Mold is an unfortunate, yet common problem that grows in homes. It can affect the health of your family, in particular, if someone in your home has a mold allergy or has a compromised immune system.

Unfortunately, because of how dangerous mold potentially is, it can make selling a home extremely difficult, and the cleanup process isn’t as simple as just spraying bleach like you may have heard.

What Is Mold and How Does It Affect Your Family?


Mold, sometimes spelled “mould,” describes fungi that grows in threadlike structures. Although mold treats some bacterial infections and is part of the creation of some foods, not all of it is safe. Some of it grows from moisture and can even lead to respiratory infections. It grows in different colors and sizes and has numerous species.

Mold harms the quality of the air in homes. While those who are allergic to the fungi experience itchy eyes, a runny nose, and sneezing, the toxic forms of mold can cause hair loss and even cancer. Some molds stain clothing and fabrics. It’s also possible for them to destroy the actual structure of a building.

Identifying Different Types of Mold in Your Home

All the species of mold that exist classify in one of three different categories – allergenic, pathogenic, or toxigenic.

Allergenic molds trigger an allergic reaction in people who have full-blown allergies or sensitivities to mold. For those who have asthma, this classification of mold causes asthma attacks.

Pathogenic molds cause health issues for people who suffer from illnesses that reduce the body’s defenses.

Molds that categorize as toxigenic molds produce toxic substances that lead to serious consequences and even potentially death. In cases of toxigenic mold exposure, occupants in a residence must vacate until a professional treats the problem.

Some examples of varieties of mold include acremonium, alternarnia, aspergillus, aureobasidium, cladosporium, fusarium, and mucor.



Acremonium mold classifies as a toxigenic mold that changes its appearance over the course of time. Generally, it begins as a small, moist mold that converts into a fine powdery substance. Generally, acremonium mold appears gray, orange, pink, or white. Typically, you find this mold in drain pans, window sealants, or cooling coils.


As the most common form of allergic mold throughout the world, alternaria has a velvet-like texture and looks like brown or dark green hairs. It thrives best where it’s moist, which is why you can commonly find it in bathtubs, showers, or below leaking sinks.


Aspergillus is one of the more common forms of mold found in homes throughout America. This type of mold has long, flask-shaped spores and tends to grow in layers, sometimes forming long chains of mold. Aspergillus mold forms in various colors based on the species, including yellow, green, or black.


Aureobasidium is an allergenic mold that usually grows behind wallpaper or on wood or paint. Usually, it begins as a pink, brown, or black mold but turns to a darker brown color as it ages.


As a mold found in both warm and cold places, cladosporium thrives in upholstery, carpets, and fabrics. The mold feels like suede and appears olive green or brown. It categorizes as an allergic mold.


Similar to cladosporium, fusarium is able to grow and reproduce even in colder temperatures. It’s both allergenic and toxigenic and tends to grow where there’s water damage. It appears reddish, white, or pink. If you have fusarium in one room, it’ll spread to other rooms in your home rather quickly.


Mucor is a form of allergenic mold that typically grows in thick, white or grayish patches. This form of mold grows fast and usually develops around HVAC systems, ductwork, or air conditioning units.

Can You Sell a House With Mold?

Determining the answer to “can you sell a house with mold,” depends on the level of mold damage in your home. If you have a water leak and significant mold growth, it can impact how quickly your home sells as well as for how much.

Selling a house with mold is possible, but it depends on the type and extent of the mold in your home as to whether it affects the sell. Some forms of mold are more common and aren’t really a problem for people who have an average immune system and who aren’t sensitive to it.

People who are looking for a home decide if a home is worth the value by estimating the price of the home along with the cost of any necessary. Depending on the type and size of the mold problem, it’s possible for the issue to get costly to repair.

What Can You Do About Mold When You’re Selling Your Home?

Start treating a mold problem as soon as possible. It’s best to start even before you put your home on the market because it can take time to remove mold. If possible, you don’t want the listing of your home to mention anything about model remediation.

First Steps for Treating Mold

Face the mold problem head on and act immediately. You don’t want to pass the problem of mold onto the future buyer because more than likely, your real estate agent is going to disclose information regarding the mold to prospective buyers.

If you see or smell mold in your home, start by determining where areas prone to moisture are. Make the necessary repairs to reduce the amount of moisture in your home.

If you have a serious mold problem, you should have an inspector evaluate the issue. If you would have to reveal you had a mold problem, having proof of an inspection shows you’ve taken all the necessary steps to correct the problem.

Treating a Mold Problem Yourself

If you have a small patch of mold, you can treat it yourself. Begin by sealing any doorways or other openings using duct tape and plastic. Position an exhaust fan near any outdoor openings in the room.

Wearing a respirator or face mask designed for mold spore protection is necessary if you have a weakened immune system, a mold allergy, or toxic mold.

Remove visible mold using soap and a sponge. Spray dry, moldy areas with water to reduce the prevalence of airborne mold spores. Use a mold removal product in the area to disinfect it. Place all of your cleaning materials in a heavy duty garbage bag and remove it from your home immediately to avoid re-contaminating your home with spores.

Hiring a Professional for Mold Remediation

Some mold problems require a professional company to completely remove all of the fungi. For instance, toxic mold and mold in large quantities aren’t typically manageable using household products sold in stores.

Preventing Mold Growth in Your Home

You can purchase paint that’s resistant to mold to prevent mold. You want to fix leaky pipes immediately and remove as many sources of moisture as possible. A dehumidifier can help with minimizing moisture as well. Make sure your yard drains away from the house.

Who Can Buy a House With Mold


You know the answer to “can you sell a house with mold,” which means you know people will buy a home with mold.

Everyone responds differently to it, so you could live with mold and never even notice it’s there. Keep in mind, if you have a strong immune system, minimal health problems, and no allergy to mold, the fungus won’t harm you.

Buying a home from SoCal with mold can actually save you money, especially if you’re not going to move in right away and have time to have the problem treated.

Although mold is not always causing problems, it’s best to have it removed before you move in, which is part of the benefit of purchasing from SoCal. Prices for a home with mold from SoCal are very fair, and it allows you the opportunity to spend a minimal amount on mold cleanup rather than paying the price a real estate agency charges for a home without mold.

What to Do When Buying a Home With Mold


It’s possible to purchase a home with mold in it and not spend a fortune. When you buy with SoCal, the company assumes responsibility for repairs on the home before you receive it, so much of the expenses associated with mold removal are taken care of before you buy the house.

When you buy with Socal, you eliminate the stress.

Typically, you’d have to hire someone to inspect the home, then they’d notify you of a mold issue and how significant it is. Then, you’d choose to take the necessary steps to correct the problem.

You might be able to treat the problem on your own using a cleaner you purchase in the store, but you’d want to start drying out the house, even if it requires commercial-grade equipment. You also would need to repair any leaks or sources of moisture.

It’s possible to use specialized spray on the areas with mold in order to cleanse them. If the problem is severe enough, you’d need to contact a professional. You’d need to get several quotes before selecting a company, though.
