For mixed-window replacement package in Shrewsbury, the technical sequence begins with fixing points, so we position frame fixings to suit the opening, frame profile and surrounding substrate, with fixing points kept as the lead check for this mixed-window replacement scope. We then use internal sealing to coordinate frame dimensions, opening types, hardware, glazing and installation sequence, and we close the internal frame perimeter cleanly before trims or making-good work is completed, with fixing points kept as the lead check for this mixed-window replacement scope. Before closure, hardware adjustment is reviewed and we adjust hinges, handles and locking hardware after glazing so operation remains smooth, with fixing points kept as the lead check for this mixed-window replacement scope. The handover also covers removal sequence; we remove existing frames in a controlled order to protect the opening and adjoining finishes, with fixing points kept as the lead check for this mixed-window replacement scope. Together these checks support different window types installed through one coordinated replacement package.
