What is the price of security secondary glazing in Hitchin?
As a guide, allow £594 to £1,794 including VAT (£495 to £1,495 plus VAT) per window for security secondary glazing in Hitchin, 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.
Glass and fitting options
- Colour-matched frames to suit the room
- Vertical sliding, horizontal sliding, hinged and lift-out styles
- Noise and draught reduction
- Locks and catches that open from inside without a key
- Suits sash, casement and arched openings
- Fixed within the reveal, leaving the original window untouched
Fitting in Hitchin and nearby
From the SG4 district we also cover Letchworth Garden City (3 miles) and Stevenage (5 miles). Survey dates depend on installer availability.

This glazing suits:
- Ground-floor flats in converted townhouses
- Offices in historic buildings
- Listed homes and buildings in conservation areas
- Homes on busy roads wanting noise reduction
Questions we will ask at the survey
How it opens
Match the opening style to the original window so both can be opened, cleaned and used for ventilation.
Frame colour and sightlines
Slim frames that line up with the existing meeting rails make the secondary glazing almost invisible from outside.
Building regulations and safety in 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 Hitchin: questions
Can you survey in Hitchin and nearby towns?
Yes. Surveys in Hitchin, Letchworth Garden City and Stevenage are booked around 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.
Does secondary glazing reduce noise?
Yes, often noticeably, because of the air gap between the two panes. Laminated glass helps further.
Can I still open my sash windows?
Yes. Secondary glazing slides, hinges or lifts out so the original window can be opened and cleaned.
