Mold Sampling Prep

Preparing Your Home for a Mold Inspection

Keeping your home closed up before a mold inspection is important. Doors and windows should remain shut so indoor air isn’t diluted by outside air, allowing any mold spores present to be detected more accurately during testing.

Because your HVAC system circulates air throughout the home, it should be operating under normal conditions during a mold inspection. If the system has been off for an extended period, reduced air movement can cause mold spore levels to appear higher than they typically would during everyday living conditions.

Air purifiers and dehumidifiers can reduce airborne particles and moisture, which may interfere with mold testing accuracy. Humidifiers can add excess moisture to the air, potentially affecting results as well. For the most reliable readings, these devices should be turned off at least 24 hours prior to your mold inspection.

Mold is usually linked to a moisture source, often from a plumbing leak. Bathing or showering adds excess moisture to the home, which can make it more difficult to identify the true source of moisture if mold is found during the inspection.

Your mold inspector will need clear access to all areas of the home, so any obstacles or clutter should be removed ahead of time. Please also empty cabinets under sinks and other locations where mold may commonly be found.
