What Does Mold Smell Like In A House

What does mold smell like in a house? No one likes to think about mold but its something that you need to be aware of, especially if you own a home. The thing about mold is that it can go undetected for months at a time. This is because it can start out very small so there are virtually no visual signs of a mold infestation. Once you notice mold on your walls or in your vents, the problem is already widespread. Therefore, you need to rely on your other senses and some additional clues to figure out if mold is making its way into your living space.

Musty Smells Understanding Why

Does a musty smell under my floors mean there’s mold or mildew?

The first step to solving any problem is understanding it, and this is especially true with musty carpet syndrome. This trouble sometimes happens in above-ground rooms, but its most common in basements. Thats because concrete floors covered directly in carpet are so common down there.

Imagine for a moment that youve got carpet on a cool concrete floor somewhere, and the outdoor air outside your home is 30ºC with a 90% relative humidity. Thats your typical hot, humid day. The thing to understand about relative humidity is that its relative to temperature. The cooler the air is, the less moisture air can hold. So as this warm air makes its way into your house through open windows and natural air infiltration, some air will eventually enter the pile of the carpet, sneaking down towards that concrete floor. As the temperature of this humid air declines in contact with the cool concrete, relative humidity skyrockets because the air right there within the carpet is less able to hold moisture. If this cooling continues far enough , relative humidity of the air at the interface between your carpet and the concrete will rise to 100%, triggering something unfortunate. In fact, that 86ºF air at 90% relative humidity only needs to cool down to 83ºF to hit 100% relative humidity. They call this the dew point, and they do so for a reason.

Your air conditioning system.

If you have cental HVAC, an air conditioning system involves three separate components:

Difference Between Mold And Mildew

Perhaps one of the easiest ways to understand the difference between mold and mildew is their visual appearance and growth profile.

Mildew has a flat growth profile, meaning that it does not grow with a fluffy or cottony texture that can sometimes be seen on other types of mold. Where other molds may resemble mini mushrooms, mildew will grow flat and can often go undetected unless growing in large quantities.

That being said, mildew is just another type of mold , and shares many of the same characteristics and qualities.

Both mold and mildew are spread through tiny, microscopic spores, and both thrive in damp, moist environments. And, of course, both come with that musty smell from the MVOCs that they give off as they grow and spread!

The dank musty odor signifies the presence of microbial volatile organic compounds . Traditional volatile organic compounds are mainly industrial made chemicals with low molecular weights, high vapor pressure and low water solubility. MVOCs are released from metabolic processes of decay agents like fungi, bacteria and biofilm. The off gassing of MVOCs include a wide range of alcohols, ketones, aldehyde, esters, carboxylic acids, lactones, terpenes, aromatic hydrocarbons, sulfur and nitrogen compounds.

You don’t need to know scientifically how MVOC’s are formed, however, you must know it is caused in most causes by water damaged porous materials. This could mean drywall, clothes, flooring, etc.
