Arrived and found moisture in the kid’s closet wall/ carpet. The closet shared a wall with the bathroom and was on the opposite side of the shower valve. I opened up the wall in the closet and and discovered the water was spilling out of the tub/shower and flowing into the closet after pooling up on the tile in the bathroom. I checked the meter and did not locate any fresh water leaks. There was no moisture on the ceiling under the shower which showed there was no drain leak. Customer was advised to be more careful with fully closing he shower curtain. I also located mold in the closet. I recommend that we complete mitigation and proper dry down of carpets and wall. Customer declined any further work and said he would address the issues on his own. Customer was not charged for any work completed
