What is the price of a triple-pane egress window from Jeld-Wen installed in a GTA basement?

Egress window pricing varies significantly by project, but for a triple-pane egress window in a GTA basement, you're typically looking at $4,500–$8,000+ installed — and the window unit itself is only part of that cost.

A Jeld-Wen triple-pane egress window (casement or awning style, which are the most common egress configurations) will run roughly $600–$1,500 for the window unit alone depending on size, glass package, and where you purchase it. However, the window cost is almost secondary to the installation work in a basement egress project. Cutting through a concrete or block foundation wall, forming and pouring a new concrete lintel, installing a window well, backfilling, waterproofing the rough opening, and finishing the interior all add up quickly in the GTA market.

Here's where the real cost lives. Foundation wall cutting requires a concrete saw or core drill, which is specialized equipment. If your home has a poured concrete foundation (common in post-war Scarborough, North York, and Etobicoke bungalows), cutting the opening is labour-intensive and generates significant debris. Block foundations are somewhat easier to modify but still require structural consideration. A structural lintel — typically a steel angle or precast concrete beam — must span the opening to carry the load above. This alone can add $500–$1,500 in materials and labour. The window well (typically galvanized steel or polypropylene) needs to be large enough to meet Ontario Building Code egress requirements and allow a firefighter in full gear to enter — budget $300–$800 for the well and proper drainage gravel beneath it.

Ontario Building Code sets the minimums you cannot compromise on. The unobstructed opening must be at least 0.35 square metres (3.77 square feet), with a minimum width of 380mm (15 inches) and a maximum sill height of 1,000mm (44 inches) from the finished floor. These are life-safety requirements — the window must be operable from the inside without tools or special knowledge. Triple-pane casement windows from Jeld-Wen meet these requirements in appropriate sizes, and the triple-pane glass package is a smart choice for a below-grade application where thermal performance and condensation resistance matter. The energy performance difference between double and triple pane is meaningful in a Toronto winter, particularly on a north-facing foundation wall.

A few practical notes for GTA homeowners. First, a building permit is required for every egress window installation — this is a structural alteration to your foundation wall and the City of Toronto Building Division or your local municipality must inspect the work. Budget $500–$1,500 for permit fees. Second, the exterior window well needs a proper drainage layer (minimum 150mm of clear gravel) connected to your weeping tile system or a dedicated drain — without this, the well becomes a water collection point that funnels directly into your new window opening. Third, if your basement has a high water table (common near Lake Ontario in areas like the Beaches, Mimico, or Port Credit), the window well waterproofing detail becomes even more critical.

This is firmly in professional contractor territory. Cutting a structural opening in a foundation wall without proper shoring and a correctly sized lintel is genuinely dangerous — foundation settlement and wall cracking are real risks. All of this work requires a permit, and the inspection process exists to protect you. An experienced basement contractor will handle the structural assessment, permit application, cutting, lintel installation, window well, and waterproofing as a complete scope.
