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
- Obscure and decorative glass matched where possible
- Laminated inner pane for security
- Old units removed and disposed of
- Existing frames, handles and locks kept
- Low-E glass, argon fill and warm-edge spacers
- Security tape on externally beaded frames
Fitting in Harrow and nearby
We arrange surveys and fitting in Harrow and across the HA1 postcode district, as well as in nearby Wembley (2 miles) and Northolt (3 miles). Dates depend on installer availability.
Greater London has every kind of glazing, from Georgian sashes and Victorian bays in conservation areas to high-street shopfronts, office curtain walling and new-build flats.
Typical settings for misted unit replacement with laminated glass:
- Rented homes with a few failed units
- Units with blown seals in sunny elevations
- Homes where frames are sound but glass is tired
- Door glass that has gone cloudy
Getting the right glass for your building
Energy specification
New low-E and argon units are usually warmer than the ones they replace.
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
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.
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.

Misted unit replacement with laminated glass in Harrow: questions
Do you cover Wembley as well as Harrow?
Yes. As well as Harrow, we can arrange surveys in nearby Wembley, Northolt and Greenford. 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.
Do I need a new window frame?
No, if the frame is sound. We replace only the sealed unit.
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.
