You can spend money on maintenance, sealing cracks and adding control joints, however, this will not resolve the issue as the plaster cladding system as a whole is at fault. As recognised by the building authorities, the only approved way to fix a leaky building and obtain a new code of compliance certificate is to reclad it.
This is because it is impossible to know the extent to which the structural integrity of the house has been compromised until all the plaster cladding has been removed. It is not always possible to see all the areas where the cladding or junctions have failed.
It is worth noting at this point, that from experience, we have found thermal imaging reports to be very unreliable at detecting and identifying elevated areas of moisture ingress within houses. Thermal imaging is too dependant on the seasons and recent weather conditions and does not give an accurate overview of what is occurring behind your cladding.
