On this upper-floor windows project in Edge Hill, surface protection is the first installation control and we protect floors, worktops and nearby finishes while removal and installation work is carried out. Kaizen Windows & Doors links frame position to external access, frame handling, restrictors, sill height and making good, making sure we set the new frame at a position that works with the reveals, sill and external finish, with surface protection kept as the lead check for this upper-floor windows scope. We also review frame alignment before making good and check the frame for line, level and square before glazing and final tightening, with surface protection kept as the lead check for this upper-floor windows scope. Finally, gaskets is checked so we can check glazing and sash seals for continuous seating before final handover, helping deliver upper-floor windows installed through a sequence planned around safe access and operation, with surface protection kept as the lead check for this upper-floor windows scope.
