Hello,
Advice sought by novice d-i-y'ers.....
We own an 18th Century cottage., the floorboards in our dining room are generally uneven with a range of approximately 5cm in a 15sq metre area. The floor is otherwise sound and is over a 6ft void.
What would the best method be to provide a level surface on which to lay a hardwood floor over the top?
Thanks in advance
