Condensation

If you have noticed condensation appearing between the sheets of glass, this means the seal on your window has started to fail, and you'll need to take action. Your window should last for many years before this becomes an issue, but it is common in older windows. You might first notice it on windows on the side of your house that gets the most sun, whilst windows on the opposite side of your house might end up lasting for several more years.

Even a very small leak can gradually lead to condensation appearing, meaning your double glazing is no longer working as efficiently as it should. Reputable double glazing providers such as Dublin windows and doors companies can supply replacement windows if yours are showing signs of condensation.

Visible damage

Windows to go through a considerable amount of wear and tear over their lifespan, and at some point, it's normal for them to start showing signs of damage. It's true that double glazing is tough and difficult to crack, but accidents can happen and a heavy blow could damage your window beyond repair. Tiny cracks or chips can sometimes be repaired without replacing the entire sheet of glass, but larger cracks will require a whole new window to be installed.
