Sash windows for New Barnet homes
Homes in New Barnet are mostly Victorian and Edwardian terraces, 1930s semis and modern 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.
The East Coast Main Line runs straight through New Barnet, and trains pass often, so homes that back onto the railway gain a lot from acoustic double glazing. We are about 6.3 miles from Edmonton, so our own team can survey, make and fit, with no subcontractors.
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.
- Traditional look with modern weather sealing
- Smooth vertical sliding operation
- Fewer draughts and rattles than worn originals
Questions from New Barnet
Do I need planning permission for sash windows in New Barnet?
Some streets in New Barnet fall within conservation areas, so we check with Barnet Council before quoting and confirm any freeholder requirements for flats. 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 New Barnet?
Lead times vary by product and workload — confirmed with your quote. Being about 6.3 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Should I repair or replace my old sash windows?
If the timber is mostly sound, repair and draught-proofing can extend the life of original sashes, and may be required on listed buildings. Where frames are rotten, sashes are badly warped or you want much better insulation than single glazing gives, replacement is usually more practical. We'll give you an honest view after inspecting them.
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 6.3 miles from New Barnet. We can also bring samples to your home in New Barnet at the free survey.
