A mold inspection is a non-invasive visual examination of a building to identify and report on conditions that may have led to moisture intrusion, water damage, and conditions conducive to microbial growth or actual microbial growth. If such conditions are present our mold Inspection will take samples and send them to the laboratory for analysis.

Investigating hidden mold problems can be difficult and will require caution when the investigation involves disturbing potential sites of mold growth. For example, removal of wall paper can lead to a massive release of spores if there is mold growing on the underside of the paper. If you believe you may have a hidden mold problem, consider hiring an experienced professional.

A good rule of thumb is "If you can't see it, but smell it - You need a mold inspection".

People with asthma, allergies, breathing conditions or immune suppression (such as cancer patients, organ transplant recipients, HIV) may be more sensitive to mold and mold infections.

The term "toxic mold" is not accurate. While certain molds are toxigenic, meaning they can produce toxins, the molds themselves are not toxic. Black mold is just a colour, many molds are black, and other molds that produce mycotoxins are other colours.

At Mold Test USA all inspectors are IAC2 certified. This means they have been through an extensive training class and have passed a comprehensive exam to become a certified mold inspector.

Mold Test USA only does mold testing and mold inspections, not mold clean up, or mold removal. We consider it a conflict of interest when one company does both mold testing and mold remediation. It is always best to have an independent, mold testing and mold inspection company, to assist you with your mold testing and mold inspection needs. If mold removal is needed, we can help you find the most qualified mold removal company in your area.

Why you should call for a mold and air quality evaluation

  1. Many people are adversely affected by Mold…and in many cases this is hidden and not easily seen.
  2. An inspection will evaluate your environment for sources of moisture and humidity, sometimes not easily detected without the proper equipment, and recommend ways to lower these which decreases the chance for further mold growth.
  3. An inspection and air testing can confirm the presence of elevated levels of mold spores which can be the cause of many health problems. This can be used to identify certain areas that need attention and further remediation.
  4. Should elevated levels be determined, these results can be used as a baseline for further testing after remediation and cleaning has been done to confirm a positive result.
  5. Information can be used in conjunction with your health care provider to formulate a plan for better health. Certain allergies can be lowered using specialized air filtration systems.
  6. Save your investment! Molds function is to breakdown organic matter (like a composter) the problem comes when that organic matter is your home. Damage by water intrusion and mold can rot away your home and invite insects along to help.

Mold Screen Inspection with Air Samples

This is an initial step to determining if a home has a mold problem. The Inspector will perform a visual examination of all accessible areas of the residential home which is designed to identify current or past moisture problems which may lead to mold contamination. The client is encouraged to attend the entire inspection. Air and/or surface samples will be collected utilizing state of the art equipment and sent to a laboratory for analysis. Laboratory results and written report are available in approximately 5 to 7 business days. If the report analysis reveals elevated mold readings the next step is consultation with a Certified Industrial Hygienist for remediation.

Additional Things to Do:

Humidity:  To decrease mold growth, you may also want to reduce the indoor humidity in your home to 30-60%.  You can do this by venting bathrooms, dryers, and other moisture-generating sources to the outside; using air conditioners and de-humidifiers; increasing ventilation; and using exhaust fans whenever cooking, dishwashing or cleaning.

Moisture?  Whenever part of your home gets wet, be sure and clean and completely dry any damp or wet building materials and furnishings within 24-48 hours to help prevent mold growth.  (This may mean drying out or removing sheetrock, carpet, furniture, etc).

Selling a Home?  Some property owners fear the consequences of a mold inspection before a real estate transaction. This fear is unfounded since mold inspections have become a common practice.

A properly conducted mold investigation provides an honest, independent and objective assessment, which in the event a problem is found, allows the building owner to rectify the situation and provide a clean bill of health for the building prior to sale.

Buying a Home?  A Professional Home Inspection is crucial to understanding any defects in a home.   A Mold Inspection can also be done to ensure the air quality of a new environment as your family moves in.  Your Home Inspector should be able to assist you in determining if a Mold Inspection should be done in addition to your standard Home Inspection.  This may depend on what is seen during the standard home inspection or any specific health concerns you might have for your family.

The most important part of a mould inspection is often the visual assessment. (Looking for water damage, moisture, etc.) Often excess moisture in building materials can look and feel dry to the touch, but still contain sufficient moisture for mould to grow. We use thermal imaging technology and moisture meters as part of our inspection to help find any areas of moisture. We also look for other conditions around the home that are conducive to mould growth (high humidity, lot grading, foundation cracks, poor caulking and flashing, roof conditions, etc.)
Mould spores oocur naturally in the air. Air sampling can be done to help determine if mould spore levels are elevated in the indoor air, but with constantly changing conditions of moisture, humidity, weather, activity in the home, etc., a “not elevated” lab result does not mean the home has no mould.
