How To Tell If I Have Mold In My Basement

Top Warning Signs Of Mold In The Home

How do I know if I have mold?

Here are some of the top warning signs that you may have a mold infestation that requires basement waterproofing or foundation repair.

  • A damp or musty smell. If you smell a damp, musty, or earthy odor, you might have a mold problem. Thats because mold secretes a pungent odor, and its one of the biggest giveaways that mold is taking hold in your home. Yet, some homeowners are so used to the smell that they arent even aware of it. If you are unsure, ask a friend or family member to stop by and sniff for themselves.
  • Black spots or stains. Mold often appears as dark spots or stains on walls and insulation. But there are many types of mold which look very different from gray or green furry tufts to white streaks to colorful splotches of orange, pink, or purple.
  • Peeling wallpaper or paint. If you see bubbling, cracking, or peeling in wallpaper, it means moisture has gotten under the paper and weakened the glue. Mold loves to grow in these damp pockets, hiding just out of sight.
  • Damp, humid basement. Basements are a prime breeding ground for mold. Thats because they are usually colder than other rooms in a home, and cool temperatures create condensation. In addition, cracks in the foundation can allow water to enter and provide a place for mold to grow.
  • Condensation on windows and pipes. Mold thrives in areas where condensation creates moisture.
  • How To Tackle Mold

    Now that weve covered how to identify mold, lets talk about what you can do to get a handle on the situation.

    What Causes Mold To Grow In Basements

    Mold loves temperatures between 60 and 80 degrees F, a little bit of moisture, some tasty surfaces to feed on, and plenty of room to growall of which the average basement supplies readily.

    You can have issues with mold after a small leak, say, from a water heater or bathroom, rain coming in a basement window after a big storm, a major flood event, an overwatered plant pot, or even just due to an excess of indoor humidity.

    Yes, the sheet rock should be removed. This is necessary not only to clean up the existing mold, but to implement the prevention measures.

    First, you need to identify the source of the moisture. Three possibilities exist. 1.) Condensation from the warm interior air hitting the cold concrete wall. This typically does not happen behind a well sealed wall , but its possible.

    2.) Vapor emissions through the concrete. This occurs when moisture moves through the concrete in vapor form, creating high humidity and saturation on the surface. In an uncovered wall, the water would simply evaporate into the air without causing an issue. The installation of the sheet rock traps the moisture, leading to mold growth. There are two solutions either keep the concrete exposed or install dimple board with a interior footing drain.

    3.) Liquid water intrusion. Its possible youre having liquid water enter through the cold joint at the bottom of the wall. If this is the case, youll see more damage at the bottom plate/framing than higher up the studs. In most cases, the solution is an interior footing drain.

    Common Causes Of Basement Mold

    Every basement is different. It all depends on what they are used for. Some are used for excess food storage and might have an extra refrigerator or large freezer.

    Others are partially finished meaning there may be space that is used as a living space, and other parts that are like an old basement .

    Other basements are finished with carpet, drywall, and paint. Any of these types of basements are subject to mold.

    Since most basements are constructed using cinder blocks, moisture can seep into the blocks if not treated properly. When a basement is built, there should be a weather-proofing material added to the outside before the dirt is put back in place.

    The material can include a tar-like substance that is painted onto the outside of the bricks. Some companies might add in an extra layer of plastic or tarping.

    The materials aid in reducing moisture from getting into the blocks or bricks. If moisture does seep in, it can lead to a buildup and require basement mold removal.

    In a finished basement, the moisture can build up behind the walls or under the flooring and take a long time to be noticed. When this happens, and the mold is not visible, it is usually noticed due to odor.

    Most basements have a musty odor anyways, but a finished basement should remain dry and moisture-free, meaning no musty odors. If you have a finished basement and notice a musty odor, it is recommended to contact a basement mold removal technician to assess the situation.

    • Sponge: On softer or smoother surfaces, a disposable sponge may be all thats needed to stop mold spots from becoming more significant problems.

    Your basement can be a great extension of your homes livable space, but its also not one that many people effectively use, often because its damp or has a funny smell. But it doesnt have to be this way – many homeowners think the musty basement smell is a natural part of their basement, but its actually a warning sign that you likely have mold growing.

    If you think there may be mold in my basement, the good news is that mold is both preventable and can be thoroughly eradicated.

Theyre used for storing things that make excellent dinner for mold spores, and they often have moisture to kickstart and supply mold growth. If any of this sounds familiar, the mold specialists at MoldTech can help you assess any potential mold issues and offer suggestions to help remediate the problem.

    Common Types Of House Mold

    Wondering what types of mold are the most common in houses and which ones you should be concerned about? Lets discuss a few of the most common types of household mold now.

    • Cladosporium Cladosporium is one of the most common household molds. It usually grows in a greenish-brown colony, but can also be nearly black in color. It is rarely harmful unless you have a mold allergy, but may cause minor issues like toenail or fingernail infections.
    • Penicillium Penicillium is sometimes called green mold, as it is usually dark green in color. It tends to grow in large, consistent patches on the walls. As the name suggests, penicillin is derived from some kinds of this mold. However, some kinds of penicillium mold may be toxic to humans and animals.
    • Aspergillus This type of mold is usually greenish-white in color, and may be more raised with a more cloudy appearance than other types of mold. It is not harmful, unless you have a weakened immune system, in which case it could infect the lungs or sinuses.
    • Alternaria Alternaria mold is usually greenish-white, but can also appear in black patches, so its sometimes confused with black mold. Alternaria can be a factor in exacerbating asthma, particularly for those who may have mold allergies.
