Wobbly Newel Post
I have a very wobbly newel post at the end of a short balustrade at the top of our stairs. It is the simple solid kind. (Not like the big hollow kind I saw repaired on a This Old House video.) Interested in a simple fix, I got a long drill bit and drilled two diagonal holes through the post into the (subfloor?). Then I screwed in two extra long wood screws. They were long enough to sink a good 1 1/2 - 2 inches into the subfloor. But whatever is under there, it wasn't solid enough to provide anything for them to bite into and it wobbled just as loosely as before. I don't know much about home construction. Any ideas why I seemed hit air?
I am interested in the simplest solution to fix this safety hazard. I'm guessing I'll need to disassemble the balustrade, remove the post and then I imagine I'll see what the problem is with the subfloor. But I'm holding off in case there is an easier way.
