Indoor Air Quality Assessment

ESG's Indoor Air Quality (IAQ) investigations are conducted following the EPA's recommendations for indoor air quality studies. Testing is performed using state of the art equipment, including devices that provide levels of combustion gases, airborne particle load, volatile organic compounds, relative humidity and temperature.

Why should you consider ESG: 

  • Experience - hundreds of properites assessed yearly;
  • proven methodology - our methods are trusted by property owners, builders, school & government officials, physicians and attorneys;
  • Cost-effective - pricing is based (in part) on how extensive the job will be and no samples are taken without consent of the client, keeping pricing transparent and low;
  • Experienced investigators who are certified and trained in identifying the issues leading to indoor air quality issues;
  • Thoughtful communicators - ESG understands the importance of communicating the facts in an understandable manner. Our methodology is consistent from building to building and provides reliable and scientifically-based data.

Assessment includes:

  • Gathering building history
  • Visual survey of the interior and perimeter of the property
  • Airborne particle count (PM) readings in every room. Elevated airborne PM can be an indication of an IAQ issue relative to biological growth.
  • Temperature, relative humidity (RH), carbon monoxide (CO), carbon dioxide (CO2), dewpoint and total VOC measurements
  • Moisture readings of building materials
  • Moisture readings of crawl space soil, joists and sub-floor decking
  • Collection of surface and/or air samples to provide third-party validation by an AIHA-accredited lab. Outdoor air samples are always collected for comparison.
  • 30 minutes of telephone consultation time following the investigation
  • Report is delivered within 7-10 business days that identifies the source(s) of contaminants and interpretation of the testing results. Should contamination be identified, specifications/protocols can be developed which detail the steps that will need to be taken to correct the problems.
