Mold what is it?
Molds can be found almost anywhere; they can grow on virtually any organic substance, as long as moisture and oxygen are
present. There are molds that can grow on wood, paper, carpet, foods, and insulation. When excessive moisture accumulates in
buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains undiscovered or
Some of the more common indoor molds are Penicillium, Aspergillus, Cladosporium and Alternaria.
Many types of molds exist. All molds have the potential to cause health effects. Molds can produce allergens that can trigger
allergic reactions or even asthma attacks in people allergic to mold. Others are known to produce potent toxins and/or irritants.
Potential health concerns are an important reason to prevent mold growth and to remediate/clean up any existing indoor mold

When do you test for mold?
Lawyers/Doctors:There may be some situations where mold testing (air and or surface) may be necessary: for instance, you are
involved in litigation and your lawyer wants to have the molds identified, or someone in the house is sick and the family physician
has asked for mold tests or mold investigation,
Building Owners: Additional reason your house or office might need mold testing, building health is one of them. Unusually high
mold spore count indicates structural damage or hidden water leak or condensation.In a few cases, mold is strongly suspected but
is not seen and you are not prepared to start taking walls down. The moldy odour may also be occasional and you are unsure
whether mold is a problem. Testing the air may be justified.
During an Inspection: There are times when a surface sample is a good idea, such as when the inspector identifies a red flag,
such as stains which may or may not resemble mold and you the buyer, during a home purchase, may need to understand what
your next step will be, such as, provide 3rd party laboratory proof that it is indeed mold to renegotiate, back out of a deal or
arrange to have it remediated (removed). An example I have come across would be insulation in the basement appears to be
black, a sample would be taken and sent to a certified laboratory.
Real Estate Agents (for a pre-listing inspection): Some real estate agents looking to list a property will have me do a
pre-listing or maintenance inspection. If suspected mold is found they want it tested for conclusive proof as to what it is. This way
they can show the owner and decide what the next step would be.
Building/Property Managers - The building/property owner has asked me to come in and do a Complete Mold Inspection to
document the condition of the property prior to rental.
Renters/Tenants: May require a mold inspection (complete or limited) or specific area sampling to provide proof to the landlord
During a property inspection, inspectors cannot be conclusive that a stain is indeed mold, even if you feel it is. A 3rd party test
SHOULD be performed to be conclusive for the record.
Some common areas where mold can be found, but definitely not limited to; inside cold cellars, basement walls, behind insulation,
below or around laundry tubs, ceilings below washrooms, ceilings in garages and one of the most common areas inside attics.
How do you remove mold?
Depending on the amount/size of infected area, as well, where it's
located will determine the type of removal or remediation. Some
more popular ways are as follows:
1. Temporary Encapsulators or Painting - these methods may
use chemicals, will they last? hard to say. Is this method safe in all
locations such as an attic and are there any indoor air quality
issues with chemicals?Attics can become very hot in summer time.
2. Blasting - A method which blasts the mold off of the surface,
removing a portion of the surface but may not eliminate all of the
mold and may also blow the mold particles into other areas.
3. Replacing or Removing Areas - Depending on the infected
area, such as an attic, you may remove and replace the sheathing
but how about the rafters and insulation?
4. Bleach or some other Chemical - Mold can be found on wood
or other porous material - will the use of chemicals clean all the
areas, maybe, but you may only remove the surface areas how
about deep down into the material? Also chemicals may not be the
best for indoor air quality.
Do you need to test for mold?
Canada Mortgage and Housing Corporation (CMHC), the U.S. Environmental
Protection Agency(EPA) and the American Industrial Hygiene Association (AIHA)
do not recommend testing the air for molds in single-family dwellings and similar
buildings as a first step. The recommended first step is having a trained
investigator check your house for mold.
Please understand there are NO EPA or other federal limits which have been set
for mold or mold spores, sampling cannot be used to check a building's
compliance with federal mold standards. As well, air sampling can only provide a
snap shot in time where mold levels can vary widely at different times and days.
A thorough investigation based on building-science principles and experience is
more helpful than testing the air. An air sample test does not pinpoint sources of
moisture, tell you why you have a mold problem or suggest ways to fix it. A trained
investigator determines causes and suggests ways to remediate and improve
potential problems. A properly trained investigator who follows a Certified Mold
Investigation Procedure/Guidelines (such as IAC2/InterNachi) or Indoor Air Quality
Guideline (such as InterNachi and or CMHC) provides you with a written report
that includes recommendations.
Types of Mold Testing - Viable and Non-Viable
Viable or culturable sampling refers to collecting mold spores using a method that allows the spores to grow. The laboratory
analyzes the samples while they are living and growing, and this allows the laboratory to accurately determine the exact type of
species and genus. Generally used if a doctor needs to understand the family and species or maybe in litigation.
It takes longer than non-viable testing, since seven days of culturing is required. Viable testing may not identify dead mold spores
or fragmented parts of hyphae, which may cause health problems or allergic symptoms. Viable testing can be expensive.
Non-Viable - Mold inspectors typically use non-viable sampling in their inspections. The most popular and least costly method
A non-viable sample is directly examined under a microscope. The mold spores are identified and counted. Other particulates are
examined and identified based on a sample's physical features, such as fibers, skin cells, and hyphae fragments. The spores
alone cannot identify some molds, such as Aspergillus and Penicillium. These are reported as a group in, for example, the
Aspergillus/Penicillium group or the Periconial/Myxomycetes group. When you just need to know if it's mold.
Asbestos refers to a group of naturally occurring fibrous minerals that have the ability to resist heat, fire and electricity.
Although asbestos fibers are microscopic in nature, they are extremely durable and resistant to fire and most chemical reactions
and breakdowns. These properties of asbestos supported its use for many years in a number of different commercial and
industrial settings, as well as in a wide range of consumer products. Although its use has diminished in recent decades, there
are still many products that contain asbestos, especially in older homes, schools, and public buildings.
Health Issues related to Asbestos
Asbestos is made up of microscopic fibers that can easily become airborne and inhaled. Because of their shape, the asbestos
particles cling to tissues of the lungs and other areas of the respiratory system. Over time, these tiny fibers can cause
inflammation, causing a number of health problems, the three biggest of which are:
1.Mesothelioma — This aggressive cancer forms in the thin membrane (mesothelium) that protects vital organs in the chest and
abdomen. Exposure to asbestos is the only medically-verified cause of the disease.
2.Lung Cancer — Most commonly associated with factors like smoking and radon, lung cancer is also known to be exacerbated
by exposure to asbestos.
3.Asbestosis — This degenerative respiratory condition results from the formation of scar tissue plaques on the surface of the
pleura (lung linings). It can be a precursor to the onset of mesothelioma.
More information can be found at the Mesothelioma.com website.
Who is at Risk?
Because asbestos was used in thousands of commercial products up until approx 1980's and in some cases until 1990 and in
several industries, exposure to Asbestos was common in a long list of trades and occupations. Exposure may also be of concern
if you happen to work or go to school where asbestos products, especially friable type of asbestos, is still found. Friable is a term
given to a material which can easily be broken up (by hand, or mechanical damage) exposing particles of the material, some of
which may be asbestos.
Where can Asbestos be found?
Some of the more common areas asbestos may be found would be;
Exterior Building Material - cement siding, cement roof panels, loose fill insulation (Vermiculite)
Floor Finishes - Vinyl asbestos tiles, sheet vinyl flooring, floor leveling compound, linoleum flooring, mastic
Ceiling Structures - lay-in and stick up ceiling tiles, acoustic and stucco sprayed, plaster or drywall jointing material
Walls - plaster or drywall jointing materials, sprayed fireproofing, asbestos transite panels
Mechanical and Fan Rooms - insulation on boiler pipes, vessels, ducts, walls, ceilings, around furnaces and furnace plenums.
Mechanical Pipe Systems - steam and hot water heating supply and return lines, insulated pipes.
Literally 1000's of products contained Asbestos - Residential and Commercial Construction, the list is extensive:

Why should you care?
In Canada there are strict requirements for renovating, remodeling or even demolishing a building constructed prior to 1980 and
in some cases in some building constructed after 1980. You can't just go in and demolish or renovate an older building this may
disturb and release material which may contain asbestos, possibly harming the workers and or employees. Ontario Regulation
278/05 has put into place specific removal guidelines to help protect people. As a building owner/corporation you may be fined.
Why test for Asbestos?
As a home owner you may or may not be subject to the Ontario Regulation 278/05, however understanding what your property
may contain is important for you and your family's health, especially if you intend to renovate or remodel. The contractors you
hire may also need to understand what they are working with. Identifying possible asbestos containing material is a start, then a
laboratory test should be done to confirm. There are so many variations of material which may or may not contain asbestos
which is virtually impossible to tell by just looking at it. Testing is the only conclusive way.
When do you test for Asbestos?
Testing for asbestos should be done on homes or buildings built prior to 1980. Also if you intend to do any remodeling or
renovations. In some cases, if you do not disturbed the material and it is not friable then you may be able to leave it alone and or
encapsulate (sealing the material) it, this should only be determined after it has been examined and tested by a professional.
Testing should also be done on homes prior to selling so there are no surprises.
How can we help?
Do you have Vermiculite (a type of insulation in the attic which may contain asbestos). Maybe a material wrapped around the
boiler pipes and or heat registers. Ceiling or floor tiles in basements that haven't been renovated since the 1970-1980's.
Samples should be taken and tested to make sure the buyer and or seller understand if the material contains asbestos. This
way you can move the deal forward, renegotiate or back out. Keep in mind the cost to remove (remediate) Asbestos containing
material can be expensive.
