The workshop
London Sash Windows & Doors is a North London joinery company: we survey, advise, make and fit from our own workshop. We specialise in sliding sashes and heritage joinery.
We are FENSA registered, a Which? Trusted Trader, and we build in Britain. These credentials stand for accountable craft from the same team that measured your openings.
Clients come to us from Hornsey to Stratford, Belgravia to Dulwich, for work that respects the building and still makes the rooms better to live in.
