How to Remove Mold in the Basement

Once you have noticed mold formation on your basement walls or anywhere else, it is best to take care of it. Molds can spread like wildfire, so you should remove them ASAP! 

There are many ways to remove molds. You can use either the natural way or the synthetic way. It is best if you use proper mold removers since they give the best results. You can use any of the mold removers above since they are some of the best in the market.

Basement wall mold

There are other options available too. You can also use a steamer, bleach, borax or hydrogen peroxide. However, mold removers are recommended as you don’t need special equipment and don’t bleach fabrics or carpets.  

The process is pretty simple, and you can do it yourself without calling a professional.  

Study the area

Before you decide to take on the task, make sure that it is doable. Mold growth that is less than 10 sq. ft can be removed at home; otherwise, you may need to call a professional. You must also check if the mold spores have reached great depths.  

Depending on how severe the growth is, you can choose any of the mold removers mentioned above.  

Ventilate the basement

The removal process will require you to use harsh chemicals or agents that may be harmful if you inhale. Therefore, open even the tiniest of windows or doors in the basement and let air circulate.  

Clear the surroundings

You may need to spray solutions that can harm other items in the basement. Make sure that the surrounding area around the mold growth is clear.  

Spray the mold remover

  • Apply: Spray the mold cleaner evenly on the surface and wait for a few seconds or minutes. If you are using any of the removers above, then you have to wait for a few seconds for the spores to die.  

The stains will disappear, and if they are stubborn, then you may need to do some light scrubbing.  

  • Wipe: After waiting for some time, grab a few paper towels or a cloth and wipe the area.  
  • Repeat: Repeat the process if you can still see stains or mold growth. In the case of molds that have penetrated deeper, you will need to repeat the steps many times.  

After you have removed all molds from the basement, it is best if you could find the underlying cause of mold and fix it.  

Common Causes of Basement Mold

The ideal condition required for mold thriving in the basement is moisture. Some of the common causes that cause this issue are: 

Water leaks

Water drops dripping down the wall

Water leakage from pipes contribute to raising the moisture levels in the air and providing the necessary moisture for mold to survive.  

Excessive moisture

Excessive moisture in the basement due to condensation leads to the formation of mold. Appliances stored in the basement often cause excess moisture buildup in the area.  

Lack of Ventilation

Lack of ventilation means air circulation is poor. When air circulation is poor, condensation is more likely to occur. Any form of condensation in a room will give more time for molds to form. 

Previous flood

Floods that have occurred before causes high levels of water to build up in the soil underneath in the basement foundation. A porous basement surface can hold moisture and be another source of  molds. 

A leak from water heater

Water leakage from water heaters causes a pool of water to form and gives additional moisture for molds to form in the area. 

Types of Basement Mold

There are many types of fungi that can grow in basements. Here are the most likely ones to form in your basement.  


Aspergillus is a big fungi family that grows rapidly. It has a powdery look and can be black, white, green, or yellow in color.  These fungi can cause Aspergillosis, which is an infection that affects your respiratory system. It is best to call for professional help if you notice this fungus in your basement.  


Acremonium is commonly found in concrete walls, drain pans, or window sills. It has a velvety appearance, and its color can range from whitish-grey to pink. Acremonium can cause infections in both humans and animals.  


This fungus commonly grows in places that have suffered water damage. The appearance and color change from whitish to brown or black later. It is a cottony mold that can cause eye, skin or even nail infections in humans.  


You will find this fungus mostly on damp or wet wood, on damp carpets, walls, cushions or window frames. It has a smooth texture and changes color from cream or pink to dark brown or black. 


Ulocladium grows very well on wet walls and indoors. So, you will most likely see this in your basement. These dark-colored fungi pose a risk for allergic reactions in some individuals.  


Mucor likes to grow in cold places and is most seen in buildings with water damage or leaks. The mold can be white, yellow or greyish-brown in color.  Some strains can cause skin infections in humans.  

How to Prevent Mold From Forming in the Basement

Preventing mold from forming is relatively straightforward, and the key is controlling the humidity and moisture levels.  

Use a Dehumidifier

A dehumidifier is a device that uses air conditioning to maintain a level of humidity in the air. Molds need moisture in the air to grow. Controlling the level of humidity ensures that molds have a harder time taking root in the basement. A right dehumidifier can suck the moisture out from the air, create the right climate to retard mold growth.

Dehumidifiers do not actually kill the mold spores. They will still remain dormant, waiting for an ideal condition to sprout. But it does help in denying the conditions for them to thrive. Ideally, a humidity level of below 60% is enough to prevent molds from forming in the basement. 

Identify and fix leaks

A dehumidifier will be ineffective if there is a leak. You can identify leaks by a close inspection of the basement. Look for stains on floors, ceilings and walls. Wet spots or wet walls can be an indication of a leaky pipe. Cracks in the foundations could lead to stress in the water pipes, which could mean they are leaking.   

A dead giveaway sign would be visible mold or mildew in such places. Some subtle signs are musty odors, a sudden increase in water usage or slight sounds of water running when it isn’t being used.  

Clear Clutter

Clutter lying around your basement can trap moisture and cause molds to form. Clutter prevents air circulation. It can also collect moisture depending on where its located. Clutter on a cement floor can sap up the moisture. Clutter can also contain food sources such as crumbs leftover on a plate, and mold can form there.

Molds thrive in anything that collects dust and holds moisture—items such as fabric, paper or wood. Refrain from hoarding such items in the basement. 

Ventilate area well

Good Ventilation will ensure that air is always in circulation and minimize mold growth by wicking away moisture for molds to form. It also helps in keeping the basement dry by allowing moisture to escape. Improper Ventilation may cause mold to grow.

Install an exhaust fan or open windows, if any, to let fresh air circulate.  If there is any furniture, make sure they are placed 4-6 inches away from the walls so that air flows between them. 

Insulate pipes

Insulated pipes

Insulate as many pipes and hoses as you can to prevent them from leaking. Exposed pipes, if not insulated, can freeze, burst and flood the area. Pipes carrying cold water can have condensation develop on the outside, also known as sweating, and this can increase humidity levels.  

Clean frequently

Cleaning frequently will remove mold spores that enter your basement. When cleaning, look for nooks and crannies and areas that are exposed to moisture. Wipe spills or leaks immediately. In case flooding has occurred, ensure the affected area has been dried for 2 days before using it again. 

Considerations When Looking For Basement Mold Removers

According to the products mentioned above, there are different types of mold removal best suited for the surface and the kind of mold. There are certain factors that you must consider when choosing a mold remover for your basement.  

For starters, is it a wall or floor mold? In the case of wall molds, you need to go for products that can deeply penetrate through the porous concrete and attack the mold roots. If it is on the floor, then you can use a remover that works well on hard surfaces.  

Another factor is to consider the extent of the mold. If the mold growth is heavy, then you will need super strong mold removers. Go for removers that have a powerful formula that directly attacks the mold roots. Also, you may need to repeat the process a number of times if there’s too much mold.  

Lastly, study the type of mold. As seen earlier, some types of molds are dangerous to humans. If you notice such mold, then contact the professionals directly.  


How to test for mold?

Testing for mold basically means-testing for fungal spores. Some fungal spores may be harmful and toxic; hence it is better than it is tested in a lab so that professionals can study and understand its potency. There are two methods of testing molds.  

Air Test

In the air test, you install a device that allows you to measure the number of mold spores floating in the air. It is better if the device is the same as the ones used by professionals since they are more accurate. You can even use an indoor air quality monitoring device. There is no specific number of mold spores that are considered a threat to human health.  

Surface Test

In the surface test, you scrape off a small sample of the mold, pack it correctly and send it to a laboratory for testing. If you want to do it yourself, then you can buy a surface test kit online. In cases when you are not sure how to do it, always call for professional help.

As mentioned earlier, some fungal spores may be toxic, so you have to be very careful. Always choose laboratories that are approved by reputed organizations such as the American Industrial Hygiene Association (AIHA).  

How much does it cost to hire a professional to remove basement mold?

Hiring a professional will cost between $600 to $3000. It largely depends on how severe the mold growth is and the size of the basement.  

Can you remove mold without chemicals?

Yes, there are many natural ways to kill molds. For example, steam is a popular method used for killing mold spores. Even heat-resistant fungi will die out with well-applied steam. Just adjust the heat to maximum heat setting on the steamer, and spray on the molds.  

Is there a quick DIY chemical mix to remove mold?

No, this is not recommended as some mixes can create very toxic fumes. 

Conclusion & Recommendation

Molds are a pain if not taken care of in time. They can spread and cause permanent structural damages to your basement. When buying mold removers for the basement, it is imperative that you choose the right one to get rid of them for good.
