Record the finish system
Product, colour, date and contractor details are useful.
Look for patterns
Peeling, staining or cracks in one area may deserve closer review.
Treat unexplained moisture carefully
Repeated staining should not simply be covered with new paint.
Plan safe access
Upper-storey work and unfamiliar cladding systems may require professional assessment.
