The first thing to go wrong with a new fence is almost always the gate. Soon the gate starts to sag or tilt out of alignment with the post on the latch side. In order to resolve those problems I bury all my posts 2 1/2' to 3' deep set in concrete. (mother nature can shrug her shoulders and move anything but the added depth reduces the tilt) Secondly, I build all my gates in a half lap fashion. This makes a ridged frame on which to place the cedar pickets. Thirdly, I use a superior hinge that is much stronger, cost the same as and is tighter than conventional gate hinges used by most every fence company. Most importantly I do all the work myself with helpers in order to maintain the quality of the project. I dont have sub fence crews who get paid by the foot and dont really care too much about the extra things needed in order to make a quality fence. Fences can look much better than just posts and pickets. By adding on just a little trim a fence can go from plain jane to beautiful. On all my fences I automatically add two trim pieces along the top, a 1x4 with a 1x2 on top of it. This really finishes off the fence for a better look. The 1x4s and 1x2s come from left over pickets used on the fence and take just a little time to apply to fence. I can also create a column look and add arched or stacked horizontal pieces between the columns.
