What should security secondary glazing cost in Leatherhead?

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.
What you can specify
- Locks and catches that open from inside without a key
- Suits sash, casement and arched openings
- Laminated glass in slim aluminium frames
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Noise and draught reduction
- Colour-matched frames to suit the room

Before the glass is ordered
Escape and ventilation
On windows used for escape, the secondary glazing must open quickly from inside without a key or tool.
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
Glazing rules in England
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.
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 secondary glazing in Leatherhead: questions
Do you cover Epsom as well as Leatherhead?
Yes. As well as Leatherhead, we can arrange surveys in nearby Epsom, Ewell and Esher. Dates depend on installer availability.
Do I need permission for secondary glazing in a listed building?
It depends on the building and the council. Internal secondary glazing usually has less impact than replacement windows, but listed building consent may still be needed. Ask the conservation officer before ordering.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
