As a New York State-licensed company, we provide next-day service with guaranteed test results at competitive rates. Call us today for professional mold inspections that you can trust!

We proudly serve New York City, Brooklyn, Long Island, Queens, the Bronx, Westchester, and the surrounding NYC tri-state area. Our mold testing and mold inspection services assist homeowners, property managers, healthcare facilities, attorneys, insurance companies, schools, and more. We evaluate water damage and mold growth to ensure your indoor spaces are safe.


Mold Testing and Mold Inspections You Can Trust

We work exclusively with New York State-accredited laboratories to analyze samples collected during our mold  inspections. This ensures the highest accuracy for test results, helping you identify and address mold problems effectively.

Our detailed mold inspection reports include NY State-mandated mold remediation protocols, guiding contractors on the necessary steps to resolve mold issues. We also provide follow-up mold clearance inspections to verify successful mold remediation.


Our Comprehensive Mold Inspection Process

  1. Assess musty odors and signs of mold growth.
  2. Identify water-damaged surfaces prone to mold.
  3. Perform air sampling to analyze indoor air quality for mold spores.
  4. Collect surface and bulk samples for laboratory analysis.
  5. Measure moisture levels to detect water damage sources, such as leaks or condensation.
  6. Develop a tailored mold remediation plan based on test results.
  7. Recommend additional evaluations as necessary.
  8. Deliver a verbal summary during the inspection and a full report after lab results are available (typically within 2–3 days).

Why Mold Testing is Essential

Excessive moisture in buildings creates an ideal environment for mold growth, often in hidden areas like wall cavities or beneath floors. Mold exposure can lead to serious health problems, including respiratory issues, sinus infections, and asthma exacerbation. Organizations like the Institute of Medicine (IOM) and World Health Organization (WHO) link damp environments to increased risks of allergies and lung conditions.

Our mold assessments evaluate both visible and hidden mold growth to protect your health and property.

Mold Air Testing

Air sampling is a critical part of our mold inspection services. NY State-licensed Mold Assessors evaluate airborne mold spores, comparing indoor levels to outdoor baselines. Elevated indoor mold levels, especially of “marker fungi” like Penicillium, Aspergillus, and Stachybotrys, indicate water damage or health risks. Call us to schedule a mold inspection and ensure safe air quality for your family.

Hidden Mold Testing

Hidden mold often develops in concealed areas, such as inside walls or beneath floors. During our mold inspections, surface samples are collected to detect mold spores that may affect air quality. Accurate lab analysis identifies mold spore types, helping us pinpoint issues. Trust us for thorough mold testing and mold inspections in NYC, Long Island, and Westchester.

Call Angstrom Testing Services to have a mold Inspector perform a mold inspection in your home by performing a visual inspection, evaluating odors, taking moisture measurements, and by taking airborne mold samples to evaluate whether hidden mold growth conditions may be present.

E.R.M.I.

The Environmental Relative Moldiness Index (ERMI) is a scientific method to evaluate the mold burden in your home. By analyzing dust samples with advanced DNA-based techniques, we determine the presence of mold species linked to water damage. This helps assess whether your home has a mold problem. Call Angstrom Testing Services to learn more about our ERMI-based mold testing.

Mold Spores in Carpets

Airborne mold spores settle and accumulated on the floors and other horizontal surfaces over time. Sources of airborne mold spores include visible and hidden mold growth on surfaces indoors and the outdoor air, which enters homes and apartments through open windows and doors. Therefore, it is essential to periodically HEPA vacuum and damp wipe floors and furniture/furnishings to keep mold spore concentrations in settled dust deposits at low levels.

In carpets however, mold spores settle and accumulate deep in the carpet weave, despite recurrent vacuuming. When carpets become wet during a water intrusion event or during periods of high prolonged humidity, mold spore levels (and levels of bacteria) increase exponentially. Wet cleaning methods, even when anti-microbial disinfectant cleaners are used, also cause levels of mold spores to drastically increase.

When carpets are disturbed, dust containing elevated levels of mold spores and bacteria inside the carpet is unavoidably plumed into the air. This airborne mold spore- and bacteria-laden dust can cause allergy-like symptoms in sensitive individuals. Asthmatics may also experience respiratory distress if significant quantities of airborne dust from the carpet are inhaled.

Samples of dust may be collected from carpets and cultured during laboratory analysis to evaluate levels of mold spores and bacteria in the carpet. If levels of mold and bacteria are substantially higher than background levels, the carpets should be disposed of.

They were awesome! They really exert the effort to make sure the mold inspection is done correctly. I wanted to test the air on a condo that we were purchasing (because it had a strong damp smell when you walked in). Thanks, Angstrom & Team for helping me in time.

Angstrom tested the water at each of the sinks in our daycare center for lead. They helped us get our license from the New York City Department of Health. They arrived on time and got the job done without any hassles and provided all the paperwork that I needed. Thanks again! Philip Bleeker
