Basement Egress Experts
Egress Window Installation in Ottawa
Complete egress window installation in Ottawa from excavation and concrete cutting to drainage, waterproofing and finishing.
One contractor for the entire project
An egress window is several jobs in one: cut the concrete, dig the well, install the window, and waterproof the whole thing. Egress work often requires several trades — TOXX coordinates and completes the major stages under one team, from excavation and concrete cutting to drainage, waterproofing, and finishing. One contractor, one quote, one company accountable for the finished result. That’s the point of hiring a specialized construction contractor instead of a window installer.

Our Process
What an egress installation includes
- Site assessment and exact opening measurements
- Concrete cutting of the foundation opening to the required dimensions
- Excavation of the window well to code depth and clearance
- Window supply and installation
- Window well installation with proper drainage
- Waterproofing of the opening, well, and surrounding wall
- Backfill, grading, and site cleanup
Every installation is built to meet the Ontario Building Code requirements for egress windows. The exact requirements — minimum opening sizes, well depth and clearance, permits — are covered in our egress window requirements guide.
What to expect
- We visit and measure. Free estimate. We confirm the opening size your basement needs, check the foundation, and tell you exactly what the job involves.
- We cut and dig. Many installations are cut and excavated in a single visit. We protect your home from dust and debris during cutting.
- We install and waterproof. The window and well go in, everything is sealed and waterproofed, drainage is connected.
- We backfill and clean up. The site is graded, debris is removed, and you’re left with a finished, code-compliant egress window.
Many residential installations run a day or two from start to finish — you’ll get a clear timeline with your estimate.
Ottawa’s clay soil and freeze-thaw cycles are the reason window wells fail here — soil pressure and spring melt push water straight at the well if the drainage isn’t done right. That’s why waterproofing and drainage are part of our egress installations, not an afterthought. We install year-round and serve Ottawa and surrounding communities, including Kanata, Nepean, Orléans, Barrhaven, Stittsville, Manotick, and Navan. Wondering about price first?

Egress window FAQs
Does my basement bedroom legally need an egress window in Ottawa?
Yes. The Ontario Building Code requires every bedroom to have at least one code-compliant emergency exit window. Without it, the room can’t legally be called a bedroom — which affects insurance and resale value. The full code breakdown is in our requirements guide.
How much does an egress window cost in Ottawa?
It depends on excavation depth, the size of the opening, and the concrete cutting involved. We’ve written a detailed cost guide — and every quote from us is free.
How long does installation take?
Many residential installations run a day or two: cut, excavate, install, waterproof, backfill, clean up. You’ll get a clear timeline with your estimate.
Will my window well leak?
Not if it’s built right. Waterproofing and drainage are part of every installation we do — that’s the advantage of having the cutting, excavation, and waterproofing handled by one team.
Can you install an egress window in winter?
Yes. Interior cutting is weather-independent; we schedule excavation around conditions. Winter installations are common.
Do I need a building permit for an egress window?
Cutting into a foundation wall is structural work, and the City of Ottawa typically requires a permit for new egress openings. We’ll tell you exactly what’s needed for your address before we start.
