Sash windows are iconic in many London homes, imparting a timeless elegance to any property. Proper maintenance is essential to ensure sash window longevity. Wandsworth Sash Windows has six steps for preserving your sash windows’ beauty and functionality. Whether you require repairs or replacements or seek to extend the lifespan of your windows, this guide will equip you with the necessary knowledge:


  1. Regular Cleaning for Radiant Appeal:

    Initiate your sash window maintenance routine with regular cleaning. Utilise a mild detergent or a specialised window cleaning solution alongside a sponge to eradicate dirt, grime, and dust. Pay meticulous attention to the tracks, frames, and sills. This simple yet impactful task can significantly enhance the appearance and functionality of your windows.

  2. Thorough Damage Inspection

    Conduct a meticulous examination of your sash windows to identify any signs of damage. Be vigilant for cracks, rot, or loose joints. Promptly addressing these issues can thwart further deterioration, potentially saving you from costly repairs.

  3. Lubricate Moving Parts for Seamless Operation

    Ensure the seamless operation of your windows, especially if they are older, by applying a silicone-based lubricant to the moving parts, including the pulleys, sash cords, and tracks; this reduces friction, allowing the windows to move effortlessly.

  4. Revitalise with Repainting or Refinishing

    If the paint on your sash windows is peeling or chipping, it’s time for a fresh coat. Adequately prepared and painted windows look splendid and provide an additional defence against the elements.

  5. Combat Draughts for Energy Efficiency

    Draughts around sash windows can lead to energy inefficiency. Consider using weather stripping or sealant to eliminate any gaps. Seek professional advice, such as from our experts at Wandsworth Sash Windows, to determine if double-glazed windows or other enhancements are needed to bolster insulation.
