[Duplicate thread] Removed old carpet and floor is heaving in line with stairs

Hello,
Im currently renovating the main floor on my older home (built in the 70s) and the next step is tiling everything. As i was ripping out some older carpet i noticed the floor was heaving right in line with the stairway, i cut out a peice of the subfloor but its still out of level i believe there is a telepost right underneath. I just wanted to get some opinions on how to approach this situation, and what may have caused this problem? Please let me know if u need anymore information this is my first time posting on the forums. Ive attached some pictures
Thanks

Welcome to the forums!

Is one side heaving or is the other side sagging? I'd suspect that the low side is settling. Hard to say why from here, could be a structural issue or possibly foundation.

I would use luan (heavily nailed every 3 inches) or floor leveler to even it out. It probably was like that from the start and knowing that carpeting was being used it made little difference to fix it. As long as it's firm and stable I would not worry about it.

Looks like you have 1/4" or 3/8" ply over your plank flooring. Not stiff enough in my opinion for tile. You need to remove the top layer and replace with 3/4" T&G Advantech (or similar) subfloor. The thicker material will bridge the gap and smooth out the transiton. You then will install 1/4" cement backer board set in a troweled bed of thinset and screwed to the subfloor.

If you have the size and spacing and span information on the floor joists that is an important factor as well.
