Kaizen Windows & Doors plans window replacement with timber boards in Ramsbottom around details that are harder to correct after finishing, with external making good kept as the lead check for this timber-board reveal windows scope. 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 timber-board reveal windows scope. We then coordinate frame position through board depth, frame setback, end returns, seal line and decoration 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 timber-board reveal windows scope. Cavity Closure is checked before closure, while sealant joints is included in final handover. We check the window perimeter where the opening meets cavity closers or insulated reveal construction and allow a practical perimeter joint for movement and a neat external seal line, keeping the installation focused on timber internal boards aligned neatly with the replacement frame and reveals, with external making good kept as the lead check for this timber-board reveal windows scope.
