Windows Calgary Comparison: Lux Windows vs Gienow Windows [2025]

Nothing is good or bad, but by comparison.

This statement, first said almost four hundred years ago, couldn’t be any more true today. And it is particularly true about your window replacement. Sure there are shady window companies and ones that have revolutionised customer service with their high standards of excellence. But overall, whether you’re replacing your windows, buying a new car or trying out a new restaurant your experiences and opinions will be entirely subjective.

That isn’t to say they’re worthless. In fact, a smart buyer like yourself (you are taking the time to educate yourself after all) can use these subjective opinions to your advantage, to decide which companies you should or shouldn’t get a quote from.

Just like potential customers, we spend quite a bit of time doing research on Canadian window companies. Why? Because while Calgary homeowners are happy with their custom window solutions in different ways, when they are unhappy it tends to be for all the same reasons. Doing research helps us identify common areas of concern, and hopefully improve on them in our business so that we don’t make the same mistakes as other companies do.

So today we are reviewing two preferred window brands among Calgary residents – Lux Windows and Gienow (now part of Ply Gem).

WARRANTY
Gienow being part of Ply Gem offers a window warranty for twenty years. As professional window installers in Calgary, the company has little to no questions when it comes to warranty issues, offering a great customer service if any issues arise.

Gienow is a perfect example of the subjectivity of online reviews. The customer ratings on Homestars run across the map from 0s to 10s. This doesn’t necessarily put them in a bad category, as true origins and motivations behind online reviews in general are often questionable. Most often, customers cite issues with the product itself, or problems as a result of improper window installation.

To a potential window customer this may pose quite a dilemma. Do you go for great product with potential service issues, or do you risk going for a lesser product with excellent service? Ideally you would want both, but nothing in this world is perfect.

We’ve taken great strides in the last couple of years to address the issues we had with our windows Calgary service requests. By working with our clients, we’ve learned that the happiest customers aren’t the ones without any problems, they’re the ones that feel like the company has taken care of them.
