On this pre-decoration windows project in Cadishead, final checks is the first installation control and we open, close, lock and inspect each installed window before the work is handed over, with final checks kept as the lead check for this pre-decoration windows scope. Kaizen Windows & Doors links sill level to internal reveals, trims, plaster repairs, sealant and decoration order, making sure we coordinate the frame base with the internal sill or window board and the external weathering detail, with final checks kept as the lead check for this pre-decoration windows scope. We also review perimeter sealing before making good and form a continuous weather-resistant seal around the external frame perimeter, with final checks kept as the lead check for this pre-decoration windows scope. Finally, opening configuration is checked so we can confirm fixed and opening sections against ventilation, access and furniture or worktop positions, helping deliver window installation handed over ready for the planned internal finishing stage, with final checks kept as the lead check for this pre-decoration windows scope.
