Hi all, My floor laminates are newly installed on cement screeded floor. When we walk on them, it creaks almost everywhere in the rooms. The ID said it will take time and usage of the floors for the sound to go away. I haven't been able to find anybody asking about this, so I'm wondering if this is such a well accepted fact that there's no need to ask about it, or is this a rare defect? Haha. Any help appreciated, thanks in advance!
