What
is Mold?
Molds are fungi. Molds grow and are present throughout
nature and in our living environment. Tiny particles
of mold are present in indoor and outdoor air. In
nature, molds help break down dead materials and can
be found growing on soils, foods, plant matter, and
other items, they are vital to our own existence.
Molds produce microscopic cells called "spores"
which are very tiny and spread easily through the
air. Live spores act like seeds, forming new mold
growths (colonies) when they find the right conditions.
What
does mold need to grow?
Mold only needs
a few simple things to grow and multiply:
- Moisture,
including humidity from poor ventilation.
- Nutrients,
most building materials.
- Suitable
place to grow, environments humans like to live
in.
Of
these, controlling excess moisture and humidity s
the key to preventing and stopping indoor mold growth.
Should
I be concerned about mold in my home?
Mold should not be permitted to grow and multiply
indoors. When this happens, health problems can occur
and building materials, goods and furnishings may
be damaged.
Health
Effects:
Can
mold make me and my family sick?
Mold
can affect the health of people who are exposed to
it. People are mainly exposed to mold by breathing
spores or other tiny fragments. People can also be
exposed through skin contact with mold contaminants
(for example, by touching moldy surfaces) and by swallowing
it.
The
type and severity of health effects that mold may
produce are usually difficult to predict. The risks
can vary greatly from one location to another, over
time, and from person to person.
What
symptoms might I see?
The
most common health problems caused by indoor mold
are allergy symptoms. Although other and more serious
problems can occur, people exposed to mold commonly
report problems such as:
- Nasal
and sinus congestion
- Cough
- Wheeze/breathing
difficulties
- Sore
throat
- Skin
and eye irritation
- Upper
respiratory infections (including sinus)
Are
the risks greater for some people?
There
is wide variability in how different people are affected
by indoor mold. However, the long term presence of
indoor mold growth may eventually become unhealthy
for anyone. The following types of people may be affected
more severely and sooner than others:
- Infants
and children
- Elderly
people
- Individuals
with respiratory conditions or sensitivities such
as allergies and asthma
- Persons
having weakened immune systems (for example, people
with HIV infection, chemotherapy patients, organ
transplant recipients)
Those
with special health concerns should consult a medical
professional if they feel their health is affected
by indoor mold.
Are
some molds more hazardous than others?
Some
types of mold can produce chemical compounds (called
mycotoxins) although they do not always do so. Molds
that are able to produce toxins are common. In some
circumstances, the toxins produced by indoor mold
may cause health problems. However, all indoor mold
growth is potentially harmful and should be removed
promptly, no matter what types of mold is present
or whether it can produce toxins.

Investigation:
How
do I tell if I have a mold problem?
Investigate,
don't test. The most practical way to find a mold
problem is by using your eyes to look for mold growth
and by using your nose to locate the source of a suspicious
odor. If you see mold or if there is an earthy or
musty smell, you should assume a mold problem exists.
Other clues are signs of excess moisture or the worsening
of allergy-like symptoms.
- Look
for visible mold growth (may appear cottony, velvety,
granular, or leathery and have varied colors of
white, gray, brown, black, yellow, green). Mold
often appears as discoloration, staining, or fuzzy
growth on the surface of building materials or
furnishings. When mold is visible, testing is
not recommended.
- Search
areas with noticeable mold odors.
- Look
for signs of excess moisture or water damage.
Look for water leaks, standing water, water stains,
and condensation problems. For example, do you
see any watermarks or discoloration on walls,
ceilings, carpet, woodwork or other building materials?
- Search
behind and underneath materials (carpet and pad,
wallpaper, vinyl flooring, sink cabinets), furniture,
or stored items (especially things placed near
outside walls or on cold floors). Sometimes destructive
techniques may be needed to inspect and clean
enclosed spaces where mold and moisture are hidden;
for example, opening up a wall cavity.
Should
I test for mold?
We
do not recommend testing for mold yourself. Instead,
you should simply assume there is a problem whenever
you see mold or smell mold odors. Testing should never
take the place of visual inspection and it should
never use up resources that are needed to correct
moisture problems and remove all visible growth.
Sometimes,
mold growth is hidden and difficult to locate. In
such cases, a combination of air (outdoor and indoor
air samples) and bulk (material) samples may help
determine the extent of contamination and where cleaning
is needed. However, mold testing is rarely useful
for trying to answer questions about health concerns.
We
recommend Investigation and or testing for mold if
you have allergies or a hyper sensitive immune system.
We use air sampling cassettes, they are a sampling
device designed for the rapid collection and analysis
of a wide range of airborne aerosols. These include
fungal spores, pollen, insect parts, skin cell fragments,
fibers, and inorganic particulates. Air enters the
cassette, the particles become impacted on the sampling
substrate, and the air leaves through the exit orifice.
The airflow and patented cassette housing is designed
in such a way that the particles are distributed and
deposited equally on a special glass slide contained
in the cassette housing called the "trace."
Tape
lift, bulk, and swab sampling, are techniques used
for direct examination. A direct exam allows for the
immediate determination of the presence of fungal
spores as well as what types of fungi are present.
Direct examinations should only be used to sample
visible mold growth in a contaminated area since most
surfaces collect a mixture of fungal spores that are
normally present in the environment.
We
are a professional Inspection Firm that specializes
in moisture detection, the main ingredient for mold
growth. We use many techniques for detecting moisture
intrusion including Infrared
Thermal Imaging.
