Frost reaches 1.8 m in Grande Prairie, which is deeper than most of the country and deep enough that it governs the whole installation. A well that stops short of the frost line will be lifted by the ground underneath it sooner or later.
What shapes a window well in Grande Prairie is Peace Country clay that holds water and a frost line deeper than most of the province. It is roughly 456 km by road from our plant to Grande Prairie, and delivery there takes 2 to 15 business days.
The steel arrives at our Calgary shop as flat coil and leaves as a finished well. That is why Grande Prairie orders skip the distributor markup, and why an odd size is a quote rather than a refusal.
Getting one to Grande Prairie
Shipping to Grande Prairie runs $189.99 CAD per order. That is per order, not per well, so a whole house of wells costs the same to ship as one. Allow 2 to 15 business days in transit on top of one to two business days for galvanized stock, or one to two weeks if you want gloss black.
Working with a 1.8 m frost line
The practical consequence is depth. Excavations here go deep, which usually means a taller well than the same window would take further south, and often two wells stacked where the drop exceeds the tallest single height we roll.
Stacking for depth
Where the drop is deeper than 42 inches, two wells of matching width and projection fasten together. Order both and say so in the order notes so we can match the flanges.
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 Grande Prairie
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 Grande Prairie.
How deep should a window well be in Grande Prairie?
Deep enough that the base sits below the level the excavation reaches, with the lip finishing at grade. At around 1.8 m, frost design depth here is well above the national norm, so excavations tend to be deeper and the well taller than the same window would need further south. Measure from finished grade down to where the base will actually sit, not from the window.
How much does shipping a window well to Grande Prairie cost?
Freight anywhere in Canada is $189.99 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.
What does Grande Prairie require for a basement bedroom window?
The governing document is the Alberta Building Code (NBC 2020 AE), 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.
Treat this as orientation rather than a code interpretation. Alberta Municipal Affairs and your local building department in Grande Prairie set what actually applies to your build.
