Neighbor behind me put up a new fence on the property line. I paid half, of course, but he wanted to do all the labor. The 4x4s used as posts looked fine.No joke on the lumber....
After a couple of months, one of them decided to just take a right turn half-way up. It warped so hard and fast it broke the fence. We had to add a wedge-shaped picket and a repair block to make the fence look right and I have no confidence it won't break again in another couple of months.
I didn't realize that a 4x4 could warp that much. Yes, he got the lumber from a local Home Depot.
