When major works, such as window replacement, take place, effective mechanisms are in place to ensure that these are fully completed in line with the specification.  This includes ensuring that automatic smoke vents are not blocked either while the works are being carried out or through the installation of the new cladding.  Easy-to-use arrangements are in place to enable residents to highlight poor or defective workmanship, with a robust process for ensuring that matters are put right to the satisfaction of all parties.
