The unit downstairs complained about a water leak and there is mold on their ceiling. Two people from Trademark came. They cut a hole from the ceiling downstairs. Then one person was running water from my bathtub/shower. They were able to find the source of the leak, water is penetrating from the cracked grout. They told me how to repair the They also pointed out a few other things that will cause water leak in the future.
Only minor thing is that they charged me from 8-10:30 but they arrived at 9:30. Taking 1.5 hours to get to my place is a bit surprising. But I am happy with their services.
