Window & Door Replacement in Toronto & the GTA

Costs for window replacement in Toronto vary depending on the number of windows, sizes, installation method (retrofit vs brick-to-brick), glass options and any additional work such as new interior trim or exterior capping. Most homeowners receive several quote options from UGS — for example, a standard energy-efficient vinyl window package and an upgraded triple-pane Low-E option. The best way to get accurate pricing is to schedule a free in-home consultation so we can measure each opening and provide a detailed written estimate.

With retrofit window installation, your existing frames and interior trim stay in place, and we install new vinyl window units into the current openings. This is often more budget-friendly and less invasive when frames are still in good condition. Brick-to-brick window replacement means we remove the entire old window down to the structural opening and install a new frame, insulation and exterior capping. Brick-to-brick provides maximum insulation and a completely fresh look, which is ideal when the old frames are rotted, poorly insulated or outdated.

For a typical Toronto home, most full-house window replacement projects are completed in one day by our WSIB-insured installation crew. Larger homes or projects that include entry doors, patio doors and complex bay or bow windows may require two days. Before we start, we will give you a clear schedule so you know exactly when our installers will arrive, how long the work will take and when your home will be fully cleaned and ready to enjoy.

Yes. UGS offers financing options to help spread the cost of window and door replacement over time. Depending on your approval, you may qualify for low-monthly-payment plans or 0% interest financing for a promotional period. During your consultation, we can review available financing programs, estimate monthly payments for your specific project and help you choose the option that fits your budget.

Many Ontario homeowners can access rebates or incentive programs when they upgrade to qualifying energy-efficient windows and doors. These programs may require specific Energy Star ratings, installation by a professional contractor and sometimes a pre- and post-upgrade energy assessment. Because rebate programs change, we always check current Ontario window and door rebate options for you and explain what is available before you decide on products and installation.
