What to think about first
Unit thickness
We match the overall thickness to your frame so the beads fit properly.
Replace the frame instead
If frames are rotten, warped or very old, new windows may be better value. We will tell you honestly.
Consents and safety: Wales
Replacing glass in an existing frame
Welsh Government guidance says building regulations have applied to replacement glazing since 1 April 2002, which covers replacing windows and doors. Swapping only the glass or a sealed unit in an existing frame is generally treated as a repair. New glass in a critical location should still be safety glass, and the council's building control team can confirm anything unclear.
Security rules for new homes
Wales introduced its own Approved Document Q for new homes, in force from 1 November 2018, and it applies to newly erected dwellings only. It follows a similar approach to England's, with PAS 24 referenced for easily accessible doors and windows and laminated glass to BS EN 356 P1A in doors and nearby windows. It does not apply to changing the glass in an existing home.

Misted unit replacement with laminated glass in Caerphilly: questions
Do you cover Risca as well as Caerphilly?
Yes. As well as Caerphilly, we can arrange surveys in nearby Risca, Pontypridd and Cardiff. Dates depend on installer availability.
Why is there condensation between my window panes?
The seal around the unit has failed, letting damp air into the gap. The only lasting fix is a new unit.
Does replacing a unit need building regulations approval?
Replacing glass or a sealed unit in an existing frame is generally treated as a repair rather than new building work, across the UK. Replacing the whole window is different and is controlled.
Do I need a new window frame?
No, if the frame is sound. We replace only the sealed unit.
