On this draught-reduction windows project in Disley, locking points is the first installation control and we align sash locking points and keeps so the window closes evenly around the frame. Kaizen Windows & Doors links hardware adjustment to frame fit, gaskets, locking compression, perimeter seals and reveal condition, making sure we adjust hinges, handles and locking hardware after glazing so operation remains smooth, with locking points kept as the lead check for this draught-reduction windows scope. We also review opening survey before making good and check the existing opening, frame position and surrounding finishes before final dimensions are confirmed, with locking points kept as the lead check for this draught-reduction windows scope. Finally, fixing points is checked so we can position frame fixings to suit the opening, frame profile and surrounding substrate, helping deliver a tighter window installation with frame and sash sealing checked together, with locking points kept as the lead check for this draught-reduction windows scope.
