This Home Inspector Needs Training Wheels
This visible drywall patch is the reason why this homeowner needed us to come out and inspect. Their home is for sale and a home inspector had identified this spot on the wall that’s being wet. It is not wet, the homeowner used a metal patch as part of his drywall repair. Just from the appearance of the patch I could tell that he used one of the metal plate patches. If you use a non-penetrating moisture meter and set it on a metal surface it will give you a false positive and may lead you to think the materials are wet if you don’t know better.
