If you’ve spotted misted or foggy windows at home, you may be dealing with blown double glazing. When the seal between panes of glass fails, moisture builds up inside—impacting not only your view but also your comfort and energy efficiency.
But what should you do about it? Is it better to repair the affected window or go for a full replacement?
In this guide, we’ll help you decide what’s right for your home. Plus, we’ll walk you through 5 key signs it’s time to act and how we can help with window repairs in Brighton and beyond.
What Is Blown Double Glazing?
Blown double glazing happens when the airtight seal in a double-glazed unit breaks. This allows moisture and air to seep between the panes, creating a foggy or misty appearance that won’t go away, even after cleaning. Over time, this can lead to:
- Compromised window security
- Reduced insulation
- Condensation and mould
- Higher energy bills
Repair or Replace? How to Make the Right Call
At Sussex Glazing Solutions, we always aim to repair where possible, especially when the window frame and hardware are in good condition.
✅ Choose Repair If:
- The misting is isolated to one or two panes
- The frames are structurally sound
- You want a cost-effective fix without replacing the entire unit
See our window repairs page for more info.
🔁 Choose Replacement If:
- Multiple panes are blown or damaged
- Your windows are over 15–20 years old
- The frames or locks are failing too
Repairing the panes, saving you money on the frames!

5 Signs It’s Time to Act on Blown Double Glazing
Here’s what to watch for:
1. Condensation Between the Glass
If mist or water droplets appear between the panes and won’t wipe away, your unit is blown.
2. Cold Drafts Around Windows
This could be a sign of seal failure or damage to your window hinges or locks.
👉 We also offer expert window hinge repair services.
3. Rising Energy Bills
Heat escapes easily through failed glazing, forcing your heating to work harder.
4. Stiff or Faulty Locks
If your window won’t close securely, it’s not just frustrating—it’s a security risk.

5. Visible Cracks or Gaps in the Frame
