For bow-window replacement in Handforth, the technical sequence begins with frame position, so we set the new frame at a position that works with the reveals, sill and external finish, with frame position kept as the lead check for this bow windows scope. We then use fixing points to coordinate frame segmentation, connectors, sill line, head interface and internal finishing, and we position frame fixings to suit the opening, frame profile and surrounding substrate, with frame position kept as the lead check for this bow windows scope. Before closure, sealant joints is reviewed and we allow a practical perimeter joint for movement and a neat external seal line, with frame position kept as the lead check for this bow windows scope. The handover also covers trims; we coordinate internal or external trims with reveals, frame position and adjoining finishes, with frame position kept as the lead check for this bow windows scope. Together these checks support a multi-frame bow arrangement coordinated as one installation rather than separate windows.
