Security secondary glazing in Hertford

How much should I budget for security secondary glazing in Hertford?

Our guide range for security secondary glazing in Hertford is £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window, including fitting. The survey is free for new installations and your fixed price follows in writing.

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.

Laminated glass in slim aluminium frames
Vertical sliding, horizontal sliding, hinged and lift-out styles

Low-E glass for better insulation

What to think about first

How it opens

Match the opening style to the original window so both can be opened, cleaned and used for ventilation.

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

Planning permission

Changing the glass in an existing window or shopfront does not usually need planning permission, because the building looks much the same afterwards. A new or altered shopfront, or security features added to the outside of a building, may need planning permission from the council. Bollards or barriers on the pavement need the highway authority's consent, which is normally the council.

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 Hertford: questions

Do you cover Hoddesdon as well as Hertford?

Yes. As well as Hertford, we can arrange surveys in nearby Hoddesdon, Welwyn Garden City and Hatfield. 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.

Can I still open my sash windows?

Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.

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.
