What Does a Sash Window Overhaul Involve?


A sash window overhaul is a comprehensive process that restores your windows to their original condition or better. The work typically includes:


  1. Inspection and Assessment

    A detailed examination of the window’s condition, identifying issues such as rot, broken glass, damaged cords, or faulty pulleys.


  2. Dismantling and Repair

    Carefully removing the sashes and repairing or replacing damaged components. This may involve splicing timber, replacing glazing, or fitting new sash cords.


  3. Repainting and Finishing

    Stripping old paint, sanding, and applying high-quality paint or varnish to protect the wood and enhance appearance.


  4. Draught Proofing and Weatherproofing

    Installing seals and brushes to improve insulation and reduce heat loss.


  5. Reassembly and Testing

    Putting the window back together and ensuring smooth operation and security.


Each step requires skill and attention to detail to preserve the window’s character while improving its function. A professional craftsman will provide a detailed plan and cost estimate before starting work.

How Much Does It Cost to Rebuild a Window?


Understanding the cost to rebuild a sash window depends on several factors. These include the size of the window, the extent of damage, the type of timber used, and any additional features such as decorative glazing bars. On average, rebuilding a sash window can range from £500 to £1,200 per window in London.


Here are some key cost considerations:


  • Materials: High-quality timber such as softwood or hardwood will affect the price. Reclaimed timber may be used for authenticity but can be more expensive.

  • Labour: Skilled craftsmanship is essential for period properties. Labour costs reflect the expertise required.

  • Glazing: Single or double glazing options impact the price. Heritage properties often require single glazing to maintain authenticity.

  • Additional Repairs: If the window frame or surrounding masonry needs attention, this will add to the cost.

  • Finishing: Paint or varnish quality and the number of coats applied influence the final price.


Requesting a detailed window repair cost estimate will clarify these factors and help you plan your budget accordingly.
