How to Fix Steamed Up Double Glazing in Preston
If you’ve noticed condensation or cloudiness trapped between the panes of your windows, you are likely dealing with steamed up double glazing. This is a common issue for properties across Preston and Lancashire. In this guide, we explain what causes misted windows, why DIY fixes rarely work, and the most effective professional solution.
What is Steamed Up Double Glazing?
Double glazing consists of two panes of glass sealed around the edges to form an insulated unit. When that perimeter seal fails, moisture enters the cavity between the panes and becomes trapped. This results in a foggy or misted appearance that cannot be wiped away.
This affects:
- Visibility through the window
- Thermal insulation performance
- Energy efficiency in your home
What Causes Double Glazing to Steam Up?
Age and Wear
Over time, exposure to British weather conditions can cause seals to deteriorate.
Seal Breakdown
When the edge seal degrades, moisture penetrates the unit and condensation forms internally.
Frame Movement
Structural movement can stress glazing units and weaken seals.
Poor Installation
Incorrect fitting or low-quality units are more likely to fail prematurely.
Can You Fix Steamed Up Double Glazing Yourself?
Some online methods suggest drilling holes in the glass or using moisture absorbers. While these may temporarily reduce visible condensation, they do not restore insulation or repair the failed seal.
DIY alterations can weaken the glass and often lead to full replacement being required.
The Professional Solution: Sealed Unit Replacement
The most effective and long-lasting solution is replacing the failed sealed unit while keeping your existing window frame.
This restores:
- Clear visibility
- Thermal efficiency
- Sound insulation
- The appearance of your windows
How the Process Works

- Precise measurements are taken.
- A new double glazed unit is manufactured to match.
- The failed unit is removed safely.
- The new sealed unit is installed securely.
