Local advice

Double glazing for Finchley homes

Homes in Finchley are mostly Edwardian terraces, 1930s semis and post-war flats. Many Victorian terraces still have single-glazed sashes, and moving to double glazing is often the biggest single comfort upgrade, whether through new windows or secondary glazing.

Original 1930s leaded lights can be replicated within double glazed units, so you keep the decorative pattern while gaining modern insulation and quieter rooms. In homes built from the 1980s onwards, misted or blown double glazed units are common, and replacing just the glass often restores performance without new frames.

Because our factory is a short drive away in Edmonton, surveys, fitting days and any aftercare visits are easy to arrange.

Double glazing uses two panes of glass with a sealed, insulating gap between them, cutting heat loss, draughts and condensation compared with single glazing. We fit it in new windows and doors or as replacement sealed units, suiting almost every home, from older properties still single glazed to houses with failed units.

Questions from Finchley

Do I need planning permission for double glazing in Finchley?

Parts of Finchley, including Finchley Church End, are conservation areas, so we check Barnet Council's guidance before quoting for window style changes. Replacing only the sealed glass units in existing frames does not normally need Building Regulations notification, while full window replacements are covered by our FENSA registration, though listed buildings may need consent.

How soon can you fit double glazing in Finchley?

Lead times vary by product and workload — confirmed with your quote. Being about 6.6 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.

Is double glazing still worth it compared with triple glazing?

For most homes in Finchley, modern double glazing, typically with low-emissivity coated glass, performs very well. Triple glazing improves insulation further but adds weight and cost. The right choice depends on your property, frames and priorities, which we can talk through when we survey.

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 6.6 miles from Finchley. We can also bring samples to your home in Finchley at the free survey.
