Window performance on this new-build windows installation in Rochdale depends on more than the frame profile. We start with internal making good and repair or finish internal reveals, sill zones and decoration interfaces around the new frame, with internal making good kept as the lead check for this new-build windows scope. frame dimensions is then coordinated through structural openings, cavity closures, damp interfaces, frame setting-out and render or masonry finishes, so we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with internal making good kept as the lead check for this new-build windows scope. Before final finishing, we review head interface and coordinate the frame head with the retained lintel, cavity closure and internal reveal, with internal making good kept as the lead check for this new-build windows scope. We finish with drainage paths and keep designed frame drainage routes clear through installation and external finishing, supporting new-build windows coordinated with the surrounding wall construction before closure, with internal making good kept as the lead check for this new-build windows scope.
