Indoor Air Quality Testing

Professional mold testing with independent results you can trust

ESG collects targeted air and/or surface samples, sends them to accredited third-party labs, and delivers a written report summarizing the results. Evaluation stays separate from corrective work. We test. We never remediate.

From uncertainty to answers

Mold spores exist everywhere. The question is whether indoor levels are elevated and what that means for your building. Testing replaces guesswork with data.

Suspected mold, no data

You notice musty odors or visible staining, but without sampling there is no measurement of what is actually present in the areas of concern.

After ESG Testing

Lab results and a clearer picture

You receive a written report identifying the mold types and spore concentrations found in the samples collected, with the indoor vs outdoor comparison when an outdoor sample is taken, and a plain-English summary of what the results show.

What a mold testing visit can include

ESG collects the samples your situation calls for using calibrated equipment, sends them to accredited third-party laboratories, and delivers a clear written summary of the results. The sampling scope, air, surface, or both, is agreed with you before the visit.

Air sampling with calibrated pump and spore trap cassettes, measuring mold spore concentrations in indoor air, when air sampling is part of the agreed scope
Outdoor baseline air sample for indoor vs outdoor mold comparison whenever indoor air samples are collected
Surface sampling via sterile swabs or tape lifts on visible suspect growth, when surface sampling is part of the agreed scope
Accredited third-party laboratory analysis identifying mold types and spore concentrations in the samples collected
Written report delivered within 3 to 7 business days, with the laboratory results and a summary of what they show
Expert consultation with an ESG professional to review your report and discuss results

Why ESG

Science-based testing with no remediation conflict

Environmental Solutions Group has been providing independent environmental testing and consulting for 23+ years, since 2002. Our mold testing is performed by ESG's own field staff, not by contractors who profit from cleanup work.

ESG is an independent third-party testing and consulting company and does not perform remediation. This separation helps reduce financial conflicts between evaluation and corrective work. What you get is the accredited laboratory data and a clear explanation of what it shows.

Our written reports explain what the numbers mean, and an ESG professional is available to talk through the results after your report is delivered.

Lab analysis

Samples are shipped to accredited third-party laboratories. Results identify the mold types and spore concentrations in each sample and, when an outdoor sample is collected, the indoor vs outdoor comparison that guides interpretation.

Mold testing vs. mold assessment

Mold testing: what ESG does

Mold testing collects and analyzes samples to identify what is present in those samples and at what levels. It provides objective laboratory data about the locations sampled at the time of collection.

  • Identifies mold species and spore concentrations
  • Shows what surface samples find on visible suspect growth
  • Provides documentation for real estate, insurance, or legal purposes
  • Delivers an independent, third-party written report

When you may need a full assessment

If the moisture source or the likely extent of contamination needs to be investigated, a Mold Assessment goes further, using moisture meters, thermal imaging, and detailed building investigation.

  • Mold testing alone does not locate the moisture source
  • Does not evaluate how far hidden contamination may have spread
  • Does not include remediation protocol development
  • If ESG sees signs of moisture during testing, we may recommend a full assessment

Mold testing: frequently asked questions

What does mold testing measure?

Mold testing collects air and/or surface samples that are analyzed by accredited laboratories to identify what types of mold are present and their concentrations. Air samples measure spores per cubic meter of air. Comparing indoor results to an outdoor baseline helps determine whether indoor amplification is occurring. Each sample is a point-in-time snapshot of the location sampled. ESG evaluates and documents environmental conditions. ESG does not diagnose medical conditions or determine whether a building condition caused symptoms. Results may be shared with a qualified healthcare provider.

Does ESG perform mold remediation?

No, and that is intentional. ESG is an independent third-party testing and consulting company and does not perform remediation. This separation helps reduce financial conflicts between evaluation and corrective work. Our role is to provide the data and explain what it shows.

When do I need mold testing vs. a full mold assessment?

Mold testing answers: "Is mold present, and what types?" A full Mold Assessment goes further, using moisture meters, thermal imaging, and building investigation to answer: "Where is the moisture coming from, and how extensive is the problem?" If ESG detects signs of moisture during testing, we may recommend a full assessment.

How long does it take to receive my report?

Reports are typically delivered within 3 to 7 business days after the on-site sampling visit and payment. Your report includes laboratory results and a clear summary of what the findings mean.

What are common sources of indoor mold growth?

Mold grows wherever moisture is present. Common sources include roof or plumbing leaks, past flooding or water damage, high indoor humidity, poor ventilation, and condensation inside walls, attics, or crawlspaces. Testing indicates whether spore levels in the samples are elevated; a Mold Assessment investigates why.

Can mold testing be used for real estate or legal purposes?

Yes. ESG's written reports and laboratory documentation are prepared to a professional standard commonly relied on in real estate transactions, insurance claims, and legal matters. Because ESG is an independent third-party testing company that does not perform remediation, the reports come from a party with no stake in the corrective work. Findings apply to the locations, measurements, and samples evaluated at the time of service.
