It depends on the size of the job, but most fences can be installed in one to three days. There is no reason to have to wait days or weeks between when the fence posts are installed, and when the rails, gates, and the rest of the job is completed. This is the sign of an over-extended contractor. Avoid at all cost contractors that drag out the installation process for more than three days. An installation should always be completed without day gaps.
Guys how long roughly should it take to install a 300ft fence with 6 ft between posts so 50 holes. something similer to below. its just 2 of us doing it though and its for a contractor buddy and neither of us do fences. its going around his pool and is gonna be a arc shape not straight runs. hes thinking 3 days and im thinking over a week maybe 2 if she wants panels on both sides.
