For uPVC windows with cottage-style proportions in Congleton, the technical sequence begins with frame alignment, so we check the frame for line, level and square before glazing and final tightening, with frame alignment kept as the lead check for this cottage-style windows scope. We then use hinge positions to coordinate mullion positions, opening lights, glazing bars, frame proportions and hardware, and we set opening sashes so hinge direction and swing work with the adjoining room, with frame alignment kept as the lead check for this cottage-style windows scope. Before closure, external making good is reviewed and we finish external reveals, render or masonry interfaces around the installed frame, with frame alignment kept as the lead check for this cottage-style 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 frame alignment kept as the lead check for this cottage-style windows scope. Together these checks support a more traditional visual arrangement delivered through a low-maintenance uPVC window system.
