How do I know if my double-glazing needs replacing? - Jewel Windows

Double glazing, no matter how well made, can’t last forever. Like everything in life, they have a shelf life, even when sourced from leading companies and installed by professionals. In general, double glazing will last between 15 and 20 years on average.

How long your double glazing actually lasts being it needs replacing will depend on a variety of factors including the materials used on the profile, the weather conditions and how well you care for your double glazing.

If you have double glazing windows and doors installed in your property, you need to be aware that they will need to be replaced. If left, they can seriously affect how your home performs and how much it costs to run. Luckily, you don’t need to rely on guesswork as there are a lot of crucial signs which will let you know that your double glazing needs replacing.


Are There Draughts?

One of the key signs that your double glazing needs replacing is that your home is harder to keep warm. Older windows and doors can get draughty, this is because the seals around the double glazing has worn away. Draughts will come through the gaps in the brickwork of your home and the sealants will naturally wear away over time.

Although you can simply replace the weather seal, it may be more cost-effective in the long run to replace your double glazing completely. Draughts won’t just make your home colder but it means the warmth generated by your central heating will be wasted.

Chips Or Cracks In The Window Pane

Rise of Condensation

Condensation is more than just an inconvenience; it can be detrimental to your home and your health. Condensation is the process of vapour or gas transforming into liquid. When the temperature of glass falls below the dew point temperature of the air in the surrounding area. The water vapour found in that air will turn into those droplets of water we call condensation.

Condensation happens in muggy heat and cold conditions. It may seem a minor issue, but it’s actually a sign that the seal between the two sheets of double glazing has developed a leak. It means the gas cavity is no longer sealed between the two panes.

In small amounts, most people should be okay but if the condensation is allowed to build up in your home and mould begins to form, it may cause health issues. This is why it’s important when condensation becomes a minor problem you resolve it before it becomes a bigger and more expensive issue.
