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 to think about first
Replace the frame instead
If frames are rotten, warped or very old, new windows may be better value. We will tell you honestly.
Energy specification
New low-E and argon units are usually warmer than the ones they replace.

Security rules for new homes
Approved Document Q has applied to new homes in England since 1 October 2015. Easily accessible doors and windows, meaning any part within 2 m vertically of the ground or another accessible surface, should meet PAS 24 or an equivalent, and glazing in doors and in windows within 400 mm of a door should be laminated to at least BS EN 356 P1A. It does not apply when you change the glass in an existing home, although it is a sensible benchmark.
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 Welwyn Garden City: questions
Can you survey in Welwyn Garden City and nearby towns?
Yes. Surveys in Welwyn Garden City, Hatfield and Hertford are booked around 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.
Can misted glass be repaired instead of replaced?
Some services drill and dry units, but the seal stays broken and insulation is not restored. A new unit is the reliable fix.
Do I need a new window frame?
No, if the frame is sound. We replace only the sealed unit.
