Published guides anchor mold remediation at roughly $10 to $25 per square foot of affected area, with small contained jobs commonly landing between $500 and $1,500 and whole room or multi room jobs running into the thousands. The spread is honest: a bathroom wall behind a failed pan and a whole AC system with duct growth are both called mold jobs, and they share almost nothing else.
Humble area numbers are anchored the way the published guides anchor them, roughly $10 to $25 per square foot of affected area with small contained jobs commonly between $500 and $1,500, and then they are written by the moisture map: how much material comes out, what the source correction costs beside it, and whether the house's water history, Harvey era or last month's, is part of the scope. The map, not the square foot alone, is the estimate's honest unit.
What moves the number, in the order it usually matters: how much material has to come out (drywall and insulation are cheap to remove and not free to replace), containment complexity in an occupied home, whether the moisture source needs a trade repair alongside, and verification testing for a real estate or insurance file.
Florida adds one line item northern states skip: the assessor and the remediator are separate licensed roles, and on larger jobs the assessment and the post remediation verification are their own costs. Anyone quoting a firm total by phone, without a moisture map, is inventing the number.
