Can double glazing be repaired?

In many cases, yes. From blown units to stiff hinges, a lot can be fixed without a full replacement.

Can fogged double pane windows be repaired?

Yes. The fogging is due to a broken seal. The glass unit can usually be swapped out without replacing the whole frame.

Can condensation between double glazing be fixed?

Yes. This is a classic sign of a blown double glazing unit. It usually means replacing the glass, not the whole window.

Can I replace just one pane in a double glazed window?

Yes. If only one pane is blown or cracked, many glaziers can replace just that glass unit without touching the frame. It’s a cost-effective fix that restores performance without the faff of a full replacement.

How do I know if my double glazing is blown?

Look for misting or condensation trapped between the panes. It’s a sign the seal has failed and the insulating gas has escaped. __Other clues:__ - The window feels colder than it should - You’re getting more noise from outside

Is it worth repairing double glazing?

Often, yes. If the frame is sound, replacing the glass unit is usually cheaper than a full window replacement.

How much does window replacement cost?

The exact cost will depend on several factors, including the size, style, material, and glazing type. As a rough guide, here are some average costs for the supply and installation of a new window in the UK: - Casement windows – **£500** - Sash windows – **£1,000** - Sliding windows – **£700** - Tilt and turn windows – **£700** - Bay windows – **£2,500** - Bow windows – **£3,000** It’s worth noting that these are estimated average costs, and actual prices may vary. **Factors affecting the cost of window replacement** To get a more accurate price for replacing your window(s), you’ll want to consider the following factors: - Size of the window(s) – Larger windows generally cost more - Type of glazing – Double or triple glazing is more expensive than single glazing - Window style – Bay windows and other complex styles cost more than standard windows - Quality and type of materials – Higher-quality windows often come with a higher price tag and different materials, like uPVC and timber, have varying costs - Number of windows – The more windows you need, the higher the overall cost - Location – Labour costs often vary depending on where you live, e.g. London and the South East are typically more expensive than other parts of the country Learn more about window replacement pricing in our [guide to double glazing costs](https://www.checkatrade.com/blog/cost-guides/double-glazing-cost/).
