Extensive mold in the home is dangerous. The reason is that some species of mold produce mycotoxin, a substance that leads to headaches, problems with breathing, and even damage to the neurological system.

Other symptoms may even include an annoying odor, sneezing, or a runny nose. There are other more subtle signs your home has mold. For one, a nasty smell coming from your heating system or air conditioner can mean mold. In particular, stand-alone units of air conditioning are the main spots for the growth of mold.

They are dark, damp, and frequently exposed to warmer temperatures when not in use. Putting an air conditioner in a heated closet or basement during wintertime also leads to an increased likelihood of the development of mold. 

How Do I Detect Black Mold Inside My Walls In The First Place?

• Peeling wallpaper

Peeling wallpaper can also be a symptom of mold. While some scruffiness and discoloration tend to eventually strike your wallpaper, unusual surface or peeling abnormalities such as crackling or bubbling can be a sign of wall moisture. And remember, a reliable precursor to mold is always going to be moisture. Make sure to pay attention to any warped areas that feel damp. 

To keep mold from growing in your cooling or heating systems, you can have a specialist check them regularly.

• Dark grout between bathroom tiles

Another indication of mold in the house is dark grout between bathroom tiles. Even if this type is most likely the harmless type, there could be flooding in the adjacent room or a leak in bathroom plumbing that could produce a more toxic fungus type that only professionals can remove. A sample sent for testing will let you know whether or not your shower is harmless.

Mold could also be the culprit when you have pre-existent problems with breathing that, after long periods at home, seem to flare up. Many household species of mold won’t affect persons that do not have issues with breathing. However, in individuals suffering from asthma, it could aggravate it. Consider a mold inspection and a doctor’s appointment if the problems with your breathing seem to get worse with no clear cause.

Mold can appear in many colors, textures, or shapes. They can look anything from dripping, green slime, or a grey fuzz that looks innocuous. If there are spots in your walls that are peeling away or an amazing amount of room humidity, see if there isn’t a double leak in your pipes.

• Mold reaction

Mold reaction symptoms can be as subtle as perpetual fits of sneezing or a running nose. The cold that just doesn’t seem to want to go away can be a sign of a sneaky mold issue. Notice if your cold gets worse immediately after doing laundry in the basement or when you spend time in a specific room. This is probably the room with the most abundant levels of hidden mold.

If you are suffering from endless sniffles, there might be a moldy reason for this. What you thought were seasonal allergies can be a result of mold exposure. In fact, if you go to work each day and find that your symptoms alleviate at work and get worse at home, you may have a mold infestation.

•  Humidifiers

Your humidifier may be a great part of your skincare routine, but at the same time, it could encourage mold growth. You shouldn’t have much of a problem if you use humidifiers in low settings during the dry summer or winter months. However, if you are constantly humidifying, you need to check regularly to make sure the extra humidity is not fostering the growth of mold.

Surprisingly, modern homes are just as attractive to mold as older homes. Modern homes may be more conducive to mold growth. Unlike draft, old stone homes, newly-built houses are built so tightly that damp and water spots tend to accumulate the moment it occurs inside the home rather than get vented out. Dryers, dishwashers, and modern appliances also generate the heat and moisture necessary to feed a growing colony of fungus.

• Recent Floodings

Any flooding occurrences guarantee that mold is going to come next. Most people think that a large flood in the basement leads to mold. However, even just a leaking sink pipe or a constantly overflowing bathtub creates ripe conditions for the infestation of mold.

Everyone gets affected differently by toxic mold. One sign of a possible mold reaction is feeling fatigued most of the time. If you keep hitting the snoozing button rather than waking up energized each day, mold may be the culprit.

• Smell

When things in your house smell a bit more musty than they did, even if you have done an extreme general cleaning, your problem may be mold. One clue that mold is the reason for a musty odor in the home and not a lack of cleaning is if there is a stronger smell in one part of the home or a room corner. If you have taken out the trash, steamed the curtains, and washed the carpet and the musty odor remains, this could very well be mold.

Mold can infest clothing as well as grow in basements. This is particularly true in damp clothes. If you tend to dry your laundry on an outdoor rack or leave your wet towel on the floor, mold can grow on the clothing and irritate your skin. Keep your wet clothing dry as soon as you can to prevent this. Avoid letting wet towels accumulate in your shower room.
