About Steve Major (Principal -- Lakeland Environmental)
(Top Expert on this page)

Expertise
I can answer questions on indoor mold (fungal) infestations, indoor air quality, and indoor moisture problems. This includes mold testing, investigation, and remediation. PLEASE indicate your state or region, so I can provide the best possible answer.

Experience
I have extensive experience in the investigation, testing, and remediation of indoor fungal (mold) infestations, including the design and oversight of remediation projects, hands-on cleaning and removal, and safe work practices. I developed a successful mold remediator training and certification program, and have trained many mold workers and remediation supervisors in proper techniques. I have a strong knowledge of the ways in which moisture and airlow patterns in buildings can affect fungal growth and air quality.

Education/Credentials
BS Cornell University. IAQA Certified Mold Remediator. 40-hour HAZWOPER certification. NYS Department of Health Certified Training Director.
