Replace foggy, condensation-filled double glazing without replacing the whole window
Misted or 'blown' double glazing happens when the seal between the two panes fails, letting moisture into the sealed unit cavity. The trapped moisture condenses and looks like permanent fogging. The good news: in most cases you don't need to replace the whole window — just the failed sealed unit inside the existing frame. S&K Glazing replaces misted units across the UK, typically same week, often with no scaffolding required.
A selection of recent misted unit replacement installations across the UK.
We visit, measure the failed unit, identify the glass thickness and any obscure pattern, and quote a fixed price.
Standard clear units: 3-5 working days. Obscure or patterned glass: 5-10 days.
Most misted units are swapped in 20-30 minutes per window. A full house of 8-10 windows is typically completed in a single morning.
All replacement units come with a 10-year sealed-unit warranty.
We install misted unit replacement from our Birmingham facility to every corner of the UK. Find your area below.
