Whether your concern is aesthetic or medical, you don’t want mold in your basement. It’s gross, it smells, and it can cause cold-like symptoms (if not worse). There’s a lot of conflicting information on mold removal on the internet; but that’s typical, right? Sometimes I think the internet specializes in conflicting information.
Acculevel, however, specializes in something a lot more useful: foundation repair and basement waterproofing. Since our start in 1996, we’ve helped more than 35,000 homeowners restore their homes to optimal health and stability. Our coverage area includes our home state of Indiana, and portions of the surrounding states.
Some articles will use fear tactics to get you to read them. Most of these reference the dangers of “toxic black mold.” This is not our plan. Yes, mold can have a strong negative effect on people’s well-being; but it is rarely the boogeyman it’s portrayed to be.
We are going to cover factual information about mold, how to get rid of it, when you need a professional’s help, and how to prevent mold from growing in your home.
What is Black Mold?
All molds are types of fungus, and they come in a wide range of colors including black. When people talk about “toxic mold” or “toxic black mold,” they’re probably referring to the mold strain called stachybotrys chartarum. It is definitely not good for people, but most of the stories about it causing hemorrhages or similarly catastrophic health problems are urban myths. As of the time this article was written, we still have no proof that a mold can cause such major health problems in the average person.

Who is Vulnerable to Mold-Related Health Problems?
Some people are at greater risk of respiratory problems (lung-related illnesses). This includes the following groups:
- Infants and very young children, whose immune systems are still developing.
- People of any age that have mold-specific allergies. This includes anyone who is allergic to mushrooms, penicillin, or other types of fungus.
- Anyone who has a compromised immune system, including the elderly, diabetics, those with lupus, etc.
- People with asthma, COPD, or other respiratory ailments.
What Are the Most Common Signs You Are Allergic to Mold?
Generally speaking, mold allergies closely resemble the symptoms you have with hay fever, other seasonal allergies, or a cold. They range from the mild to the more severe, depending on how much exposure you have to the mold:
- Itchy, watery eyes or blurring vision
- Sore throat
If you have these symptoms and they will not go away, or they worsen when you are in the basement? It’s probably an allergy. If you don’t take any action, this can eventually lead to more substantial illnesses like bronchitis or pneumonia.
How Do You Remove Black Mold?
If the mold only covers a small area, and you’re not allergic to it, cleaning it off your basement wall or floor is possible. You will need to use warm soapy water and a rag or sponge that you are comfortable discarding after use. You don’t want to wash and re-use that cleaning material on other surfaces.
Make sure you are using a cleaning solution that is designed for cleaning mold/mildew off of porous surfaces. (Concrete, brick, and the mortar used with brick or stone are all porous.) Be a smart consumer: read the instructions carefully and take the recommended precautions. These are usually simple things like wearing rubber gloves, and opening windows for ventilation.

If the mold is covering a larger area (the EPA specifies 10 square feet or more), or it needs to be scraped off the surface, you need to hire a professional. The photo above is a great example of mold that has to be scraped before it can be cleaned or sealed. This type of mold removal requires more industry-grade PPE (that’s personal protective equipment). You also need to be trained and equipped to remove the mold and all the debris. If this is not done properly, the mold can release spores and actually spread to other areas.
How Do You Prevent Black Mold?
Preventing black mold, or any color mold, means you have to address the cause of the mold. Mold is a symptom, an indication that you have a bigger problem in your basement. You don’t get mold in your basement without a source of moisture.
Start by finding out how water/moisture is getting into your basement. Check all of your plumbing and pipes for possible leaks. If you find any, hire a local plumber to remedy the situation immediately. Not only is a leaky pipe feeding mold in your basement, but it’s wasting water that you have to pay for!
If all of the plumbing is solid, move on to the windows and doors in the basement. Water may be seeping in around the edges of the frames. A good general contractor can replace the flashings, repair the frames, or even replace them if necessary.

The water may be coming through a crack in the foundation; if this is the case, you’ll need a foundation repair company like Acculevel. Please do not hire a general contractor to work on your home’s foundation. This is an area where you need an expert; your entire home relies on the foundation to remain stable and secure.
But it is always possible the water source is none of these things. Remember: your foundation is built out of a porous material. Water may be coming directly through the wall or floor. This would mean your home needs a waterproofing system installed. If there’s no actual water in the basement, but it’s damp and humid? A high quality dehumidifier may be what you need.
