Secondary glazing for Theydon Bois homes
Homes in Theydon Bois are mostly Victorian cottages, interwar detached houses and post-war homes. 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. Older cottages with small leaded or timber windows can keep their character with discreet secondary panels, hinged or removable so the originals stay accessible for maintenance.
Planning rules near the green and forest can be stricter than in suburban streets, so we check before quoting. We are about 7.5 miles from our Edmonton factory and handle surveys, manufacturing and fitting ourselves.
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
- Reduces draughts and outside noise
- Suitable where replacement is restricted
Questions from Theydon Bois
Do I need planning permission for secondary glazing in Theydon Bois?
Some parts of Theydon Bois fall within conservation areas and the Green Belt, so we check with Epping Forest District Council 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 Theydon Bois?
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 Theydon Bois. We can also bring samples to your home in Theydon Bois at the free survey.
