Security secondary glazing in South Croydon

Security secondary glazing in South Croydon: what will it cost?

As a guide, allow £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in South Croydon, supplied and fitted. Size, glass makeup, access and frame condition move the price, which is confirmed in writing after the free 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.

Getting the right glass for your building

Listed building consent

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

Frame colour and sightlines

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

What the rules say in England

England

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.

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 South Croydon: questions

Do you cover Croydon as well as South Croydon?

Yes. As well as South Croydon, we can arrange surveys in nearby Croydon, Purley and Wallington. Dates depend on installer availability.

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.

Does secondary glazing reduce noise?

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

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.
