The homeowners of this two-story penthouse reached out to us because they had a water leak on their first-level bedroom ceiling that they did not know where the water was coming from. After two days of diligently doing tests it was determined that the leak is likely coming from the patio of the next-door neighbor. This is kind of a long video (the reason behind making the video was to show our clients that live abroad) however, if you enjoy water leak mysteries, you might enjoy this video.
