Ontario writes its own building code, and the egress rules for a basement bedroom window in London come from the Ontario Building Code rather than the national one. The numbers are close to the national figures but they are not identical, and the OBC is what your inspector will hold you to.
What shapes a window well in London is southwestern Ontario clay with heavy lake-effect snow loading on covers. It is roughly 3,230 km by road from our plant to London, which is why freight runs $324.00 CAD and transit 2 to 15 business days.
The steel arrives at our Calgary shop as flat coil and leaves as a finished well. That is why London orders skip the distributor markup, and why an odd size is a quote rather than a refusal.
Ordering a window well in London
A London order ships for $324.00 CAD regardless of how many wells are on it, arriving in 2 to 15 business days. Stock galvanized sizes go out within one to two business days. Powder coated wells are finished to order, which adds one to two weeks before dispatch.
What the OBC asks for
The Ontario Building Code sets out the opening and clearance a basement bedroom window must provide. A 30 inch projection gives 762 mm in front of the window, which clears the 760 mm figure the national code uses, but confirm the current OBC requirement and any municipal amendment with your building department in London before you order.
Permits
Enlarging a basement opening to meet egress means cutting the foundation, which is structural work and generally needs a permit in London.
Measuring before you order
Three numbers, in this order. Width runs along the foundation wall and should clear the window opening on both sides. Projection is how far the well stands out from the wall. Height is from finished grade down to where the base will sit. If the hole is already dug, measure the hole rather than the window.
If you are replacing rather than installing new, measure the window and the excavation, not the existing steel. Decades in the ground change a well's dimensions.
Common questions from London
What does London require for a basement bedroom window?
The governing document is the Ontario Building Code, administered locally through your municipal building department. A 30 inch projection gives 762 mm of clearance in front of the window. The window itself has its own opening requirement, so confirm both before you order.
How much does shipping a window well to London cost?
Freight to Ontario is $324.00 CAD per order, not per item, and transit runs 2 to 15 business days on top of the build time. Because it is charged per order, several wells ship for the same price as one.
Can I get a size that is not listed?
Yes. We manufacture in our own shop, so any width, projection or height is possible. Send the three measurements and we will quote it for delivery to London.
Do you deliver to London?
Yes. We ship to every province and territory in Canada. Delivery is curbside on a liftgate truck and somebody needs to be there to receive it.
