Local advice

Double glazing for N1 homes

In conservation areas, slim double glazed units can sometimes be fitted into traditional-style frames, but check with the council first, as listed buildings usually need consent.

Many Victorian terraces still have single-glazed sashes, and moving to double glazing is often the biggest single comfort upgrade, whether through new windows or secondary glazing. If your flat's frames are in good order, replacing only failed or misted double glazed units may avoid the need for freeholder approval for new windows.

Upper Street, Essex Road, City Road and the Regent's Canal shape the district. We are about 4.9 miles from N1 and can advise on sash-style and heritage-appropriate designs.

Double glazing uses two panes of glass with a sealed, insulating gap between them, cutting heat loss, draughts and condensation compared with single glazing. We fit it in new windows and doors or as replacement sealed units, suiting almost every home, from older properties still single glazed to houses with failed units.

  • Warmer rooms and lower heat loss
  • Less condensation on the glass
  • Quieter rooms than single glazing

Questions from N1

Do I need planning permission for double glazing in N1?

Replacing only the sealed glass units in existing frames does not normally need Building Regulations notification, while full window replacements are covered by our FENSA registration, though listed buildings may need consent.

How soon can you fit double glazing in N1?

Lead times vary by product and workload — confirmed with your quote. Being about 4.9 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.

Why is there condensation between my double glazed panes?

Condensation inside the unit means the seal has failed and moist air has got into the gap, so the unit has lost much of its insulating value. The frame itself is often fine, in which case we can measure and replace just the sealed unit rather than the whole window.

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 4.9 miles from N1. We can also bring samples to your home in N1 at the free survey.
