Working in Barnet

Barnet borough's mix of suburban 1930s housing, period properties in Hampstead Garden Suburb, and commercial premises along the A1 corridor keeps us busy across EN, N and NW postcodes. Premium aluminium bifolds, sash window replacement and double-glazing upgrades are our most-requested local services.

For window-replacement work in Barnet, the property mix across London ranges from period stock through to modern new-build, so we specify the thermal solution per property — A++ rated double-glazed sealed units for standard upgrades (U-value 1.4 W/m²K), A-rated solar-control glazing for south-facing elevations, and triple-glazed argon-filled builds achieving 0.8 W/m²K for owners targeting near-Passivhaus performance. Most commonly we're working in A1 postcodes.

Yes — any RAL colour, plus dual-colour options (different inside and outside). Anthracite grey 7016, jet black 9005, and white 9010 are our most popular.
