I am planning to remove carpet in a living room and dining room area of my house and replace it with floating laminate flooring. There are some spots in my current floor that squeak so I was planning on using an impact driver to drive down some screws from above the subfloor to the joists below.
I currently did not remove my carpet or tack strips yet but I was wondering is there a trick to find the joists underneath the subfloor? Also, what screws would be best for this job? I was currently looking at Senco 08F200Y Duraspin Number 8 by 2-Inch Subfloor Collated Screws. I didn't know what length of screw would be best for the job.
Also, underneath my living room and dining room subfloor is my basement which is unfinished so I could look up to see where the joists are. For the most part they are 24 inches apart on center however there are some joists which are slightly less than 24 inches apart and in some areas its about 16 inches apart.
