    How To Identify Mold Vs Mildew In Your Home

    • Email

    Mold and mildew are often spoken of together, almost as if they were the same substance. We fear mold and mildew growing below our homes in crawl spaces, under house siding, around the bathroom wall surround, and behind the sink. Excessive, pervasive mold and mildew can hamper a house sale or cause homeowners to move their bedroom elsewhere. Neither mold nor mildew is welcomed in the home, in any form.

    Though related, mold and mildew are separate microorganisms that grow differently and must be treated differently. Safely eradicating mold and mildew is crucial to keeping you safe and your home in good shape.

    You Visibly See Mold Spores

    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.

    How Do Molds Affect People

    Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions. Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay. Severe reactions may include fever and shortness of breath.

    In 2004 the Institute of Medicine found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people with asthma symptoms in people with asthma and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.

    In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould pdf iconexternal icon pdf icon. Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies.

    Getting Rid Of Basement Mold

    Mold in the basement can be persistent, given the nature of basements they tend to be much more humid than above-ground levels and typically have poor ventilation and little air flow, a combination that can cause mold to flourish. And of course, basements can be prone to flooding, due to extreme weather or undetected leaks in the pipes or sump pump. In addition, once mold develops, cinder blocks or concrete walls can be difficult to clean due to their rough texture.

    To get rid of mold in the basement, scrub the walls using a large brush, and keep in mind that porous surfaces such as ceiling tiles or drywall might need to be removed and replaced. If basement carpet has become moldy, sweep it to loosen the mold and let it dry in the sun if you can move it, or use high-powered fans to remove moisture if its affixed to the floor.

    To prevent mold in the basement, you need to alter the conditions that can cause it to grow. First, remove dampness by installing a dehumidifier and making sure the dryer vent exhausts externally, if you use your basement for laundry. Then turn your attention outside: Shore up cracks and other foundation issues, and make sure that your soil is properly graded so that rainwater or melting snow goes away from the house, rather than collecting near your foundation.

    Are There Visible Signs Of Mold

    Mold leaves behind clues, especially if there is enough of it. One of the clues is the visibility of mold growth. Mold can discolor your walls and spread quickly. Even if the mold has been painted over, it will often show itself over time. If there are visible signs of mold, the chances are good that the mold is deep in your drywall. Some surface mold can be cleaned, but if the mold is inside the wall, it will need to be replaced. Perform a detailed inspection of your home if you suspect mold in your walls. Be sure to look at walls behind furniture and along baseboards.

    Many homeowners are worried about the potential of black mold and spend lots of money testing once visible signs of mold are found. However, much of this testing isnt necessary. While black mold is well known for the damage it can cause, all types of mold can affect your health and should be dealt with promptly and properly. Therefore, if you see visible signs of mold on your walls, you can skip the testing and simply replace and remediate.
