Double-Glazed Windows Replaced? Windows in South Wales

Customers in South Wales often ask us how frequently double-glazed windows need to be replaced. The answer is that it depends since there are many factors to consider.

Generally, high-quality and well-maintained uPVC double-glazed windows should be replaced every 20 years or so. However, this is only an estimate. Modern double glazing will probably last longer than double glazing installed a few decades ago. It is important to note that when we say “20 years or so,” we are referring to the lifespan of double-glazed uPVC windows. However, when it comes to replacing double-glazed windows, there are many other factors to consider. Let’s have a look at some of them:


Trends come and go, and double glazing is no exception. The first generations of double-glazed windows had many advantages, but they focused more on functionality than aesthetics. Today’s double glazed uPVC windows South Wales come in a plethora of styles and colours. Modern double-glazed windows can also emulate traditional styles and provide clean aesthetics for modern houses. All of this means that if you want to improve the appearance of your home in South Wales, replacing your double glazing is an excellent way to do so.


Original double glazing was far superior to single glazing in keeping out cold and draughts. However, the technology in today’s double-glazed windows is constantly improving. Even windows installed in 2015 may be inefficient compared to windows manufactured in 2022. To lower your heating expenses and carbon footprint, consider replacing your double glazing. If you notice that your house is draughtier than it used to be or that it has condensation, you should consider replacing your double glazing. If your furniture is aging in the sunlight, replacing your double glazing with new double glazing with UV-filtering glass may be an option. In summary, if your double glazing is not performing as effectively as it should, it may be time to replace it.

Quality of installation

Your current uPVC double glazing windows are only as good as the installation. Window and door installations are a huge investment, and the installation must be of the highest quality to ensure years of trouble-free use. If your existing double glazing was poorly installed, it is probably time to replace it.

The Best Time to Replace Double Glazed Windows

Upgrading the double-glazed windows in your South Wales home is a matter that must be addressed immediately. However, if you can wait a little longer, there is a “best time of year” to replace your windows. Window contractors’ schedules are much less congested during the winter, allowing them to pay more attention to the matter. You may also be able to negotiate a slight discount because they have less work.
