Common Issues Addressed by Renovation Experts

Sash windows are complex mechanical systems. Over years, layers of paint, wetness ingress, and structural settling can cause a number of typical failures. Remodelling experts focus on recognizing and rectifying these particular issues:

  2. Snapped Sash Cords: The internal cables that connect the window to the lead weights often fray and break gradually.
  3. Rattling and Draughts: Gaps in between the sashes and the frame cause heat loss and sound pollution.
