Ask the quotation to identify the installation work, any separate building requirements and the inspection or follow-up included. Obtain applicable property permissions before proceeding. A clear proposal also states what is excluded, so you can arrange wall repairs, vegetation clearance or other work with the appropriate contractor.
At completion, retain the work description, relevant fence documents and equipment instructions. Ask for normal user operation to be explained and for any remaining items to be identified. If electric fence repairs are needed later, those records help the next technician understand the installed system without relying on a package name or a photograph of a similar unit.
