It’s about 1ft from the wall. I do have access to the crawl space where I can access the joists directly. But, I don’t know what I’m looking for if I was to go into crawl space. Nor what tools to bring to fix.
Trying to fix a squeaky subfloor prior to laminate install. I have fixed about 2/3rds of the squeaks by using 2in stainless steel screws. This squeak in the video I can't seem to fix. Any ideas?
