What are the telltale signs your double glazing needs replacing?

As a leading glazing supplier, we are often asked how to tell if double glazing needs replacing. The life span of double-glazed windows is typically between 15-20 years but this can be impacted by window quality, installation, maintenance, and other factors such as weather conditions.

In this article, we will provide some useful pointers to help you decide when to replace double glazing and offer guidance on the next steps.

The 6 major signs your double glazing needs replacing

If you’re wondering how to tell if double glazing needs replacing then this quick checklist should help.

On inspecting your double glazing, is there:

condensation on a glass window. signs that your double glazing needs replacing.

  1. Condensation between panes – foggy or mistiness indicates that the seal has failed. If this has happened then the inert gas that sits between the two panes will have escaped and been replaced with moist air. This means that the window’s ability to retain heat is compromised. The condensation and lack of clarity are also quite unsightly, so we would always recommend replacing blown double glazing.
  2. Rot or major cracks – any significant areas of rot or large cracks leave your property at risk of mould or damp ingress.
  3. Leaks – if the seal around the frame has worn away then you might notice that your window begins to leak. If the leak is large then we would recommend that you consider replacing double glazing units.
  4. Draughts – if the window seal has failed, cold air will make its way into your home. This also means that heat will make its way out. Replacing window seals is possible but it is not an ideal solution.
  5. Noise – if there’s too much environmental noise coming into your home then it is recommended that you replace your windows.
  6. Difficulty opening and closing – sometimes this issue can be due to faulty hardware but it could also be symptomatic of a bigger problem with your window’s integrity.

Although a little bit of wear and tear is to be expected over time, if the function and performance of your glass, frames or fastening/locks is compromised then these are some of the telltale signs your double glazing needs replacing.

While a repair may seem more appealing than a replacement, if your windows are approaching the 15 to 20 year mark then it is unlikely to be a cost-effective solution.
