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 Answers

You notice musty odors, visible staining, or unexplained health symptoms, but without sampling data you cannot confirm what is present or how serious the situation is.

Mold Testing vs. Mold Assessment

Mold Testing: What ESG Does

Mold testing collects and analyzes samples to determine whether mold is present and what types exist. It provides objective, lab-verified data about your indoor environment.

  • Identifies mold species and spore concentrations
  • Confirms or rules out visible suspect growth
  • Provides documentation for real estate, insurance, or legal purposes
  • Delivers an independent, unbiased written report

When You May Need a Full Assessment

If the source of moisture or the full extent of contamination must be determined, 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 exactly does mold testing measure?

Mold testing collects air and 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.

Does ESG perform mold remediation?

No, and that is intentional. ESG is a testing and consulting firm only. We never perform remediation work, which means our testing results are completely unbiased. We have no financial incentive to find a problem or to exaggerate its severity. Our role is to give you accurate data and clear guidance.

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 assessment and payment. Your report includes laboratory results, expert interpretation of what the findings mean, and recommendations for next steps if any action is needed.

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 identifies whether mold is elevated; a Mold Assessment identifies why.

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

Yes. ESG's written reports and laboratory documentation are built to stand up to scrutiny in real estate transactions, insurance claims, and legal proceedings. Because ESG is an independent testing firm with no remediation interests, our reports carry credibility as unbiased, third-party environmental data.
