Kaizen Windows & Doors plans side-hung windows in Poynton around details that are harder to correct after finishing. The first control is final checks, and we open, close, lock and inspect each installed window before the work is handed over, with final checks kept as the lead check for this side-hung windows scope. We then coordinate sill level through hinge side, handle reach, opening clearance, locking points and reveal depth and coordinate the frame base with the internal sill or window board and the external weathering detail, with final checks kept as the lead check for this side-hung windows scope. Perimeter Sealing is checked before closure, while keeps is included in final handover. We form a continuous weather-resistant seal around the external frame perimeter and adjust keeps to achieve consistent engagement without making operation unnecessarily stiff, keeping the installation focused on side-hung windows with operation planned around the adjoining room, with final checks kept as the lead check for this side-hung windows scope.
