What's the average cost of mold remediation?

The average cost of mold remediation depends on the size of the affected area, the type of materials involved, and whether there are complications like HVAC contamination. Small, localized jobs can cost relatively little, while mold spread across multiple rooms, walls, or ceiling cavities can become more expensive. Costs typically include inspection, containment, removal of contaminated materials, cleaning, air filtration, and possibly post-remediation testing. Access issues, such as tight crawlspaces or attics, can increase labor and equipment needs. Because mold is often tied to underlying moisture problems, you may also need to budget for repairs to plumbing, roofing, or other sources of water intrusion in addition to remediation.
