Exhaust fan rerouting — the most common correction we make on Lakeland, FL attic mold jobs — requires matching the fan duct diameter to the fan's rated CFM, using insulated flex duct (not bare uninsulated duct), and terminating at a properly sized exterior cap. Done wrong, the fan creates a condensation point inside the duct and moves the moisture source rather than eliminating it. Done right, it removes 30–80 pints of moisture-laden air from the bathroom per hour depending on bath size.

The cause determines which corrections will work. Treating sheathing without identifying the cause means treating the symptom without preventing recurrence.
From panel-by-panel sheathing assessment through fan rerouting, ventilation NFA correction, and post-clearance verification — the full attic mold scope for Lakeland, FL properties.
