Sash window
Sash Cord windows - Rope type
SASH window repairs or Double-Hung windows which usually comprise of two vertically moving sashes each of which are hung in balance either by by a pair of cords (double hung) running on pulleys with a cast iron weight concealed in a pocket. Each of the 2 weights weigh 1/2 the total weight of the sash.
Over time the cords start to fray and become fragile and eventually break. This can sometimes be accelerated by the effect of the suns ultra violet rays breaking down the fibres of the cord and the cord starts fraying.​
This requires a sash cord repair
​
For window sash repairs the sash has to be removed from the window to remove the portion of the sash cord attached to the side of the sash. Then the window frame has to be opened up to access the sash weight. A new cord has to be strung over the pulley or guide and attached to the sash at one end and the weight at the other end before re assembling the window.
​
Other Sash window problems can occur when the glass is changed.
​It is not uncommon to find windows that slowly drop although the sash cords are intact, connected to the weights and free running.
This often occurs when the glass has been changed from the original and heavier glass has been fitted putting the sash out of balance.
this problem can be rectified by adding extra weight to the balance.
