My house is about 118 years old and I can tell from all around the house that there seems to be a sagging on my floors in one specific area. This sagging is obvious in the first and second floor. Now I just want to make sure that this is normal and if it needs to be fixed who should i call and for what price.
The sagging goes down to about a max of 2 inches and the floorboard feel loose throughout the entire second floor because of it. Any help would be greatly appreciated!
