The cost to remove mold from an attic or crawlspace ranges from $2,000 to $6,000, as of September 2015. If the mold spreads to the attic, it is also likely to have spread to other ducts, crawlspaces and walls, making the price higher. If the mold is confined to a single crawlspace, the removal cost ranges from $500 to $4,000.
When hiring a person to inspect the mold, a homeowner must choose a licensed professional because people who are careless risk spreading the mold to other places while inspecting. If a house needs mold removal, the cost of it can sometimes be tax deductible with the IRS.
