What makes a musty smell in homes?
There are several reasons you may notice a musty smell in your house, but the most common cause is the presence of mold and moisture accumulation. When mold forms in your home, it releases something called Microbial Volatile Organic Compounds, or MVOCs. These MVOCs have a very pungent odor that will instantly draw attention. A moldy or wet smell in the house is likely because you have too much moisture somewhere in the home caused by a leak or standing water. This excess moisture can be found underneath your floorboards, HVAC ductwork, or even behind walls and under wallpaper. Mold thrives in damp, dark environments and can live anywhere in temperatures between 40 and 120 degrees. As the mold spores release into the air, they can cause areas of your home to have a wet, musty smell.
If you notice a wet smell in your house, it’s most likely due to mold growth. In many cases, this mold isn’t clearly visible, so you’ll need to do some closer inspection. Start by looking in areas like the basement or rooms with higher moisture levels, such as the bathroom, kitchen, or laundry room. You may need to remove a section of floor molding or look underneath your floors to determine whether or not mold is actually present. So, where does mold come from? You can track mold spores inside from your shoes, or your pets may bring them inside once they attach to their fur. Mold spores also float in the air and can get inside when you leave a door or window open. It’s also found on old bread and rotting food, but most mold in homes thrives on wood and paper materials, such as wallpaper.
What does mold smell like?
So, what does mold smell like in a house, and how can you tell if it’s in your home? Many people describe mold’s smell as stale, musty, or earthy.

Pungent is another good word to describe the smell of mold, unlike other common household smells that you may notice, such as cooking food or dusty areas that smell more stale than pungent.

Mold exposure can also cause severe headaches for many people. However, these headaches could be due to the sniffling and congestion associated with the mold and mildew exposure. Many people feel something similar to a sinus headache since the irritation can create pressure in the sinus cavities. Black mold, also known as toxic mold, can cause a condition called mycotoxicosis, also known as mold poisoning. Mold can release a toxic substance called mycotoxins, leading to many serious health problems. The symptoms of mold and mildew positioning include body aches and pains, mood swings, and severe headaches, and may also cause nosebleeds or memory loss. If you’re concerned about mold exposure or want to know whether you have a mold allergy, talk to your doctor.
