Professional Mold Assessment
Our mold assessment (sometimes referred to as a mold survey) of homes
and commercial buildings is performed adhering to standard methods, practices,
and protocols of the Certified Mold Inspectors & Contractors Institute
and the EAA (Environmental Assessment Association). It encompasses a wide range
of data sources, giving you the most accurate conclusions possible.
To protect your property from accidental contamination, our field technicians
put on new full shoe coverings (booties) before entering your premises. And
you will notice their safety suits and respirators they utilize to protect
themselves from possible toxin contact.
Because mold cannot live without moisture, sources of
moisture are one of the focal points of our investigation.
During the thorough visual inspection of your structure (
including the attic, crawl spaces and basement) we examine:
- heating, ventilating and air conditioning
- the moisture content of floors, walls and
ceilings--even beneath surfaces--using a non-invasive
- the humidity of the indoor air, using a properly
- all water-damaged areas.
- an examination of moisture barriers for proper
installation and condensation occurrence, via a fiber
optics scope and existing wall openings (whenever
- discovery of the point of water intrusion in
- a definitive report of adjacent and contiguous
property contamination sources
- an assessment of property damage
- an assessment of other chemical contamination, such
as benzene, formaldehyde, etc...
- other professional support as needed.
Your field representative's training ensures that,
throughout this portion of the inspection, there is consistency in
collection protocols, minimizing the possibility of sample contamination.
equipment allows us to collect specimens from:
It is primarily these samples that determine airborne mold
spore counts. Proximate outdoor air is also tested (for the control sample)
1. For reliable results, the equipment used includes a controlled volume
air pump, which draws air through Air-O-Cell ® cassettes. In special
cases where the species of mold needs to be identified, a collection
plate with a growth medium is placed in a viable impactor (microbial
particle sampler), in which one hour of spore settling time is replicated
in five minutes.
Wall Interior Air
Moisture meter readings of an elevated moisture content of the
wall material make it a candidate for this type of testing, especially when it
is drywall (the paper covering is vulnerable to consumption from mold growth).
Samples are collected using the WallChek ® system, providing an adapter for an
Air-O-Cell ® cassette, and utilizing a small ¼ inch tubing, which is inserted
into the wall. Air sampling pumps set at 15 liters per minute (lpm) draw air
from the wall cavity for, normally, two minutes, for a total of 30 liters.
Here we use a swab or tape.
Carpet samples are collected with a system called DustChek ®,
developed as a sampling and analysis technology for the enumeration and
identification of both total and viable fungal spores in dust. The system
involves sweeping carpeting with a vacuum that has a DustChek ® assembly
attached. The collected dust can be analyzed for total and viable fungal
spores, as well as allergens. After the collection is complete, the DustChek ® receptacle
is securely capped to prevent external contamination.
Small Pieces of Contaminated Material
Sometimes it is necessary to remove
a small portion of the material affected (e.g., wall board, insulation,
etc.). These are collected without marring appearances, whenever possible.
Water From Condensate Drain Pans or Cooling
This can be an indicator of contamination at the water source.
After the collection procedure is accomplished, we'll
confer with you concerning which samples should be microscopically examined
by a certified laboratory, allowing us to determine the genus of the
mold sampled. This is necessary because unmagnified appearances may not
be reliable indicators. While certain colors may suggest the presence
of a toxic mold (for example, the purple and green sheen sometimes associated
with Stachybotrys sp.), varieties may not always exhibit the same colors.
Black mold, white mold, green mold, etc., all require scrutiny along
with scientific methodology to ascertain if the sampled mold is a genus
known to produce mycotoxins.
You pay an analysis fee only for the samples sent to the
laboratory. There is no charge for those not sent. Those
not sent will be placed in a special culturing area. Their
mold growth progress will be noted visually, and
For those samples chosen for the laboratory, a "chain of
custody" form is completed by our field representative and
the specimens media is carefully packaged and sent. Three
days after the laboratory receives the samples, their
microscopy technician will send Toxic Consulting a written
report, which is immediately forwarded to you.
The specimens analysis report (an example can be seen
here) is interpreted for you, following industry-standard analytical
methods. The report includes quantitative findings for each of the following
fungal spore varieties:
- conidia, unidentified

You also receive the added
benefit of a unique written compilation of all procedures
and findings. Investigative methods, laboratory results,
and your field representative's recommendations are
documented in a comprehensive report averaging eighteen
pages in length. Because of the proprietary nature of the
report the preview is limited to the Table of Contents .
