About us
A family joinery workshop, thirty years in the making
Timber Sash Windows London is the windows-and-doors arm of a family joinery business with three decades in the trade. We are brothers James and Nick — sons of Gary — qualified joiners who have spent our working lives making things properly, in timber.
Our family
Three decades of joinery, kept in the family
Timber Sash Windows London is run by brothers James and Nick — sons of Gary, and, like him, time-served joiners. Between us we bring a lifetime in the joinery trade and 30 years of manufacturing behind the business, with the kind of hands-on knowledge you only gain from making things properly, in timber, year after year.
A full joinery workshop
More than windows and doors
Windows and doors are a major part of what we do, but they sit within a broader joinery business. Our own Worcestershire workshop specialises in bespoke staircases, oak-framed porches, car ports and garages through our sister business, Oak Porches Online — three decades of hands-on joinery experience that informs every window and door we supply.
Designed here, crafted by our partners
British design, expert European manufacture, installed by us
Our timber windows and doors are designed and specified in Britain, then expertly crafted by our trusted European partner workshops — skilled joinery factories we have worked with for years, geared up for the labour-intensive work of building and finishing quality timber windows. Every order is quality-checked and, as FENSA-registered installers, supplied and fitted by our own team across London and the wider UK — so the same people who advise you see the work through to a properly finished installation.
What we stand for
Expert advice
Time-served joiners who know timber, period detail and what actually works — guidance you can rely on from enquiry to installation.
Quality & value
High-quality bespoke joinery and glazing, at a fair and competitive price — proper windows and doors that last.
Bespoke, made to measure
Every window and door is made to your openings and your property, not adapted from a standard size.

Traditional proportions, authentic joinery and leaded lights for period, listed and conservation-area homes.
Bespoke timber windows and doors, made for your home
