Diagnostic testing can reveal hidden problems, even in homes that look clean and well-kept. These tests help guide decisions on whether remediation is necessary—or whether to walk away.

Common options include:

• ERMI or HERTSMI-2 dust testing: Evaluates mold DNA levels from settled dust.
• VOC sampling: Identifies chemical pollutants from building materials or furnishings.
• Formaldehyde and aldehyde testing: Useful for homes with new finishes or pressed wood.
• Radon testing: Recommended for homes with basements or in radon-prone regions.
• EMF evaluations: For those with sensitivity or proximity concerns.

Work with a professional who can explain the results and relate them to your specific health conditions. Some tests can be performed DIY using Swiffer dust cloths, but professional interpretation is essential.
