Repainting sash windows is a more involved process than painting a standard wall or casement frame, and when done properly, it’s what separates a finish that lasts two years from one that lasts a decade. At Restore My Window, our sash window painting service in London begins with a thorough preparation stage: stripping any flaking or failing paint, sanding back to a sound surface, filling any cracks or minor rot with appropriate wood filler, and applying a primer before any top coats are laid. Our timber window decorating service uses only premium-brand paints suited to exterior-grade timber, ensuring the finish is flexible enough to move with the wood through seasonal changes without cracking or peeling.

Yes,  exterior window painting is one of the most in-demand parts of our London painting service, particularly for period properties with original timber sash and casement windows. Wooden window painting on the exterior requires the right conditions, the right preparation, and the right products, bare or poorly primed wood exposed to London’s variable weather will deteriorate quickly if not treated correctly. Our team of experienced window painters and decorators assesses the existing condition of your frames before work begins, addressing any rot, gaps, or surface failures first. The result is a clean, durable exterior finish that protects your timber and restores the kerb appeal of your property.

As a general guide, timber sash windows on the exterior of a London property should be repainted every five to seven years, though this depends on the quality of previous decoration, the window’s exposure to direct weather, and whether any underlying repairs have been carried out. South and west-facing wooden windows tend to weather faster due to sun and rain exposure, and may need attention sooner. Regular repainting by an experienced sash window decorator is one of the most cost-effective ways to protect your timber frames long-term,  neglected paintwork allows moisture into the wood, which leads to rot that is far more expensive to fix than a routine redecoration. If your frames are showing cracking, bubbling, or bare patches, it’s time to repaint.
