About Us

At 4 Corners Environmental, we take a comprehensive, science-based approach to creating safer, healthier spaces. Whether you’re concerned about mold, air quality, or other environmental hazards, our testing and inspection services deliver the clarity you need to make informed decisions.

We are NORMI-trained and proud members of ASHRAE and IAQA, bringing industry-leading expertise to every home. Our specialized training allows us to serve even highly sensitized individuals, and our state-of-the-art equipment sets us apart from other companies in the region.

While Tennessee is not a regulated state for mold testing, we operate as though it is, holding ourselves to the highest industry standards. This means no shortcuts, no conflicts of interest, and no compromises — just accurate, ethical, and actionable results you can trust.

Founded and owned by Barry Mankin, 4 Corners Environmental is the trusted partner for homeowners, real estate agents, property managers and mold remediators across Middle Tennessee. From the first phone call to the final report, we’re committed to providing clear answers and practical solutions — never fear or confusion — so you can breathe easier and live better.
