Try doing a search for chipboard flooring and most of the results will come back with “how do I stop my chipboard floor squeeking”, “my squeeking chipboard floor is driving me to the arms of another man it’s so annoying”, “I’m about to run off and become a beaver if nobody can help stop my chipboard floor squeeking”.
Any reason you are replacing the floorboards? Damaged, woodword, bored?
Do you have a budget? How big is the landing…..?
