For renovation window package in Ellesmere, the technical sequence begins with removal sequence, so we remove existing frames in a controlled order to protect the opening and adjoining finishes, with removal sequence kept as the lead check for this renovation windows scope. We then use frame dimensions to coordinate strip-out, reveals, sill finishes, decoration, external finish and trade sequence, and we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with removal sequence kept as the lead check for this renovation windows scope. Before closure, fixing points is reviewed and we position frame fixings to suit the opening, frame profile and surrounding substrate, with removal sequence kept as the lead check for this renovation windows scope. The handover also covers internal sealing; we close the internal frame perimeter cleanly before trims or making-good work is completed, with removal sequence kept as the lead check for this renovation windows scope. Together these checks support replacement windows integrated into the wider renovation rather than treated as an isolated trade.
