What affects the cost of mold remediation

The cost of a mold remediation job depends on the size of the affected area, what has to be removed, and — most important — how the moisture source will be fixed. We do not publish job prices here. Compare written scopes, not a single number.

Factors that usually change the quote

  • The size of the area that will be contained and cleaned, and whether building materials have to come out
  • How the moisture source will be found and repaired (a leak, a wet crawl space, humidity, or something else)
  • Whether testing before or after the work is included, and whether a different company does that testing
  • Drying equipment, containment and cleanup of the work area
  • Licensing or registration, if your state or city requires it for this kind of work

A quote that only covers cleaning visible growth, without a plan for the moisture, is incomplete. Ask for a written scope and a description of how the job will be checked when it is done. This page is not medical advice; for health questions, talk to a medical professional.

When you are ready to talk to companies, pick a city page for listed mold remediation contractors in your area, or start with how to hire and permits and local rules.
