When a double glazed window goes misty, it means the seal around the edge of the unit has broken down and let moisture in between the two panes. Once it's there, no amount of cleaning will shift it - and the window has lost a lot of its insulation value too.
The good news: you don't need a brand new window. We simply remove the failed sealed unit and replace the glass itself, leaving your existing frame in place. It's quicker, much cheaper than a full replacement, and you'd never know it had been done.
We've been replacing misted double glazed units across Wilmslow, Alderley Edge, Knutsford and the wider Cheshire area for over 20 years. Most jobs are a single visit: we measure on the first call, manufacture the new unit, then return to fit it.

Frequently asked
Why do double glazed windows go misty?+
Modern sealed units have a desiccant strip around the edge that absorbs any tiny amounts of moisture. Over time - usually 10–20 years - the rubber seal degrades and lets water vapour in faster than the desiccant can cope. Once that happens, condensation appears between the panes.
Do I need a whole new window or just the glass?+
Almost always just the glass. The frame, hinges, locks and handles are normally fine. Replacing only the sealed unit can be 60–80% cheaper than a full replacement window.
How much does it cost to fix a misty window?+
It depends on the size and the type of glass, but standard misted units are surprisingly affordable. We'll give you a fixed price quote up front with no hidden extras.
How long does the repair take?+
Once the new unit is made, fitting takes around 20–40 minutes per window. We can usually do a full house of misted units in a single morning.
