When the Stain Outlasts the Growth
Mold frequently leaves permanent discoloration in wood after the organism itself is removed, particularly on attic sheathing, floor joists, subfloor and exposed framing. The staining is not active growth and is not a health hazard, but it fails visual inspections, alarms buyers and inspectors during a real estate transaction, and can stall a sale or a loan. Aesthetic remediation resolves the appearance issue after the actual remediation is complete.
