Kaizen Windows & Doors plans new-build uPVC windows in Alderley Edge around details that are harder to correct after finishing. The first control is external making good, and we finish external reveals, render or masonry interfaces around the installed frame, with external making good kept as the lead check for this new-build windows scope. We then coordinate frame position through structural openings, cavity closures, damp interfaces, frame setting-out and render or masonry finishes and set the new frame at a position that works with the reveals, sill and external finish, with external making good kept as the lead check for this new-build windows scope. Cavity Closure is checked before closure, while perimeter sealing is included in final handover. We check the window perimeter where the opening meets cavity closers or insulated reveal construction and form a continuous weather-resistant seal around the external frame perimeter, keeping the installation focused on new-build windows coordinated with the surrounding wall construction before closure, with external making good kept as the lead check for this new-build windows scope.
