Kaizen Windows & Doors plans window replacement before decoration in Toxteth around details that are harder to correct after finishing, with frame dimensions kept as the lead check for this pre-decoration windows scope. The first control is frame dimensions, and we confirm manufacturing dimensions against the surveyed opening before the replacement frame is ordered, with frame dimensions kept as the lead check for this pre-decoration windows scope. We then coordinate fixing points through internal reveals, trims, plaster repairs, sealant and decoration order and position frame fixings to suit the opening, frame profile and surrounding substrate, with frame dimensions kept as the lead check for this pre-decoration windows scope. Internal Sealing is checked before closure, while trims is included in final handover. We close the internal frame perimeter cleanly before trims or making-good work is completed and coordinate internal or external trims with reveals, frame position and adjoining finishes, keeping the installation focused on window installation handed over ready for the planned internal finishing stage, with frame dimensions kept as the lead check for this pre-decoration windows scope.
