Basement Window Replacement and Egress Windows in Toronto
Replacing a small basement window is one job. Cutting a larger egress opening for a bedroom or suite is another. Know which one you need, then connect with qualified Toronto professionals.

What to expect
Replacing a Basement Window vs. Adding an Egress Window
Daylight and a safe exit turn a cellar into a home. The two jobs are related, but not the same.
Like-for-like replacement
Swapping an existing window for a new one, sized to the current opening, and sealed against water and air.
New or larger opening
An egress window usually means cutting the foundation wall, with structural care around lintels and pipes.
The window well
A well outside the window with drainage, so it does not collect water against your foundation.
A safe way out
Ontario’s guide explains that escape windows can be required where exits pass through other units.
Permits
Toronto Building lists new windows and relocated openings among work that needs a permit.
Finishing
Insulation, air sealing and interior finishing around the opening.
Basement Window Cost: What Moves the Number
People search for egress window installation price and basement egress window cost because the range is wide. Reno Rise does not publish prices, but here is what moves the total:
Whether it is a like-for-like replacement or a new, larger opening.
What is in the wall: structure, lintels, pipes and wiring.
The window well, its drainage and any stairs or ladder.
Permits, drawings and inspections where required.
Interior finishing and air sealing.
Window Timeline Expectations
A like-for-like window replacement typically takes a day. Cutting a new or larger egress opening, building a window well and finishing the interior typically takes a few days to about a week, depending on what the wall turns out to contain.
A permit, where the scope requires one, is arranged before the foundation is cut.
Hitting structure, pipes or wiring inside the wall can extend the job once it is opened up.
Window well drainage work takes longer where the surrounding grade needs regrading too.
Weather can affect exterior excavation for a window well.
Common Mistakes Homeowners Make
Basement window projects go wrong in a few predictable ways:
Assuming a like-for-like replacement and an egress window are the same job and the same price.
Not confirming the window well will actually drain before it is built.
Skipping a permit check for what looks like “just a window.”
Not asking what happens, and who pays, if the opening hits a structural element or a buried service.
Choosing a window and well based on looks alone, without confirming it meets the Code requirement for the room.
Finding Basement Window Installers in Toronto
Whether you are after basement window replacement near you or a full egress upgrade, ask the same basics before hiring.
Will this window and well meet the Building Code for this room in this house?
How will the well drain, and what happens in heavy rain?
Who applies for the permit and arranges inspection?
What happens if the opening hits a structural element or a buried service?
Permits and approvals
Toronto Building includes new windows and structural or material changes among work that needs a permit. Toronto Building lists underpinning, structural or material changes, new windows or doors, constructing a basement entrance, heating or plumbing changes and adding a second dwelling unit among the work that needs a building permit. Confirm what applies to your project.
Questions to ask a professional
Will the window and well meet the Code requirements for this room and this house?
How will the well be drained so it does not collect water against the foundation?
Who applies for the permit and arranges inspection?
What happens if the opening runs into a structural element or an old pipe?

Frequently asked questions
What is an egress window?
An egress window is large enough, and reachable enough, to be used as an emergency exit. In a basement it usually means an enlarged opening and a window well.
Does a basement bedroom need an egress window?
Bedrooms need a safe way out, and Ontario’s guide describes emergency escape windows for certain layouts. What applies depends on your design, so confirm with a designer and Toronto Building.
Do I need a permit to replace or add a basement window in Toronto?
Toronto Building lists new windows and relocated openings among work that needs a permit. A like-for-like swap is different from cutting a new opening, so describe your exact work to the City.
How much does a basement egress window cost?
It depends on the size of the opening, the wall, the window well, permits and finishing. Reno Rise does not publish prices. Get itemized quotes from more than one professional.
How does a window well drain?
A window well is built with drainage so it does not collect water against the foundation. Ask each professional how theirs will drain in heavy rain.
