Sash windows for NW7 homes
In conservation areas and on listed buildings, councils may insist on timber sashes or repair rather than replacement, so check with the planning team before choosing materials.
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 M1, A1 and A41 all pass through NW7, bringing noise to nearby streets. Larger homes here often want wide-span patio doors. We are about 8.2 miles from Mill Hill. Edgware, to the west, has the HA8 postcode.
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 NW7
Do I need planning permission for sash windows in NW7?
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 NW7?
Lead times vary by product and workload — confirmed with your quote. Being about 8.2 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 8.2 miles from NW7. We can also bring samples to your home in NW7 at the free survey.
