Specialists in London sash windows
See our workThe Sash Window Man (London) brings together almost 30 years of hands-on experience in restoring and replacing timber box sash windows. Our joinery, paint and glazing workshops mean every part of the process stays in-house, under our control — from the first measurement to the final coat of paint.
All our craftsmen are directly employed by us. We don't use contractors. They work carefully and considerately in people's homes, and they share the same philosophy: restoration wherever possible, replacement only when necessary.
We specialise in Victorian, Edwardian and Georgian properties across all London boroughs, with extensive experience in conservation areas and listed buildings. Whatever the job, you'll get honest advice, skilled hands, and work you'll be proud of for years.
