Egress Window Well Covers — Atrium & Sloped Styles — Toronto & GTA
Custom-made egress window well covers for basement and casement windows across Toronto and the GTA. We build Atrium (Dome) and sloped cover designs around the window opening, well dimensions and clearance needed for safe, practical access.
Egress Window Well Covers Designed Around Your Window Opening
A standard flat or low-profile cover may interfere with a casement window that swings outward into the well. An Atrium (Dome) style cover rises above the opening to create usable space for the window sash.
Each cover is measured and manufactured for the specific home. The dimensions account for the window's swing, the shape and projection of the well, and the access needed to open the cover from inside. Compare all custom cover options or review basement window well covers when the window does not need an Atrium design.
Inside access matters
We plan the cover and its opening method around the window and well, then check that the window and cover open as intended.
What Makes an Atrium Cover Different?
Full Window Clearance
The raised profile is designed to let an outward-opening casement or egress window swing fully open.
Opens From Inside
The hinged Atrium cover can be pushed up from inside the open basement window without a separate escape hatch.
Custom Manufactured
Width, projection, height and window swing are measured for a secure fit around the actual well.
Clear Polycarbonate
A durable clear cover allows natural light into the basement while helping reduce direct exposure to weather and debris.
Atrium vs. Sloped Egress Window Well Covers
Both styles are custom-built around the window opening and well dimensions, but they solve different clearance needs. The right design depends on how far the window swings, how much height is available and how the cover needs to open from inside.
Custom Fit for the Opening
We assess the window swing, well projection, height and access path before recommending a profile. There is no one-size-fits-all egress cover.
Manual Inside Opening
Atrium covers do not open automatically. The window is opened first, then the hinged cover is manually pushed upward from inside.
Weather Protection
Both styles use clear polycarbonate to help reduce direct exposure to rain, snow and debris while allowing natural light into the well.
Toronto & GTA Service
We provide custom egress window well cover solutions across Toronto, the GTA and selected Southern Ontario communities.
Atrium Covers Are Manually Pushed Open From Inside
The hinged Atrium cover does not open automatically. From inside the basement, the homeowner opens the window first, then manually pushes the cover upward to create the exit path. There is no separate escape hatch or powered mechanism.
- The casement window has room to swing outward.
- The cover can be opened from inside the well.
- The design avoids permanent obstructions in the exit path.
- The cover remains protective during normal day-to-day use.
Important Egress Consideration
The cover is designed around clearance, access and the usable window opening. Building-code requirements depend on the complete window, well and installation, as well as the local jurisdiction. Final compliance should be confirmed for the specific property.
Manual opening — not automaticFrom inside the basement, open the casement window first, then manually push the hinged Atrium cover upward. The cover does not lift on its own.
From Measurement to Installation
Assess the Opening
We review the window style, well dimensions, projection and available height.
Confirm the Swing
The window is measured in its open position so the dome provides sufficient clearance.
Build the Cover
The cover is custom manufactured for the shape and operating requirements of the well.
Fit and Test
The installed cover and window are tested to confirm that both open as intended.

Atrium and Egress Cover FAQs
What is an Atrium (Dome) window well cover?
It is a raised custom cover that creates additional space above the well. This shape is particularly useful when a casement or egress window needs to swing outward.
Does the cover need a separate escape hatch?
No. Our Atrium design allows the cover itself to open. The hinged cover is pushed upward from inside through the open window.
Will the basement window fully open?
The cover is measured around the open window position so the Atrium height can provide the required swing clearance.
Are Atrium covers made in standard sizes?
These covers are custom measured because window height, swing, well shape and projection vary from one home to another.
Does an Atrium cover meet egress requirements?
The cover is designed to preserve clearance and inside access. Compliance depends on the complete window and well installation and the rules in the local jurisdiction, so each project should be assessed individually.
What information should I send for an estimate?
Send photographs of the window and well, your location, approximate width, projection and height, and a photo showing the window fully open.
