Egress windows are basically used as emergency exits in case of fire or other when other hazardous situations occur. Even though these windows are not a new concept, the standards and regulations associated with their installation, usage or location are quite complicated and should be strictly followed when installing.
At Ecoline, we always strive to educate our clients to decide whether an egress is necessary. If it is a rental property and the room is supposed to be used as a bedroom, then egress is definitely required. If there is no such window, regulations will prohibit a basement bedroom. So let’s take a close look at what the regulations are now and what else you should know about egress windows in Calgary.

When it comes to windows in basement bedrooms, they should have better access. For instance, built-in-furniture below the window may be installed.

How To Install New Egress Windows In Calgary
Installing new egress windows doesn’t have to get complicated or anything.
You will need some tools to achieve this; some tools you will need are Shims, Moisture barrier (plastic), galvanized screws, deck screws, tarp, and other necessary tools.
It is subdivided into cutting and installation.
This is the first part of installing Egress windows. First, measure out the length that your egress window should have; make sure to leave drawing marks for the next part of the job. The next part of the job includes making the same drawing line on the other side of the wall, thereby making it 2-dimensional.
Dig a well outside of the place you are situating the Egress window, then get down to cutting
Selecting a concrete saw, use it and drill through the mark you made but use it only to drill half the distance on the other side of the wall, then move over to the other side to complete the cutting.
If you followed these instructions, then you should have an egress sized cut space in your wall or basement in your Calgary home where you can proceed to install your egress window.
Clear out the remaining rough edges around the hole you just drilled; you can use a brick chisel to do this.
Then, use concrete to stuff up the places where there are holes or empty bottom blocks.
Put your window frame in the space you drilled and use deck screws, ceiling plates, or joists to fit it to the wall. If you have any exterior caulk, then apply it to create a waterproof region to your egress window.
Now you can finally install the window. Egress windows typically come with a voluminous instruction manual that will guide you on installing them very well. That’s it.
Window Wells in Calgary
A window well is usually a U-shaped metal or plastic product designed to fit around the doors of your basement; they sit between your window and the ground, and their functions include keeping soil moisture out and serving as emergency exits just like window egresses. In case your basement windows are not currently equipped with window wells, you are supposed to have them built-in. This is a requirement by the NBCC (National Building Code of Canada). The process requires either equipping a window well where is it absent or widening your current window well in order to follow the size requirements, which go as follows:
- A clearance distance of at least 22 must be present between the window and the window well.
- An affixed permanent ladder or step must be present with windows with wells with a depth of 44 or bigger to get an uncomplicated and safe escape route in case of any emergency.
- A 6′′ of drainage rock needed as well. 6′′ of clear space from the bottom of the window to the drainage rock and a need to core down to the footing and install a drainage pipe. In addition, some homes that are at lower risk for flooding or were built a long time ago may not have a Weeping Tile installed. If a home is experiencing basement seepage, the lot owner should confirm that Positive Lot Drainage is provided and maintained and that roof drainage best management practices are applied. If basement seepage problems persist, a Weeping Tile system may be a tool to improve foundation drainage which can be pursued following consultation with a Building Envelope specialist.
Depending on the type of window well you are buying or installing, the prices can range a bit. However, the typical price range is $30-$80 depending on window well brand and materials. To get a better idea as for the current prices give a look at your local shops like this.
- Excavating: At this point, you excavate a hole large enough to size the well you bought after taking measurements.
- Creating a Drain Hole: You can use augurs to develop a bore to size your window well; after doing that, you can use a perforated tube to divert water from the well to your house’ drainage system.
- Installing the window well: While installing the well, you must make sure that some part of it is well above the ground; 3 or 4′′ is just fine. Make marks on the already existing hole on your house’s foundation and drill 2′′ holes on them. This is where you are going to screw the window well.
- Finishing up: Using nuts and anchor sleeves, screw the window well into holes as mentioned above to secure it, then fill the outer edges with gravel and then put a cover over the window well.
