A-1 Certified Environmental Services has offered Mold Testing, Indoor Air Quality Tesitn and VOC Testing in the California region for over 20 years. We cover all the major cities of Los Angeles, Long Beach, San Francisco, San Jose, Sacramento, San Diego and Oakland. We also have an extensive range of other indoor air quality testing.

We are not affiliated with any mold removal companies or mold remediation, and we promise that our customers will receive objective, non-bias test results! What do we mean by “unbiased?” We mean having the testing performed by a company that only offers testing and does not also provide any remediation (clean up services). As a result, a testing-only company does not have the potential for a conflict of interest like a remediation company does if you hire them to perform the initial testing. If you want to get honest answers about the air quality within your Los Angeles or San Francisco home, A-1 Certified Environmental Services is an excellent choice. Here are some indoor air quality testing basics.
