French Door Installers London
At Golden Ratio, we specialise exclusively in the design and installation of bespoke timber French doors. Unlike mass-produced alternatives, our doors are handcrafted from premium, sustainable timbers to complement the unique architectural heritage of London properties.
Whether you're after a traditional Victorian style or a contemporary garden transition, our timber French doors deliver unmatched warmth, character and structural integrity — a genuine upgrade on uPVC or aluminium that lasts for generations.
Why We Recommend Accoya® for London French Doors
External doors face the brunt of the UK weather. While traditional softwoods can swell and stick, Accoya® wood is modified to the core for incredible dimensional stability. That means your doors won't warp in the winter or shrink in the summer.
It's virtually rot-proof, fully sustainable, and carries a 50-year warranty against decay — making it the ultimate choice for long-term value and a flawless painted finish.
