Sash windows for Finchley homes
Around Finchley you will mostly find Edwardian terraces, 1930s semis and post-war flats. Victorian and Edwardian terraces often have two-over-two or one-over-one sashes with horns, and matching that pattern exactly keeps the front elevation consistent with neighbouring houses.
Some 1920s houses have sash windows alongside bays, so note whether the bay sashes slide or are fixed before deciding how closely to match the original arrangement. Newer homes built in a traditional style sometimes have mock sashes, and genuine sliding sashes can replace them where you want a more authentic opening action.
Because our factory is a short drive away in Edmonton, surveys, fitting days and any aftercare visits are easy to arrange.
Sliding sash windows open vertically and give period homes their familiar look, with balanced sashes, horns and glazing bars. We make replacement sash windows to match original proportions, suiting owners of Victorian, Edwardian and Georgian properties who want better insulation and security without losing traditional character.
- Matched to original proportions and glazing bars
- Smooth vertical sliding operation
- Fewer draughts and rattles than worn originals
Questions from Finchley
Do I need planning permission for sash windows 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. Replacement sash windows on a house are usually permitted development if they look similar, with FENSA covering Building Regulations, but conservation areas with Article 4 directions, listed buildings and flats often need consent.
How soon can you fit sash windows 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.
Will replacement sash windows look the same as my originals?
We match the proportions, glazing bar layout and features such as horns as closely as possible. Modern sashes hold thicker double glazed units and weather seals, so sightlines can differ slightly from slim single-glazed originals, which is worth seeing in person before you decide.
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.
