Upstairs condo neighbor had an ongoing leak for about two weeks in their bathroom. Not sure what was leaking, but they replaced toilet ring and shower faucets and since then the leak has stopped. This has caused the this damage to my ceiling:
There are only spots visible on the ceiling, but no signs of mold. Can there be mold growing in the ceiling drywall between the floors? Is it a concern? Does the drywall need to be cut out or is it sufficient to remud damaged area, sand and paint?
