Asbestos Testing Company
An asbestos testing company provides certified environmental inspection, bulk sample collection, and laboratory analysis services to determine whether building materials contain hazardous asbestos mineral fibers. Engaging a properly credentialed testing company is the single most reliable way to protect household members, guide renovation decisions, and satisfy regulatory compliance requirements before any demolition or major remodeling project.
Credentials and Certifications to Verify Before Hiring
Not all companies offering asbestos testing possess the necessary professional credentials to provide legally admissible and scientifically reliable results. A legitimate asbestos testing company employs state-licensed asbestos inspectors who have completed EPA Model Accreditation Plan training, passed state-approved examinations, and maintain current biennial refresher certifications. Inspectors must carry valid state licenses that can be verified through the relevant state environmental or labor department's online licensing portal.
In addition to inspector licensing, the company should perform all laboratory analysis through National Voluntary Laboratory Accreditation Program (NVLAP) or American Industrial Hygiene Association (AIHA) accredited testing facilities. These accreditation programs mandate regular proficiency testing of laboratory analysts, ensuring that Polarized Light Microscopy (PLM) and Transmission Electron Microscopy (TEM) results meet nationally recognized quality standards.
Compare key credentials, services, and accreditation standards to verify when selecting an asbestos testing company:
| Credential / Standard | Issuing Authority | Scope of Verification | How to Verify |
|---|---|---|---|
| State Inspector License | State environmental / labor dept. | Inspector competency and training | Search state licensing database online |
| EPA Model Accreditation Plan | U.S. Environmental Protection Agency | Inspector and supervisor certification | Certificate must match current state requirements |
| NVLAP Laboratory Accreditation | NIST National Voluntary Lab Accreditation | Laboratory PLM and TEM proficiency | Request lab accreditation certificate with scope |
| AIHA Laboratory Accreditation | American Industrial Hygiene Association | Environmental analysis quality management | Check AIHA directory at aiha.org/laboratory-services |
| Errors & Omissions Insurance | State-licensed environmental insurer | Professional liability coverage | Request certificate of insurance from company |
Bulk Sampling vs Air Monitoring: Two Distinct Services
A professional asbestos testing company typically offers two distinct categories of analytical services: bulk material sampling and airborne fiber air monitoring. Bulk sampling involves a certified inspector physically collecting small core specimens from suspect building materials—such as floor tiles, pipe lagging, ceiling plaster, or roofing materials—and submitting them to an NVLAP-accredited laboratory for PLM analysis to determine fiber type and percentage.
Air monitoring, by contrast, involves drawing measured volumes of ambient air through calibrated cassette filter samplers using a calibrated pump. The collected filter is then analyzed by Phase Contrast Microscopy (PCM) or Transmission Electron Microscopy (TEM) to quantify the number of airborne fibers per cubic centimeter. Air monitoring is required for OSHA compliance during active abatement projects and for final clearance certification following completed remediation.
Compare bulk sampling and air monitoring services offered by professional asbestos testing companies:
| Service Type | Sampling Method | Laboratory Analysis Method | Primary Purpose | Typical Cost |
|---|---|---|---|---|
| Bulk Material Sampling | Physical core or scrape of suspect material | Polarized Light Microscopy (PLM) | Confirm asbestos content of building materials | $25 to $75 per sample |
| Air Monitoring (PCM) | Pump draws air through MCE cassette filter | Phase Contrast Microscopy (PCM) | Quantify airborne fibers for OSHA compliance | $50 to $150 per sample |
| Air Clearance (TEM) | High-volume pump post-abatement sampling | Transmission Electron Microscopy (TEM) | Certify area safe for occupancy after abatement | $100 to $250 per sample |
The Inspection Report and Prioritization Recommendations
Upon completing field inspection and receiving laboratory analytical results, a reputable asbestos testing company compiles a detailed written report documenting every material sampled, its exact location within the structure, fiber type identified, percentage concentration, and physical condition rating. High-quality reports include annotated floor plan sketches or digital photographs referencing each sample collection point.
Crucially, the report should include a prioritized action recommendation for each identified ACM. Materials in good condition that are not subject to planned disturbance may be recommended for periodic monitoring in place. Deteriorated friable materials or those in renovation zones require immediate abatement. This prioritized guidance empowers property owners to budget effectively and address the highest-priority hazards first.

Frequently Asked Questions (8 Questions Answered)
Q1: What does an asbestos testing company actually do?
An asbestos testing company inspects a building, collects bulk material samples from suspect ACMs, submits them to an accredited lab, and provides a written report confirming whether asbestos is present and what action is recommended.
Q2: How much does asbestos testing cost from a company?
Residential asbestos inspections typically cost between $200 and $800 depending on property size, number of samples, and regional labor rates.
Q3: How do I verify an asbestos testing company is legitimate?
Check the inspector's state license, verify NVLAP lab accreditation, confirm errors-and-omissions insurance, and request references from past clients.
Q4: Can an asbestos testing company also perform removal?
Some environmental firms offer both inspection and abatement, but for maximum conflict-free accuracy, many regulators recommend using separate companies for testing and removal.
Q5: How long does an asbestos testing company take to report results?
Bulk sample PLM results are typically available within two to five business days; expedited rush results can be obtained within twenty-four hours for additional fees.
Q6: Do I need an asbestos testing company before a home renovation?
Yes. Most states require professional asbestos testing before permits are issued for significant renovation or demolition projects in pre-1990 buildings.
Q7: Can a testing company test air quality during asbestos abatement?
Yes. Professional testing companies conduct real-time personal air monitoring for abatement workers and post-abatement clearance testing for building occupants.
Q8: What happens if the asbestos testing company finds asbestos?
The company provides a written report with the fiber percentage, location, material condition, and recommended action—whether encapsulation, monitoring, or full abatement.
