How To Prevent Mold From Growing On Walls
The most common causes of mold growing on walls include:
Moreover, we can also thank:
We explained humidity above, so it is time to devote a word or two to other two most common mold causes.
Condensation forms when water vapor in the air meets cold surface and cools to become liquid. With enough moisture and an organic food source, you can see mold developing on your walls. The same goes for water leaks leaking pipes near or inside the wall can lead to excess moisture, which in turn will cause mold to grow.

Youll want to focus on two items increasing the temperature and the air flow. Addressing these issues will lower the humidity and the mold growth/musty odor.
Purchase a relative humidity gauge and install it in the basement. Your goal is to keep the RH below 50%. Increase the heat as necessary to lower the RH until youve reached 50%.
The easiest way to increase the ventilation is to run a bathroom exhaust fan. If theres an existing fan in the basement, run it at least 12 hours per day in the winter months.
Its also important to verify whether the basement is suffering from vapor emissions through the concrete slab. This occurs when water vapor moves up through the slab and into the room above. If the basement is carpeted, the moisture can become trapped and lead to mold growth. See our page on basement mold for more info.
What Does Mold Need In Order To Grow
The truth is not much is needed for mold spores to grow out of control. Ideal conditions include lots of moisture and food. Indoor mold growth is fueled by moisture. This explains why mold is such a common problem in highly humid and damp areas like bathrooms and basements.
In addition to moisture, mold also needs nutrients, which it finds in a variety of materials like paper, wood, drywall or any organic material. More information available in our article about causes of mold growth.

Does Mold Die When It Dries Out
It is a common belief that dry mold is safe, but is this true? Yes and no. While mold spores wont multiply without a source of moisture, they will re-activate and start growing once they come into contact with water again.
Not only does mold and mildew damage walls, tiles, carpets and other surfaces around the house, but it is capable of causing a multitude health issues. And although each person responds to mold differently, countless studies show that exposure to mold spores can trigger reactions that range from mildly allergenic to pathogenic and even toxigenic.
So what do you need to know about mold in order to prevent its growth and protect your health? Here is some basic information.
What Humidity Level Does Mold Die
Another way to control mold growth in your home is the maintenance of a proper humidity level. Most houses have HVAC systems that can help balance the moisture and dryness of the air indoors.
Note that warm air absorbs more moisture than cold air, so the ideal humidity inside should range from 30% to 50% to prevent mold buildup. Using exhaust fans in moist areas such as bathrooms, kitchens, and laundry areas will be of big help. They encourage proper ventilation so the steam and vapor in the air do not stay in place.
Investing in dehumidifiers will also help in keeping the humidity low inside your house. You can also open your windows more for a natural exchange of air but be sure to keep them closed when raining to prevent water intrusion.
However, active molds can still prosper despite these conditions, so be sure to end the source so they will not grow again. You can use mold repellent products that you can buy in stores and sanitizers, and active cleaners. You can also use bleach as it is a proven effective product to eliminate mold growths and spores.
Targeting the problem from the roots will end it all. You can assure that they will not reactivate again or harm any of your family members despite being dormant.

What Happens When You Dry Out The Fungi
When mold that was previously wet dries out, does it become neutralized? If only!In fact, dry mold can be an equal if not greater threat than wet mold, despite no longer being able to produce billions of mold spores. Since the mold spores already out in the open have dried out, they become lighter, thus making it easier for them to become airborne and spread throughout your home.
Its for this reason that its not enough to simply dehumidify your houseyou want to get the mold spores themselves out of there! Otherwise, people vulnerable to mold spores may continue to experience uncomfortable symptoms like skin rashes, coughing, itchy eyes, etc.
If the mold contamination is under 10 square feet, its perfectly fine for you to try to fix the issue on your own. But if its more than that, its best to hire a mold removal professional to get the job done safely.
How To Prevent Mold After A Flood

The sooner you dry your home, the less likely mold will grow after a flood.

Can Mold Really Grow In Dry Conditions
Well, the short and confident answer Is NO.
Mold spores need water to survive, and without it, they stop growing and multiplying.
So if you are 100% sure that your walls, floors, wood, and furniture are completely dry and moisture-free, then, normally, you should not have mold problems.
If you do, then there are only 2 possible reasons:
Reason 1
The mold you see is old and inactive. This means that it grew when you still had moisture issues. But now that youve dried out your house, the mold spores have remained on the walls and still need to be removed and cleaned up.
Yes, unless you actively remove mold from the walls, it will stay there and not go away. We will discuss this later..
So its just a cleaning problem here. No need to worry
Reason 2
Now If you have cleaned the mold but you still see it growing and spreading, then there is only one explanation left:
Your walls and surfaces are not as dry as you think they are.
It could be as simple as a small amount of moisture left behind surfaces that still need to be removed, or it could be a leak or a broken hose keeping water flowing behind your walls.
Either way, since you still have water behind your substrates, you still run the risk of mold growth.
As we said, its very important to know that there are some species of mold that can survive with only a very small amount of water and very low humidity levels.
In The Walls And On The Floor
From top to bottom, mold growth is likely in a bathroom. In addition to the places mentioned above, pay attention to any water leaks coming from the walls or floors these leaks can cause mold to grow quickly. Bathroom rugs are also known to harbor mold, and are usually not washed as often as they should be.
Some tips to keep your bathroom free of mold
- Use a ventilation fan during your bath or shower, and keep it on for at least 30 minutes after
- Use a dehumidifier or air conditioner to keep humidity levels down throughout your home
- Keep all surfaces, including counters and floors, clean and dry
- Check for leaky faucets and pipes

Moisture: The Mold Instigator
Mold thrives in moisture. For it to grow, it needs a combination of these conditions:
- First, it needs a warm location.
- Next, there needs to be moisture present .
- Finally, it needs organic materials that provide nutrients.
When all three of these conditions are present, it creates the perfect storm for mold.
This fungus is attracted to organic materials like paper, wood, or drywall. It also loves dark, dank places like basements, bathrooms, and beneath carpets. Some other common locations to spot it include kitchens, laundry rooms, and pool patios.
What do all of these locations have in common? The presence of moisture nearby. Without moisture, mold wont reproduce and spread rapidly. But with it, it can quickly grow into an out-of-control infestation.
So, is mold without moisture under control? Lets take a look.
