For casement window replacement in Hindley, the technical sequence begins with internal sealing, so we close the internal frame perimeter cleanly before trims or making-good work is completed, with internal sealing kept as the lead check for this casement windows scope. We then use handle positions to coordinate opening dimensions, hinge positions, handle access, locking points and clearances, and we check handle height and access against the room layout and opening style, with internal sealing kept as the lead check for this casement windows scope. Before closure, internal making good is reviewed and we repair or finish internal reveals, sill zones and decoration interfaces around the new frame, with internal sealing kept as the lead check for this casement windows scope. The handover also covers reveal dimensions; we check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, with internal sealing kept as the lead check for this casement windows scope. Together these checks support casement windows that open cleanly and suit the intended ventilation pattern.
