How Common Is Mold In Buildings

How to search for hidden mold in your home

Molds are very common in buildings and homes. Mold will grow in places with a lot of moisture, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.

The most common indoor molds are Cladosporium, Penicillium, and Aspergillus. We do not have precise information about how often different molds are found in buildings and homes.

How Does Mold Get Into Our Homes

The more people who live in a home, the more likely it is that molds will grow inside it. This is because we release a lot of moisture in the air when we breathe. When we take long hot showers, cook with uncovered pots, dry clothes on an indoor clothesline, or use humidifiers, we also make more moisture for molds to grow. Storing wet firewood, watering many plants, and storing many vegetables like potatoes and squash can make a mold problem more likely, too.

Mold Is Often A Sign That You Have A Bigger Problem

If you spot mold in your home, its often a sign that you have a water leak or plumbing issue that needs attention. Some species of mold also give off a musty odor, which is a telltale sign that youve got a bigger problem to address.

Mold is also a big concern in areas that have been impacted by significant storms and flooding. For example, mold formed in many buildings in New Orleans after Hurricane Katrina.

Dont Leave Wet Stuff Laying Around

Anyone who has young children knows how much water ends up on the floor during bathtime. Its safe to assume that the bathmat is soaked, and you may have a couple of wet towels leftover too. Dont leave these lying around! As soon as youre done using them, get them off the floor and hang them on a towel rack or over the shower rod to dry.

If you have older children, regularly check their rooms for wet towels and clothing. Even something as simple as a sweaty soccer jersey can grow mold if its left to its own devices. Although it may not seem like its worth the argument that ensues every time you ask your teenager to pick up their room, we promise its worth it in the long run.

Mold Prevention And Removal

The best way to prevent mold is to remove water and moisture sources. Fix leaks, dry damp areas and remove humidity from the air to help stop mold growth and keep it from coming back.

To remove mold:

  • Seal off moldy areas using a plastic sheet and duct tape until cleaned. Keep children and pets away.
  • Use water and soap to clean small areas of mold on walls or other hard surfaces when you see it. Wear waterproof gloves while cleaning.
  • Dry the cleaned area completely.
  • Clean any visible dust from work areas. Use wet mops or HEPA vacuums.
  • Throw away all cleaning-related waste in heavy-duty plastic bags and seal securely.
  • If the mold returns quickly or spreads, there may be an underlying problem, such as a water leak. Report repeated mold problems to your landlord.

    If large areas of mold are present, you may need outside help such as a professional mold abatement company. Be sure your contractor is licensed and follows NYS Labor Law requirements.

    To report a large amount of mold in an apartment if you are a tenant, or if the mold is in a non-residential location, submit a complaint online or call 311.

Many small patches of mould in one area or throughout your home are a sign of moisture problems that need to be investigated and corrected right away.

    If ignored, small mould areas may become larger over time, so it is important to clean them up before the problem gets bigger. A small amount of mould may be cleaned up using proper procedures and protective equipment.

    The area of mould is considered medium if there are more than three patches of mould , but the total area is less than three square metres. In this case, assessment by a qualified professional is recommended but in most cases a medium amount of mould may be cleaned up using proper procedures and protective equipment .

    An area of mould is considered large if a single patch of mould is larger than three square metres. Health Canada does not recommend that an unqualified person clean up large areas of mould. You may need a professional assessment to determine why the mould is there in the first place and how to clean it up.

    Tips For Mold Prevention

    How to know if you have mold in your home

    Wondering how you can prevent mold from affecting your home? Here are a few tips that may help you prevent mold from forming altogether.

  • Keep things clean Dirty surfaces can provide mold with the organic food materials they need to take hold, and start growing throughout your home. Be particularly careful in areas which may be damp, such as kitchens, bathrooms, and attics.
  • Address dampness Dampness may be an issue if you live in an area which receives a lot of rain, or your basement floods. Make sure to ventilate your home as much as possible in humid climates, and soak up any visible moisture as soon as possible.
  • Keep the air dry Air conditioners and dehumidifiers can help reduce the moisture content of the air. Keep your air at 40-50% relative humidity for the best comfort, and to prevent the growth of mold.
  • Heat damp areas to dry them out You may consider using space heaters or even a hair dryer to heat damp areas of your home where mold may form. This is a short-term fix, though. Its best to address the source of the dampness, not the dampness itself.
  • Keep the air circulating Proper ventilation from attics, bathrooms, kitchens, laundry rooms, basements and any other place where moisture is common is essential. Make sure that your home is properly insulated and ventilated, so that air can circulate properly

    Why Does Mold Form In Homes

    Mold forms in homes because, in many cases, a home is the ideal place for mold to grow particularly in basements and other areas which may be dark and moist, and have a similar temperature all-year-round, due to furnaces and water heaters.

    Essentially, there are mold spores in the air at all times and once they find a place thats hospitable to them, theyll start reproducing, causing a visible mold problem.

    How Do I Look For Mold

    There should be two goals when finding mold: getting rid of the mold, and finding the water or moisture that is creating the mold in the first place to fix the problem at the source. Hiring a professional mold inspector is always the best bet to know for sure, but doing occasional mold inspections on your own is a great way to prevent large colonies from growing.

    To look for mold on your own:

    • Wear goggles, gloves, and a mask to ensure your safety against any mold mycotoxins
    • Look for wet spots, or spots that are frequently humid or damp
    • Using a flashlight, inspect the area for any discoloration, textured patches, or signs of growth
    • Pay attention to any strange smells that feel musty or moldy in any way
    • If you find a spot that looks suspicious, and might just be dirt, inspect it more closely but be careful to cause minimum disturbance in case it is mold that can release spores when disturbed

    What Is Mold And What Causes Mold In Your Home

    Mold is, by broad definition, a type of fungus that sprouts from microscopic spores floating in the air. When clusters of mold spores grow on surfaces, they start to reproduce and become visible to the human eye. If you have mold allergies, asthma, or another lung condition, even breathing in the microscopic pores can trigger an attack. If you dont, you may not even be aware that there is mold in your home until you see it or smell it .

    All homes have the key ingredients needed for mold growth: the presence of mold spores, a surface for it to grow on, oxygen, warmth, and darkness. When you add moisture, whether from a water leak, stagnant water, or high levels of humidity, into the mix, thats where mold problems begin. Knowing where mold is commonly found in homes can help you prevent and treat it so you can keep your home and body healthy.
