My 50 year old house has very squeaky floors. I have reached the point
where I have decided to start replacing the sub floors in the upstairs of
my three level split house. I'm way past trying to repair the existing
floor. (I can hear my cat jump off the bed and walk across the floor).
I've tried to screw the floor down in one bedroom with poor results. I
have 3/4 inch oak over 1/2 in plywood sub floor. I took up the carpet and
started driving screws to both pull down the hardwood to the sub floor and
to screw through the hard wood and sub floor into the joists. This only
quiets very close to where the screws are, while the floor continues to
squeak within 6 inches of the screws. It appears that the nails holding
the hardwood down are squeaking as well as the nails that hold the sub
Short of using 300 screws to cover the floor I decided it was time for a
I will trash the oak flooring and the 1/2 plywood, replacing with 3/4 sub
floor plywood and 1/2 Homesote "Soundbarrier" and place sound insulating
bats between the joists, all to be covered by carpeting.
I'm going to glue and screw the sub floor to the joists and glue and screw
the "Soundbarrier" to the sub floor.
If I am satisfied with the results I plan on doing the rest of the floors
in the house.
My goal is to have a quiet floor as well to insulate the room directly
below the bedroom from noise.
Is my plan a good way to reach my goal?
I'd appreciate any suggestions as to materials and/or methods.
