Need some advice on my house.

Measure the windows; looking for level sills, plumb sides, and equidistant diagonals. If they pass;
Move to where the walls meet the main house;
on the outside, look for buckled siding.
on the inside, look for cracked drywall joints.

I'm no engineer, but IMO, if there are no concrete friction piers under those wooden columns, somebody deserves a punch in the head. and
IMO, there should have been more than just those three skinny columns out there; and THEN!, is the deck out back attached to the Sunroom?
Ima thinking it's time to call a structural engineer, followed by someone who knows code.
But I'm just a lawnmower mechanic........... what the 'ell do I know.

Windows in the sun room are rotted and need to be replaced (previous owners left them open in the rain), but some of them are a little difficult to open and close....

Interior of the sun room is knotty pine, so no way to tell if there's cracking going on there.

Exterior is shitty (and mis-installed!) aluminum siding, and that was going to be one of next years projects.

As for what's under those posts/columns, I have no idea, as that area has now been converted to one of my wife's gardens. But I'm not afraid to dig it up...

And, yes. The deck is attached to the sun room, and come to think of it, that door doesn't work properly.

Do Structural Engineers "specialize"? I deal with PE's and ME's quite a bit, and I know they do (specialize), but I've never dealt with a Structural Engineer before.

Thanks!
