Replacement Units
A failed unit is not a failed window.
When a double glazed unit mists up, it is the seal that has gone — not the frame. Replacing the sealed glass unit restores the clarity, the insulation and the guarantee at a fraction of the cost and disruption of new windows.
The failed unit
Misting between the panes means the seal has gone — the glass is no longer insulating.
The swap
Templated, manufactured to size and glazed back into your existing frame.
What we replace and upgrade
- Misted or blown
- Failed perimeter seals, condensation and misting trapped between the panes.
- Cracked or broken
- Single panes or complete units, toughened or laminated to match what is already there.
- Any frame
- UPVC, aluminium and timber — measured or templated, so your frame stays exactly where it is.
- Upgraded glass
- Low-E energy, solar control, self-cleaning, acoustic or obscure — specified while the unit is being built.
- Conservatories & lanterns
- Including solar control glass, so a conservatory stops becoming unusable in the summer.
- Guarantee
- Five to ten years on the sealed unit, depending on the glass specified.
Send us a photograph of the window and a rough size and we will come back with a price the same day — most units are glazed in under an hour.
