The Sash Window Painting Specialists

Our Services

At The Sash Window Painting Specialists, everything we do is tailored to your windows and your home. Our team of skilled craftsmen has the expertise to restore sash windows of any age or condition — and crucially, we never require scaffolding, keeping disruption to an absolute minimum.

We offer two distinct restoration routes depending on the condition of your windows and your preference:

On-Site Restoration

We carry out all stripping, repairs, draught-proofing and painting at your property, with no need for scaffolding at any stage.

Workshop Restoration

For windows requiring more intensive work, we carefully remove your sashes, carry out a full restoration in our specialist workshop, and reinstate them to a perfect finish. Again, no scaffolding required.

Whichever route is right for you, we cover a comprehensive range of issues:

• Wood decay and rot
• Draughts and poor insulation
• Sticking, rattling or broken sashes
• Cracked or damaged glazing bars
• Failed or missing putty
• Glass repairs and replacement
• Broken sash cords and pulleys
• Worn or damaged ironmongery
• Frame and box repairs

At The Sash Window Painting Specialists, we never cut corners. Every window we restore follows the same meticulous process — each stage carefully completed to ensure your sashes perform beautifully and look the part for years to come.

1. In-situ or Workshop — All of our work is carried out either at your property or in our specialist workshop, depending on the level of restoration required. Either way, we never need scaffolding — keeping your home accessible and disruption to a minimum.
2. Inspection & Repairs — We begin with a thorough assessment of each window, identifying any areas of damage, decay or weakness. Problem areas are carefully isolated and repaired using bespoke hardwood pieces shaped to match your existing frames, ensuring a seamless and lasting result.
3. Stripping — Where painting is required, we remove all old, flaking paint from the sashes and frames by hand. This step is essential — paint build-up is one of the most common causes of sticking sashes and poor performance, and a clean surface is the foundation of a long-lasting finish.
4. Glazing — Where required, we replace cracked or inefficient glass, re-bed panes in fresh putty and reseal around glazing to improve both thermal efficiency and weather resistance.
5. Draught-Proofing — We fit a specialist brush pile and compression seal system throughout the window, forming an effective barrier against draughts without affecting the smooth, balanced operation of the sashes.
6. Sash Cord & Pulley Restoration — Where cords are worn, broken or missing, we replace them using traditional materials to restore the correct balance and smooth operation of every sash.
7. Painting — Finally, we apply a meticulous hand-painted finish using only the finest quality paints in your chosen colour and sheen, giving your windows maximum protection and a result that enhances your home for years to come.

London’s Sash Windows Through the Ages

The Sash Window Painting Specialists have spent years working on London’s remarkable original sash windows. That experience has given us not only deep technical knowledge, but a genuine admiration for the craftsmanship and architectural character found across the capital.

London’s sash windows tell the story of the city itself. Each era brought its own distinctive style, and those details are still visible today on streets throughout the capital.

Georgian: 1714–1837

The sash window as we know it came of age during the Georgian period. Elegant, symmetrical and deeply considered in their proportions, Georgian sash windows are among the finest examples of British craftsmanship anywhere in the world. Typically featuring six-over-six pane configurations with slender glazing bars and flush frames set deep into the brickwork, they were designed to complement the restrained, classical architecture of the era. Many have now stood for well over 200 years — a testament to the quality of the timber and craftsmanship that went into them.

Victorian: 1837–1901

As glass manufacturing advanced and became more affordable, Victorian sash windows grew larger and more elaborate. Two-over-two configurations became increasingly common, with bigger panes replacing the intricate multi-pane designs of the Georgian era. Decorative horns — the distinctive curved projections at the top of the lower sash — became a hallmark of Victorian windows, as did ornate architraves and more decorative surrounds. Stained and etched glass also made an appearance, adding colour and artistry to the Victorian streetscape.

Edwardian: 1901–1910

Edwardian sash windows brought a lightness and simplicity that set them apart from their Victorian predecessors. Larger panes of glass, often in a two-over-one or one-over-one arrangement, gave homes a brighter, airier feel. The heavy ornamentation of the Victorian era gave way to cleaner lines and more refined detailing — elegant without being excessive. Many Edwardian windows also featured leaded lights in the upper sash, adding a touch of craftsmanship while maintaining the period’s characteristic restraint.

Interwar: 1919–1939

The interwar years saw sash windows begin to share the stage with new window styles, but they remained a common feature across London’s growing suburbs. Designs became more varied, often reflecting the optimism and energy of the period. Some retained the elegance of earlier eras, while others took on bolder proportions and simpler detailing to suit the more functional architectural styles of the time.

Modern: 1945–Present

Despite the widespread adoption of uPVC from the 1970s onwards, original sash windows have never lost their appeal — and in recent decades, appreciation for them has only grown. Where uPVC requires full replacement every few decades, a well-maintained timber sash window can last indefinitely. Modern timber sash windows continue to draw on the heritage of earlier periods, with traditional proportions, authentic glazing bar profiles and classic painted finishes remaining as desirable as ever.
