Home · Property Management · Latest News : Mold on the Rise: 10 Tips to Avoid Trouble in Your Property

landlord helpOver the last decade, mold has risen to become one of the most damaging toxins people face in their everyday lives.

According to USA Weekend, there has been a 300% increase in asthma over the past 20 years and with 30% of newly built homes having some form of mold, property owners need to be aware.

Mold removal is easy in small quantities, but can quickly escalate to a size and scope that can result in sickness and require expensive professional remediation to solve.

Before becoming host of the nationally syndicated home improvement radio program The Money Pit, Tom Kraeutler spent 20 years inspecting homes for mold and other maladies. Kraeutler says mold can exist virtually anywhere in the house. Whether you are inside or outside, mold spores are there. Mold spores can enter your home through openings as large as doors or windows, or as small as the tiniest gap. Once in the home, the spores can grow on clothes, shoes, toys or even pets. Worse yet, Kraeutler says, toxic mold is almost certain to release clouds of potentially harmful spores that, once airborne, can take the shortest path to your lungs.

Mold needs three things to grow: moisture, air and food – a combination found just about anywhere in a home. To keep a home mold free, Kraeutler suggests the following:

1. Mind The Moisture ” Keep humidity below 50% in basements. Improve outside grading and drainage by keeping gutters clean and soil always sloping away from the house. Cover dirt crawlspace floors with plastic to reduce moisture.

2. Store Safely ” Keep all storage several inches up off concrete floors and away from foundations where dampness can seep in. This is especially important with organic material like cardboard boxes. For a mold free home, avoid using wooden shelves; metal or plastic shelves are preferable.

3. Heat Finished Basements ” Below grade spaces like finished basements are more likely to become infested and should always be heated to at least 60 degrees, even when not being used. The warmer the space, the less the chance that condensation will form and feed a mold problem.

4. Build Mold Resistant ” Choose building materials that don’t feed mold. For example, Dens Armor Plus, is a wallboard made by Georgia Pacific that is specifically designed to prevent mold growth and would be a good choice for basement walls.

5. Ventilate Vigorously ” Poor or missing ventilation fans in damp spaces like baths and kitchens can leave enough moisture behind to sustain a mold problem. Ensure all baths and kitchens are vented by properly sized fans that take moisture outside and Not into attics. Keep the bathroom door open after bathing to speed drying of surfaces.

6. Avoid Basement Carpets” Carpets can be incredibly effective havens for mold. Even non-organic carpets can collect dirt, dust and moisture that combine to provide mold a fertile ground in which to grow, especially in below-grade spaces where relative humidity tends to be higher. Hard surface products like laminate flooring or engineered hardwoods are always a better choice for basement spaces.

7. Filter The Air ” If your home has a forced-air heating and cooling system, using a top quality air filter is a must. Look for pleated filters with a MERV rating of at least 6-8, or 11 if the family is prone to allergies. Another option is a whole house electronic air cleaner. Mounted permanently to the home’s HVAC system, it uses ionization technology to charge particles making them stick to filters like a magnet.

8. Insulate Ducts ” Duct systems that carry heated or cooled air throughout your house must be insulated whenever they pass through unheated or uncooled spaces like attics or basements. If not, condensation can form inside the ducts and when combined with dust in the air, can allow for mold to grow in the ducts, circulating spores throughout your entire home.

9. Clean Carefully ” Use mold-inhibiting cleaners in bathrooms and kitchens. Portable air conditioning units should be taken apart and cleaned at the start of every season. When painting damp spaces like kitchens and bathrooms, use paint with a mold inhibitor EPA-approved for indoor use.

10. Fix Floods Fast – For a major leak or flood, quick action can stop mold before it starts. Thoroughly dry soaked carpets and padding, and remove any wet upholstery. Then wash and disinfect all surfaces before the carpet and pad are replaced.

Mold may be a part of Mother Nature’s plans, but following these tips will ensure recovering from the mold allergies it can cause, doesn’t -become part of your plans.

    Your article on mold is imformative but there is no mention of how to kill it or what has to be done to elimate the problem. For people who cannot afford to have a mold company come in, people need to know how to kill it. I just had a friend die a week ago from extended exposure to mold. Some free information on getting rid of it could help of lot of people who don’t know what to do. Thank You

    Hi Beverly,
    We’ll do a follow up and answer your questions.

    When you have visible mold, a simple bleach/water or white vinegar/water combination can kill that particular mold, but as the article states, mold is everywhere and on every surface, no matter how much you filter or clean. What people have to be concerned about is when the mold finds its food and water source and grows to the point it becomes visible. Removing it with a mold remover or simple cleaners (like bleach or white vinegar) is easy and keep in mind, mold does not usually grow “through” drywall or plaster, it grows “on” the surfaces where its food source lies. The key is to remove the water source, just like other living organisms, no water, no life.

    Also, a previous comment states a person died from mold exposure. That is very unlikely as there is no proven death that has occurred from “ONLY” mold exposure. There usually is a significant illness that is aggravated by the allergic reaction to mold (IE: cancer/chemo treatments, lund disease, HIV positive, etc.).

    Inasmuch as Toxic Mold sounds ominous, the molds termed “toxic” were named that because of their aggressiveness toward other molds, not because of toxicity to humans. We humans just throw “toxic” around for a bit of drama.

    Simply stated, keep your house clean, avoid storing items in cardboard, keep breathing room in your closets and storage areas (no hoarding), check your plumbing and water sources and let the fresh air in and out.

    I recently had a flood and developed mold in the residence. Clean up of the mold and repairs were done. Do I need to notify new tenants of the past mold problem and or possible mold I may not be aware of? Can I give them a mold disclosure saying i’m not aware of any exsisting mold problems?
