Mold in homes built before about 1940
I Like To Fix
Pre-war construction — galvanized supply, cast iron drains, cloth-wrapped wiring, ungrounded circuits.
What follows is every mold problem we cover that concentrates in this era of construction. Age does not mean worse — it means a different set of failures.
- Musty smell with nothing visible
- Crawlspace with bare soil
- Growth returning after cleaning
- Black staining behind furniture on an exterior wall
- Testing offered before any inspection
- Old flood line on basement or cellar walls
- Plaster bubbling near a chimney
- No bathroom exhaust fan
- Insurance denying the claim
