35 years of serving the entire Greater Toronto Area and over 70 years of combined experience. We’re driven to maintain our credibility by bringing you the best customer service possible.

Dive in and see what makes Torwin different!


Our installers work for Torwin full-time. We don’t use subcontractors, unlike many of our competitors. While it can be more flexible for a company to hire workers as needed, it usually doesn’t guarantee the best quality work.

Temporary hires may not have the experience required to do a good job. And they may rush the installation process if they have other projects in the pipeline.

Our craftspeople don’t have to juggle competing priorities and are accountable solely to us. We schedule our projects to ensure they’re completed promptly to meet and exceed our clients’ expectations.

We even assign a project manager to each job, whether it’s an entire home or just a room, to keep everything running smoothly. And when an unexpected event happens, we’re prepared. By building some extra time as needed for our projects, we can address any challenges without causing delays downstream.


With experienced Torwin Windows & Doors employees on your job, you know your doors and windows will be installed perfectly. All our workers have the appropriate insurance, certificates, and training.

We often have clients asking if we’re Window Wise certified. This Canadian certification is designed to ensure a quality window installation.

While the answer is yes, our standards are actually higher. Window Wise installers are required to have at least five years of experience on the job. At Torwin, our crew chiefs have ten years or more, and they’re the ones calling the shots. When we say they’ve seen it all, it’s not an exaggeration.

With this extensive background comes confidence – we provide accurate time and budget estimates for all our jobs and will keep you informed of our progress and developments. You can trust our door and window installation service.


We’ve intentionally chosen to hire full-time installation teams to handle our door and window installation service. We also have installers who specialize in carpentry and masonry work to ensure our clients get the best possible service from our company.

Once we initiate the project, we send the same team to assess your home, take the measurements and complete the installation. This way, the staff assigned to you will be familiar with your home and can formulate an effective plan to tackle the work. There’s no risk of missing details or games of “broken telephone” when the same people are on the job from start to finish.

You can be confident that the staff on your team has installed all types of windows and doors. They can offer creative solutions and troubleshooting for those tricky projects. If your installation is simple, you can be sure it’ll be done quickly and efficiently. If your requirements are complex, rest assured that our staff has done something similar before – it won’t be their first time!


Did you know that all our products are custom-made and of premium quality? That’s right! Everything from the front door and window replacements to interior finishes is made to fit your home’s unique style.

We even take our materials above and beyond what’s standard for our industry. For example, many other companies offer medium-density fibreboard (or MDF) for the sills and trim of their window installations. Instead, Torwin offers real, primed and painted poplar wood products.

What’s more, Torwin offers a premium trim package, including bullnose sills, mullions, and backbands. So, if you want the best for your home in terms of style and quality, look no further.

And if you’re searching for something that will set you apart, we offer design services that can help you synthesize a look that’s one of a kind! So tell us your vision, and we can work together to achieve it, whether through customizing an existing model or creating one from scratch.


Of course, the windows and doors you choose are the most critical component of your home improvement project. All our replacement windows and doors boast the newest energy-efficient technologies and feature the latest Energy Star certification.

If you’ve heard that the Canada Greener Homes Grant can help offset the costs of replacement windows and doors, but you’re finding the program difficult to navigate, let us help! Now called the Home Efficiency Rebate Plus, if you’re a resident of Ontario, it’s administered through Enbridge Gas, with significant incentives for replacing your windows and doors.

Through our partnership with an energy audit service, we make the application and approval process turnkey for homeowners. We’ll help schedule the audit on a day and time that works for you, walking you through the paperwork and submission.

Once approved, you can choose from our full range of qualifying windows and doors, knowing you’ll receive a rebate and enjoy reduced energy bills for the long term.

The Torwin Difference means you don’t have to worry about the product or the installation! Our team of experts, including our in-house installers, get it right the first time, saving you time, money, and stress. The Torwin team can simplify any installation project with our expertise, attention to detail, and ability to work on time and within budget.

What’s more, with our wide selection of replacement windows and doors, you’re sure to find an option that will help with your energy costs, match your style, and bring some curb appeal to your home with a fresh new look!
