Framing and Sub-Flooring - Noticeable slope on main floor...

Hi folks,

I just purchased a house built in 1972 and there's a noticeable hump at the main center support beam and sloping to the front and back of the house. The main beam is supported by 3 steel adjustable teleposts/columns, and I was wondering what was the best way to effectively lower/adjust the teleposts?

Thanks in advance!

Whoa there. The slope is away from your main beam, correct? Have you inspected where the floor joists attach to your beam? Have you inspected the other ends of you floor joists. Somewhere the floor joist have settled. Somewhere they need to be pushed back up.

I don't think anyone would recommend lowering your main beam to even the floors.

I have dealth with this. The majority of my floor joist only had 2 nails in them, and the rested on a ledger with 1 nail every foot. I had to jack up all the joists and reattach them to the beam with joist hangers. It was a lot of work.

Here's a thread from another site where I posted some pictures with explanations. You will need an account to view the pics unfortunately. If you don't have an account, I can email the pictures to you. I hope this clears it up a bit...

Yes, correct. Floor joists look fine at both ends. When you look along the foundation walls, there are cracks about a meter from the wall along all 4 walls with the slightest slope from the cracks towards the bottom of the wall. I assume over time the entire foundation has settled on the outer edges leaving the inner floor at the same orginal height, or close to it. The flooring inside the foundation walls is floating and this is where the pillars for the teleposts are located. Therefore, the pillars for the teleposts, do not move if the outer walls move.

I hope this clears things up...
