Indoor Environmental Systems Inc

Indoor Environmental Systems Inc operates from Cary, North Carolina, serving the greater Triangle area including Chapel Hill and Alamance County. Led by Steve McLeod, who brings more than 30 years of specialized experience in indoor environments, the company focuses on mold assessment, indoor air quality testing, and remediation protocol development. The firm holds double board certification as an Indoor Environmentalist and Environmental Professional through the International Society of Environmentally Acquired Illness, with advanced training from Mosaic Diagnostics. With a 4.8-star rating drawn from 30 client reviews, the team works exclusively with homeowners experiencing environmental health concerns, from suspected mold exposure to sick building syndrome.

What distinguishes this contractor is their protocol-driven methodology rather than traditional remediation work. Rather than performing the actual cleanup, Indoor Environmental Systems develops comprehensive remediation strategies and connects clients with qualified local contractors who execute the plans. Their process encompasses detailed assessment and testing, custom remediation protocols, quality control oversight, and maintenance planning. The company also offers a curated selection of healthy home products including HEPA air filters, smart sensors, and eco-friendly cleaning solutions, along with mold training courses for homeowners seeking to understand detection and assessment methods.

Reviewers consistently highlight Steve McLeod's thorough investigative approach. Holli's review describes how Steve identified mold in her HVAC system after another inspector had declared her home problem-free, confirming the discovery during remediation. Michele Nelson's feedback emphasizes the peace of mind gained from working with a team that remains involved throughout the entire remediation process, verifying that contractors complete work to specifications. Beth Whithaus, who had undergone two previous remediations over 12 years, found Steve's methodology more exhaustive than prior experiences, with his multi-location inspection revealing issues other specialists had missed. Each of these clients specifically mentions working with both Steve and Lori, the office coordinator who manages communication and scheduling.
