Environmental Testing

Environmental testing is the scientific process of sampling and analyzing a property for hazardous substances and conditions. It's the critical first step in identifying problems like asbestos, mold, lead, and bacterial contamination — and in verifying that remediation work has been completed successfully. Without accurate testing, you're operating in the dark.

Our testing services cover a wide range of hazards. Asbestos testing identifies asbestos-containing materials in older buildings before renovation or demolition disturbs them. Mold testing determines the type and extent of mold growth and can pinpoint hidden mold that's not visible. Lead testing detects lead-based paint and lead in soil and water. Bacteria testing identifies harmful pathogens, including after sewage backup or flooding. And water quality testing checks for contaminants that affect drinking water safety.

We begin each testing project with a discussion of your concerns and a visual assessment of the property. We then collect samples using proper protocols and chain-of-custody procedures, ensuring accurate, defensible results. Samples are analyzed by independent, certified laboratories, and we provide you with a clear, comprehensive report of the findings.

Why does professional environmental testing matter? DIY test kits and guesswork are unreliable. They can produce false negatives that leave real hazards undetected, or false positives that cause unnecessary worry and expense. Certified testing provides the accurate, actionable data you need. And when testing reveals a problem, STOS is uniquely positioned to help — our environmental and restoration team can perform the remediation right away, from asbestos abatement and mold remediation to water and fire damage restoration.

In Arizona, environmental testing is especially important given the state's monsoon season and associated moisture problems, as well as the prevalence of older buildings that may contain asbestos or lead. Whether you're a homeowner, a real estate professional, a property manager, or a business owner, accurate environmental testing protects your health and your investment.
