On this plastered-reveal windows project in Macclesfield, internal sealing is the first installation control and we close the internal frame perimeter cleanly before trims or making-good work is completed, with internal sealing kept as the lead check for this plastered-reveal windows scope. Kaizen Windows & Doors links installation access to frame position, plaster edge, corner protection, sill finish and drying sequence, making sure we plan handling and working access before existing frames are removed, with internal sealing kept as the lead check for this plastered-reveal windows scope. We also review reveal dimensions before making good and check internal and external reveal depths so trims, plaster and handle clearances can be coordinated, with internal sealing kept as the lead check for this plastered-reveal windows scope. Finally, fixing points is checked so we can position frame fixings to suit the opening, frame profile and surrounding substrate, helping deliver plastered reveals finished cleanly around the replacement frame, with internal sealing kept as the lead check for this plastered-reveal windows scope.
