Sash windows for Hendon homes
The housing in Hendon is largely interwar semis, Victorian terraces near Church End and purpose-built flats. 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.
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. In mansion blocks, sash replacement is often controlled by the freeholder or managing agent, so get written approval of the glazing pattern and material before ordering.
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
- Matched to original proportions and glazing bars
- Smooth vertical sliding operation
Questions from Hendon
Do I need planning permission for sash windows in Hendon?
Hendon's Church End is a conservation area, so we check designs with Barnet Council before quoting there; most other replacements need no permission. 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 Hendon?
Lead times vary by product and workload — confirmed with your quote.
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), not far from Hendon. We can also bring samples to your home in Hendon at the free survey.
