Get your sash windows moving smoothly again

Sash cords connect the moving window to its counterweights. When a cord wears or breaks, the sash may become heavy, drop or fail to stay in position.

Signs that sash cords or pulleys need attention

A traditional sash window uses cords, pulleys and counterweights to help the sashes move. If a cord frays, breaks or comes away, the window may become difficult to lift or may not stay open. A stiff or noisy pulley can also affect operation.

Look out for a sash that drops, feels unusually heavy, rattles or will not remain in position. Avoid forcing a window that feels unsafe or jammed, as this may cause further damage.

Cord replacement and pulley checks

We inspect the window and its operating parts, then replace worn or broken cords where required. Pulleys can be checked and serviced, and the sash can be adjusted so the counterweights help it move as intended.

The work is carried out with care for the existing joinery. The exact process depends on the window’s design and condition.

Part of a wider window repair

Cord problems can occur alongside other issues, such as worn timber, poor alignment or draughts. If we find related faults, we can explain them and discuss whether further repair or refurbishment would help.

Sash Cords & Pulleys FAQ

How can I tell if a sash cord has broken?
The sash may drop, become difficult to lift or stop staying in position. A broken cord may also be visible inside the window box.
Do you replace pulleys as well as cords?
We can inspect the pulleys during the work and discuss servicing or replacement if a pulley is damaged or not operating properly.
Can I keep using a window with a broken cord?
A sash that is unbalanced or drops unexpectedly can be difficult to handle. Avoid forcing it and arrange an inspection.
Can cord replacement be combined with other repairs?
Yes. If the inspection identifies other issues, such as damaged timber or draughts, we can discuss suitable work alongside cord replacement.
