Mould Inspection  – When is it Necessary to Test For Mold?

Despite indoor mould being one of the most common problems in residential properties in Canada, there are not any widely accepted methodologies for its measurement. The Barrie Home Inspector has taken Level One Mould Course and has the latest equipment for indoor Air Quality Testing.  All our Air Quality Samples are sent to Pro-Lab for testing. Symtoms of mould are constant health concerns such as: coughing, sneezing, cold or flu symptoms. It can also irritate the eyes, skin, nose, and throat. For those with serious mould allergies it can lead to shortness of breath or difficulty breathing, while people with asthma may have asthma attacks.

Our indoor environment tends to be more polluted than the outdoor air. Poor-quality indoor air can cause major health problems, such as allergies and respiratory diseases. And even minor ailments, such as headaches and eye irritation.  Part of our Air Quality Testing involves taking an Outdoor Air Sample that the laboratory can use as a Baseline when testing areas inside your home.

Mold Inspection – Testing (Sampling)

Mold testing is the actual collecting of samples for laboratory analysis. There are four types of sampling methods used in a standard mold inspection; surface samples, bulk samples, air samples and innerAir Quality Testing Equipment used by Barrie Home inspector wall samples.

We recommend testing your home for mold if:


✅  You smell a musty odor in the home (a musty odor is almost always caused by some sort of mold).

✅  Your home has recently been flooded (mold frequently begins to grow after a home has been flooded).

✅  You discover mold in one area of the home (mold spreads quickly and easily throughout a home, so if you have mold in one part of the home, we recommend testing the rest of the home in case the mold has spread).

✅  You or another member of your household have symptoms of mold-related health problems, such as chronic sinus infections, chronic sore throats, frequent headaches, coughing, wheezing, unexplained rashes or hives, or unexplained fatigue.

✅  You may also want to have your home tested for mold if you or another member of your household has a health condition that can be made worse by exposure to mold, such as asthma, severe environmental allergies, respiratory disorders, or immune system disorders.

✅  You suspect there is hidden mold in your home that you can’t find.
