A detailed inspection is recommended when a standard ground-level survey cannot fully determine a tree’s condition. This often includes cases where defects, cavities, fungal fruiting bodies, storm damage, or site changes suggest there may be hidden structural or root-related issues. These advanced assessments provide the deeper insight needed to make safe, defensible management decisions.

We use a combination of specialist techniques depending on the issue and the tree’s location. These may include aerial (climbing) inspections, drone surveys, sonic tomography, micro-drilling, and air spade root investigations. Each method targets specific concerns—such as internal decay, canopy defects or root disruption—and allows us to build a complete, evidence-based picture of the tree’s condition.

Most methods are non-invasive, such as drone imagery, sonic tomography and air spade root investigations. Where invasive techniques like micro-drilling are used, they are extremely small-scale and carefully targeted to minimise impact. These methods are only recommended when the diagnostic value outweighs the minimal disturbance caused.

You will receive a clear, professionally presented report including mapped tree locations, photographs, diagnostic results, and practical recommendations for management, remedial work or further monitoring. Where advanced instruments are used, you’ll also receive supporting outputs such as 3D tomography models or drilling profiles, giving you clear evidence to support decision-making and planning compliance.
