2nd floor needs leveling
I'm new to the site, so I apologize if I'm over lapping a topic or writing in the wrong area.
We are just waiting for a closing date on our first house which is an 1852 fixer upper ( I know great idea for a first home!)
At some point an extension was built, we think walls were built over an old staircase to the basement without adequate support. Over the years the floors have sloped to the left to the point where now there is a 5 degree angle from the center of the bedroom to the left side of the room.
My question is: How do I level the floors on the second floor? Should I just put up support beams in the basement to make it secure and then fake the level floor using plywood of something?
I'm going to be asking lots of questions over the next few months, my dad always says " there's no such thing as a stupid question", I have a feeling some people may disagree once they see some of mine!
