Take the 2-minute tour ×  My house is covered in stucco, I need
to hang something very heavy on it, but I assume I'll need to
know what's UNDER the stucco before I can attempt to hang
everything (I'm assuming the answer is different if it's wood
versus brick).  So what is the easiest yet least destructive way
to determine what's under stucco? Is it just drilling a hole in
it and looking then filling in that hole?  share|improve this

Since you're going to hang something on it, you're going to make
a hole anyway. Just make that hole your test hole, and if you
hit wood or brick, it will be pretty obvious with even a small
bit. Then get the appropriate bolt/screw for the wall, expand
the hole as necessary, and do the install.  I'd recommend
against checking from the inside since the first thing you'll
see is wood sheathing even if there's brick outside (unless
you're as unlucky as me and see sheet rock installed behind
aluminum siding, but I digress).
