So the GF has a two story house, maybe 10 years old, with squeaky floors. It's bad enough when her 14 year old, 4'11", 100 lb. athlete daughter walks across them, but when my 330 lb.-ish, former offensive lineman butt limps across, it's really bad.... She already wants to install new carpets, so that's a help, but what else is involved in stopping the squeaking? And yes, I do view this as an opportunity to buy new tools... Track saw, anyone? Maybe M18 impact driver? LOL
