What a Professional Mold Inspection Report Should Include

By Tom Duff — Certified Mold Inspector|January 5, 2026|3 min read

Not all mold inspection reports are created equal. Here's exactly what a thorough, professional report should contain - and the red flags that indicate an incomplete or inadequate inspection.

A mold inspection report is the primary deliverable from a mold inspection. It documents what was found, where it was found, what the laboratory results showed, and what should be done about it. The quality of this report determines how useful the inspection actually is.

Unfortunately, not all mold inspection reports are created equal. Some are thorough, specific, and actionable. Others are vague template documents that tell you little more than whether mold was or was not found. Knowing what a good report should contain helps you evaluate whether you received a quality inspection.

10 Things Every Professional Mold Report Should Include

Inspector Credentials and Certifications

The report should identify who conducted the inspection and their relevant credentials. In Pennsylvania, mold inspectors are not licensed by the state, but professional certifications such as CMI (Certified Mold Inspector), CMC (Certified Microbial Consultant), or CIEC (Council-certified Indoor Environment Consultant) indicate that the inspector has met established professional standards.

Property Information and Inspection Date

The report should clearly identify the property address, the date of the inspection, and the conditions at the time of inspection (temperature, relative humidity, weather). Conditions affect mold testing results, and this information is necessary for proper interpretation.

Scope of the Inspection

The report should clearly describe what was and was not inspected. If the inspector could not access certain areas (locked rooms, inaccessible crawl space, etc.), this should be documented. A report that does not define its scope leaves the reader guessing about what was actually assessed.

Findings with Specific Locations

Every finding should be tied to a specific location in the property. 'Mold found in basement' is not sufficient. A good report specifies: mold found on the north wall of the basement mechanical room, approximately 4 square feet, on the wood framing above the sump pit. Specific locations allow remediation contractors to find and address exactly what was found.

Moisture Meter Readings

Moisture is the root cause of mold. A thorough inspection includes moisture meter readings in areas of concern, and these readings should be documented in the report. Elevated moisture readings without visible mold indicate areas at elevated risk for future mold growth.

Photographs

Every finding should be documented with photographs. Photographs provide visual confirmation of findings, help remediation contractors understand the scope of work, and serve as documentation of pre-remediation conditions. A report without photographs is incomplete.

Laboratory Results

If air or surface sampling was conducted, the actual laboratory results - not just a summary - should be included in the report. Results should include the laboratory name and accreditation, the sampling methodology, and the species-level identification of mold found.

Interpretation of Results

Raw laboratory results mean little without interpretation. The report should explain what the results mean in the context of the specific property. Is an elevated Cladosporium count significant? The answer depends on outdoor levels, the time of year, and the specific conditions at the property. This interpretation is what you are paying a professional for.

Identified Moisture Sources

Mold grows where moisture is present. A good inspection report identifies the likely moisture source for any mold found. Without addressing the moisture source, remediation will not be permanent. The report should explain what is causing the moisture problem and what needs to be done to fix it.

Recommendations

The report should provide clear, specific recommendations for what to do next. This may include remediation recommendations, moisture control recommendations, and follow-up testing recommendations. Recommendations should be specific enough to be actionable.

10 Red Flags in a Mold Inspection Report

If your mold inspection report has any of these characteristics, you may not have received a thorough inspection. Consider getting a second opinion.

  • No laboratory results included despite sampling
  • Findings without specific locations
  • No photographs
  • No moisture meter readings
  • Recommendations that are vague or non-specific
  • No outdoor control sample comparison
  • Inspector credentials not identified
  • Scope of inspection not defined
  • Results not interpreted in context
  • Report template with minimal property-specific content

A Report You Can Actually Use

The goal of a mold inspection report is not to check a box - it is to give you the information you need to make decisions. Tom's reports are written to be clear, specific, and actionable.

Next step

Still not sure whether you need testing?

Call or text and describe what you're seeing or smelling. If an inspection isn't worth your money, I'll say so — I don't do remediation, so I have no reason to find a problem that isn't there.
