I just posted another ask about this but very soon I have another. I'm around to install bamboo flooring. I'd similar to to put it over my existing hardwood floor (which has be covered with runner since long before I owned the house). I a moment ago took up the carpet and am prepping the floor. One problem is that the existing floor squeaks, ALL OVER. Does anyone own recommendations for eliminate the squeaks before I install the up to date stuff? I've run some nails and screw into the joists and they come across to help but it seem like I'll call for a ton of them for this.

Also, when I install the new stuff, which is tongue and groove, should I install it straight up to the existing flooring or parallel? The existing floor is already perpendicular to the floor joist.

Thanks for the suggestions.
