Name the material
Ask whether the proposed fence is steel, aluminum or another material. Request the finish specification and manufacturer care instructions. Similar-looking panels can have different repair and maintenance requirements.
Plan visibility and access
Discuss spacing, gates, locks and how the design meets your intended use. If a pool or another regulated feature is involved, confirm the applicable requirements with the responsible authority before selecting a style.
Compare installation details
Ask how posts and panels will be installed on your terrain and how damaged finish areas are treated. Compare material, labor, gate hardware and cleanup as separate parts of the estimate.
