Premium Window Installation in Kensington, London

Kensington falls within the Royal Borough of Kensington and Chelsea, which has some of London's strictest conservation controls. Most of Kensington is covered by conservation areas requiring timber sash windows with authentic profiles. The council publishes detailed design guidance for each conservation area.

Kensington's grand stucco-fronted terraces require tall, slender timber sash windows, typically one-over-one or two-over-two configurations. Glazing bars must be slim and proportionate. We specialise in heritage sash windows using engineered hardwood with traditional putty-line glazing for authentic appearance.

Secondary glazing is often the preferred solution for Kensington's numerous listed buildings. It provides excellent thermal and acoustic performance without altering the external appearance. Our bespoke secondary glazing systems are virtually invisible from inside and can reduce noise by up to 80 percent.
