Usually the first stage of a tree inspection is carried out from the ground, using binoculars to assess the upper crown. Occasionally a potential fault in the upper crown or stem is identified at this stage, but it is not possible to determine the extent of the issue.
Depending on the issue this can sometimes be confirmed with the use of a drone that, armed with a high definition camera, enables a closer look. However, there are circumstances when there is a need to get up close to the potential fault to enable a full assessment. We have fully qualified tree climbers able to carry out this level of inspection.
