That would never happen here, where the frost line is nominally 12" but is in fact zero. I thought those were the cute little truncated cement "booties" that were real popular here with deck scammers till only this year the state adopted deck design codes. Before, they were only by reference to a deck manual, sort of like the pirates' code, just "guidelines". Good call. I did not mention that, but I thought someone might point it out. The deck actually dropped very little at the house. It looks like the footings heaved out of the ground. Click to Enlarge 80.41 KB Click to Enlarge 77.16 KB
