Egress Windows in Whitby, ON

Installing egress windows is a great way of letting more air and light into your basement. Instead of being a damp and dark space, egress windows will make it a space for you and your family to enjoy and actually want to spend time in.

Another reason to install egress windows in Whitby is if you are planning to convert your basement into a secondary suite (or an accessory suite as they are referred to in Whitby). Having a basement that functions as a secondary suite is becoming increasingly popular across the GTA with rising prices and increased densities. Having an egress window in a secondary suite means that the occupants are able to use the window as a means of escape in the event of a fire or emergency.

Egress Window Requirements in Whitby

Many homeowners are under the impression that an egress window is a special type of window. In fact, any window can be an egress window as long as it meets the requirements outlined in the Ontario building code. For your window to qualify as a legal egress window it must meet the following conditions:

  • The window must have an openable area that is larger than 3.8 square feet. That means that you should only include the area of the glass in this calculation, window frame not included
  • The window must not have any dimension that is less than 15 inches (Also referring to the unobstructed openable area)
  • The window can be opened without the use of any special tools or knowledge
  • When the window opens into a window well, the well should have an unobstructed clearance of at least 22 inches.
  • If the window well has a cover, it must be openable without the use of any special tools or knowledge
  • It is recommended that the window is not more than 40 inches above the basement floor but that requirement can usually be accommodated by placing a piece of furniture under the window


As long as a window follows the requirements outlined above, it can qualify as a legal egress window. Sometimes egress status can be accomplished without having to enlarge the wall opening (for example by converting a slider window with a casement window with a retrofit installation). If you are unsure whether your window needs to be replaced or enlarged, give us a call for a free consultation.

Egress Window Installation Process


When you call us to schedule a free estimate, we will send out one of our certified estimators to help understand your needs for the project. Once we get an idea of what you would like to accomplish, we can make suggestions and work out the best way to complete your project within your timeframe and budget. Once the details of the project have been worked out, we will write up a quote that outlines the work that will be done and the associated costs.


Once we agreed on the scope of the job, our expert installers will come to take precision measurements. They will also confirm that the job can be done safely and efficiently as explained by the estimator. The installer will also measure to make sure that all the sizes are in compliance with the Ontario Building Code and municipal regulations. The measurement process is quick and shouldn’t take longer than 10 minutes.


Our expert installers are insured and certified to the latest installation standards. Installing egress windows can be a complicated job especially when horizontal cuts are being made to the foundation of the house. In this type of installation, having installers that thoroughly understand the work and can perform it professionally is very important. You can usually tell a good installer apart from a bad one by asking if they are willing to do the work with a home inspector present. There are many opportunities to cut corners and many companies often do. Providing adequate support, seal and framing for the window can add to the cost of labour but is vital for the long term integrity of the window and preventing costly repairs in the future.


One of the important and often overlooked aspects of a proper installation is the cleanup. Removing soil, debris and other waste is important for both the cleanliness and safety of a job site. While a thorough cleanup can be time-consuming, we believe it is an important part of the project and we don’t leave the site until proper cleanup is completed.
