Double glazing has been standard in new UK properties since the 1980s, though, as you can imagine, the quality of these windows has improved significantly over the last 30 years. Even if your house has double-glazed windows, they might be past their best and now be ineffective at keeping the cold out. Here’s how to find out whether it is time to repair or replace your windows.
- Over 25 years
Double-glazed windows typically last between ten and 35 years, but this depends on the quality of the glass, how well they were fitted, and if they have been properly maintained. Over time, the gas between the panes will leak out, which means the insulation will be less effective.
If you know your windows were installed over 25 years ago, it is worth considering replacing them as modern models are likely to be much more energy-efficient, saving you money on energy bills.
- Water leaks
Homeowners who can see water leaking through their frame should call double-glazing repairmen straight away, as this is a clear sign the seal around the window is no longer working properly. This means it will not be able to keep out inclement weather during heavy bouts of rain or snow, causing the temperature in the house to plummet and moisture levels to rise.
- Cracks in the glass
It is necessary to replace the glass in the windows if you spot any cracks or chips in it. A small dent can lead to a larger break if left unfixed, and this will result in leaks or a draught coming through the window.
- Condensation
Double-glazed windows are made up of two panes of glass, with an insulating gas trapped between them. This prevents air flow through the glass, keeping heat in and cold out. However, if you notice condensation between the panes, this is a sign the seal is no longer working and the gas is coming out of the windows, unable to prevent heat from escaping from the house.
