Air Testing

Mold Testing and Mold Inspection Services

Airborne Mold Testing
Air sampling for laboratory analysis is performed by NY state licensed Mold Assessors to evaluate levels of airborne mold spores to determine whether there may be a health risk to you or your family. 

Laboratory results are interpreted by comparing indoor levels to outdoor levels. In relative terms, if the indoor air contains significantly higher levels of any molds related to water damage conditions or occupant health complaints (“marker fungi”) than are present in the outdoor air, then appropriate action should be taken to identify and remediate the underlying mold growth problem(s). The primary “marker fungi” are Penicillium, Aspergillus, and Stachybotrys.
Moisture Testing

Moisture Measurements
Based upon the reported history of water damage and rainwater intrusion in your home or office, we will take moisture measurements readings of the affected floor, wall, and ceiling surfaces to evaluate or confirm whether moisture intrusion problems may be ongoing and require further evaluation. 

Excessive moisture in building materials can cause mold to grow, which may occur inside wall and ceiling cavities and/or beneath the floors. Living or working in damp indoor environments ha been definitively associated with respiratory problems by the Institute of Medicine (IOM) and the World Health Organization (WHO).
Following is a Summary of the Scope of our Mold Inspections:

1. Evaluate levels of musty/mold-growth related odors.
2. Identify surfaces displaying water damage and/or mold growth conditions.
3. Take air samples for laboratory analysis as may be necessary to determine if indoor air quality is being affected mold growth conditions.
4. Take surface/bulk samples for laboratory analysis to evaluate/document mold growth as may be necessary.
5. Take moisture measurements and evaluate water damage sources (eg. rainwater intrusion, plumbing leaks, condensation) in areas displaying water damage or that are susceptible to becoming wet. 
6. Develop a mold remediation plan based upon the observations and test results.
7. Recommend corrective actions or further evaluation by an architect/engineer/ plumber as may be necessary.
8. Provide a verbal report of any preliminary findings at the time of the inspection. The written report is issued within 1-2 weeks of receipt of all laboratory results (turn around time for lab results is one week).

Our Mold Inspection Reports include a summary of our significant observations, test results, and site-specific remediation protocols that fully describe the necessary mold removal work, safe work practices and containment work, HEPA vacuuming/cleaning work, and disinfection & encapsulation work.


Clearance Mold Inspections and Testing
Angstrom Testing Services provides post mold remediation clearance inspections after remediation work is performed by mold remediation contractors to determine whether the mold remediation work was properly performed. The inspection includes an evaluation of levels of musty odors, settled dust, moisture, and airborne mold. If a work area passes clearance, then a clearance document will be written stating that clearance has been achieved for your real estate records. 


If you suspect that your indoor home environment is contributing to your adverse health symptoms, respiratory problems or asthma-like symptoms, or if your asthma and allergies become significantly worse when you spend time indoors, please call Angstrom Testing Services to schedule a mold inspection. You may have a hidden mold problem.

Surface Mold Testing
Surface mold samples are collected to evaluate whether molds are growing on the surfaces of the walls, ceilings, and/or floors that could potentially adversely affect indoor air quality. 

Samples are sent to an accredited  laboratory, where microscopic examination of the sample is performed by accredited laboratory personnel to identify all of the mold spore types that are present in the samples, regardless of whether the molds are dead or alive.  
Mold Inspections - Hidden Mold and Mold Testing
Hidden mold growth conditions often exist beneath wood floors that measure wet or that have sustained water damage. 

Moisture measurements can be taken using a hand-held moisture meter, which can often uncover hidden mold growth conditions, especially in basements, where wood floors and carpets are often installed directly over moist concrete floor slabs.

Hidden mold growth conditions are often present beneath floors or on damp/wet sheetrock surfaces beneath base mouldings, which prevent sheetrock from drying out after they have become wet. 

Call Angstrom Testing Services to have a mold Inspector perform an assessment of 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. 

Please note that in 2004, the Institute of Medicine stated in its report entitled Damp Indoor Spaces and Health that there is sufficient evidence of an association between exposure to mold and other agents in damp indoor environments and upper respiratory tract symptoms, coughing, wheezing, asthma symptoms (in sensitized individuals with asthma), hypersensitivity pneumonitis (in susceptible persons), respiratory infections and fungus-related illnesses (in immuno-compromised persons), and colonization and potential lung infection in individuals with chronic pulmonary disorders. The World Health Organization stated in its report entitled Dampness and Mould (2009) that “There is sufficient epidemiological evidence of associations between dampness or mould and asthma development, asthma exacerbation, current asthma, respiratory infections, upper respiratory tract symptoms, cough, wheeze and dyspnoea.”
