Security secondary glazing in Andover: what will it cost?

Guide prices for security secondary glazing in Andover are £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for supply and fitting. We confirm a fixed price in writing after a free survey, before any glass is ordered.

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.

Getting the right glass for your building

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.

What the rules say in England

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.

Listed buildings and conservation areas

In England, listed building consent from the council may be needed to replace historic glass such as crown or cylinder glass, or to alter glazing bars, sashes and frames. Historic England publishes guidance on traditional windows. Secondary glazing and window film are often easier to agree because they can be removed later, but the council's conservation officer makes the decision.

Security secondary glazing in Andover: questions

Do you cover Winchester as well as Andover?

Yes. As well as Andover, we can arrange surveys in nearby Winchester, Newbury and Salisbury. 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.

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.
