A good property inspector is always on the lookout for telltale signs.
A door that rubs its frame… Exposed electrical wires… Loose handrails… Missing smoke detectors, etc.
High water marks under a house; usually gets people’s attention.
In the photo, the bottom of a heating/cooling duct in the crawlspace is rusted in a straight line… A telltale sign that the duct sat in water approximately 6-8” deep.
This isn’t good. Who knows what grows inside a duct when water intrudes. Can’t be healthy.
High water marks or silt marks can occur when:
-There are no installed roof gutters
-Downspouts discharge water next to the foundation
-There’s a negative grade (the yard slopes towards the house)
-A surface drainage grate becomes clogged during a heavy rain
-A water supply pipe leaks or breaks
The source of the water accumulation under a house should be identified and steps taken to minimize water intrusion.
