Quick case study from a targeted inspected on this south coast property.
Clear to see here are the cracks from where the render has potentially de-bonded from the brickwork. Moss and plant growth indicate the presence of relatively high levels of moisture which penetrates through and could have potentially caused damp on the internal wall.
This is just one inspection scenarios that Sussex Drone Surveys can help you with so If you have any building which would benefit from a targeted inspection then please get in touch on alex@sussexdronesurveys.co.uk and 07974 308 637
