1. Broken sash cords.

Over time, sash cords can become fragile due to wear and tear, which can lead to sash cords breaking or snapping. If this happens, you will need to replace the cords on your sash windows. You might choose to follow a guide our team has written in the past on how to replace a sash cord, or if you don’t feel confident undertaking this task, contact our London carpenters who will be able to replace the sash cords in a timely manner.

2. Sash windows not staying up.

If your sash windows are not staying up, there might be a few things happening:

  • Sash weights are not balanced properly.
  • Wrong size weights.
  • Faulty component.
  • Components fell out of alignment.

If the sash window is heavier than the weights, it won’t stay open. If any of the window components have fallen out of alignment, it can lead to problems operating the window. So, it’s essential to inspect the sash window to figure out the problem and then assess the best way to deal with the issue. If there is a faulty component, it should be replaced.

3. Sash windows are stuck after painting.

So, you’ve painted over your sash window and now the window is stuck… it happens. You can easily unstick your window with a utility knife. Slide a utility knife along the edge of the window to gently break the paint seal. Then, gently loosen the window. Try raising the window – if it works, you’ve successfully opened a painted shut window.
