Bespoke Timber French Door Installers in London
French Door Installers London
At Golden Ratio, we specialize 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 are looking for a traditional Victorian style or a contemporary garden transition, our timber doors provide unmatched warmth, character, and structural integrity.
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. This means your doors won't warp in the winter or shrink in the summer. It is virtually rot-proof, sustainable, and carries a 50-year warranty against decay, making it the ultimate choice for long-term value.
Why Choose French Doors for Your London Home?
Period Authenticity
We replicate original Victorian and Edwardian profiles to satisfy conservation requirements and heritage aesthetics.
Thermal Performance
Combined with Low-E glazing, our timber doors provide natural insulation that uPVC and metal simply can't match.
Acoustic Insulation
The dense cellular structure of our premium hardwoods provides a natural sound barrier against London street noise.
Our Premium Timber Selection
We offer four distinct, high-performance timbers, each selected for its durability, grain character, and suitability for the London climate.
