I have just recently purchased a business that has a large house on the property built in the 20's. Over time due to settling and likely some botched repairs the floor on the second floors slopes pretty badly.
Long story short, I have torn up the carpet and old hardwood which has left me with just the beams. The room slopes drastically from the outside in which is about 3 inches over a span of about 10 feet which is very noticeable. I can not shim up the low side because that will leave a 3 inch step into the room of which the ceilings and doorways are already incredibly low.
I know cutting beams should always be avoided but I was wondering if it would be alright to cut the beams on the tall side (2x8 beams) down roughly 2 inches and then sister new 2x6 beams to them to allow leveling as well as more support?
