I am due to take up a laminate floor in my lounge and replace it with an engineered oak floor. In general, the floor is good and flat apart from one small area, where there is a hump. If you drew a circle around the base of the hump it would measure approx 30 inch diameter max and is around 5mm high.
It is just noticeable with the laminate covering, and I think it will be the same if not more obvious with the engineered floor. It is close to a doorway and the door does catch the top of the hump when its opened.
The only thing I can think of doing to flatten the hump is to take up the floor boards and plane some timber off the top of the joist before re-fitting the boards. The house was built in the early 60`s and obviously has a suspended timber floor.
Am I thinking along the correct lines to remedy this? Can anyone tell me a better way to do this?
