Providing you with peace of mind and confidence in your purchase


The Institute for Environmental Assessment, Inc. (IEA) has extensive experience providing environmental due diligence services. Due diligence is known as “the care that a reasonable person exercises under the circumstances to avoid harm to other persons or their property.” In matters related to indoor air quality requirements, it can refer to the identification and resolution of mold and water challenges prior to conducting a property transfer.

Mold and water damage can lead to costly remediation and renovations for the buyer if discovered after the purchase. The extent of problems arising from mold and water intrusion that doesn’t meet indoor air quality requirements is not always obvious. It is therefore important to work with experienced environmental consultants to protect the value of the intended property acquisition – in short, exercising due diligence.

Indoor air quality due diligence for new tenants or buyers


A due diligence walkthrough includes an on-site visit and facility inspection to document obvious indoor air quality concern issues such as water-impacted building materials and mold. It may also include interviews with individuals who may know about mold, mildew, and water damage events in the past. A written report outlining findings and recommendations is included.

For additional peace of mind, IEA offers several cost-effective sampling strategies that can be added to the basic due diligence walkthrough:

  • Sampling to determine the extent of fungal growth
  • Assessment of the HVAC system
