Testing
Do I need a mold inspection before buying a house in Gettysburg?
You need a home inspection that actually lingers on the basement, attic, fans, and downspouts. Add a mold-focused visit if that inspection finds staining, elevated moisture, a harsh smell, or a freshly painted cellar with a roaring dehumidifier.
Old houses here almost always have a moisture story. The goal is to know whether it is a downspout or a wall, before you waive the chance to find out. A written remediation quote beats a guessed credit.
