The whole of the back of my house was once an enclosed veranda but now is divided into rooms and built on how do I correct the slighty sloping floor.
Thanks Paul:)

How much slope?

Is it from settling or was it the original design?

What type of floor is it,concrete,wood?

can you add to the existing floor height,say with 2X4's cut to make the floor level,then plywood/OSB on top,will the door openings allow for this raise?
