How to Prepare for Your Mold & Air Quality Inspection

Preparing your home before a mold inspection or indoor air quality evaluation helps us assess conditions as they normally exist. Following these simple guidelines improves the reliability of visual observations, moisture measurements, thermal imaging, and any laboratory sampling that may be recommended.

Because Charleston's climate is naturally humid, maintaining normal indoor conditions before the inspection helps us better evaluate moisture-related concerns.

These recommendations apply to most mold inspections, indoor air quality evaluations, moisture investigations, and sampling appointments. If your inspection requires different preparation, we'll let you know in advance.

• Keep windows and exterior doors closed for 12–24 hours before the inspection whenever possible. 
• Operate your HVAC system normally.
• Avoid cleaning, cooking, or activities that create heat, moisture, smoke, or airborne particles. 
• Avoid running humidifiers, dehumidifiers, air purifiers, ozone generators, or ionizers unless discussed beforehand. 
• Make sure important areas of the home are accessible. 

Keep windows and exterior doors closed as much as practical for 12–24 hours before your appointment. Normal entry and exit is perfectly fine—just avoid leaving doors or windows open for extended periods.

Continue using your heating or air conditioning system as you normally would. We want to evaluate your home under typical living conditions rather than temporary conditions created specifically for the inspection.

The following activities can temporarily change indoor conditions and may affect inspection findings or laboratory samples.

Please avoid:

• Cooking that produces excessive heat, steam, smoke, or grease shortly before the appointment 
• Showering or taking hot baths immediately before we arrive 
• Dusting, sweeping, mopping, or vacuuming for at least 24 hours beforehand 
• Burning candles or incense 
• Smoking indoors 
• Using strong fragrances, air fresheners, or cleaning chemicals 
• Running humidifiers, dehumidifiers, air purifiers, ozone generators, or ionizers unless discussed in advance 

These activities can temporarily alter moisture levels or airborne particles, making inspection findings less representative of everyday conditions.
 

If applicable, please provide access to:

• HVAC equipment and thermostats 
• Attic access 
• Crawlspace access 
• Under sinks and around plumbing fixtures 
• Utility rooms and laundry areas 
• Water heater and mechanical equipment 
• Areas with odors, staining, humidity concerns, or previous leaks 

If furniture or stored items are blocking a suspected problem area, moving them beforehand is greatly appreciated.

Please let us know if any of the following apply:

• Current or previous roof leaks 
• Plumbing leaks or overflows 
• Flooding or exterior water intrusion 
• Previous mold remediation 
• Persistent musty odors 
• Visible staining or moisture 
• Recent renovations or repairs 
• HVAC repairs or replacement 

The more information you can provide, the better we can understand the property's history and focus our inspection.

If a leak recently occurred, avoid aggressively drying or cleaning the affected area immediately beforehand unless necessary to prevent additional damage. Observing current conditions often provides valuable information during the inspection.

If possible, keep the HVAC system operating at normal settings before the inspection. Homes that have been shut down for extended periods may not accurately represent normal living conditions.

Recent rainfall can provide valuable information about moisture intrusion. Please let us know if the property has experienced heavy rain shortly before the appointment.

If your inspection is being performed after mold remediation, follow any instructions provided by your remediation contractor or laboratory. Post-remediation evaluations may include a visual inspection and, when appropriate, additional sampling to help verify conditions.

Every inspection begins with a discussion of your concerns, followed by a detailed visual inspection, moisture measurements, and thermal imaging when appropriate. 

If laboratory sampling is recommended, we'll explain why it's appropriate, what information it may provide, and answer any questions before collecting samples.

Our goal is to recommend testing only when it provides meaningful information that can help answer your questions or guide next steps.
 

Normal meal preparation earlier in the day is fine, but avoid cooking that produces significant heat, steam, smoke, or grease shortly before your appointment.

Yes. Continue operating your HVAC system as you normally would before the inspection.

It's best to avoid vacuuming, sweeping, or dusting for at least 24 hours beforehand, as these activities can temporarily affect airborne particles.

That's perfectly fine. Simply avoid leaving windows or exterior doors open for extended periods before the inspection.

Temporary changes to the indoor environment can influence:

• Moisture conditions 
• Airborne particle levels 
• Laboratory sampling results 
• Overall inspection findings 

Following these recommendations helps us provide the most accurate inspection findings possible.
