Cuts made were clean and to the exact dimensions

Nothing but great things to say about Canwest. We had two basement windows enlarged and egress windows installed. The crew that performed the work was respectful & safe at all times. The cuts made were clean and to the exact dimensions, windows are installed and sealed to perfect, and the install of the well, gravel and clean-up looks as if no one was even there, except two nice big new windows ! Big thanks to the team over at CanWest!

Tyler and his team at CanWest did a perfect job

Tyler and his team at CanWest did a perfect job and we are very happy with the finished product. Had them complete an entry way through a cinder block wall in our warehouse. The job was done on-time and they left the place spotless when finished, all at a great price. Would definitely recommend.

Why do you need a permit to install basement windows?

Calgary has strict laws in place that requires homeowners to get permits for specific home renovations. Egress windows and any renovation that involves cutting into the foundation of your home, or could potential effect fire/building codes, will require a permit.

All measurements provided for the permit/work being completed will need to follow the Alberta Building Code.


Obtaining a permit

As the homeowner, you can pull the permit yourself, or for an additional administrative fee, CanWest can pull the permit on the homeowners behalf as the contractor. We are an approved company in many cities, towns, municipalities and complete work all across Alberta. 

For CanWest to pull a permit on your behalf, our team will require a:

  • Site plan
  • Basement floor plan
  • Elevation drawings
  • and the homeowners written consent that we have permission to pull a permit. 

If you would like to pull the permit yourself, please click here, to go to the City of Calgary were you can learn about the permit process and get started in getting a permit for your next project. 


Permit can take several days to be issued from the city. Once the permit has been obtained, and the work completed, you will need to call the number provided with the permit to have an inspector view the work completed.
