Sash windows for AL9 homes

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.

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.

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 AL9

Do I need planning permission for sash windows in AL9?

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 AL9?

Lead times vary by product and workload — confirmed with your quote. Being about 11 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.

Will the council allow replacement sash windows in AL9?

It depends on the property. Houses outside conservation areas usually have permitted development rights for similar-looking windows. In conservation areas with Article 4 directions, on listed buildings and for flats, you may need permission, and some councils require timber. Checking with the planning department before ordering avoids problems later.

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 11 miles from AL9. We can also bring samples to your home in AL9 at the free survey.
