The published range

Angi, How Much Does Mold Remediation Cost? prints a range of $500–$1,000 for mold remediation in a bathroom location. The same guide gives $2,369 as the national average for a mold job of any kind and $1,223–$3,757 as the typical span, so even the top of the bathroom range is $1,369 below that average.

Ranked by the midpoint of each published range ($750 here), the bathroom comes 7th of the 7 locations in the guide. Nothing in the guide costs less. The high end is 2 times the low end, a narrow spread, so quotes outside it deserve a question about scope.

The guide also prints a per-square-foot rate of $10 to $25. Arithmetic on that rate, not a published figure: at the EPA's 10 sq ft homeowner line the rate works out to $100–$250, and at the 100 sq ft line where EPA moves from limited to full containment it is $1,000–$2,500. Read the other way, the bathroom range lines up with roughly 20 to 100 sq ft of affected surface at that rate, which stays inside EPA's medium category.

Bathroom growth tends to sit on visible surfaces around tubs, showers and exhaust fans, which is what keeps it a contained location in the guide.

Mold follows water. EPA's guidance is “It is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth.” (U.S. EPA, A Brief Guide to Mold, Moisture and Your Home) The water damage guide prices the related bathroom fixture work at $140–$800, overlapping the mold range.

Size, testing and licensing

EPA sorts mold cleanup by the area affected: small under 10 sq ft, medium from 10 to 100 sq ft with limited containment, large above 100 sq ft with full containment. On testing, EPA says “In most cases, if visible mold growth is present, sampling is unnecessary.” (U.S. EPA, A Brief Guide to Mold, Moisture and Your Home). In the states that license mold work, a hired company needs a license above a set size or value; see mold licensing by state.
