Do I need to hire a mould remediation/removal expert to remove mould, or can I do it myself?

Mould is very tricky—and when attempting to remove it yourself, you can disrupt it and make it worse. A professional mould remediation company is able to remove it correctly, adhering to the IICRC mould removal guidelines for proper mould remediation. They will also be able to apply measures to prevent regrowth.
