Sash Window Repair & Replacement Islington
Looking for expert sash window repair or replacement in Islington?
At MJ Kloss Carpentry, we specialise in restoring and replacing timber sash windows in some of Islington’s most distinctive period homes.
From elegant Georgian townhouses to classic Victorian terraces, including listed buildings, we carry out precise repairs, careful refurbishments, and bespoke sash window replacements that preserve the style and integrity of your property.
Islington’s Sash Windows
Islington is known for its beautiful mix of Georgian squares, Victorian terraces, and Edwardian houses, many of which still retain their original sash windows. These traditional features are a key part of the area’s architectural charm and continue to define much of Islington’s character.
Sash Window Repair Islington
Like all period features, sash windows can develop issues over time such as draughts, sticking sashes, snapped cords, or decayed timber.
Our sash window repair service in Islington addresses these problems using traditional joinery methods. We repair damaged timber, reseal and draught-proof frames, rebalance sash weights, and restore smooth, reliable operation—all while preserving as much of the original window as possible.
If a window is beyond repair, we also offer full sash window replacements, carefully crafted to match the proportions and detailing of your property so they remain in keeping with Islington’s period architecture.

Sash Window Replacement in Islington
Islington is home to some of London’s most recognisable period architecture, from elegant Georgian squares to charming Victorian terraces. Sash windows are a defining feature of these homes, but when frames become too damaged, draughty, or inefficient to repair, full replacement is often the best option. Our sash window replacement service combines modern performance with traditional style, preserving the timeless look of your property.
Bespoke Timber Sash Windows
Every sash window we make is built in our London joinery workshop, tailored to fit your home perfectly. Each design carefully reflects the proportions and detailing of your original windows. We use high-quality timber and traditional joinery methods to create durable, well-insulated sash windows that blend seamlessly with Islington’s period architecture.
Modern Glazing Options
For homeowners who want the best of both worlds, we offer modern glazing upgrades that maintain the traditional look while improving comfort. Slimline double glazing and specialist acoustic glass can increase energy efficiency and reduce outside noise, making your home quieter and warmer without losing its period charm.
Sash Window Refurbishment Islington
Not every sash window needs replacing—often, a little expert attention is all that’s required. Our refurbishment service in Islington covers painting, rebalancing, draught-proofing, and small timber repairs such as splicing or sill replacement.
