    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Thanks everyone for your help. After hearing what everyone has been saying, and talking to a guy who's been building houses for over 30 years, I have determined to make the adjustments at the beam. The main beam below the sloped area has definitely settled at the point where it rests on the...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Well, for my hump at the other side of the house, I read that I could just take a floor grinder/sander to it to level things off and make sure the nails/screws are below the surface enough so that they do not interfere. As for the slope along the exterior wall, I'm thinking that I want to...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Well, I would love to be able to leave it, but the slope is so steep for 2-3 feet from the wall that I will have to do something with it because I can't install the hardwoods with huge gaps underneath. I have one other issue that I discovered at the other end of the house. There is one...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    You are right, there is a joist for one half of the wall, and another joist for the other half, both meeting up in the middle over top of the main support beam. Both joists are completely lifted up off the main support beam, and still attached to the subfloor. The slope is steep enough to the...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Ok, here's some real life pictures. First one is a shot from the basement, and you can see the gap underneath the last joist before the wall, and there's even a tiny gap under the 2nd last joist. The 3rd joist from the wall is sitting on the beam. The second picture if from upstairs in the...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Well, you are close in your drawing, but the joists run parallel with the wall in question. So, you have the main beam that runs directly into the middle, perpendicular to this wall, and the joist running parallel with this wall and sitting on the main beam. Where the two joists (one for each...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Sorry, my camera is out of commission :( However, the gap is not between the plywood and the joist, it is between the joist and the main beam that would normally support its weight. The subfloor is screwed to the joist, so the subfloor still rests on the joist nice and flush with no gap...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Thanks Tool Guy! I'm pretty sure that is the issue as the main beam is perfectly level across the house. What happens if the joist doesn't drop after cutting it? For example, could the joist "warp" into that permanent position over time? If it doesn't drop, how could I pull the joist back...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Thanks a lot for taking the time to read my post. I did some research, and I am very confident that I have the same problem as the attached picture/article. If I were to cut the subfloor in the middle of the first joist (the joist that has a 1/4" gap underneath it between the joist and the...

    Subfloor slopes downward from exterior wall for 2-3ft then levels off...

    Hi Folks, I recently removed all carpets, laminate, etc. in my 35 year old house to expose the subfloor and prepare the house to install hardwood flooring. Along one of my exterior walls, there is a noticeable downward slope away from the wall that extends 2-3 feet (i.e. the width of one...
