While DIY mold testing kits are available, they have limitations compared to professional services. DIY kits may provide false negatives or positives, leading to inaccurate results and ineffective remediation. Professional mold testing companies offer expertise, precision, and comprehensive analysis. Though DIY kits may seem more cost-effective initially, the potential for errors can result in higher remediation costs later. Investing in professional mold testing ensures accurate results and proper mitigation strategies.
