Upon entering the unit, owner of property stated the tenant had a handyman came to change the Moen shower valve. Valve is leaking everywhere into the kitchen and into the bathroom. I provided an estimate to replace Moen shower cartridge and shower valve diverter. Customer was getting ready to sign and agreed to do the work, but then said that we had to replace the drywall that we cut out. I called on the recorded line to give him the option to go through the tile with the repair plate and he said he was going to have to call us back because we should be responsible for the drywall if we cut it out
