Double-glazed windows are a popular choice in the UK as they offer several benefits, such as improved energy efficiency, noise reduction, and increased home security. However, like all windows, double-glazed windows can develop issues that require repair. If you’re wondering how much it costs to fix a double-glazed window in the UK, read on.

Broken or damaged glass

Broken or damaged glass is a common issue with double-glazed windows. It can be caused by accidental breakage, extreme weather conditions, or even attempted break-ins. The cost of replacing a double-glazed window pane can range from £50 to £500, depending on the size and type of the window. If the window is an unusual shape or has decorative features, the cost may be higher.

Failed seals

Failed seals are a common issue with double-glazed windows and can lead to condensation forming between the panes. This can cause the window to look foggy or misty and can also reduce its energy efficiency. The cost of repairing a failed seal can range from £50 to £250 per window. If left untreated, failed seals can lead to further damage to the window, such as mold growth or even the need for a full window replacement.

Drafty windows

Drafty windows can be caused by several factors, such as a faulty seal, a gap in the frame, or even poor installation. Not only can drafts make your home feel less comfortable, but they can also increase your energy bills. The cost of repairing a drafty window can range from £50 to £200 per window. Fixing the issue promptly can help prevent further damage to the window and improve your home’s energy efficiency.

Broken handles or hinges

Handles and hinges are essential components of double-glazed windows and are used to open and close the window. Over time, they can become worn or damaged, making it difficult to operate the window. The cost of replacing a handle or hinge can range from £50 to £150 per window. Fixing these issues promptly can help ensure the longevity of your windows and improve their functionality.

Locking mechanisms

The locking mechanism is an important security feature of double-glazed windows, and a faulty mechanism can compromise your home’s safety. If the locking mechanism is not working correctly, it may need to be repaired or replaced. The cost of repairing a locking mechanism can range from £50 to £200 per window. It’s important to address these issues promptly to ensure your home’s security is not compromised.


It’s important to note that the cost of fixing a double-glazed window in the UK can vary depending on several factors, including the location of the window, the type and severity of the issue, and the cost of materials and labor in your area.
