A Complete Resource Library, Organized by Topic

South Florida's humidity, hurricane-driven water intrusion, and CBS/stucco construction create mold risks that look different from the rest of the country. These resources are organized into six categories so you can go straight to what you need: mold & inspection guides, laboratory information, building science, checklists, research articles, and the fundamentals in between.

Worth Investigating

Indoor counts notably higher than outdoors. Professional inspection recommended.

Action Recommended

Stachybotrys, Chaetomium, or significantly elevated counts detected. In-person inspection advised.

Hidden Moisture & Negative-Pressure Ductwork

Ductwork that runs at negative pressure relative to the surrounding attic or wall cavity can quietly pull humid, unconditioned air into spaces where it condenses on cooler surfaces — creating hidden mold growth long before any odor or stain reaches a visible interior surface. This article walks through a real Home Enviro field investigation of negative-pressure ductwork, explaining how differential pressure testing, thermal imaging, and moisture meter readings were used to trace a hidden moisture problem back to its source, and what the findings mean for South Florida homes with attic-run HVAC systems.

HVAC Plenum Tape & Mold Contamination

Foil tape and mastic at plenum and duct joints degrade over time in Florida's heat and humidity, and once a seam fails, the plenum can become a growth surface in its own right rather than just a leak point. This article documents a real case where deteriorating plenum tape led to microbial contamination inside the HVAC supply system, covering how the failure was identified, why plenum-level contamination is different from ordinary duct dust, and what remediation and prevention look like for similar systems.
