Three common starting points
EliteCraft reviews the whole project—not just the window size.
Foundation type, exterior access, drainage, the intended room use, window operation and permit requirements can all affect the final scope.
Enlarge an existing opening
The existing foundation opening is cut larger so the selected window can provide the required clear opening.
Create a new opening
A new location is reviewed for structure, exterior access, window-well placement, drainage and permit requirements.
Ontario egress basics
The actual openable space is what matters.
Frame size alone does not prove compliance. The clear opening is measured with the window fully open and unobstructed.
Minimum clear opening area
Approximately 3.77 square feet of unobstructed opening.
Minimum dimension
No clear-opening width or height can be smaller than approximately 15 inches.
Window-well clearance
Where the window opens into a well, clear space is needed in front of the opening.
Operates from inside
The escape opening must operate from inside without tools and remain open without extra support.
Permit note: The City of London lists new windows and enlarged existing windows as permit-required work. Final requirements are confirmed for the specific property and project.
Standard window program
We narrow down the likely fit for you.
EliteCraft's current stock program includes several low-profile, square and wide frame sizes. Customers do not need to choose the final size before requesting a quote.
34 × 3436 × 2445 × 21
Additional listed frame sizes include 30 × 28, 32 × 26, 34 × 25 and 38 × 23. Final egress compliance depends on the exact model's clear opening, operation and installed conditions—not frame size alone.

Egress window questions
What homeowners usually need clarified.
Does every basement bedroom need its own egress window?
Ontario requirements generally focus on a compliant outside opening on each floor level containing a bedroom unless a door on that level provides direct access outside. The exact layout still needs project-specific review.
Can an existing small basement window be converted?
Sometimes. EliteCraft reviews the existing opening, foundation, available height and width, window operation, exterior access and well requirements before recommending a solution.
Do I need a permit in London?
The City of London lists new windows and enlarging existing windows as projects requiring a building permit. Other work involving the foundation can also require review.
Can I choose a window from the stock-size list myself?
You can use the sizes as a planning reference, but the final model should be selected after confirming clear opening, rough opening, operation, structure and site conditions.
