While corrective action for an uneven floor with elevated moisture, loose toilet and leakage is a no brainer, what corrective action would one suggest for uneven floor, elevated moisture but new vinyl, firm toilet attachment and no signs of leakage i.e. they recently replaced the floor covering and wax ring but not the moisture deteriorated underlayment? And what about the same senario except with no elevated moisture just dry swollen underlayment? Thanks, Chris
