For window replacement before decoration in Cuerden, the technical sequence begins with waste handling, so we manage removed frames, glass and packaging so working areas remain clear through the replacement sequence, with waste handling kept as the lead check for this pre-decoration windows scope. We then use reveal dimensions to coordinate internal reveals, trims, plaster repairs, sealant and decoration order, and we check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, with waste handling kept as the lead check for this pre-decoration windows scope. Before closure, frame alignment is reviewed and we check the frame for line, level and square before glazing and final tightening, with waste handling kept as the lead check for this pre-decoration windows scope. The handover also covers glass specification; we match glazing type and pane configuration to the intended room use and project specification, with waste handling kept as the lead check for this pre-decoration windows scope. Together these checks support window installation handed over ready for the planned internal finishing stage.
