Window Installation Service
Not every window job is the same. But every window installation in Toronto calls for the same precision, regardless of the scope. Replacing a cracked basement window, upgrading aging single-pane units throughout a house, or fitting windows into a newly framed opening each requires a different approach — and the margin for error is small in all three cases. In Toronto, Ontario, the climate adds another layer: poorly sealed frames let in cold air in winter, humidity in summer, and water whenever it rains hard. FC Locksmith is a licensed company in Ontario. Our team handles window installation and replacement for residential and commercial properties, with a focus on getting the fit and seal right the first time.
Window Installation in Toronto — What the Job Actually Involves
Window installation in Toronto isn’t just about setting glass into a frame. The opening needs precise measurements, the old frame has to come out cleanly, and the new unit must sit level and square before the seal is applied. A window that’s even slightly off will develop gaps, fog between panes, or fail to lock correctly — and in this climate, those problems get worse with every season. Our team carries the tools and hardware to handle the complete process, from removing the old window to finishing the interior and exterior trim.
Most installations are completed in a single visit.

Types of Window Installation Jobs We Handle

Reach out at 416-619-4912 and a technician will walk you through what’s involved.
How the Installation Process Works
When the call comes in, the dispatcher takes down the details — window type, floor level, number of units, any access considerations — and sends a technician to assess and measure. On installation day, the team arrives with the necessary equipment and gets to work without a long setup delay. Old windows come out carefully, the rough opening is checked and adjusted if needed, and the new unit is set, levelled, and sealed. Interior and exterior finishing is done before the team leaves.
Single-window jobs are typically done the same day. Larger projects are phased so the property is never left exposed between sessions.

Residential and Commercial Window Installation Across the GTA
Toronto’s climate makes window quality matter more than in milder cities. Winters push cold air through any gap, and summer humidity causes wooden frames to swell and bind. Getting the right window for the application — and installing it precisely — reduces energy loss, noise, and long-term maintenance across the property.
Our company handles residential work for homeowners and landlords across Toronto and the surrounding GTA, as well as commercial projects for retail units, office buildings, and mixed-use properties. Every job follows the same standard: measure accurately, install carefully, and finish cleanly.

Frequently Asked Questions About Window Installation
How Long Does a Typical Window Installation Take?
Most single-window installations take between one and three hours from start to finish, depending on the window type, floor level, and condition of the existing rough opening. Replacement jobs in standard openings tend to be faster than installs into new or modified openings. The technician provides a time estimate before work begins. If the rough opening needs framing adjustments or if hidden damage is found during removal of the old unit, the team explains what’s involved and confirms the revised timeline before continuing.
What Window Types Can You Install?
Our team is available for the installation of single and double-hung, casement, awning, sliding, picture, and basement windows for residential properties, along with storefront and commercial glass for business locations. If you already have a specific window selected, bring the specs and the technician can confirm it fits the opening before the job is booked. If you’re starting from scratch on selection, a site assessment narrows down the options based on the opening dimensions, ventilation requirements, and any applicable building code considerations for that specific location and floor level.
Do You Handle Window Replacement as Well as New Installations?
Yes — window replacement is part of the service. Whether you’re replacing a cracked unit, upgrading from single-pane to double-pane glass, or swapping out windows that no longer seal, our team handles removal of the old window and full installation of the replacement. The process mirrors a new install: measure, remove, prepare the opening, set the new window, and seal and finish. Disposal of the old window is included in the job, and the estimate covers everything upfront so there are no add-ons on the day of the work.
Can You Work on Older Toronto Homes With Non-Standard Openings?
Older Toronto homes often have rough openings that don’t match current manufactured window dimensions, along with deteriorated framing or original plaster that complicates removal. Our team has experience with older construction and factors this into the site assessment. In some cases, a custom-sized window or additional framing work is needed before the new unit can go in — the technician identifies this during the initial visit and explains the full scope before any work begins. Getting the opening right is what determines whether the installation holds up long-term.
