When done right, double glazing delivers a perfectly neat, flawless finish. Despite existing as two panes of glass, the window should appear crystal clear, modern and non-bulky. They
provide a remarkably energy efficient solution without compromising on style in any way. However, there are instances where double glazing does not achieve this high-quality finish.If the double glazing installers made a mistake when fitting, or if wear and tear has caused the windowpane seam to break down, then there can be visible issues with the unit.
In this article, we will be sharing the top causes of failed or misted double glazed units. That way, you can understand what has caused these failings, then follow the best course of
action to fix them.

What do misted double glazed units look like?

One of the most common visible failings that we see in faulty double glazed units is misting. You can tell that your double glazed unit is misted by looking for signs of condensation on
the inside of the windows. These spots of moisture or patches of misting occur in between the two windowpanes, in the gap of air that is left between them.

What are the most common causes of failed double glazed units?

This misting is caused by condensation seeping in between the two panes of glass. However, obviously this is not what was intended for the double glazing unit, so what has caused it?

Well, this unit could have failed for a number of reasons. The most likely reasons for condensation to appear in between the windowpanes are:

• Broken or faulty windowpane seals – a failed seal can allow moisture to get through the unit and collect in the space in between the two panes of glass.
• Gradual wear and tear – after a long period of usage, the seal can break due to age.
• Issues with installation – if the double glazing installer did not correctly fit the window or apply the seal, then this can cause faults to quickly appear. In fact, if the installation was faulty, then signs of failing can appear in less than a year.

Our top tips for avoiding double glazing misting:

In the case of age or gradual wear and tear, there are things that you can do to prevent (or delay) this problem from arising:

• Only ever use professional, qualified double glazing fitters and repair specialists, with a full set of industry accreditations and quality standards
• Carefully maintain your windows. Clean the seals regularly, to prevent the buildup of damp and dirt.
• Avoid using strong solvents or any oil-based cleaning products on your window seals.

What is the best way to fix failed double glazing?

If you spot signs of failure or moisture within your double glazing units, then the best way to fix it, to prevent the damage from escalating, is booking a repair with double glazing specialists.
If the issue with your double glazing was caused by a poor installation, then you should request a refund from the installer. Hold on to all of the paperwork (including warranties, contracts and proof of payment) between you and the fitter, as this will help you to make your case.

Then, once your refund has been processed, enlist the services of a more trustworthy double glazing installer.
