Failed Misted Double Glazing Units


Foggy, misted windows? In most cases we replace just the failed sealed unit, not the whole window, so you get a clear view back for less.

"Cheaper than the national franchises for failed units, and the money stays local. Win win."

Neil Busby, Google (5★)

When a double glazed unit fails, the seal breaks and moisture gets in between the panes. You get that foggy, misted look you cannot clean off, and the window stops doing its job. The good news is that you usually do not need a whole new window.

The Problem


Call a national installer about a misted window and you are often quoted for a whole new frame you do not need. That is a lot of money and disruption for a problem that is usually just the glass.


We replace the sealed glass unit inside your existing frame. Same window, clear glass again, at a fraction of the cost of a replacement window.

Common Questions

  • Can a misted double glazed window be repaired?

    In most cases we simply replace the failed sealed unit inside your existing frame, rather than the whole window.

  • Do I need a whole new window?

    Usually not. If the frame is sound and only the glass has misted, replacing the unit is far cheaper.

  • How long does it take?

    Each unit is made to measure, so there is a short lead time. We will give you a realistic date when we quote. It is not a same-day job.

  • Is it much cheaper than a new window?

    Yes, replacing the sealed unit is a fraction of the cost of a whole new window.
