Can double glazing be repaired?


If you have broken or cracked glass in your double glazing, this can be replaced without the need for a whole new door or window.

You may have noticed condensation has started to form between the panes of glass in your double glazed windows. When this happens, it is a sure indicator that a part of the unit has failed. This is most commonly down to damage to the sealant, which allows the warm air in your home to escape into the gap in your double glazing. When this happens, and the warm air hits the colder outer window, condensation occurs.

What is double glazing?

First of all, double glazing is made up of 2 separate panes of glass with a space in between. Most often, the gap between each pane of glass is filled with argon, an inert gas that is a poor conductor of heat. When all these components are put together, the glass combined with the argon-filled space creates a barrier between the outside and inside, preventing draughts and making your home more thermally efficient.

There is condensation in my double glazing, can it be fixed?

The double glazed unit can be replaced in your existing frame, meaning you will not need to buy a complete new window or door. We would dispose of your old glass and offer a guarantee on your new double glazing.

Why is there condensation in my double glazing?

Double glazed units are sealed to prevent the argon gas inside from escaping. Most commonly, if windows have been poorly fitted, or not maintained, this seal can fail which results in the gas escaping. When this happens, the space between the two panes of gas isn’t airtight and the warm air in your home rushes into it.

Time can also damage the airtight seal on double glazed windows. This happens because as the temperature both inside and outside fluctuates, the glazed unit expands or contracts. When this happens, the seals can become damaged and loosen. Furthermore, some cleaning products can damage seals, particularly chemically abrasive ones.
