Why SPS Timber Windows

SPS Timber Windows is London’s most well-established and trusted manufacturer and installer of bespoke, energy-efficient and fully-finished Accoya® timber windows and doors, including traditional timber box sash windows, timber casement windows, timber French doors, timber front doors, timber single exterior doors and timber folding sliding doors.

Our products are made with meticulous attention to detail in our London workshops and all installations are carried out by our own teams of dedicated, highly skilled craftsmen, installers and decorators.

Each window and door is individually made to our customers’ requirements, be it the replication of an original or a custom made design.

Our experienced team can offer clear advice, supported by the latest CAD software, to assist in the realisation of individual designs or the authentic reproduction of period timber windows and doors.

By combining the best in traditional joinery and craftsmanship with the latest technology and finishes, our timber windows and doors are widely recognised for the superior quality of their construction, performance and finish and unrivalled accuracy of period designs and features.

Thermal energy performance is optimised with our “A” rated double-glazed units, which exceed the latest building regulation requirements, and all double-glazed installations are FENSA certificated and supported by an Insurance Backed Guarantee.

Our customers’ satisfaction is of paramount importance, for which reason we are committed to producing products of the highest quality and to offering the most comprehensive service we believe you will find, from consultation and design to the installation and final hand finishing of each window and door, including the thorough decoration of their surrounds.

It’s not just what we say, it’s what our customers say
