What Causes Black Mold In A Basement?

For mold spores to pop up in your basement, the breeding conditions have to be just right.

Before we discuss getting rid of wet basement mold, let’s take a quick look at what leads to its formation in the first place.

Too much moisture: When there’s too much moisture coming into your basement, then there’s a great chance you’re going to develop some mold on your walls and ceilings.

Moisture comes as a result of condensation or leaks, and this blends with oxygen to create a perfect mold-growing environment.

Another cause of condensation is the storage of electrical appliances in the space accompanied by poor ventilation. As the condensation builds up, the environment becomes very humid, and that can lead to growth.

Leakages: There are several causes of leakages, some of which are faulty foundations and damaged pipes. Aging and poor infrastructural maintenance can cause leakages.

Hydrostatic pressure, which is caused by a rise in soil water can also cause a leak in your basement’s foundation. If there’s a water heater in your basement, then it could also be the source of moisture.

Adding to that, if the water heater fails, it could lead to flooding.

Flooding: Mold growth is certain in a flooded basement. This is when large volumes of water are lodged in the spaces below, leading to hydrostatic pressure.

Sump Pump Failure: The sump pump is built to pump water away from your basement, but if it fails to function, then water will remain lodged.

What Does Mold Look Like On Basement Walls?

Aspergillus is one of the most common species of mold you can find in your home. It is dark green in color and also lodges on damp walls, furniture, and ceilings.

Fusarium is another species of mold but is more yellowish in color. Stachybotrys (which is also known as black mold), is blackish in color and has a unique musty smell.

If you have no idea the kind of mold species you have growing in your basement, then it would be wise to consult a professional to help you identify them.

Popular Products For Killing Basement Mold

We have to point out that getting rid of mold today doesn’t mean it won’t reappear later on. This means you have to deal with the real problem to ensure they don’t return, and that’s keeping your basement dry and free of moisture.

Fixing the leaks and improving ventilation are among the things you can do to keep your basement dry.

Follow these basement mold removal DIY techniques below.

  1. Use Vinegar

This is one of the best basement mold removal products you can use. It is also a common item and you probably have a bottle lying around on your kitchen shelf.

Specifically, white vinegar is highly recommended. All you have to do is pour some of the vinegar over the mold then leave it to work for about 5 minutes.

After the time has elapsed, you can then wipe the mold off with a sponge or cloth. This approach is ideal for surfaces that are porous or solid.

  1. Use Tea Tree Oil

Tea tree oil is another great product you can use to get rid of mold on your walls. It’s a tested and trusted fungicide that works well on various surfaces.

To use, first, mix it with water in a spray bottle then shake thoroughly so it all blends in well. You can then spray the mixture around the affected areas then keep scrubbing the wall with a brush until the mold is gone.

  1. Use Grapefruit Seed Extract

One of the reasons grapefruit seed extract is ideal for mold removal is that it also prevents it from reappearing afterward. This simultaneously makes it a mold treatment and mold prevention product.

To use, mix the extract with an equal part of the water in a spray bottle, shake well to blend, then spray the mixture across the walls, ceilings, and any other affected areas.

Leave the spray to work for about 5 minutes, then wipe the mold off with a piece of cloth.

  1. Use Hydrogen Peroxide

Hydrogen peroxide is a handy and non-toxic solution that can be used to get rid of black and white mold in the basement.

All you have to do is mix with water and apply it to the areas where the mold is present. 10 minutes should be enough for the solution to break down the mold, after which you can get a brush and scrub the mold off your surfaces.

  1. Use Borax

Borax is a great product to use, but you have to take caution when doing so. This is because a poor mixture may b harmful if accidentally ingested.

To prepare the solution, mix a cup of borax with a gallon of water. The next step is to apply the solution to the mold and use a sponge to scrub the surface clean.

Besides its cleaning abilities, borax can also get rid of foul mold odors.

With a proper mix, you wouldn’t need to worry about washing the borax solution off the walls.

  1. Bleach

Here is how to get rid of mold in the basement with bleach.

Bleach is a common solution that can be used to fight mold infestation. It kills the mold and all its spores and leaves your surfaces looking fresh again.

Although we have to mention that bleach cannot kill the mold roots, this means they can pop up again if the surfaces remain moist.

This is why basement mold removal with bleach isn’t the most effective approach. Although it can be used if you’re short on immediate options.

Another downside of using bleach is that it cannot be applied on carpets or fabrics since it damages them. They are ideal only on hard surfaces like bathtubs and tiles. It is also toxic, so you should be careful not to ingest it.

  1. Concrobium

This is an EPA-approved chemical that can be used to remove mold, and it is not as toxic as bleach. Another advantage of using this product is that it is cheap.

Besides removal, it can also prevent mold from reoccurring if well applied. Surfaces like plastic, wood, tiles, and stones can all be treated with concrobium.

  1. High-Efficiency Particle Absolute (HEPA) Vacuum Machines

HEPA vacuums are a great remedy against mold, and they can also kill the spores in the process.

If your basement is high in humidity, doing regular vacuums with a HEPA machine can also prevent mold from growing in the first place.

What Can You Do To Prevent This Problem?

Treating mold is one thing, stopping it from growing again is another.

You can use the tips below to keep mold away from your basement.

Use a negative air pressure machine:  This can be used to filter the air in your basement via a process known as ducting (this is when mold spores are filtered away).

Keep your basement moisture-free: When there is excess moisture in your basement, there is a great chance of mold growth. You can remedy any moisture problems by fixing all the cracks and leaks in the basement.

This condition is important in the fight against mold on a basement ceiling.

If your sump pump is damaged, be sure to repair it or get a new one. The pump takes the water away from your basement and keeps it dry. You can also use a dehumidifier to keep moisture levels below 60%.

Use sealants: This material can be applied to the interior of your basement walls to keep moisture from penetrating. You can also buy a mold inhibitor, which can be mixed with paint.

Unclog your gutters: If your gutters are clogged, then there won’t be a proper flow of water away from your foundation. Make sure that your drainage system is free of debris for better flow.
