Typical Issues Addressed by Renovation Experts

  2. Snapped Sash Cords: The internal cables that link the window to the lead weights often fray and break over time.
  3. Rattling and Draughts: Gaps in between the sashes and the frame result in heat loss and sound pollution.
  4. Taken Pulleys: Metal sheaves can rust or end up being blocked with centuries of paint, making the window impossible to open.
  5. Distorted Sashes: Timber can warp with time, resulting in poor fitment and sticking.
