For front-elevation window replacement in Northwich, the technical sequence begins with frame position, so we set the new frame at a position that works with the reveals, sill and external finish, with frame position kept as the lead check for this front-elevation replacement scope. We then use packers to coordinate opening sizes, frame alignment, sill levels, external finish and internal reveals, and we support the frame at suitable points so fixing does not pull it out of line, with frame position kept as the lead check for this front-elevation replacement scope. Before closure, thermal junctions is reviewed and we coordinate the frame perimeter with insulated reveals or cavity details to limit avoidable cold bridging, with frame position kept as the lead check for this front-elevation replacement scope. The handover also covers trims; we coordinate internal or external trims with reveals, frame position and adjoining finishes, with frame position kept as the lead check for this front-elevation replacement scope. Together these checks support a more consistent front elevation with each frame aligned to the wider window package.
