Oakville’s housing stock varies significantly by area — older brick and stone construction concentrated in the village core and lakeside neighbourhoods, newer wood-frame construction with brick veneer further north and inland. That distinction matters more than most homeowners realize when it comes to window replacement, but the existing frame's condition, rather than wall type alone, determines whether an insert is suitable or full removal is needed.
What is brick-to-brick window installation?
Brick-to-brick removes the existing window, frame, jambs and casing to the stud opening. After vacuum cleaning and Blueskin membrane, the window supplied with brickmould and jamb extension is shimmed and secured to studs. Low-expansion foam, red tape over foam, new interior casing and exterior capping complete the work. This involves more removal and finishing than a standard insert replacement.
How do I know if my Oakville home needs brick-to-brick instead of an insert?
Retrofit inserts a new window into an existing frame only when it is sound, square and dry, preserving the existing interior finish. Age or brick veneer alone does not qualify an opening. Stud-to-Stud involves full removal to studs for compromised openings, structural repairs or rebuilding, or resizing. An on-site inspection confirms the appropriate method.
What happens to the lintel during a brick-to-brick replacement?
The lintel — the structural support spanning the top of the window opening — needs to be assessed before any cutting begins. In most cases the original lintel, whether steel or concrete, remains in place and continues supporting the masonry above. If the lintel shows deterioration or the opening is being resized, additional support or a lintel replacement may be required. This is not something to determine on-site during the cut itself; it needs to be part of the initial assessment.
Will the brick repair be visible after the work is done?
It shouldn’t be, if the mortar matching is done properly. Matching mortar colour and joint style to the surrounding brickwork is a significant part of what separates a clean brick-to-brick job from one where the repair is obviously visible from the street. This matters especially on street-facing walls where the finished appearance is immediately noticeable. See our masonry work for how that finishing is handled.
Do I need a permit for brick-to-brick window replacement in Oakville?
This depends on the scope of the work — specifically whether the opening size is changing and whether structural elements like the lintel are being modified. A straightforward brick-to-brick replacement at the same opening size with no structural changes often doesn’t require a permit, while resizing an opening typically does. Confirming this with the Town of Oakville before work begins is part of a proper project assessment.
Why does it matter whether the masonry work is done in-house or subcontracted?
When window installation and masonry repair are handled by two separate crews, the two parts of the job run on separate schedules, and responsibility for the final result can become unclear if something doesn’t align properly — the window installer can point to the mason and vice versa. Handling both scopes in-house keeps the project on one schedule with one point of accountability for the complete result.
