House leveling? About 2 years ago we had some work done in our bacment....

About 2 years ago we had some work done in our bacment. And the family that did the work took out the main support beam holding up the second horizontal and didn't put new supports in the would hold it in good health enough and not in our kitchen upstairs above the bacment the floor is slumped. my brothers room door won't shut now because of it and the grout line is cracking what can I do? And how would I find someone to horizontal out the house?
Answers:    You will have to find a contractor who knows what to do, probably starting by asking people who list house leveling (which usually involves the outside of the house, so ask a lot of questions) Doing a job as be left at your place is nasty and you may find that the with the sole purpose solution is to put a post in the middle of the basement and encase it decoratively.
When you find someone, ask to chitchat to other customers with similar work because this involves being contained by your house and making changes that need to be tidily done and durable.
Put the supports back ! doh.

Or replace them with RSJ/girder wall to wall. A pious builder will advise.
