Looking for misted unit replacement in Barnet? S&K Glazing has been installing across Greater London for over a decade. 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.
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.
Barnet borough's mix of suburban 1930s housing, period properties in Hampstead Garden Suburb, and commercial premises along the A1 corridor keeps us busy across EN, N and NW postcodes. Premium aluminium bifolds, sash window replacement and double-glazing upgrades are our most-requested local services.
For window-replacement work in Barnet, the property mix across London ranges from period stock through to modern new-build, so we specify the thermal solution per property — A++ rated double-glazed sealed units for standard upgrades (U-value 1.4 W/m²K), A-rated solar-control glazing for south-facing elevations, and triple-glazed argon-filled builds achieving 0.8 W/m²K for owners targeting near-Passivhaus performance. Most commonly we're working in A1 postcodes.
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.
