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. 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. 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.

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. Time-served joiners who know timber, period detail and what actually works — guidance you can rely on from enquiry to installation.

High-quality bespoke joinery and glazing, at a fair and competitive price — proper windows and doors that last. 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.
