Hi everyone! I’m planning to replace several old windows in my Calgary home, and I’d love to hear from people who’ve gone through this process already. My current windows are over 15 years old, and during winter it feels like cold air literally seeps through the frames. I’ve spoken to a few installers, but every company seems to offer something different — different glass packages, warranties, installation methods, and price ranges. It’s honestly overwhelming.
What I’m trying to figure out is what actually matters most when choosing a window replacement company in Calgary. Should I focus more on the energy rating? The actual installation crew? The type of frame? Also, is there really a noticeable difference in comfort or energy bills after the replacement? If you’ve had your windows replaced recently, I’d love to hear your experience and whether you’re happy with the results.

I went through the same thing last year, and I get how confusing the whole process can be. After talking to a bunch of companies, the best experience I had was with a team that specializes specifically in Calgary windows What impressed me was how clearly they explained what actually matters for our climate — things like proper sealing, energy-efficient glass packages, and frames that can handle Calgary’s dramatic temperature swings.
Their consultation was super detailed: they walked me through the pros and cons of different window types, didn’t try to push unnecessary upgrades, and were transparent about pricing. The installation team was also great — they protected my home, worked efficiently, double-checked every seal, and cleaned up afterwards.
The difference after installation was huge. The drafts disappeared, the house stayed warm even on those crazy cold mornings, and I actually noticed a drop in heating costs. If you want something that lasts and performs well in Calgary conditions, choosing a company that really understands the local climate makes all the difference.

This really helps — thank you so much!
