Cossins Windows and Doors will:

  • Schedule the final measurement meeting with you at which time all of the openings in your home receiving new windows and/or doors will be measured for manufacturing;
  • Review the installation process with you so that you are well informed regarding the entire process;
  • Confirm if any permits are required for your specific project.

Because we build your windows specifically for your home, if you wish to make any changes to your window or door order – the final measurement meeting is the time to do so.


The Cossins Windows and Doors installation team will co-ordinate the manufacturing, delivery and installation of your new windows or doors to ensure the project is completed on time and budget.


The Cossins Windows and Doors installation team will require access to both the inside and outside of each window and/or door opening. Please allow for the following:

  • Cleared work area on the inside of the home
  • Removal of any and all window treatments
  • Trimmed hedges and shrubbery
  • Acknowledgement that flower beds may incur some unavoidable damage (although we really try to be mindful of your flowers)
  • Removal of security system contacts attached to existing windows and doors being replaced


In order to fulfill our promise of a proper and professional installation, Cossins will require a few accommodations necessary to keep your home, family, your new windows and doors, and our crew safe before and during the installation process.

  • If possible, please allow for the parking of our vehicles in close proximity to the work site to ensure safe transport of your Cossins windows and doors.
  • Access to a standard 110-volt electrical outlet.
  • For their safety and that of our crew, please keep children and pets at a safe distance from the work area.
  • We utilize equipment to keep homes clean during and after standard installation but we recommend that customers with jobs requiring wall/structure modifications to cover furniture and belongings, as some dust is unavoidable.

Additionally, installation of windows in our Calgary winters can be a challenge.  We follow an installation process during the winter months in which we limit your home’s exposure to the elements.


Our superior installation process of your Cossins windows and doors involves more than just inserting the window in the opening. The Cossins Team will walk you through post-installation procedures aimed at putting the final touches on your replacement windows and doors and making sure that you are completely satisfied with the job.
