Window performance on this multi-storey window package installation in Euxton depends on more than the frame profile. We start with removal sequence and remove existing frames in a controlled order to protect the opening and adjoining finishes. frame dimensions is then coordinated through upper-floor access, frame handling, room sequence, protection and waste removal, so we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with removal sequence kept as the lead check for this multi-storey window package scope. Before final finishing, we review frame alignment and check the frame for line, level and square before glazing and final tightening, with removal sequence kept as the lead check for this multi-storey window package scope. We finish with external making good and finish external reveals, render or masonry interfaces around the installed frame, supporting a multi-level replacement programme with access and room order planned before installation, with removal sequence kept as the lead check for this multi-storey window package scope.
