What Is Misted Double Glazing?

Misted or “blown” double glazing happens when the seal around your glass unit fails and then allows moisture to enter the space between the panes. This trapped condensation causes the cloudy or foggy effect that many homeowners notice. Once this happens, the insulating gas has escaped, meaning your windows are no longer performing as they should.

Misted Glass Replacement FAQ's

Yes. In most cases, we only need to replace the sealed glass unit, not the entire frame. This is quicker, far more affordable, and restores the energy efficiency and clarity of your windows without unnecessary replacement costs.

Common signs include condensation between the panes, cloudy or foggy glass, water droplets inside the unit, and cold draughts around the window. If you notice any of these, the sealed unit has likely failed and needs replacing.

Most glass unit replacements take around 20–40 minutes per window, depending on size and accessibility. We’ll always aim to complete the work quickly and with minimal disruption, while ensuring a professional finish.

Over time, temperature changes cause the gas between your glazing panes to expand and contract. This repeated movement can weaken the seals, particularly in older units. When the seal fails, moisture enters, and this then leads to misting, internal condensation, and reduced thermal efficiency.

Common causes include:

    • Ageing or deteriorated window seals

    • Exposure to harsh weather

    • Poor installation

    • General wear and tear

While some companies offer temporary “repair” solutions, these rarely last. To fully restore the performance of your windows, we recommend replacing the glass unit only, not the whole window. This is usually quick, cost-effective, and ensures your double glazing performs as intended.

How Much Does Misted Glass Replacement Cost?​
