Skirting and the Back Deck Part 1

So I never posted about the skirting. After the house was leveled I had the floors insulated and the skirting replaced as intended.

Much better than this.

Trench dug and mesh up

3 coats plus placeholder for vent

In order to reskirt the back of the house, my back deck had to be partially disassembled. It was going to cost about $200 to have it reassembled. No problem.

The back deck was in pretty sad condition. It was saggy, missing a lot of pickets, the rail wasn't regulation height and was twisted and warped.
 

Sad, saggy deck

Apparently, unbeknownst to me, it was also in imminent danger of collapse. Once disassembled, it was clear that whoever built it was completely clueless. Most of the posts didn't even touch the ground and some were spaced four feet apart. There were no posts at all at the corners next to the house and the entire deck on that side was "supported" by the three nails attaching it to the house. My $200 turned into a $3,000 problem.  I had the whole thing rebuilt salvaging as much of the wood as possible.

 

Notice the post stops at the deck surface level. Nothing supporting this corner at all.

Nothing supporting this corner either. Just those 3 nails holding everything up.

What the heck is going on here?
