Double glazing in Swiss Cottage

The housing in Swiss Cottage is largely mansion blocks, Victorian houses converted to flats and post-war estates. 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. In homes built from the 1980s onwards, misted or blown double glazed units are common, and replacing just the glass often restores performance without new frames.

The Finchley Road (A41) is one of the busiest roads in North London, so acoustic glazing is often the first thing people ask about. We help agree designs with managing agents or freeholders and plan access and parking in advance, as shared buildings and controlled parking zones make careful planning essential.

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
