Sash windows for N9 homes
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.
On larger period houses with many sashes, prioritise the most draughty or damaged windows first, and record the glazing bar layouts so later phases match exactly. 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.
Hertford Road, the A10 to the west and the West Anglia line all bring traffic and train noise. Many 1980s and 1990s double-glazed units in the district have now misted or lost their seals. We are only about 1.3 miles from N9, which keeps surveys and fitting quick.
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.

Questions from N9
Do I need planning permission for sash windows in N9?
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 N9?
Lead times vary by product and workload — confirmed with your quote. Being about 1.3 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 1.3 miles from N9. We can also bring samples to your home in N9 at the free survey.
