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
unresolved.

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
growth.

DASH Home Property Inspection Services can provide several different services when it comes to mold. We can provide a
Complete Mold Inspection, Limited Mold inspection, Indoor Air Quality Inspection, Mold Air/Surface Sampling During
a Property Inspection.
If you’re not sure please give us a call an inspection or sampling can be designed for your specific
situation.

We have been in business full time for over 12 years have inspected over 4000 properties and certified and experienced in the
use of thermal imaging. We are also InterNachi Certified Indoor Air Quality Inspector, IAC2 Certified Advance Mold Inspector,
CMHC Indoor Air Quality Investigator Trained.

We are 3rd party independent inspection company we
DO NOT do remediation or removal of mold, therefore we are not tied to
any company which makes its money testing AND removing the mold. We can also provide post remediation air sampling and
inspection which is independent of the remediation company and unbiased. We only use Certified Laboratory Testing Centers.
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
or owner.

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.
