    How To Choose A Mold Inspector

    • Compare several different companies near your house for price and services.
    • Ask friends and family for referrals to inspection companies they have used.
    • Ask the company near you for recent referrals. Take the time to call these prior customers to find out how their experience was and if they would use the service again.
    • Make sure that a written evaluation is provided that specifically states the areas of the house that were inspected, the cause of the mold, the extent of the growth, how the problem can be fixed, and an approximate cost.
    • Make sure that the laboratories that are being used to analyze the mould samples are accredited by either the American Industrial Hygiene Association or by the EPA.

    Of course one of the most obvious ways to determine that you have mold in your house is if you can see it. The downside? If you see a ton of visible mold, it can be an indicator that you have a big problem on your hands.

    “Once you see it, you’ve got a big mold problem because what you’re seeing is literally just the tip of the iceberg,” Kelly Hayes-Raitt, a housesitter and the former director of the HomeSafe Campaign in California, told INSIDER.

    Simply scrubbing the visible mold with soap and a sponge won’t actually get rid of the mold. So if you see visible mold, you need to reach out to a mold remediation company or another expert to help you get things under control, including any leaks that may have caused the issue in the first place.

    The most common and reliable way to test for mold spores in the air is through non-viable air sampling. This is also called a spore trap analysis.

    A trained indoor environmental professional will collect samples of air, using a calibrated air pump. The air will be collected onto non-viable mediums, called cassettes.

    The microscopic airborne spores get pulled into these cassettes, which have an adhesively coated glass slide medium. As mold spores enter in, they become impacted into the glass slide medium.

    The cassettes are then delivered and microscopically analyzed by a trained environmental microscopist or mycologist at an accredited laboratory.

    Air Quality Testing For Mold

    Most people are not aware of how severely mold can affect their health. Because mold spores are so small, they can become airborne easily and spread quickly. Just because you cannot see a mold contamination in your home doesnt mean that its not there.

    Mold and mildew are the result of moisture and water damage. Rooms that are prone to leaks, condensation and flooding often experience mold growth. These include bathrooms, attics and basements.

    Property owners have to be careful because moisture problems are not always obvious or visible. They can remain completely hidden from sight . If left untreated, they will lead to black mold contamination.

    Exposure to black mold can cause or aggravate health conditions like asthma and allergies.

    Over time, it can also lead to more serious conditions such as chronic bronchitis, problems with the nervous system, cancer and heart conditions.

    Luckily, you have two types of air tests to help you detect unseen mold: viable sampling and non-viable sampling. Each has its advantages and drawbacks , but both are effective means of assessing indoor air quality.

    Health Effects Of Black Mold

    According to the EPA, various types of mold can cause health problems for some people. Those health problems are primarily in the form of allergies such as stuffy head, headache, itchy eyes, trouble breathing, etc. These ailments can be more severe in the young, the old, and those with other health issues. The CDC basically says the same thing that mold can cause health issues in some people, or no issues in other people.

    According to the CDC, Stachybotrys black mold is unproven to cause serious medical issues beyond those mentioned above. In other words, symptoms of black mold are only proven to be similar to other molds. The CDC simply states that various types of mold may cause health symptoms, to consult with a doctor if symptoms persist, and that no color or type of mold belongs in a building.

    You may be thinking: If all we know for sure is that mold causes allergies in some people, and maybe some serious health problems in a small percentage of other people, then whats the big deal?

    Well, our answer to that is to imagine yourself as one of those people who are sensitive to mold. Constant allergies, constantly feeling sick, and miserable in your own home. Theres even a scientific name for it: Sick Building Syndrome . Mold, along with other problems such as radon, Chinese drywall, etc., can cause Sick Building Syndrome.
