Indoor air quality testing is done to access the contaminants present in an indoor environment.  Office indoor air quality improvements will improve worker comfort and increase productivity. Our Indoor Air Quality testing uses OSHA, NIOSH, and  EPA testing procedures to investigate I.A.Q. complaints or give you a profile of your air. Hundreds of compounds can be tested for including gases, chemicals, dust and biological samples. We take special care in instrument calibration and sample handling to produce accurate and reliable results. Our results are compared with controlled samples to ensure accurate data. We offer services for Residential and Businesses. To learn more about indoor air quality visit the EPA's Site for Indoor Air Quality, EPA California, California's Department of Public Health, and Air Resources Page.

Mold Testing is done to identify mold and resolve moisture problems. Mold Testing is done by taking air samples and comparing inside and outside spore numbers and can determine if a building has a high amount of mold present.  Mold and moisture testing will help to assess problems by determining if high mold levels exist and if remediation work is necessary.  If left unresolved mold and moisture issues create substantial property damage over time.   Read more about our mold services, mold problems, and mold scams in F.A.Q. For more general information on mold you also visit the Department of Health, EPA's mold, home page and the CDC's mold home page.


Mold Inspections look for any areas affected by mold and moisture.  During our Inspections we take moisture readings of interior walls in the sample area to see if there is a suitable environment for mold to grow.  Our experts are trained scientists and have a background in the building construction industry.  So we can relate mold data to a building and provide you practical solutions if a problem is found.  We can identify and asses any mold problem you may have.

Consulting services meet your special and specific environmental needs. Risk Management services are offered to help assess environmental conditions present and to help determine if action should be taken to minimize risks and exposure.  Resources on Environmental Risk Management.
