Signs Your Double Glazing Has Failed

1. Fogging or misting between panes
2. Visible moisture droplets inside the unit
3. Draughts around frames 
4. Discoloured spacer bars 
5. Increased heating bills 
6. Failed seals allow moisture into the cavity, reducing insulation performance.

Why Repair or Replace Failed Units?
Restore Thermal Efficiency - Failed units lose insulating gas and no longer perform effectively.
 Prevent Frame Damage - Persistent moisture can affect seals, beads and surrounding materials.
Improve Appearance - Clear glazing enhances kerb appeal and natural light.
Cost-Effective Solutions -  Often, only the sealed glass unit needs replacing — not the entire frame.

Why Double Glazing
Comfort • Efficiency • Protection
Double glazing is one of the most effective upgrades you can make to improve comfort, energy efficiency and property value. If your units have failed, timely repair or replacement restores performance and prevents further issues.

The Benefits of Double Glazing

Lower Energy Bills
Two panes of glass with an insulated cavity reduce heat loss, helping your home stay warmer in winter and cooler in summer. 

Reduced Condensation
Properly sealed units minimise internal condensation and help prevent mould growth.

Improved Sound Insulation Double glazing reduces external noise — ideal for properties near roads or busy areas.

Enhanced Security
Modern units are tougher and often incorporate multi-point locking systems.

Increased Property Value
Energy-efficient windows are attractive to buyers and improve EPC ratings.
