4 Reasons To Install Windows During Winter


Hello dear friends, with the official first winter day being only a few weeks away from us, I think it’s a good time to talk about winter windows installation.

Unfortunately, window replacement in the winter is surrounded by so many myths that drive away many homeowners.

We covered 7 widely spread myths about window replacement in our previous blog post.

It may sound surprising to you, but many people consider winter the worst time to replacing windows because of, as they say, cold weather.

Fascinating fact,

The annual count of frost days, when the minimum temperature is less than 0ºC, has decreased, on average, by 17 days from 205 to 188 for the past 67 years in Calgary; the future scenario, we might expect the 30-year average of frost days will be 157 days between 2041 and 2070 in Calgary.

Winter is getting warmer, and so do we get more days now to enjoy the work outside.

Many people are not aware that the winter windows installation process is similar to summer windows installation, with only a few minor exceptions.

We're going to cover this and other aspects of winter window replacement in today’s blog post.

Read on to learn why we think winter is the best time to replace old windows.

Difference between summer and winter windows installation

The first question that comes up to mind is,

when is the best time of year to replace windows?

Summer is typically a more appropriate time to replace your windows because the days are longer and warmer, and the installation process is faster.

However, in winter, we get only seven to eight hours of daylight, which is not a lot when you work on a big and complex project.

So, in this case, summer would be the best time to plan any major projects.

However, if your project is split into multiple phases, and you only plan to replace one floor or room at a time, then winter will be ideal to realize your project.

One major downside of the windows replacement in the summer is that you will fall into the peak season—which is when the companies experience high volume in customers, sales, and work.

In Alberta, the peak time usually falls between mid-March and late April, with the second peak falling between early September and mid-October, right before the thermostat temperature drops to a minimum.

Because a waiting period is between four to six weeks from the initial quote to allow your windows to be manufactured and delivered, your actual scheduled installation occurs in June-August.

It’s not rare to experience delays with manufacturing, shipping, and installing the windows in peak times.

In such a case, winter is also a better time because of fewer delays in the project.

Certainly, an initial date for windows replacement might be moved because of weather, but overall we see the wait times for installing your windows to be shorter in the winter.

During winter, your energy consumption usually peaks on frosty days as reliance on the furnace increases, and so your energy bills.

If your windows are not fitted with good double or triple glazing, or they’re dilapidated, leaking and drafty, then your room will be comfortless and cold.

An over-working furnace can lead to issues with your heating system.
