Secondary glazing for Barnet homes
Around Barnet you will mostly find Georgian and Victorian houses, Edwardian villas and 1930s semis. On listed buildings, secondary glazing is often the preferred way to improve comfort, but check with the conservation officer as listed building consent may still be needed.
Behind Victorian sash windows, vertical sliding secondary glazing aligned with the meeting rail keeps the view uninterrupted and lets both windows open for ventilation. In 1930s bays, secondary glazing can follow each facet of the bay or span across it, so we measure carefully around radiators, sills and curtain tracks.
Parts of the High Street and Wood Street are conservation areas, so changes need care. We are about 7.5 miles from our Edmonton factory, and our team handles the whole job from survey to fitting.
Secondary glazing is a discreet second window fitted on the inside of your existing windows, leaving the originals untouched. It suits listed buildings, conservation areas, flats where external windows cannot be changed, and anyone wanting to cut noise and draughts without replacing period windows.
- Keeps original windows in place
- Suitable where replacement is restricted
- Panels open or lift out for cleaning
Questions from Barnet
Do I need planning permission for secondary glazing in Barnet?
Barnet has several conservation areas, including Wood Street and Monken Hadley, so we check with Barnet Council whether window or door changes need approval before quoting. Secondary glazing is fitted internally, so it does not usually need planning permission or Building Regulations approval, but listed buildings may need listed building consent first.
How soon can you fit secondary glazing in Barnet?
Lead times vary by product and workload — confirmed with your quote. Being about 7.5 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Can I still open my windows with secondary glazing fitted?
Yes. Secondary glazing can be made as sliding, hinged or lift-out panels, so you can open both the secondary unit and the original window for ventilation and cleaning. Fixed panels are also possible for windows you never need to open.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 7.5 miles from Barnet. We can also bring samples to your home in Barnet at the free survey.
