Environmental Assessments & Testing

At OHST we believe everyone deserves to feel safe and confident about their property and environment. That’s why we provide clear, reliable, and flexible environmental assessments and testing services for homeowners, small businesses, real estate professionals, property managers, contractors, developers, and industrial facility operators.

Our team specializes in industrial hygiene investigations, environmental assessments, and safety audits.

Industrial Hygiene Investigations

Asbestos Surveys
Our asbestos testing and assessment service helps property owners, businesses, and contractors confirm and identify potential asbestos-containing materials. We conduct comprehensive inspections, collect samples for certified laboratory analysis, and provide clear detailed reports on locations, findings, and conditions. With our guidance, clients can make informed decisions about safety, compliance, and next steps for management or remediation.

Lead-Based Paint Inspections
Older homes and structures often contain hidden lead-coating hazards. We offer safe, certified lead testing for paint, dust, water, and soil, helping you protect families, employees, and tenants. Reports can be tailored for homeowners, property managers, or compliance-level documentation for remediation projects.

Mold Assessments & Remediation Guidance
Mold can cause health concerns and property damage if left untreated. Our inspections target source location, measure the extent of contamination, and outline clear next steps. For use by contractors or remediation firms, we provide detailed reporting with confirmatory lab data, helpful for remediation responses.

Indoor Air Quality Testing (IAQ)
We test for allergens, mold spores, volatile organic compounds (VOCs), and other pollutants that can affect your comfort and health. Whether you’re interested in  a simple summary of your air quality or a comprehensive industrial hygiene report, we provide results you can trust.
