Post-war and mid-century — copper supply, aging cast iron stacks, 60 to 100 amp panels, first-generation central air.

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.

• Growth around supply registers
• Damp along the bottom of a slab wall
• Bathroom fan venting into the attic
• Humidity above sixty percent indoors
• Water heater or AC pan with standing water
• Carpet that stayed wet
• Contractor quoting whole-house remediation from a photo
• Discoloration on the ceiling under a bathroom
• Crawlspace vents open year-round

Back to Mold.
