Water damage in bedroom closet

we have some water damage on the floor and lower wall in the master bedroom closet in our townhouse. We had a similar situation a few months back. Dried it, cleaned it, and all was ok for about 3 months. Not sure if it is something caused by us or our neighbors. Our neighbors house has been vacant for a while and major renovations have been done to it during that time.

Who is the best person to call? A plumber? Anyone have a recommendation?

Thanks for your help...

 

Does that part of the wall face a neighbor townhouse? Or is it on the backside of the master bath? You may have a water pipe there connecting to your master bath... but you will have to do some guessing. Since it is in a closet, you could cut the wall to explore the area and try to confirm what, if any, pipes are there and where they might connect.

Fixing some drywall in a closet is not a big deal.... But if you feel safer, you should just call a plummer.
