This topic is kind of attached to an older topic "ceilings cracks". I recently went under our house to try what has been suggested for squeaky floors "tightening joist bolts" which worked for that issue but I found another issue which I think might be tied to the ceilings cracking.
There are two blocking piers that at first, looked like they were extra's left behind by the set up crew but after further inspection I think that for some reason they were taken out of place.
This was bought as a foreclosure and sat empty for three years, so any one could have gone under the house and done anything. The cement runners under all other piers that are in place have painted lines under them and there are lines where it looks like these two out of place piers came from, so I do think a re-level is in order like Yanita and Greg suggested previously. 
What should I look for as far as a qualified person to do the re-level? I contacted the two manufactured home companies here and they both recommended the same person without knowing it, but not sure that this means that he knows what he is doing. Any suggestions on questions that I might ask him to find out how qualified he is to do the job right? I’m not sure what other options I have (live in a rural area) besides doing it myself and I have no experience with re-leveling a home.
