Looking for advice on leveling (or more accurately, flattening) a floor before installing subfloor. I'm down to the joists and have one joist that's lower by approx 1/8" than the two adjacent joists. Sistering is not feasible due to plumbing/HVAC. Can I rip down some 2x4 shims to glue and...

Thanks for your help guys... Drive safe!;)

C.J., Looks like the NWFA spec for parallel installation is a 2nd layer of 1/2" giving a total thickness of 1 1/4". I was just wondering if 3/8" with 2" x 4" bridging would be stiff enough or is this a potential problem (other than the underlayment fastner length)? Joists are 2" x 8"...

Reposting from the Hardwood Floors section to see if I can get additional feedback... Hope that's ok. Add bookmark #1 Hey everyone, thanks for taking the time to help. In short, want to make sure I have the sub-floor properly spec'd... I removed old flooring (4 layers - 1 carpet, 3 wood) down...

Thanks for the input, Dan. I am aware that the NWFA spec is a 2nd layer of 1/2". I was just wondering if 3/8" with 2" x 4" bridging would be stiff enough or is this a potential problem? Again, the 3/8" was to avoid transitions in adjacent room's floor. Any thoughts on clip head ringshanked nails?

Thanks for your feedback, JP. I would go with a 2nd layer of 3/4" but the additional height would make it difficult to merge with the existing hardwood in the adjacent rooms without adding a transition. I was hoping that the bridging and sistering would allow for an underlayment of 3/8" on top...

Hey everyone, thanks for taking the time to help. In short, want to make sure I have the sub-floor properly spec'd... I removed old flooring (4 layers - 1 carpet, 3 wood) down to joists in most areas where feasible... there is some remaining 1 x 10 plank sub floor. I need to run the new 3/4...
