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, because it determines whether a straightforward insert replacement works or whether the job needs a full brick-to-brick approach.
What is brick-to-brick window installation?
Brick-to-brick means removing the existing window frame down to the rough masonry opening, rather than inserting a new frame inside the old one. It’s the correct method when a home has solid brick or stone construction rather than a modern wood-frame wall assembly. The approach preserves the original opening dimensions and produces a cleaner seal directly against the brick, but it requires more masonry work — cutting, mortar matching, and finishing — than a standard insert replacement.
How do I know if my Oakville home needs brick-to-brick instead of an insert?
The construction type of the wall is the deciding factor, not the age of the home alone. Solid masonry construction — common in Oakville’s older village core and some lakeside properties — generally requires brick-to-brick for a proper result. Homes with brick veneer over a wood-frame wall, which describes most newer Oakville construction, can typically use a standard insert replacement without the additional masonry scope. An on-site assessment is the only reliable way to confirm which category a specific home falls into.
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.
