On this brick-reveal windows project in Lydiate, perimeter sealing is the first installation control and we form a continuous weather-resistant seal around the external frame perimeter, with perimeter sealing kept as the lead check for this brick-reveal windows scope. Kaizen Windows & Doors links internal making good to reveal dimensions, frame setback, fixing positions, sealant joint and sill line, making sure we repair or finish internal reveals, sill zones and decoration interfaces around the new frame, with perimeter sealing kept as the lead check for this brick-reveal windows scope. We also review frame dimensions before making good and confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with perimeter sealing kept as the lead check for this brick-reveal windows scope. Finally, head interface is checked so we can coordinate the frame head with the retained lintel, cavity closure and internal reveal, helping deliver a frame position coordinated with visible masonry reveals and external sealing, with perimeter sealing kept as the lead check for this brick-reveal windows scope.
