This is because the mold should be just on the surface and shouldn't have penetrated into the drywall itself.

Mold and mildew in closets are common problems at the coast because of moisture and stagnant air, but building damage from water penetration is just as common.

The first thing I would look at is the penetrations.

Roof leaks and windows leak moisture that runs down and damages floor areas by the windows.

I've replaced a few of them due to damage caused by the original trim carpenter nailing trim and the nail penetrating the balance (it took some time for the damage to kill the balance).

I imagine if you started looking over the home you'd have to repair the roof, and even though I could not see any damage, there may be some issues with mold or otherwise owing to the existence of moisture from the operation.

I guess because we did not want to penetrate the wood.

The most pressing include a leaking main water pipe in the crawlspace, several dead outlets, non-grounded outlets and non covered outlets, a loose shower liner/insert that has caused mold and moisture damage on the bathroom sheetrock (there is no vent/fan in there), and the carport and porch roof are leaking.

This is important because the depth of frost penetration may or may not be an item of concern when determining the repair type (depth of repair, etc).

Hollow core doors can hold water and retain moisture, get rid of them.These issues were found with flooding along the White River in Branson and the Mississippi floods, fresh water, but also contaimnated water.
