Renovation Process

A box sash window operates by counterbalancing the weight of the sash against weights attached to a cord and passed over a pulley. These weights travel up and down in a box, concealed within the window frame, hence the name Box Sash Windows. A dividing strip is often suspended within the box to prevent collision of the weights.

Every sash window repair is unique with it’s own problems and solutions. Below are the processes that we usually take to repair, restore and improve your sash window.

  • Sliding sashes are carefully removed and the condition of timber, cords, glass and pulleys are all individually examined.
  • Any rotten wood, would be removed and new softwood/hardwood would be used to replace like for like, or if beyond repair original profiles can be matched.
  • The bottom sash will have weather strips, routed into the top meeting rail and to the bottom of the sash.
  • The parting bead and staff bead that will be removed will be replaced with new beading, that is also weather stripped, to ensure that the window is fully draft and weather proof.
  • All cords are replaced; pulleys are serviced and sash weights adjusted to ensure perfectly smooth operation of the window.
Renovation

Traditionally a sash window has a 3mm gap around the sashes to allow the window to move. Inevitably this gap allows in draughts, dust and noise and also allows it to make annoying rattles.
This gap also allows for loss of heat from the home. The installation of the Cheshire Sash Window renovation system into each window seals this gap and actually improves on the original by:

  • Cutting out rattles.
  • Eliminating draughts.
  • Stops heat escaping.
  • Reduces external noise.

  • Our windows were in a very bad condition, because there was a lot of rotten wood on them at the beginning, which all had to be cut out and replaced, after Cheshire Sash Windows came to renovate them they now look back to their original form.

  • When we moved to our current house we found 4 original sash windows that had been painted shut and hadn’t been opened for years. Cheshire sash windows have now restored them to their former glory and added additional draft proofing. We then had Oliver back to repair an opener in another original window and asked him to keep as much of the old wood and glass as possible – this he did, beautifully. Oliver is a skilled craftsman with genuine enthusiasm and interest for the windows he renovates.
