I have a 100 year old house with a room with old outdated ceiling tiles that I want to disappear. I don't know if the tiles are glued or stapled on but there are furring strips that run the length of the room that the tiles are adhered to. The ceiling behind this is a plaster ceiling. Can I just put drywall over everything or do I need to remove the ceiling tiles first? The tile have been there for at least 50 years and I don't know what they may contain. I also want to keep the mess to a minimum. Can I reuse the furring strips? The furring strips are 3in. x 3/4in in size.
What is the best way to handle this?
