Security secondary glazing in Berkshire

What should security secondary glazing cost in Berkshire?

Guide prices for security secondary glazing in Berkshire 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.

Frame colour and sightlines

Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.

Listed building consent

Internal secondary glazing is usually seen as reversible, but consent can still be needed. Check with the conservation officer first.

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.

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 Berkshire: questions

Which towns in Berkshire do you cover?

We can arrange work anywhere in Berkshire, including Reading, Slough, Bracknell, Maidenhead and Wokingham, and in other towns across the area.

Does secondary glazing reduce noise?

Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.

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.
