Still planning the hardwood floor installation in my house. Already decided on how I will compensate for the floor sagging. Thanks for all the hints.
Now I have another question.
I am installing tongue and groove solid hardwood and the planks are nalied to the subfloor through the tongue side, which means we have to always start from one end of the room and go up to the other end.
The problem is how we start and finish in rooms where the floor goes through doors? For example, one of the bedrooms has a walk-in closet. If start to install the hardwood on the bedroom and then transition to the closet through the door, on one side I will not be able to nail the planks thorugh the groove. That is, the door is in the middle of the room, therefore the floor will "expand" to both sides of the door. How to proceed in this case? I understand we cannot nail the hardwood planks through the grooves.
Thanks much in advance again.
