Kaizen Windows & Doors plans bay-window replacement in Wem around details that are harder to correct after finishing. The first control is reveal dimensions, and we check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, with reveal dimensions kept as the lead check for this bay windows scope. We then coordinate packers through bay geometry, frame angles, head support, sill or base line and internal reveals and support the frame at suitable points so fixing does not pull it out of line, with reveal dimensions kept as the lead check for this bay windows scope. Internal Sealing is checked before closure, while internal making good is included in final handover. We close the internal frame perimeter cleanly before trims or making-good work is completed and repair or finish internal reveals, sill zones and decoration interfaces around the new frame, keeping the installation focused on a bay-window assembly with linked frames aligned around the existing geometry, with reveal dimensions kept as the lead check for this bay windows scope.
