Sash windows in NW3

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.

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.

Replacement windows here are reviewed closely, so we focus on slim, period-style designs. Finchley Road and Haverstock Hill carry heavy traffic, and flats facing them benefit from acoustic laminated glass. In mansion blocks we check lease terms and any agreed window specification first. NW3 is about 6.6 miles from our Edmonton factory.

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.

• Matched to original proportions and glazing bars
• Smooth vertical sliding operation
