Any professional fence contractor will have a procedure in place that the crew goes through before leaving the job. This should include the job foreman and at least one crew member walking the entire job site inspecting the workmanship and the post job clean up, ensuring everything has been completed according to the initial plan and intent. The final action should be a meeting with the homeowner to answer any questions, provide maintenance suggestions, and demonstrate any components like gates or removable panels. The final invoice should only be presented when the homeowner is totally satisfied with the end result.
