Secondary glazing for Highgate homes
Homes in Highgate are mostly Georgian houses, Victorian villas, terraces and mansion blocks. 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. For flats where the lease or freeholder prevents changing external windows, secondary glazing fitted inside is usually the simplest way to reduce traffic noise and heat loss.
We make sash windows to the original proportions and glazing bar patterns. Where the old frames must stay, secondary glazing fitted inside improves comfort without altering anything from the street. Houses on Archway Road face a lot of traffic, and acoustic glass helps there. Highgate is about 5.2 miles from our factory.
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 Highgate
Do I need planning permission for secondary glazing in Highgate?
Highgate is a conservation area split between Haringey and Camden councils, with many listed buildings, so we check your property's status and the right council's guidance 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 Highgate?
Lead times vary by product and workload — confirmed with your quote. Being about 5.2 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 5.2 miles from Highgate. We can also bring samples to your home in Highgate at the free survey.
