$1,350 to $4,900

Mold remediation cost has an overall typical figure of $2,350, within a sourced range of $1,350 to $4,900. The ranges on this page come from two sources, Angi and HomeGuide. The area affected drives the price, from a bathroom to a whole house. This page covers cost only. Use the figure as a starting budget, not a quote.

By area

Each row combines one range from each of the two sources. For the basement and attic, HomeGuide gives partial and full figures, and this page uses the partial figures. Angi lists testing separately; HomeGuide does not say whether testing is included.

Rates, testing and related work

Testing, inspection and drywall repair can be priced separately. Angi's page gives conflicting figures for testing and for drywall repair, and both are shown. These single-source figures keep their original amounts and wording.

Rates

These rates are shown for context. They are not added, because the area ranges are treated as whole-job prices.

The low and high are the medians of the published bounds. For two sources, the median is the mean of the pair. Typical is the median of the source midpoints. Derived figures round to twenty-five-dollar steps below a thousand dollars and fifty-dollar steps at or above it, with exact halves rounded up. The estimator selects its base bounds, adds applicable extras in full and rounds the final totals.
