336-373-1538ESG is a Greensboro-based environmental testing company dedicated to one thing: giving you an honest picture of your indoor environment, free from the conflicts of interest that come when the same company tests and remediates.
The most important thing you should know about ESG is this: we only test. We do not offer remediation services, and we never will. That single policy is the foundation of everything we do.
When a company both tests and fixes environmental problems, there is an inherent financial incentive to find problems, and to find bigger ones. That conflict of interest can compromise the objectivity of every report they write.
ESG removes that conflict entirely. Our only job is to test accurately and report honestly. Whether your results are clean or concerning, you get the truth, because we have nothing to gain from telling you otherwise.
"Our reports are always honest and objective. We do not profit from the results, no matter what they are."

When ESG was founded in Greensboro, NC, the Triad region had no shortage of companies that would come out to test your home or building, but nearly all of them also sold remediation services. True independence was rare.
ESG was built to fill that gap: a firm whose only product is accurate, defensible, science-based testing. Over 23+ years we've grown into one of the region's most trusted names in indoor environmental quality, serving residential and commercial clients across North Carolina, Virginia, and Tennessee.
Our methodology follows published, peer-reviewed protocols. Our results are reproducible, and our documentation is built to stand up to scrutiny.
From mold and air quality to water, lead, and more, we provide comprehensive independent testing for homes and commercial buildings.
