Warped Wood Floors Due To Support Jacks

5 years ago

I bought a house in upstate NY that requires a good deal of structural repair. It was built in 1890. At some point someone installed support jacks in the basement and they are pushing up the first floor in several places. I haven't had a chance to release some of the pressure in these, which I will do as soon as I can get up there. But, I was wondering if these humps in the floors are likely to go down on their own? I should note that the joists themselves are being pushed up - so its not just a problem with the flooring and subfloor. The humps are not visible, but they are significant enough that there are several doors that will not open and close because of them. I don't mind floors that are somewhat uneven, so as long as the situation improves I would prefer to keep the original floors.

Take some pics. Usually it's difficult to level a house, much less go past level. Maybe something else is going on.

The jacks caused a problem when they were intended to fix one. Don't make the same mistake. Get a professional involved and address the underlying problem(s) rather than attacking just the most visible symptom(s).

Hard to fully advise from just a verbal description. I agree on getting a professional involved. The warped floors may settle back some when pressure is relieved. It may also be possible to achieve additional flattening afterwards, if needed, by positioning some 2X material under the floors and screwing through it into the bottom of the floors. A professional should be able to tell you if that would help.

I agree with the above statement 100 percent. Foundation problems and roof problems will be two of the most important things, you can do for your house, before you start to make it pretty.

You are correct. I failed to mention that all the girders/beams that sit on the sill and support the joists have been either entirely, removed, or removed and then replaced in some weird way. There is not a normal system of girders in place under the joists. I realize this needs to be fixed by a professional. I just want to know if it's possible for the joists and wood floors to even out a bit more once all this is fixed.

Why did you not address/ask about this when you were buying?

Incredible!

I've lived in 2 houses in upstate NY with cut up or rotted floor joists. Looks like you bought my last old house! Have no fear, there's always a solution. You may end up with more jack posts and cross beams, but as long as the sills haven't disintegrated, it can be easily fixed. It may not be level, but it won't feel like a rollercoaster.

I did realize the extent of the structural issues and the price reflects that. I would just prefer to keep the floors so.I can put money into other things.
