For landing and stairwell windows in Mossley Hill, the technical sequence begins with hardware adjustment, so we adjust hinges, handles and locking hardware after glazing so operation remains smooth, with hardware adjustment kept as the lead check for this landing windows scope. We then use surface protection to coordinate installation access, sill height, handle reach, restrictors and internal reveals, and we protect floors, worktops and nearby finishes while removal and installation work is carried out, with hardware adjustment kept as the lead check for this landing windows scope. Before closure, frame position is reviewed and we set the new frame at a position that works with the reveals, sill and external finish, with hardware adjustment kept as the lead check for this landing windows scope. The handover also covers frame alignment; we check the frame for line, level and square before glazing and final tightening. Together these checks support landing glazing fitted around practical access and controlled operation.
