Kaizen Windows & Doors plans picture windows in Holywell around details that are harder to correct after finishing. The first control is frame position, and 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 picture windows scope. We then coordinate packers through opening dimensions, glass specification, frame support, drainage and perimeter sealing and support the frame at suitable points so fixing does not pull it out of line, with frame position kept as the lead check for this picture windows scope. Internal Sealing is checked before closure, while gaskets is included in final handover. We close the internal frame perimeter cleanly before trims or making-good work is completed and check glazing and sash seals for continuous seating before final handover, keeping the installation focused on a broad glazed area with the frame and glass coordinated to the opening, with frame position kept as the lead check for this picture windows scope.
