Visual Inspection: A visual inspection is the initial step in identifying possible contamination problems. It will identify any visible water leaks or moisture stains on ceilings, walls, floors or under counters. The air conditioning and heating systems, the attic and crawl spaces under homes will receive a visual inspection as well. The use of equipment such as a boroscope to view spaces in duct work or behind walls, and
moisture meters are used to help identify hidden sources of mold growth and the extent of the water damage. Mold sampling will be recommended if there is any noticeable mold growth, musty odors, visible water damage or stains, poorly maintained HVAC systems or construction defects. By combining a visual
inspection with air, tape or swab sampling the inspector can help identify the hidden source of mold, allergens and indoor pollutants and the extent of any acute or chronic water or moisture damage.


Air Sampling: The purpose of air sampling is to determine the type and amount of airborne contamination in a building. Air sampling may be necessary if the presence of mold, allergens or toxins is suspected (e.g. musty odors, allergies) because it cannot be identified by a visual inspection. When air sampling is performed, both the indoor and the outdoor air are sampled, so the results can be compared to see if a problem exists. Typically the indoor sample is taken while the heating or air conditioning unit is operating, this will ensure the interior air is effectively tested.


Tape/Swab Sampling: Tape/Swab samples are usually collected from visually moldy surfaces by wiping the area with a sterile swab. This type of sampling is used to identify specific mold types.


Recommendations and Laboratory Results: Once the home has a visual inspection and the mold circumstances are evaluated, action can be planned to clean it up and prevent future contamination. Based upon site evaluations and sampling lab analysis results, your inspector can provide a detailed written report that can be used for disclosure and references. In all situations, if mold exists, the underlying cause of the water damage must be corrected.

How can household Mold be reduced?  

    It is impossible to completely eliminate all mold and mold spores indoors. Mold will always be found floating in the air and in house dust. Indoor mold growth can be prevented by controlling water and
moisture indoors. The following may prevent or reduce indoor mold growth. 

  • Repair any water leaks

  • Provide good air circulation 
  • All HVAC systems should have a good electrostatic filter on the return
  • Use bathroom, kitchen and laundry room exhaust fans 

  • Insulate and ventilate attic and crawl space areas

  • Clean, dry or remove items that are damaged by water immediately

Real Estate Deals DO NOT Need To Be Broken!


    If the home you are thinking about purchasing has mold, do not panic! You can remove unusual mold levels from the home, and bring it back to the original condition.


NOTE:  If there is mold growth in your home, you must clean up the mold and fix the water problem. If you clean the mold but do not fix the water problem, the mold will grow back. If the contaminated area involved is very large, you may want to consider hiring a professional. 


Clearance Testing: The most important part of the remediation (Clean Up Process) is the clearance testing. This final testing procedure provides confirmation that the project has been satisfactorily remediated and that the contamination has not spread to other areas. 


    Since there has been so much media hype surrounding mold, prospective home buyers want a home that has been mold inspected. Mold sampling has become a standard practice during a home inspection. You should not buy a home with mold, sell a home with mold or live in a home with mold. A mold inspection is your first line of defence!


    To find out if mold is a problem in your home, you MUST have a mold inspection conducted by your inspector.

Where is Mold found in the home?

    Mold can be found in several areas in the home environment. It appears most often in moist areas as little black circles or thread-like white objects. It is usually accompanied with a musty-type odor. Outdoors, mold plays a natural part in the environment by breaking down dead organic matter such as dead trees or fallen leaves. Mold reproduces by means of microscopic spores; the spores are
invisible to the naked eye and float through indoor and outdoor air. Mold begins to grow indoors when mold spores lands on surfaces that are wet or damp.  Mold will not grow without water
or moisture. Therefore, it is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth.


Some examples of places where mold can be found inside the home include:

  • Basements, kitchens (bottom of fridge), around bathroom vanities, washer/dryer area

  • The underside of carpets and pads

  • The surface of walls behind furniture (where condensation forms)

  • Ceilings and the top side of ceiling tiles

  • Front and back side of drywall, wallpaper or paneling

  • Inside HVAC systems and duct work

  • Clothing

  • Food

With exposure, even in small amounts, mold may cause:

  • Minor itching or irritation of the nose, eyes, throat or skin

  • Mysterious skin rashes

  • Sinus infections or congestion/sinusitis (runny nose)

  • Respiratory problems (sneezing and coughing)

  • Upper or lower respiratory infections

  • Fatigue

  • Frequent headaches

  • Trouble concentrating, memory lapses, confusion

  • Mood swings, anxiety, depression

  • Chronic aches and pains

  • Digestive problems

     Mold... literally a growing concern. National media attention has alerted the public to the destructive and possibly toxic dangers of hidden mold spores that could affect their family's health and home. Health Canada studies indicate that air levels of indoor pollutants may be two or three times higher than outdoor levels. Mold, the most dangerous offender of all, often goes undetected because of its invisibility. Most people spend as much as 90% of their time indoors and are not aware of the health hazards created by this pollutant. You owe it to yourself to minimize your exposure to mold spores in the indoor environment. Test for mold today!


How can someone be exposed to Mold?

There are several ways you can become exposed to mold:

  • Breathing in the spores from the air

  • Skin contact from handling an item that has mold growing on it

  • Eating without properly washing your hands after handling moldy objects


Can Mold cause health problems?

     Mold has the potential to cause health problems and even make a home uninhabitable. However, everyone is affected differently when in contact with mold. The mold that may not bother the seller may severely affect the buyer. Some mold can produce allergens, irritants and, in some cases, potentially toxic chemical substances known as mycotoxins. People diagnosed with allergies and asthma may be very sensitive to mold. Mold can cause asthma attacks. Others at risk may include: infants, children, the elderly, pregnant women and individuals with existing respiratory conditions.
