Double Glazing & Misted Unit Replacement Across London
If misting appears between the two panes of glass, the seal has usually failed. (Condensation on the inside or outside surface alone does not mean the unit has failed.) In most cases the frame is perfectly good and only the sealed unit needs replacing - which is far cheaper than a whole new window.
Keep your existing frames
We swap the glass only where the frame is sound, which keeps the cost down.
Specified for the job
We talk through glass options - thermal, acoustic, obscure, toughened or laminated - and specify what suits your window and how the room is used.
Made to measure
Every unit is measured on site and manufactured to your exact sizes.
Clear written quote
You get an itemised price before anything is ordered. No hidden extras.

Common questions
Why has my double glazing gone foggy?
The seal around the unit has failed and moisture is trapped between the panes. Once that happens the unit cannot be dried out - it needs replacing.
Do I need a whole new window?
Usually not. If the frame and hinges are sound we only replace the sealed unit.
How long does it take?
Measuring takes minutes. Units are then made to order, and fitting a typical unit takes under an hour once the glass arrives.
Can you match obscure or patterned glass?
Yes - bring us a photo and we will match the pattern from the standard UK range where it is still produced.
