The Renovating Of Sash Windows
Renovating Sash Windows in London & the South-East Since 1985
Should you wish to completely renovating sash windows, recondition a sash window or simply need to remove the sashes to get large furniture into the property, then these guidelines can be used. Below guidelines are for the most common sliding box sash windows encountered. It should be remembered however that not every sash window works in exactly the same way and regional variations are not uncommon. We receive plenty of positive feedback from across the world regarding this DIY guide. Instructions below are written for work to be undertaken from inside of the property. All information is given to the best of our ability, but is given without any liability on our part.
Box Sash windows operate by counterbalancing the weight of the sash against weights attached to a cord and passed over a pulley.
These weights (generally cast iron or lead) 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, access to the weights is by means of a removable pocket, usually cut into the inside of the box lining but occasionally found in the box face behind wooden shutters. Parting beads are set into grooves running down the length of the linings, holding the pockets in place and separating the top (back) sash into its own channel. The channel for the bottom (front) sash is formed by the Staff Bead running around the perimeter of the lining.
