The cost of sampling will depend on many factors, such as the number and types of samples collected, the method of laboratory analysis to be used, the type of report needed, and the location of the site. Typical mold inspections average between $800 and $1500, and may or may not include remediation maps or thermography. Some mold inspectors take commissions of up to 10% from the contractor for referrals… who do you think pays for that.
