i have a terraced victorian house. the floor boards are pitch pine, about 120 yrs old. the floors either side of the walls that seperate the hallway and the reception rooms is very unlevel. i would like to take the boards up and level the joits. the main problem is that the stud walls? and central collum seem to be sitting directly on the floorboards and there is a joist either side of them. they are not underpinned! i do not want to remove the walls. i was thinking of simply laying a new floor on top? expensive? or to take up ther floor boards and level the joits as directed! ime not quite sure what to do with the joists that the waals are sitting on?
regards gary :x
