Professional basement egress windows services for Weston homeowners. Licensed, insured contractors serving the West Toronto area.
What Is Basement Egress Windows?
Basement egress windows are code-compliant windows sized for emergency escape and rescue from below-grade rooms. Ontario Building Code requires egress windows in every basement bedroom with a minimum unobstructed opening of 3.8 square feet, no dimension less than 15 inches, and a sill height no more than 3.3 feet above the floor. Installation involves enlarging the foundation wall opening, installing the window, and constructing an exterior window well with drainage. In Toronto and the GTA, egress window installation costs $3,500 to $7,000 per window.
Basement Egress Windows for Weston Homes
Looking for expert basement egress windows in Weston? Renovation Basements has been helping homeowners throughout the West Toronto area maximize their basement potential. The detached, semi-detached common in Weston present unique opportunities for basement transformation.
Egress windows are a legal requirement for any basement bedroom in Ontario and a smart upgrade for any below-grade living space. These code-compliant windows are large enough to serve as emergency exits, allowing occupants to escape and firefighters to enter in case of fire or other emergency. Beyond safety compliance, egress windows transform the quality of basement living by introducing dramatically more natural light and fresh air ventilation than standard basement windows. Many Toronto and GTA homes were built with small, high-set basement windows that provide minimal light and cannot serve as emergency exits. Replacing these undersized windows with properly sized egress units involves cutting through the concrete foundation wall, enlarging the opening, installing a code-compliant window, and constructing an exterior window well with drainage. At Renovation Basements, our egress window installations are engineered for each property's specific foundation type, wall thickness, and soil conditions. We handle every aspect from permit acquisition through exterior restoration, ensuring your new windows meet code requirements while enhancing the brightness and livability of your basement.
About Weston
Weston is one of Toronto oldest communities with rich industrial history along the Humber River. The river creates significant basement flooding challenges during heavy rainfall and spring snowmelt. Hurricane Hazel devastating 1954 floods through this corridor highlight the importance of proper waterproofing. Glacial clay soils hold water tenaciously. The revitalization with the Weston UP Express station has increased renovation demand.

Assessment & Window Specification
We evaluate your existing basement windows, measure the foundation wall thickness, assess soil conditions outside, and determine the optimal size and position for the egress window. The window unit is specified to meet or exceed Ontario Building Code requirements for emergency egress.
Permit Application
Building permits are obtained for the foundation wall modification. If the enlarged opening affects load-bearing capacity, a structural engineer provides the required design for a lintel. Permit drawings include window dimensions, well specifications, and drainage details.
Interior Preparation & Dust Control
The interior work area is protected with dust barriers and floor coverings. Furniture and belongings are moved clear of the window area. Dust containment is critical during concrete cutting to protect the rest of the finished or living space.
Foundation Cutting & Window Installation
The existing window is removed and the concrete opening is enlarged using diamond-blade saws. The cut is made precisely to the required dimensions. The new egress window frame is set, levelled, shimmed, and secured. Spray foam insulation fills the gap between the window frame and concrete, and interior and exterior trim is applied.
Window Well Construction & Drainage
Soil is excavated outside to create the window well space. The well structure (galvanized steel, precast, or stone) is installed and secured to the foundation. A gravel drainage bed is laid at the bottom, connected to the weeping tile system. A window well cover (clear dome or grate) is installed to keep debris and water out while allowing light in.
Restoration & Final Inspection
Interior drywall around the new window is repaired and finished. Exterior grading is restored to direct surface water away from the well. The installation is inspected by municipal building officials to confirm code compliance. The completed egress window delivers safety, light, and ventilation.
Why Weston Homeowners Choose Us
Legal Bedroom Compliance
Egress windows are mandatory for any basement bedroom under the Ontario Building Code. Without a code-compliant egress window, a basement room cannot be legally classified or marketed as a bedroom, affecting both rental suite approval and resale property value.
Life Safety Protection
In a basement fire, a properly sized egress window can be the difference between escape and being trapped. It provides a critical second exit path when stairs may be blocked by smoke or flames, protecting your family and any tenants in a basement suite.
Dramatically More Natural Light
A single egress window provides 200 to 300 percent more natural light than a standard small basement window. The transformation is immediately noticeable — the room changes from a dim, artificially lit space to a bright, naturally illuminated room that feels welcoming and comfortable.
Improved Ventilation
Larger operable egress windows allow significantly more fresh air circulation than small fixed or slider basement windows. This natural ventilation reduces musty basement odours, lowers humidity, and creates a healthier indoor environment.

Basement Egress Windows FAQ for Weston Homeowners
How much does an egress window cost in Toronto?
A single egress window installation in Toronto costs $3,500 to $7,000 including the window unit, foundation cutting, window well, drainage, and interior finishing. The cost varies based on the foundation wall material (poured concrete vs. concrete block), wall thickness, depth of excavation required, and the type of window well selected. Multiple window installations typically benefit from per-unit cost reductions. Premium window wells with stone veneer or decorative finishes add $1,000 to $2,500 per window.
What size does an egress window need to be in Ontario?
The Ontario Building Code requires an egress window to provide an unobstructed opening of at least 3.8 square feet (0.35 square metres) with no single dimension less than 15 inches (380 millimetres). The window sill cannot be higher than 3.3 feet (1 metre) above the finished floor. Common egress window sizes that meet these requirements include 48 inches wide by 24 inches tall casement or slider windows. We specify windows that comfortably exceed minimum requirements to ensure compliance and maximize light entry.
Do all basement windows need to be egress windows?
No, only bedrooms are required to have egress windows under the Ontario Building Code. Basement living rooms, recreation rooms, bathrooms, and utility areas do not require egress windows, although they benefit from larger windows for natural light. If you are building a legal secondary suite, each bedroom in the suite must have its own egress window. We recommend egress-sized windows wherever the foundation allows, even in non-bedroom areas, for the light and ventilation benefits.
Can you install an egress window in a poured concrete foundation?
Yes, poured concrete is the most common foundation type in the GTA and is well-suited for egress window installation. Diamond-blade saws cut cleanly through poured concrete to create the required opening. The process is louder and produces more dust than block wall cutting, but the result is a clean, precise opening. Concrete block foundations are also compatible with egress installations. We handle both foundation types and adjust our cutting method and dust management accordingly.
Do I need a window well cover?
Window well covers are strongly recommended and included in our installations. They prevent debris (leaves, snow, garbage) from accumulating in the well, keep animals from falling in, and reduce rainwater entry. Clear polycarbonate dome covers allow light through while providing protection. Grate-style covers allow ventilation while keeping debris out. The cover should be easily removable from inside in case of emergency — permanently sealed covers defeat the egress purpose of the window.
