The honest answer to "what does a fence cost" is that it depends on four things: how many linear feet, what material, how many gates, and what we'll be digging in. A written estimate pins all four down, which is why we don't quote over the phone. But there's a reliable order of magnitude between materials that helps you plan.
Chain link is the least expensive per foot, which is why it's the default for large lots and commercial yards. Wood comes next, with cedar and redwood privacy fences costing more than picket or ranch-rail because of the extra material. Vinyl costs more than wood up front but nothing after that. Wrought iron is at the top, and it's usually chosen for the front of the property where the look matters most.
Gates are their own line item. A walk gate is straightforward. A double-swing driveway gate needs heavier posts, deeper footings, and better hardware, and if you want it prepped for an opener, that's worth deciding before the posts go in rather than after.
The last variable is the ground. Caliche, rock, and old concrete footings from a previous fence all slow down post setting, and a good estimate says what happens if we hit them. Ours does. Every Banda's Fence estimate is free, itemized by footage, material, and gates, and written so you can compare styles on the same footage without guessing.
