WHAT IS MOLD? WHERE DID IT COME FROM?
Before we talk about the symptoms of mold, let’s think about what mold is and how it ends up in your home.
From the arctic to equator and all the places in between, mold lives literally everywhere. Molds are fungi, and grow from microscopic spores that are everywhere in the air. Molds are important for recycling organic matter (such as leaves). The recycling process they perform returns nutrients to the soil, and is important for plants to grow.
In order to grow, molds need four things to grow: oxygen, moisture, a food source, and the right temperature range (ideal is between 77F – 86F). It is difficult to impossible to control the temperature and amount of oxygen in the unconditioned spaces in your home (attic, crawlspace, behind cabinets, etc). So, let’s think about the things you can control when it comes to mold.
Molds grow inside of their food sources. They penetrate deeply into drywall, carpets, floors, cabinets, underneath kitchen and bathroom sinks, etc. Anything with carbohydrates in it could be considered a food source for molds.
Moisture is the one thing you can reasonably control when it comes to mold. A dry home equals a home with much less mold growth. Keeping areas dry, especially areas that use water frequently (like bathrooms), is important to prevent mold growth.
How Fast Do Molds Grow?
Moisture behind baseboards and cabinets, wet carpet tack strips, in crawl spaces, basements, and other hard to reach areas are a ticking mold time bomb. Once enough moisture is present, molds can begin to grow in less than 48 hours! Even with fans going and mopping up the water, it may not be enough to prevent mold growth.
Symptoms of Mold in Your House
Sometimes you can visibly see or smell mold growing, but other times it is more difficult to detect. Tight spaces such as in attics, behind cabinets, and in crawl spaces are not places people are likely to venture. There are 3 ways to tell if you have mold: 1 you might see it, 2 you will probably smell it, but 3 a comprehensive mold inspection by Branch Environmental will definitely find it! The best way to know if you have mold is to get a comprehensive mold inspection performed. Keep reading to learn more about how you can identify the symptoms of mold in your home.
Symptoms of Mold in your House – What Does Mold Look Like?
Mold is usually a black, white, brown, green, gray, or yellow, fuzzy growth. Sometimes you can see it. Sometimes you can’t because it is hidden in the dark recesses of your home. Places like attics, crawlspaces, basements, behind cabinets, inside floors, etc. are great places for mold to grow.
It’s not easy to see mold, but if you have any water leaks in your home, you are much more likely to find it! Flooding is of course a major problem, but usually people notice when pipes have burst or flood waters have invaded their homes. These are dramatic events!
However, tiny cracks in pipes and hoses, and clogs in drains can become a nightmare if forgotten long enough. Tiny leaks over a long period of time can cause as much or more damage than flooding water type events. Because they go unnoticed, tiny leaks can cause more damage than most people realize. Remember we talked about how mold has plenty of food sources in your home? All it takes is that tiny bit of extra moisture and mold starts growing. In most cases it starts within 48 hours!
The main sources for mold growth in homes are water leaks from faucets, roofs, hot water heaters, ground water damage and even sewer backup. Find the water leaks and find the source of the problem.
Is Mold Dangerous?
In one word… Yes.
All molds have the potential to cause irritation and allergy symptoms. It is important to note that the longer you are exposed to the mold, the more pronounced your symptoms become. At first, it might just be allergy symptoms, but over time (weeks, months, years) mycotoxins build up in your system, and can make you sicker and sicker.
Not all molds are toxic, but many are. Mycotoxins can cause health problems ranging from poisoning to cancer. You can be affected by mycotoxins even if you are not allergic to mold.
Before we go any further, let’s clear up the confusion about ‘toxic black mold.’ When you read about ‘toxic black mold’ it is kind of misleading. The thing is… dangerous and toxic mold is not just black, it can be many different colors. Toxic molds can appear to be green, yellow, brown, and black. Any of the colors you see could be producing mycotoxins. You can’t tell if mycotoxins are present just by looking or smelling. You have to perform a laboratory test.
So, What is a Mycotoxin?
Mycotoxins, literally ‘fungus poison’ in Latin, are secondary metabolites that can be produced by molds, and are not living organisms. Mycotoxins are a byproduct of mold. Not all mold spores produce mycotoxins, but some do. So the molds that produce mycotoxins are the ones that could be categorized as toxic or poisonous.
So, where is the line between an allergic mold and a toxic mold? That line is defined by the presence of mycotoxins, and is NOT defined by color. Mycotoxins are invisible and cannot be detected just by looking at the mold growth.
What Do Mycotoxins Do?
These chemical substances can cause many health problems ranging from mild to severe. Even if you are not allergic to mold, you can be affected by mycotoxins.
Mycotoxins can be absorbed by the body in a number of ways including: through the skin, the airways (inhalation), and through the intestinal lining (ingestion). Detrimental health effects caused by mycotoxins can range from “acute poisoning to long-term effects such as immune deficiency and cancer.”2 Chronic disease sufferers, such as people with immunosuppressive disorders or underlying lung disease may be more sensitive to molds and mycotoxins in their environment.4
The main ways people and pets become poisoned by mycotoxins include breathing contaminated air or eating contaminated foods. Simply breathing contaminated air can introduce the mycotoxins into your lungs! Foods such as apples, cereal grains, coffee beans, nuts, spices, dog and cat food, and more can become contaminated with fungi that produce mycotoxins. Mycotoxins are NOT something you want in your home! Keep reading to learn how you can remove them.

Symptoms of Mold in your House – What does mold smell like?
Do you smell that? Did you forget to wash your gym clothes? Does the dog need a bath? I cleaned everything, and I can’t find the stench! It’s so musty! What could it be?! If this sounds like your home or office, you might have a problem with mold and MVOC’s.
MVOC’s or Microbial Volatile Organic Compounds are compounds created by fungi and bacteria during their metabolic processes. MVOC’s can be detected by simply smelling the air. The smell of MVOC’s has been compared to stinky socks, locker room odor, wet dog, or old cheese. They give off a distinctly musty, moldy smell. There are over 200 compounds that have been identified as MVOC’s. MVOC’s can be dangerous and even toxic to humans. MVOC’s can be mycotoxins or can cause allergy symptoms. It depends on which ones are present. If you smell odors like this, you may have a mold problem in your building.
There are also compounds called VOC’s or volatile organic compounds that can be produced by household cleaners, paints, aerosols, disinfectants, air fresheners, glues, and even furniture. VOC’s are not caused by mold or other microbes, and give off a distinctly chemical scent. VOC’s can cause health problems as well.
What Kinds Of Damage Can MVOC’s Cause?
There have been over 200 different chemical compounds identified as MVOC’s that are produced by fungi and bacteria. The chemicals produced include alcohols, arsenics, benzenes, toluenes, acids, sulfur compounds, and many more. Many but not all of these chemicals are mycotoxins and are harmful to people and pets simply by breathing them in.

Our answer depends several factors including:
- how extensive the mold problem is
