Exhaust fan rerouting — the most common correction we make on Mullica Hill, NJ 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.

Sapstain vs. active mold, seasonal moisture pattern, fan CFM calculation, panel-by-panel structural assessment — these are the distinctions that produce appropriate scope.
Every scope is written after we've assessed the seasonal pattern, measured MC% on all panels, and audited every exhaust fan termination.
