I'm a widow & bought a home in 2003. It's a ranch style home & I relied on the homeowner & realtor to be honest with me. There were cracks in corners the 4 foot doorway going in to the kitchen. The realtor said there was a jack under the house (crawlspace) He went under & cranked the house up some. The crack closed, I bought the house. Since that time, my closet door in my bedroom will not close. The front door will not close. I have to lift up & pull & engage the deadbolt. The regular door thingy no longer lines up & will not stay shut without the deadbolt. I came home from work last night at 10:PM & my back door (french doors) was wide open. I can't shut them now & have a chair propped up to keep it closed. Does this ALWAYS mean an expensive foundation problem? Can it mean I simply need to have the house jacked up again? I'm by no means wealthy and am looking for a permanent CHEAP fix. Any opinions will be appreciated.
Thanks

There is no way of knowing what the causes of your problems are nor the fixes. It might be part of the orginal problems or something completely different.

It might have nothing to do with the foundation and might be rot/termite damage.

I would hire a structural engineer to evaluate it and recommend fixes.

Now this will cost several hundred dollars.

But while "foundation repair" companies will often give free estimates to often they are going to sell their type of fixes rather than focus on what the houses problems are.

Thanks, My thoughts exactly on the foundation compainies. I'll check on structural engineers in my area. It's just good to know that this problem isn't ALWAYS foundation problems. Though none of the other problems you mentioned sound cheap either.
Thanks again.
