Electric fence fault finding can establish the concern before a repair is selected. Ask whether the quotation covers investigation, agreed components, associated work and the relevant follow-up. If two proposals differ, check whether they describe the same installation and outcome; a smaller total may simply contain less work.
If you prefer a new electric fence installation, explain the intended boundary and obtain applicable owner or shared-property approval. Consider the practical operating and maintenance information the occupant will need afterwards. Keep the completed-work description and relevant certificate available, even when someone else helped arrange or pay for the work.
