Independent mold testing, indoor air quality assessments, asbestos inspections, lead testing, water testing, formaldehyde and VOC sampling, HVAC evaluations, environmental bacteria testing, construction-dust testing, and industrial hygiene consulting for Manhattan apartments, cooperative and condominium buildings, offices, schools, health care facilities, and commercial properties.
Angstrom Testing Services LLC provides independent environmental inspections, sampling, direct-reading measurements, laboratory coordination, industrial hygiene consulting, and written reporting from its Park Avenue location in Manhattan.
New York City projects may involve luxury apartments, prewar cooperative buildings, condominiums, rental properties, commercial offices, schools, medical facilities, construction sites, mechanical spaces, and other occupied buildings with complex ownership, access, HVAC, and documentation requirements.
Each project is scoped according to the property, building history, complaint, suspected source, affected areas, applicable licensing, requested testing method, and the type of report or clearance documentation needed.
This location page provides a Manhattan-focused overview. Each service links to the primary service page for more detailed information about methods, applications, limitations, and available project scopes.
Visual inspection, moisture measurements, targeted mold air or surface sampling, hidden-mold evaluation, HVAC assessment, and post-remediation verification when appropriate.

View lead testing servicesAir sampling and odor investigations involving cabinets, furniture, flooring, coatings, adhesives, renovation products, spray foam, solvents, smoke, and other suspected chemical sources.
View formaldehyde and VOC testingSampling for lead, bacteria, Legionella, heavy metals, volatile organic compounds, and selected drinking-water concerns, together with building-focused evaluation when water sources or leaks require investigation.
View water testing servicesAir and settled-dust testing for construction debris, crystalline silica, renovation dust, facade work, demolition residue, airborne particles, soot, and other building-related dust concerns.
View silica and dust testingTargeted environmental bacteria sampling for sewage, surfaces, air, HVAC or selected water concerns, plus separate Legionella sampling for building water systems and cooling-tower projects.
View bacteria testing servicesRF field measurements for rooftop antennas, cellular installations and occupied areas where building owners, residents, workers or project teams need documented radiofrequency exposure measurements.
View RF exposure testingEvaluation of accessible fan-coil units, air handlers, blower compartments, coils, condensate pans, filters, duct liner, registers, and HVAC-related mold, dust, soot, moisture, or odor concerns.
View HVAC mold assessmentsManhattan projects often involve shared walls, stacked plumbing, building risers, exterior facades, fan-coil or PTAC systems, neighboring apartments, active renovation and detailed access or documentation requirements.
Prewar and older buildings may contain legacy lead paint, asbestos-containing materials or other components that require evaluation before renovation, after disturbance, or during due diligence.
Lead testing servicesWater can migrate from plumbing, bathrooms, roofs, terraces, window assemblies, facade defects or neighboring units. Moisture mapping and targeted mold assessment can help define affected areas.
Mold testing and inspectionCondensate pans, coils, filters, blower compartments, liners and nearby finishes may require inspection when there are odors, moisture, dust or microbial concerns.
HVAC mold assessmentTobacco smoke, cannabis smoke, cooking odors, renovation emissions and other contaminants can move through corridors, shafts, penetrations and pressure pathways between spaces.
Indoor air quality testingInterior renovation, demolition and exterior facade work can generate dust that may warrant project-specific evaluation for silica, lead, asbestos or general particulate contamination.
Silica and dust testingLarger residential and commercial buildings may require drinking-water testing, bacterial investigation or a separate Legionella sampling plan for building water systems.
Legionella testingA useful assessment considers how a New York City building is constructed, occupied, ventilated, maintained, and renovated. Testing should answer a defined question rather than simply collect unrelated samples.
Apartment investigations may require review of exterior walls, windows, risers, plumbing lines, radiator covers, fan-coil units, floor and wall penetrations, neighboring spaces, common corridors, and prior renovation or water-damage history.
Office, school, medical, retail, and institutional projects may require ventilation review, complaint mapping, direct-reading measurements, exposure sampling, HVAC assessment, water-system testing, construction monitoring, and documentation for management or regulatory review.
We review the property type, location, complaint, affected spaces, building history, suspected source, prior work, and reason for testing.
Inspection activities, instruments, sample types, locations, laboratory methods, access needs, and reporting requirements are selected for the objective.
Accessible areas are evaluated, documented, measured, or sampled according to the agreed scope and conditions present during the site visit.
Findings are interpreted with the observations, sample locations, laboratory results, comparison data, project limitations, and intended use.
The Park Avenue location supports environmental testing projects throughout Manhattan and the five boroughs. Service availability depends on the project type, required licensing, building access, scheduling, site conditions, and requested turnaround time.
Projects may involve individual apartments, entire residential buildings, common areas, mechanical rooms, commercial spaces, schools, health care facilities, offices, retail properties, and construction or renovation sites.
Angstrom provides mold testing, indoor air quality assessments, asbestos testing, lead paint and lead dust testing, water testing, formaldehyde and VOC testing, silica and construction-dust testing, HVAC and fan-coil assessment, bacteria testing, Legionella testing, and related industrial hygiene consulting.
Yes. Projects may involve one apartment, several affected units, common areas, mechanical spaces, exterior-wall or leak pathways, entire residential buildings, commercial properties, or institutional facilities. The scope should match the question that needs to be answered.
Yes. Angstrom works with property managers, cooperative and condominium boards, shareholders, unit owners, landlords, tenants, attorneys, contractors, architects, engineers, and other project stakeholders.
No. Angstrom provides independent testing, inspection, sampling, consulting, and reporting. We do not perform remediation, abatement, duct cleaning, restoration, plumbing repair, reconstruction, or cleanup contracting.
Building investigations may include visual inspection, moisture measurements, thermal imaging, review of leak patterns, targeted sampling, and other source-evaluation techniques. The appropriate scope depends on the suspected pathway, building system, access, and conditions present during the assessment.
Yes. The appropriate scope depends on the work performed and contaminant of concern. Projects may involve settled dust, airborne particles, silica, lead, asbestos or other project-specific measurements and laboratory analyses.
Yes. An investigation may include building and pressure-pathway observations, direct-reading measurements, surface or air sampling where appropriate, and documentation of conditions present during the assessment. The testing scope depends on the suspected source.
Depending on the agreed scope, documentation may include inspection findings, sample locations, field measurements, photographs, laboratory results, interpretation, limitations, and recommended next steps.
Testing can help evaluate possible sources, but odor and indoor air quality investigations often require a combination of building-history review, inspection, source tracking, field measurements, targeted sampling, and interpretation of conditions present during the assessment.
No. Environmental testing evaluates selected building conditions and contaminants. It does not diagnose illness or determine medical causation. Health concerns should be discussed with an appropriate health care professional.
Describe the property type, neighborhood, affected rooms or building areas, odor, moisture, dust, mold, asbestos, lead, water, chemical vapor, HVAC, construction, or documentation concern. Angstrom can help define an appropriate inspection and testing scope for the project.
