How Much Does It Cost to Add a New Window Opening in Winnipeg?
Adding a brand-new window to an existing wall in Winnipeg typically costs between $1,800 and $5,500, and sometimes more.
Unlike swapping a window into an existing opening, this project means cutting through your drywall, insulation, exterior siding, and structural framing. That extra labour and demolition is exactly why a new opening costs significantly more than a standard swap.
Here is what drives your project price up or down:
| Cost Factor | Impact on Final Price |
| Wall Type | Framing a simple non-load-bearing wall is the cheapest option. Cutting through load-bearing walls, brick veneer, or concrete pushes the price to the higher end. |
| Window Size | Small basement or bathroom windows cost less. Large picture and bow windows require heavy structural support and drive the price up. |
| Exterior & Interior Finishing | Matching existing stucco, brick, or siding on the outside, and repairing drywall and paint on the inside, adds both material and labour costs. |
| Structural Engineering | If the wall is load-bearing, you may need a structural engineer to sign off on a heavy-duty header. Budget $500 to $1,500 and extra time. |
Note: If you are simply swapping an old window into an existing opening, the cost drops sharply. See what a standard window replacement costs in Winnipeg for those numbers.
Rebates Do Not Apply to New Openings
The Efficiency Manitoba rebate of $100 per window covers replacements only. Windows installed in new openings are not eligible.
That widens the real gap between the two projects. A ten-window replacement can pull $1,000 back in rebates. A new opening pulls nothing.
Framing, Structure, and Permits
The structural work is the biggest variable in this job. Cutting into a standard partition wall is fast and straightforward. If the wall holds up your roof or second floor, the crew has to build temporary supports, cut the opening, and install a heavy-duty header to carry the weight safely. Older Winnipeg homes with masonry veneer or plaster walls take more time and specialized tools to cut cleanly.
Because you are altering the structure of your home, the City of Winnipeg generally requires a building permit. Skipping this step can void your home insurance or cause major problems when you sell.
Our installation crews handle the framing, sealing, and exterior finishing as one job, so the opening is weathertight before the drywall goes back up.
Why This Isn’t a DIY Project
Cutting a hole in your house touches structural framing, insulation, electrical wiring, and exterior weatherproofing all at once. Get any of those wrong — an undersized header, a punctured wire, a poorly sealed sill — and you are looking at a sagging roof, serious winter drafts, or water rotting out your walls.
This is one project where hiring an experienced crew is non-negotiable.
Payment Options
New openings can be spread over time with financing from $49 a month, including no payments for up to 12 months and 0% on approved credit.
