I have been trying to find a good way to fix this problem for years, and here is what my issue is. When our house was built, the builder installed a door frame for our interior basement door at the bottom of the stairs to the basement. When they built the door frame, it was about 3/4" taller than the bottom of the floor trusses in the basement. But the people that installed this door frame went ahead and jammed it under the floor truss, and the result is a hump in the dining room floor.
I have since shortened the door frame, but the truss has not settled down to a level with the rest of the floor. So what I need to do is to pull the top of the truss down and keep it down so that the floor is flat. We want to replace the cheap wood flooring in our dining room and kitchen area, possibly with tile, and we need to remove this hump before we put in new tile. Any ideas out there?
