What can you do if your double glazing is showing signs of wear?

1. Excessive Condensation

In the winter, when windows and doors are closed, condensation may form inside the glass panes if the air temperature is warmer than the window's surface. This is a natural occurrence that can be prevented by opening windows, improving ventilation more generally, running a dehumidifier and keeping moisture levels low with extractor fans. However, if condensation forms regularly on the interior of your windows this is a sign that the double glazing has failed and it needs replacing as soon as possible.

Condensation on the outside of your windows is normal and is a sign that the double glazing unit is operating just as it is supposed to. Condensation on the outside of your windows in the morning occurs because of the cold glass temperature falling below the dew point of air surrounding it, causing water vapour to be drawn up from the air into the cold glass, where it cools. This can be made worse by plants that generate excess moisture in your house and by high levels of humidity.

If you notice condensation in your double glazing, it is an issue that is more serious. It is a sign that your seal between the glass panes is broken. This allows warm air from your home to pass through while the insulating gas escapes. This could cause serious damage to the double glazing and should it not be addressed will greatly impact your energy bills.

Installing replacement double glazing as soon as this type of condensation is noticed can reduce the likelihood that it will worsen, saving you money in the end. It's also a great opportunity to upgrade your double glazing to energy-efficient A-rated windows. This will make your home more comfortable, and reduce your utility bills.

2. Signs of Wear and Tear

Double glazing can provide many benefits including cutting down on energy bills and also reducing noise. But, like every other type of window, double-glazed windows are not a lifetime product and it's important to be aware of the indications that they are nearing the end of their usefulness.

Draughts around windows are another indication that sealants have begun to wear. This lets outside noises into your home, which can be distracting. This could affect your ability to work from home or how relaxing your home feels.

3. Draughts

If you've noticed draughts passing through your windows, this is usually a sign that the seals within your double glazing have failed. Sealant is used to hold the glass panes and provide insulation. However, it could be damaged by weather changes or simply ageing. This allows cold air to enter your home and warm air to escape, leading to the draughts to increase and decrease energy efficiency.

A window frame that is not properly shaped and not sealing properly could also cause draughts. The moisture can also get caught in the window frame, causing the draughts to increase over time. This is a serious issue and it is essential to have your double-glazing replaced as soon as is possible to avoid any further problems.

Double glazing cracks and chips are not always a sign of needing to be replaced, but they may affect the overall performance. As well as allowing cold air to pass through, they can limit the amount of light that is allowed through and lead to drafts. If your windows have deep cracks or chips, they may not be strong enough to support the weight of replacement units and would require new window frames.

4. Higher Utility Bills

Energy costs are a major expense for fitter households and that's why it is essential to keep them as low as is possible. The high cost of energy is not only costly, but they also put unnecessary stress on the environment. We all want to reduce the impact of this. Leaky windows are the main reason for high energy costs. They not only let heat escape from your home and into the outside, but they also cause drafts that require the use of additional energy to heat your home. Installing double glazing using energy efficient windows will help to reduce energy costs and save you money year after year.

5. Faulty Windows

If you have a double glazed window that has become foggy, misty or hazy, this is an early sign that the seal has failed. It's also a sign that the glass has lost its insulation value and could lead to draughts and condensation. In addition, the gap around the edges of your windows can allow water to enter and damage your wall or plaster. This can also be a serious fire risk.

If the glass in your double glazing has become misty, it's important to repair it as soon as you can as it's a safety concern. It could also cost you more in energy bills due to the loss of insulation.

The cause of misty windows is moisture in the air between the two panes of your IGU (insulated glass unit). The gas contained within the glass - usually argon or krypton - helps with insulation, and when the seal fails, this gas escapes, causing the window replacement near me to fog up.

Failure of the seal in the early stages is a clear sign of a defective product so make sure to verify your warranty for coverage. Some manufacturers offer a prorated guarantee, based on the age of the window. This may be something to consider.
