ISLEWORTH, WEST LONDON – Refurb-a-Sash Ltd, one of the capital’s most respected providers of sash windows London-wide, has announced the continued expansion of its specialist joinery and glazing services across West and South West London — marking 33 years of handcrafting replacement and refurbished timber sash windows for some of the capital’s finest period properties.
Established in 1992, the company was founded with a single, clear purpose: to offer London homeowners a genuinely sympathetic alternative to replacing their original Victorian, Edwardian and Georgian sash windows with uPVC. Three decades on, that founding principle remains unchanged. Today Refurb-a-Sash operates from a 13,500 sq ft purpose-built workshop in Isleworth — one of the largest dedicated sash window manufacturing facilities in London — with every product still handmade on-site by its own directly employed team of time-served craftsmen.
The company’s approach to production is uncompromising. All timber is carefully selected, preservative treated and hand-prepared before spray painting in durable, long-life coatings. Joinery is produced using a combination of traditional hand skills and the latest woodworking technology, with glazing, finishing and quality control all handled in-house from start to completion. Refurb-a-Sash never uses subcontractors — every installation is carried out by its own PAYE, reference-checked employees using company vehicles and equipment. Windows are available single or double glazed, with a range of specialist options including acoustic glass, triple glazing, textured glass and stained glass panel rebuilds.
A Complete Service for Period Windows & Doors
The full service portfolio encompasses sash window repairs — covering draught proofing, security upgrades, broken cords, imbalanced frames and stuck sashes — which remains the most cost-effective solution for many well-built original windows. For properties where more extensive work is required, the refurbishment service combines repair with the installation of new frames and sills, plus optional single or double glazing upgrades.
For properties where original windows are beyond economic repair, Refurb-a-Sash offers a complete ‘back to brick’ replacement service for box sash windows, casement windows and French door frames, sills and surrounding mouldings — all manufactured to faithfully replicate original period features. The company also provides specialist acoustic glass for properties affected by road or aircraft noise, triple glazing, textured glass and stained glass panel rebuilds, with particular expertise in listed buildings and conservation areas.
