I noticed this skinny picket in our fence after the walk through and after the crew left. How much would this bug you? Should I have them come back and replace it with a full sized picket? The owner of the fence company says they had to do that for spacing blah blah. I don’t believe him. I think it’s because the fence builder made the facia and the 2x4 rail too close and a normal sized picket wouldn’t fit in between them.
