(Another entry in my series of questions on the world's slowest fencing project.)
I ended up with a bit of an awkward angle from a fence gate post next to a concrete slab to the house. So my solution was to use concrete anchors to attach a 4x4 to my slab (in a straight line from the gate post), and the I have a nice 90° angle from the 4x4 back to the house. Pictures below:
Now since I already had some 4x4 posts on this same slab acting as braces for the deck overhead (see the second picture, background), I figured I'd do the same with this one, paint it like the others, but also use it as a fencepost to make the strecth from that gate post to the house.
Here's the question: I've since read/remembered that its a Bad Idea to attach a fence directly to the house, as they are apt to move separately over time. I'm of course not going to nail cross-beams from that 4x4 to the siding, but I'm wondering if this 4x4 being attached to that top bean under the 2nd story deck counts, and if that is also a Bad Idea? Should I instead just trim the 4x4 to the height of the other gate post, and just use it like a post (but attached to the slab)? Was even attaching it to the slab a bad idea?
