How much should I budget for security secondary glazing in Witham?
Budget £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Witham, supplied and fitted. Larger panes, thicker makeups and difficult access cost more; the price is fixed in writing after the survey.
Security secondary glazing is a separate slim window fitted on the room side of an existing window, glazed with laminated glass so it forms a second barrier. It leaves the original window untouched outside, which makes it a common choice for listed buildings, conservation areas and period sash windows.

- Suits sash, casement and arched openings
- Colour-matched frames to suit the room
- Low-E glass for better insulation
- Fixed within the reveal, leaving the original window untouched

What to think about first
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Consents and safety: 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.
Windows needed for escape
Approved Document B expects many habitable rooms in houses, particularly upstairs, to have an escape window with a clear opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. Changing the glass does not alter that, but locks, secondary glazing and film must not stop the window opening. Laminated glass is hard to break through, so escape always relies on the window opening.

Security secondary glazing in Witham: questions
Do you cover Maldon as well as Witham?
Yes. As well as Witham, we can arrange surveys in nearby Maldon, Braintree and Chelmsford. Dates depend on installer availability.
Is secondary glazing safe for escape windows?
It can be, as long as it opens quickly from inside without a key. We design catches and handles for that.
Will secondary glazing cause condensation?
A well-fitted unit usually reduces condensation on the inner pane. Some ventilation of the gap may be needed, which we discuss at the survey.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
