Misted unit replacement with laminated glass in Potters Bar: what will it cost?
Our guide range for misted unit replacement with laminated glass in Potters Bar is £150 to £474 including VAT (£125 to £395 plus VAT) per unit, including fitting. The survey is free for new installations and your fixed price follows in writing.
Misted unit replacement means swapping a double-glazed unit whose seal has failed, so moisture has got between the panes, for a new sealed unit. Doing it with a laminated pane turns a routine repair into a security upgrade for little extra cost.
What you can specify
- Laminated inner pane for security
- Existing frames, handles and locks kept
- Obscure and decorative glass matched where possible
- New sealed units made to measure
- Toughened panes where safety glass is required
- Low-E glass, argon fill and warm-edge spacers

Typical settings for misted unit replacement with laminated glass:
- Units with blown seals in sunny elevations

- Windows with condensation between the panes

Getting the right glass for your building
Unit thickness
We match the overall thickness to your frame so the beads fit properly.
Laminated or standard
A laminated inner pane adds security for a small extra cost while the unit is being made.
What the rules say in England
Safety glass in critical locations
In England, section 5 of Approved Document K treats glazing in doors and in side panels within 300 mm of a door edge, from floor level up to 1,500 mm, and any other glazing below 800 mm, as a critical location. Glass there should break safely, be robust, or be guarded. Laminated or toughened glass meeting BS EN 12600 class 3 is the usual answer, rising to class 2 for door and side-panel panes wider than 900 mm.
Replacing glass in an existing frame
Replacing only the glass or sealed unit in an existing frame is generally treated as a repair in England rather than notifiable building work. Replacing a whole window or door is notifiable and is normally certified through a competent person scheme or approved by building control. Either way, new glass in a critical location should still be safety glass.

Misted unit replacement with laminated glass in Potters Bar: questions
Do you cover Barnet as well as Potters Bar?
Yes. As well as Potters Bar, we can arrange surveys in nearby Barnet, Enfield and Borehamwood. Dates depend on installer availability.
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.
Will the new unit match the others?
We match the size, spacer colour and glass as closely as we can, including common obscure patterns.
