I went through this exact situation not too long ago, also in Calgary. At first I wasn’t sure if it was worth the investment, but honestly, replacing the windows changed the comfort level in the house more than I expected. No more cold drafts, rooms heat up faster, and the temperature stays more consistent. The most important part is choosing windows made for colder climates and installers who understand local weather conditions. When I was researching, I found
replacement windows in Calgary really helpful for getting a clear idea of options and what to expect from the process. Looking back, I wish I’d done it sooner.
