Hello,
I am new to this site so I hope I do this right. I have prepared an upstairs bedroom for laminate flooring. Everything is clean and free of staples etc. As I was running a level across the floor today I noticed a hump in the subflooring over 1 individual joist. There is a difference of about 3/8 - 1/2” from that point back to the level area. It runs along about a 3’ span over that 1 joist. There is duct work int that area as well. Any ideas other than rip it up, as to what I could do? Thanks for any info.

Open it up and mark the joist level with the others and nail a straight edge to the side low enough so the saw table can ride the straight edge. Usually near 1 1/2"

Making it level isn't that as important as just have a true plane between the other joists make a jig that you can use to mark the plane.

I appreciate the advice. Unfortunately I found out this morning that the subflooring is not only nailed and screwed but is glued (adhesive) as well. Do not have the time to rip it up and start again. Either gonna try and lay laminate as is or have carpet installed. Thanks again.

Can you plane/sand down the proud spot?
