Hi there,
My fiancee and I recently purchased a ~20-year-old apartment in the East Coast, and we realize that there are quite a few tiles which sound hollow when they're tapped due to debonding/drying of the adhesive. See photos here uploaded.
We've asked a few contractors to recommend whether or not we should hack and replace the wall and floor tiles in the affected rooms with new ones. So far, we've received mixed messages: some say that it's okay not to change them as long as you don't do any drilling on the affected wall. Other say that you should change them as they could pose a safety risk (popping out and potentially dropping on or tripping someone).
Our question is: What are the pitfalls of leaving hollow tiles as they are?
Thank you very much!
