Weather preparation should address moisture, drainage and the building's condition, not cover visible symptoms.
Investigate before painting
Find the cause of damp, leaks or mould and arrange suitable repairs. Paint is not a remedy for water ingress. Balance draught control with the ventilation required for the home and any appliances.
Work safely outside
Check accessible drains and surfaces, but use suitable professionals for roof, gutter and regulated work. Do not disturb suspected asbestos. Consider insulation and heating as part of a complete assessment rather than assuming one product solves every problem. In a rental, report faults and coordinate access through the agent.
