Black mold can cause severe health issues, including allergic reactions.
Black mold grows easily and spontaneously if moisture is present, and it typically finds a home in drywall where it feeds on the paper facing once that facing becomes damp. A general rule of thumb is that black mold can take hold within 24 hours.
Once drywall is exposed to water — whether from a leaky pipe, flooding, or high humidity — mold growth starts immediately. That’s because the paper backing on drywall provides a food source, and the material itself traps moisture, making it the perfect breeding ground for mold to reproduce.
Black mold is an especially toxic type whose mold spores float into the air, causing health issues from mild symptoms such as a runny nose to more serious issues such as a weakened immune system, asthma symptoms, sinus infections, and other serious health issues.
In this guide, we’ll examine the causes of black mold, the dangers of exposure to it, and how to prevent it.
What Is Black Mold?
Black mold, scientifically known as Stachybotrys chartarum, is one of the most dangerous types of mold commonly found in homes with consistent moisture. It thrives in damp, poorly ventilated areas — especially where water leaks or humidity levels are high.
Black mold is common in hot and humid areas, but it can also appear where temperatures are only temporarily high, for example, in the summer. This often happens in Colorado, where temperatures and humidity can temporarily rise, causing a spike in mold growth that would otherwise be uncommon in a colder climate.
Why Does Black Mold Grow So Fast?
Mold grows quickly because it doesn’t need much to get started — just moisture, a food source (like wood, paper, or dust), warmth, and poor airflow. Once mold spores land on a damp surface, they can start growing almost immediately.
Mold spreads by releasing millions of microscopic spores into the air. These spores float around until they find another damp spot to land on — and the cycle starts again. The more moisture and humidity in the air, the faster it happens. That’s why leaks, flooding, or high humidity can lead to a full-blown mold problem almost overnight.
The Health Issues Related to Black Mold
Breathing in black mold, especially over a long period, can cause various health problems. Black mold can be life-threatening if you deal with allergies, asthma, or have a weaker immune system. It often starts with stuff like a runny nose, sore throat, or nagging cough, and some people notice skin irritation or sinus pressure that just doesn’t go away.
In more serious cases, mold exposure can lead to fatigue, trouble breathing, or worsened asthma. For those with compromised immune systems, it can even raise the risk of infections. If your home smells musty or you’ve been feeling off for no apparent reason, it might be time to take a closer look and deal with it before it worsens.
How and Where Does Black Mold Grow In My Home?
Mold can appear anywhere in your home where it’s warm and damp, including basements, cupboards, or attics. Mold grows anywhere wet and warm and reproduces by sending spores into the air.
If not addressed quickly, black mold can infest insulation, carpets, and even structural beams, resulting in costly damage and increasing the risk of exposure. The longer the mold is allowed to grow, the more difficult it becomes to remove. That’s why fast action is key when dealing with any water intrusion or musty smell in your home.
Why and How Does Black Mold Form in Drywall
Drywall is a Petrii dish for mold, especially when exposed to high humidity or water from a leak or flooding. Here are a few key reasons why mold spreads so easily in drywall — and how your home’s environment might be helping it grow:
- Moisture levels caused by high humidity create an ideal mold environment. Keeping indoor humidity below 60% can help mitigate the risk.
- Mold thrives in warm, humid temperatures. Keeping your home cool can help slow down mold growth.
- Drywall is made from gypsum and paper backing, a food source for mold. Other organic materials in your home can also contribute to mold growth.
- Poor air circulation can trap moisture in corners and enclosed spaces, enabling mold and its spores to multiply quickly.
If you can smell or see black smudges on your walls, your drywall is likely hosting a black mold infestation.
Black Mold Prevention
Black mold is notoriously difficult to completely get rid of if it’s penetrated deep into your home’s structure. For example, beams and flooring can become infested with mold and must be removed entirely to be safe again, but you can avoid structural damage by taking a few simple steps.
- Use dehumidifiers in damp areas to control humidity
- Open windows and use exhaust fans to get air flowing in moisture-prone areas to improve circulation.
- Insulating pipes can prevent condensation and reduce the risk of water damage.
- Check for signs of leaks in the walls, under sinks, or even in the attic
Follow these few steps to prevent hazardous black mold from entering your home and causing health problems.

Frequently Asked Questions
How quickly can black mold develop after water damage?
Black mold (Stachybotrys chartarum) can begin forming just as fast as other types of mold — within a day or two of water exposure. If the moisture isn’t dealt with immediately, it can spread rapidly and lead to serious health risks and structural damage.
What causes drywall water damage?
Drywall is porous and easily absorbs moisture from leaks or floods. It can even absorb humidity in the air or condensation from AC units. So, keeping the air in your home as dry as possible is critical. Common culprits include burst pipes, roof damage, or overflow from tubs and appliances.
Can I fix water-damaged drywall myself?
You’re taking a risk trying to repair water-damaged drywall. If the damage is minor and there’s no sign of mold growth, you may be able to dry it, sand, and repaint. But if the area stays damp or mold appears, it’s best to bring in a trained professional for safe removal and cleanup.
What’s the best way to dry out wet drywall?
Start by stopping the water source, then use fans, dehumidifiers, and open windows to circulate the air. In many cases, especially with deep saturation, you’ll need to cut out and replace the affected sections to remove trapped moisture entirely.
What health issues can black mold cause?
Black mold can trigger stuffy noses, sore throats, coughing, and skin rashes. People with asthma or a weak immune system are especially at risk for breathing issues or a life-threatening allergic reaction. This can lead to more serious problems like breathing, sinus infections, or chronic fatigue.
What should I clean with after everything’s dry?
Use white vinegar, hydrogen peroxide, or a bleach solution (for non-porous surfaces). Always wear gloves and ventilate the space. It’s smart to call a pro if it’s a big job.
