Our Egress Window Installation Process
-
Site Assessment
We visit your home to measure the proposed opening, evaluate the foundation type (poured concrete or block), determine window well depth, and confirm building code requirements for your municipality.
-
Concrete & Foundation Cutting
Using professional core-cutting and saw equipment, we precisely cut the new opening in your foundation wall — minimising dust and disruption inside your home.
-
Window Framing
We install the structural lintel and frame the rough opening to the manufacturer’s specifications, ensuring a proper load path and a weathertight fit.
-
Window Installation
The egress window (casement, hopper, or sliding) is set, levelled, sealed, and secured — installed to Ontario Building Code and Energy Star® standards.
-
Window Well Installation
We excavate, position, and secure a steel or poly window well, backfill with drainage gravel, and ensure proper waterproofing against the foundation wall.
-
Cleanup & Inspection
The site is cleaned inside and out, the installation is checked for air, water, and structural integrity, and we walk you through operation and care.

The window must be openable from the inside without a key or tool, and the sill height must be no more than 1,500 mm (59 in) from the floor.
