Some fence styles are easier to build than others. Installing metal fencing or walls is typically best left to professionals. Wood fencing can be handled by DIYers with solid building experience, but it is often worth engaging a professional to ensure a quality build that will endure over the years. Most fences require installing posts with concrete footings, a task that many can manage, but which requires precise execution to avoid big structural problems down the road. Some fences also require permitting, which is something local contractors have experience navigating.
