Water staining on dining room ceiling. Estimate includes cutting Sheetrock to investigate the source. We do not repair Sheetrock. Also includes installing a customer supplied widespread faucet in the main floor half bath. We cut Sheetrock in dining room ceiling and ran water in tub and shower above for 40 minutes. We also filled and drained the tub. We found no leaks and no moisture in the ceiling. We did find that master shower trim was loose and the handle was hard to turn. We replaced the master shower’s moen cartridge, and properly secured and caulked the trim plate to ensure no water could leak behind trim. We also installed a customer supplied delta widespread lavatory faucet in the half bath.
