I am looking to buy an old house that was built in the early 1900's. The upstairs floor in only one room slopes. A wall was taken down two combine two small rooms into one big room. The sloping in concerning, but i love the rest of the house. Any ideas as to how big of a project leveling this floor might be? The floor in a one spot also squeaks. Any help would be appreciated.
A house that old will have a field stone foundation, which means this slope is probably caused by the entire house settling.
Jacking up the settled wall is a big job, involving several piers and serious structure, and will have ramifications throughout the house with cracking plaster and out-of-plumb doors.
This is probably not cost effective for a house of that age unless it has historical value.
I would say deal with the slope, or find a different house.
