Upon arrival customer explained that there was mold on wall of closet behind water heater. We looked in closet and found that everything is dry but has lots of growth. The customer will have restoration company in to remove the sheetrock. Customer also made me aware that she was having issues with two shower valves. After investigating, we found that the one in the guest bathroom upstairs would convert to shower and would not get cold. The tub/shower in Jack and Jill bathroom would not convert to shower. I gave customer 3 options and she stated that she will probably go with option 3 and is going to wait until sheetrock is removed and if any plumbing repair is needed have it all done at one time.
