Mold Services: On-Site Diagnostic Inspection & Lab Testing for Mold and Other Indoor Air Quality Concerns
This page provides contact information for expert services and in-depth information about indoor air quality problems: causes of respiratory illness or other symptoms such as neurological or psychological problems, air quality investigation methods, and remediation procedures such as mold cleanup, handling toxic mold contamination, and building or HVAC repairs.
At MOLD INSPECTORS & MOLD TESTERS we list mold and other environmental test consultants whose work is familiar to us. For on-site building diagnostic inspections & testing also see the list of inspectors and specialists at Directory of Professionals to Inspect or Test a Building
.CONTACT INFORMATION is here
Our building investigation services include thorough on-site studies for residential and commercial buildings in New York, New Jersey, and Connecticut, with service available world wide on advance notice. We also provide expert 24-hour mold testing lab service for our clients and the public. The result of field and lab work is a complete field investigation report indicating our field findings, laboratory test results, and detailing just what remediation or other actions are appropriate. Basic medical information about allergenic or toxic mold or other contaminants is also included when available.
We investigate complaints of respiratory illness, asthma, allergies, neurological and other health concerns, and we identify sources of these and other hazards that may contribute to a wide range of health complaints associated with buildings. To identify and address indoor air quality problems, we identify conditions which may cause or contribute to allergy, asthma, "sick building syndrome -- SBS," other respiratory illness and distress, as well as possible neurological or other health problems which may be caused or aggravated by mold or other particles in the air.
Field investigation methods include taking site and client history, visual inspection of the property and building and its mechanical systems, bulk/surface/vacuum sampling, calibrated air sampling combined with light microscopy and laboratory analysis to identify common bioaerosols, allergens, pet dander, dust mites, fleas, mold, pollen, fibers, and other potential irritants. We also are equipped to test for specific contaminant gases such as produced by building fires or heating equipment as well as mold or other contaminants.
Our Indoor Gas Sampling Plan for Residential Buildings describes gas testing procedures, instruments, detection limits, and it lists some of the toxic (or other) indoor gases for which we can test, depending on the building complaint and building conditions.
No one needs to wield an axe to investigate a building. And no one needs to bury important findings among pages of vague language. We use special equipment such as this borescope permitting examination of hidden wall/ceiling/floor cavities using non-destructive methods. We may use other equipment to actually obtain particle samples from wall/ceiling/floor cavities by the Wall Check™ method, When conditions warrant and permission is obtained, we also are equipped to make modest test cuts or to perform other more invasive inspection methods. A variety of non-invasive infra-red and moisture measuring tools may also be employed if recent or current leaks are suspected.
Our mold and air quality investigation report includes field observations, laboratory test results, medical information regarding toxic or allergenic mold or other contaminants identified, and remediation advice including both mold cleanup and building repairs which are necessary to help avoid future problems. Technical documentation is accompanied by photo documentation of field and lab findings. A simple report summary provides a "guide to action" for each property we inspect.
Our laboratory procedures are described below at Laboratory Services. More information about our indoor air mold testing and field and laboratory investigation methodologies and a description of some of our equipment is at Investigation methodology.
Principal investigator & website author: Daniel Friedman, Member: American Industrial Hygienists Assoc. AIHA#149892, American Society of Home Inspectors ASHI#00577, BOCA, IAEI, ICBO, NPCA Mr. Friedman offers sick building, air quality, and mold investigations and home inspections and for problem diagnosis, research, expert witness, legal documentation, & failure claims assistance.

Our laboratory service includes analysis of our own expert-prepared field samples as well as processing of consumer-prepared bulk-tape mail-in samples of mold or other particles. Our mold testing lab provides identification services for bioaerosols such as mold, mildew, dust mites, pollen, and other allergens. We have considerable experience examining samples collected on tape, Zefon cassettes, MCE filter cassettes, slides, impaction air samplers, carpet, furniture, and other soft-goods vacuum samples, and in bulk material. Mold culture and bacterial surface contamination evaluation is available, and we also offer testing for carbon monoxide or carbon dioxide, formaldehyde, and other gases.
Our laboratory education and experience include fungal spore, organic, and inorganic particle and fiber identification, mold culture methods and culture speciation. Our equipment education and experience include biological microscopy, forensic microscopy, particle identification using microscopic particle manipulation, microchemistry, transmitted light microscopy, polarized light microscopy, dispersion staining, determination of refractive index, interference patterns, phase-contrast, darkfield, focal screening, and other advanced techniques.
In the lab we make use of a variety of microscopes: low-power stereoscopic examination of samples for characterization and high-power microscopic examination (up to 1920x) for particle identification using both transmitted and polarized light for identification of biological particles such as mold spores, pollen grains, animal allergens, and non-biological particles in house dust and debris. These methods help assure that the lab report accurately represents the character of the samples which were submitted.
Mobile Microscopy Lab: For immediate on-site particle determination where emergency response or remediation/salvage operation evaluation is necessary we offer mobile field microscopy lab service including field preparation of test samples and light microscopic examination for particle identification.
Field samples are used to prepare slides for examination by light microscope. Our own field work collects mold or biological particle samples using a variety of methods. From the public our lab also accepts mold surface samples using clear tape. Chemical treatment and mounting media are selected based on the sample type, often including potassium hydroxide, acid or basic fuchsin, Calberla's solution, lacto phenol cotton blue, or other preparations. When lab work is in support of legal proceedings or if otherwise appropriate we prepare permanent-mount slides using glycerine jelly or other media. Slides are examined at magnifications of 10x, 100x, 400x, and 1000x using tungsten and polarized light, darkfield, etc. as appropriate.
Identification of toxic mold species:
A detailed written mold test laboratory report of laboratory finding, medical information, and recommendations is provided.
The lab report describes:
which in special cases may still be diagnostic.
Using clear, specific definitions of "mold levels"
Independent inspectors as well as many building owners or occupants may also use our mold testing laboratory service. If you do not want to bring a professional investigator to your property, here are instructions explaining how to collect and mail mold samples to our lab for identification, analysis, and advice.
If you wish to send samples collected by means other than described in our guidelines, please call first for special instructions and fees. If you have questions about our instructions for mailing a mold sample to the lab or if you need to request special field or lab services, contact our lab to request services.

OTHER IAQ ISSUES: How To Find and Address Other Indoor Air or Indoor Environment Contaminants Besides Mold
Mold or allergens may not be the only or even the main indoor environmental contaminant. Don't let media attention to mold cause so much enviro-scare fear that other, possibly more urgent hazards go un-addressed.
