Testing Focused on the Building Conditions and the Evidence
Angstrom Testing Services LLC evaluates indoor environmental and industrial hygiene concerns involving mold, asbestos, lead, drinking water, crystalline silica, formaldehyde, volatile organic compounds, chemical odors, mercury vapor, bacteria, Legionella, mycotoxins, smoke residue, ventilation, HVAC systems, and radiofrequency exposure.
We provide inspection, testing, sampling, laboratory coordination, consulting, and written reporting. We do not perform mold remediation, asbestos abatement, lead abatement, duct cleaning, hazardous-material cleanup, or restoration contracting.
Separating testing from corrective work helps reduce conflicts of interest and keeps the findings centered on observed conditions, selected sample locations, field measurements, analytical results, project objectives, and appropriate limitations.

A Clear Separation Between Assessment and Corrective Work
Appropriate Methods
Methods, instruments, media, sample duration, laboratory capability, reporting limits, and quality-control needs are considered for the objective.
Defensible Documentation
Reports may document observations, sample locations, field conditions, analytical results, interpretation, limitations, and recommended next steps.
No Cleanup Sales Conflict
Because Angstrom does not sell remediation or abatement work, testing findings are not used to generate cleanup-contracting revenue.
How an assessment works
From Initial Concern to Written Findings
Discuss the Concern
We review the property, complaint, history, affected areas, previous work, occupancy, timing, and type of documentation needed.
Develop the Scope
The inspection, instruments, sample types, locations, laboratories, and reporting approach are selected for the project objective.
Inspect and Sample
Accessible conditions are evaluated and air, dust, surface, water, material, or direct-reading measurements are collected when appropriate.
Analyze the Data
Laboratory and field data are reviewed with the sample locations, building conditions, comparison samples, and relevant technical context.
Report the Findings
The final documentation explains what was evaluated, what the results show, important limitations, and recommended next steps when warranted.

Frequently Asked Questions
What types of environmental testing does Angstrom provide?
Services include indoor air quality testing, mold inspection and sampling, asbestos testing, lead paint and lead dust testing, water testing, Legionella testing, formaldehyde and VOC testing, mercury vapor testing, silica dust testing, bacteria testing, mycotoxin testing, HVAC mold assessment, RF exposure testing, odor investigations, and related industrial hygiene consulting.
Do you perform remediation, abatement, cleanup, or duct cleaning?
No. Angstrom provides independent inspection, testing, sampling, consulting, laboratory coordination, and reporting. We do not perform remediation, asbestos abatement, lead abatement, hazardous-material cleanup, restoration, or duct-cleaning contracting.
What can an environmental assessment include?
Depending on the concern, an assessment may include site-history review, visual inspection, moisture measurements, air sampling, surface sampling, dust sampling, water sampling, material sampling, direct-reading instruments, laboratory analysis, photographs, field notes, and a written report.
Will testing identify the source of an odor or indoor air quality complaint?
Testing can help evaluate possible sources, but source identification often requires a combination of inspection, building-history review, source tracking, direct-reading measurements, targeted samples, HVAC observations, and comparison data. Some odors are intermittent or may not be present during the inspection.
Do you provide a written report?
Yes, when included in the agreed project scope. Documentation may include the inspection observations, sampling methods and locations, field conditions, laboratory results, interpretation, limitations, photographs, and recommended next steps.
What areas do you serve?
Angstrom serves New York City, Long Island, Westchester, southern Connecticut, eastern New Jersey, and nearby areas. Project availability depends on the service, urgency, site conditions, equipment needs, laboratory schedule, and scope of work.
