The Window Refurbishment
Specialist
ASWS is a family managed business now into its third generation and 50th year as a specialist window refurbishment and replacement company. The company has evolved continuously since 1960 and we are now a leading figure in the window industry.
WITH SIX DECADES OF EXPERTISE AND INNOVATION
Since 1960, ASWS has grown into one of the UK’s leading window refurbishment companies, specialising in steel and timber windows for heritage and commercial projects. Our evolution reflects an ever-changing industry – most recently expanding into a full design-to-implementation offering. This unique capability sets us apart, enabling us to support projects from early-stage surveys and consultation through scope development, PCSA works, sampling and testing, competitive tender, and final on-site delivery.
We have worked on some of London’s largest refurbishment schemes over the past decade. These include The Whiteley, Ikea 214 Oxford Street, Battersea Power Station, BBC Bush House, Hackney Town Hall, and Kensington Olympia. Our expertise spans off-site and on-site refurbishment of steel, timber, and aluminium windows, as well as heritage metalwork restoration and replacement – from steel frames to curtain walling and beyond.
ASWS is recognised as a leading figure in its field, collaborating with major contractors such as Laing O’Rourke, McLaren, Mace, BAM, Wates, Skanska, Wilmott Dixon, RED Construction, Collins, and John Sisk, as well as top architects and façade engineers including BDP, Buro Happold, Foster + Partners, Wilkinson Eyre, Hawkins Brown, MAKE, Arup, TP Bennett, and others. We regularly consult during RIBA Stages 1–3, guiding clients through planning and heritage constraints, and liaising directly with conservation officers. With the Whiteley, we worked closely with Westminster’s Head of Design, Conservation and Sustainability.
Our collaborative approach extends to project managers such as Avison Young, Gardiner & Theobald, Turner & Townsend, CBRE, JLL, and Exigere, ensuring seamless delivery on complex, high-profile projects. With three generations of family leadership and a reputation built on excellence, ASWS continues to combine traditional craftsmanship with modern sustainability goals helping clients achieve outstanding results on some of the UK’s most iconic buildings.
