Window wells
Protect Your Ground-Level Windows
Prevent basement water infiltration with window wells installed to code, fully drained into your French drain system.
What is a window well
A retaining wall for your low-set windows
A window well is a galvanized steel or polymer structure anchored to your foundation, around a window located at or below ground level. It acts as a retaining wall between the surrounding soil and the window while channeling water into your French drain.
A poorly installed window well — or the absence of one — is one of the most common causes of basement water infiltration in the Greater Montreal area.
Why Install a Window Well
Four key reasons why a properly designed window well is essential for any foundation with ground-level windows.
Prevents water pooling
Without a window well, rainwater and snowmelt collect against the window and eventually leak into the basement.
Keeps out soil, leaves and debris
The window well acts as a retaining wall that prevents soil, leaves and snow from blocking the window.
Required by code
If your window is at or below grade, a window well is required by the building code.
Safe emergency egress
A properly designed window well provides a quick exit from the basement in case of emergency.

Components
The 4 elements of a complete system
An effective window well isn't just a wall — it's a system integrated with your foundation drainage.
Window well & cover
Galvanized steel or polymer well anchored to the foundation, with a cover that keeps debris and animals out.
3/4" net gravel
Washed crushed stone that fills the bottom of the well to allow water to drain quickly through the system.
Inspection port (cleanout)
Inspection conduit that lets us camera-scope the French drain and detect any blockages.
French drain connection
Water collected in the well is directed into the foundation French drain, then sent to the sump pit or storm sewer.
