Asbestos testing is the laboratory analysis side of asbestos work. You cannot tell by looking whether a material contains asbestos; only lab analysis confirms or rules out asbestos-containing material. Enviro Consulting Services provides asbestos testing in Spokane, WA with sample collection by an EPA AHERA Certified inspector, chain of custody documented, and analysis performed by accredited laboratories using Polarized Light Microscopy (PLM) or, when required, Transmission Electron Microscopy (TEM).
Testing only. We do not perform asbestos removal, abatement, or disposal. Keeping testing independent from abatement is what makes the lab results credible for regulators, lenders, insurers, and attorneys.
Different scenarios call for different analytical methods. The right method depends on the material, the regulatory framework, and the decision the result will drive.
The standard method for analyzing bulk samples of suspect asbestos-containing materials. PLM identifies asbestos type (chrysotile, amosite, crocidolite, etc.) and estimates concentration as a percentage range. EPA method for most bulk material scenarios.
A more sensitive PLM variant used when initial results are near the regulatory threshold (below 1 percent). Point counting produces a more precise percentage estimate in the critical range.
Used for specific applications including non-friable organically-bound (NOB) materials like floor tiles and roofing, some clearance scenarios, and situations where PLM is not definitive. TEM has higher sensitivity and resolution but longer turnaround.
Air sample analysis for airborne asbestos fibers. Used during or after abatement projects to verify worker exposure levels and final clearance. PCM is the standard method for most abatement-related air testing.
Before cutting, sanding, or demolishing any material in a pre-1980 building, representative samples of suspect materials should be tested. A negative result means the material can be disturbed without asbestos-specific steps; a positive result means a licensed abatement contractor is needed for the asbestos-containing materials in the work area.
Washington State regulations require a pre-demolition asbestos survey that includes sampling and analysis of suspect materials. The lab results support the demolition notification filed with the WA Department of Labor and Industries.
A broken floor tile, a damaged pipe wrap, a renovation started without inspection: testing confirms what the disturbed material contains and informs the cleanup and documentation steps that follow.
Buyers of pre-1980 properties often scope targeted testing of specific suspect materials during the inspection contingency. A positive result for material in the work area of a planned renovation is a material consideration; a negative result is documentation that protects the buyer.
After a licensed abatement contractor completes asbestos abatement, third-party air sampling verifies that airborne fiber levels meet clearance criteria. Clearance testing should be performed by a party not holding the abatement contract.
A homeowner who has lived in a pre-1980 house for years and wants documented knowledge about a specific material (a popcorn ceiling, a 9x9 tile floor, pipe wrap in the basement): testing produces the answer without requiring a larger inspection scope.
Asbestos inspection is the visual survey of suspect asbestos-containing materials throughout a building. Asbestos testing is the laboratory analysis of samples collected during or after that inspection.
Most pre-renovation and pre-demolition scenarios require both: the inspection to identify suspect materials and determine sampling scope, and the testing to confirm whether those materials contain asbestos and at what concentration. Testing without an inspection is possible when the material and location are already identified (a specific suspect tile, a known pipe wrap) and the question is narrow.

Lab results are only as defensible as the samples they come from. Both of our inspectors hold EPA AHERA Certified Asbestos Building Inspector credentials. Samples collected by credentialed personnel following accepted protocols and documented chain of custody produce results that hold up in front of a regulator, a lender, an insurer, or opposing counsel.
Samples go to laboratories accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos analysis and by the American Industrial Hygiene Association (AIHA) for air sample analysis. Accreditation is the difference between a credible lab result and a lab result a regulator can dismiss.
We perform inspection and testing only. We do not hold abatement contracts. That separation is what makes our testing data defensible in regulated scenarios; a firm that also bids on abatement has an incentive to produce findings that support the follow-on work.
The written report includes sample location, chain of custody, laboratory results, regulatory context (NESHAP and WA L&I thresholds), and a plain-language interpretation of what the data mean. Formatted to be shared directly with the WA Department of Labor and Industries, a lender, an insurer, an attorney, or a licensed abatement contractor.
Predictable. Transparent. Designed for people making decisions with real money on the line.
We talk about the building, the project triggering the testing (renovation, demolition, post-disturbance, clearance), the materials of concern, and the decision the results need to support. You receive a flat quote based on sample count and analysis method.
An EPA AHERA Certified inspector collects representative samples of the suspect materials following accepted protocols, documents chain of custody, and photographs sample locations.
Samples are shipped to an accredited laboratory. Standard PLM turnaround is 3-5 business days; point counting and TEM analysis run longer. Rush turnaround is available for transaction-sensitive scopes.
We deliver a written report documenting sample locations, chain of custody, laboratory results (asbestos type and concentration), regulatory context, and a plain-language interpretation. The report is formatted to be shared directly with the audience that needs it.
If a licensed abatement contractor, regulator, lender, insurer, or attorney has questions about the report, we respond. The relationship does not end at delivery.
Asbestos testing produces the definitive answer that visual inspection cannot: what is in the material, and at what concentration. For regulated scenarios (pre-demolition, pre-renovation, AHERA compliance), the lab result is what the regulatory framework actually requires.
A lab result is only as good as the sample it came from. A sample collected without chain of custody, without accepted protocols, or by someone without the credentials is a lab result a regulator can dismiss or opposing counsel can challenge. EPA AHERA Certified inspectors collect samples for a reason: the credential exists because the discipline matters.
Asbestos analysis is performed by labs accredited by NVLAP (National Voluntary Laboratory Accreditation Program) for bulk samples and by AIHA (American Industrial Hygiene Association) for air samples. Using an accredited lab is not a formality; it is the mechanism by which the analytical results are defensible under federal and state regulatory frameworks.
The firm that holds the abatement contract has an incentive to produce findings that support that contract. That is not necessarily fraudulent, but it is a conflict of interest that regulators and opposing counsel are aware of. A testing firm that does not also perform abatement has no such conflict. That is why we structure the firm the way we do.
No. Enviro Consulting Services performs inspection, sampling, and testing only. Asbestos removal, abatement, and disposal are handled by a separately retained, licensed asbestos abatement contractor. Keeping testing independent from abatement is what makes our lab results credible in regulated scenarios.
It depends on the material and the scope. EPA protocols specify minimum sample counts by material type and square footage. For a pre-demolition survey on a residential building, sample count scales with the number of distinct suspect materials. For targeted testing of a specific material, one to three samples may be sufficient. Sample count is scoped in the first call.
Standard PLM turnaround is 3-5 business days. Point counting adds a few days. TEM analysis takes 5-10 business days. Rush turnaround is available on most scopes for transaction-sensitive or regulatory-deadline scenarios; ask during the scoping call.
The 1 percent threshold has specific regulatory meaning under federal NESHAP rules. A result below 1 percent may still be regulated depending on the material, the state rules that apply, and the scope of work planned. When a result is near the threshold, point counting can produce a more precise estimate. The report interprets the result against the applicable regulatory framework.
Yes. Phase Contrast Microscopy (PCM) air testing is the standard method for abatement-related air monitoring, including worker exposure assessment and post-abatement clearance. Clearance air testing should be performed by a party not holding the abatement contract; we are structured to serve as that independent third party.
We generally decline to broker lab analysis on samples collected by uncredentialed parties without chain of custody because the result is not defensible. If the samples were collected by a credentialed inspector with documented chain of custody, we can sometimes coordinate the analysis; ask during the scoping call.
