The function and style of the windows in your home account for so much. With old, less energy-efficient windows, you may deal with more than just an outdated aesthetic. In addition, you’re combating higher energy costs. These days, you can get the best of both worlds, though. Today’s windows are built to lock heat inside through the winter months. They’ll also ensure your home stays cool on those hot summer nights. On top of this, a window replacement will add value to your home and give it a fresh look you’ve been dreaming of.

Thank you, Active Exteriors for making my home beautiful again. The staff went out of their way to make sure that everything was done to my satisfaction despite the difficulties of getting supplies which is totally out of their control. The excellent quality windows were installed in very professional and timely manner. They made sure everything lined up and looked good. John’s siding crew did an awesome job in the sweltering heatwaves. They were very professional and courteous answering all questions about the Hardie Board siding with patience and knowledge.

When a new window was needed, Window Seal West really came through. From the first appointment with their Project Manager, Max Mateisen, to the visit for measuring, and finally the installation, they were always on time and efficient. The installers functioned like a well-oiled machine, and the drop cloths they put down to protect the floors were really appreciated. The installation itself took the amount of time they said it would, and the window looks and works great! I’m pleased to be able to shop local since they have their own manufacturing facilities here in Calgary, and am looking forward to working with Window Seal West later this year to replace the remainder of the original windows in the house.
