Old Double-Glazing vs New: Is New Double Glazing Worthwhile?

If the double-glazing on your property is looking a little tired or is getting old, you may have begun to look at replacement windows. But is it worth your time and investment replacing your old windows?

Let’s have a look at some of the reasons you may want to replace your windows and some of the key benefits to new double glazing. 

Why replace old windows? 

Aside from getting a great new look for your home, there are several reasons why you would want to consider replacing your old windows: 

Broken or damaged windows

 Over time, through exposure to the elements and simple wear and tear, your window frames and the mechanism will become worn or damaged. If your windows are difficult to close there may also be a security risk. Wooden frames are also prone to rot, if not cared for properly. Smaller areas can be repaired, but if your windows are displaying larger cases of rot, you will certainly want to consider replacing them. 


If you’ve noticed water creeping in through the gaps between your window frame, that’s a sure sign that your windows need to be replaced. While this issue can be repaired, if your windows are getting on in years, replacements may be the better option. 


While condensation on the inside or outside of your windows is normal, condensation that appears between the window panes in your double glazing is a sign that the window unit has failed and will need to be replaced. 

A sudden spike in heating bills 

If you’ve experienced a sudden, unexpected rise in your heating bills, there’s a good chance your windows are not performing as well as they once did. This could be due to draughts through damaged window frames and while this can be addressed with a simple repair, if the issue is appearing in multiple places around the home, you will certainly benefit from replacing your windows. 

Benefits of New Double Glazing

Even if your windows do not obviously need to be replaced, there are a number of key benefits to replacement windows, particularly if your windows are more than 10 years old. 

Improved Insulation 

Newer windows carry the latest technology which means they provide far better energy efficiency than older versions, even if the older windows are not damaged. Not only will this keep your home warmer, but it will also work to reduce your heating bills. 

Improved soundproofing 

Again, newer technology means that newer windows perform better from a noise reduction perspective. This is particularly useful if you live in a noisy neighbourhood or near to a main road. 

New Look 

When we think of uPVC windows, we generally think of the traditional white finish. However, there are now a number of different styles and finishes on the market. Whether you’re looking for a rustic French window effect or a traditional wood-effect finish, you can find the right look to suit a wide range of homes.
