What determines a home’s value? It is a simple question that has a somewhat complex answer. Factors such as location, property size, age, and condition of the home are all considered. The last aspect holds tremendous weight, including structural integrity, potential damage issues, and an unlikely culprit: mold. 

Mold is a serious issue that can have dire consequences if left untreated. How does mold affect a property’s overall value? How does a property with a history of mold lose its value? How much does mold devalue a home? In the blog, we’ll examine these questions in depth.

What is Mold?

Mold is a type of fungus that can grow both indoors and outdoors. It is a common problem in many homes and buildings, particularly in high-humidity or moisture areas. Water damage is the leading cause of mold infestations. Mold can appear as black, green, or white fuzzy patches on walls, ceilings, and floors and have a musty or earthy odor.

It spreads by releasing spores into the air, which can then settle on surfaces and grow. Mold thrives in warm, damp, and humid environments and can appear on wood, paper, carpeting, and fabrics. Food is also susceptible to mold growth if it’s improperly stored. 

Mold exposure can have various health hazards, particularly for people with allergies or respiratory problems, immunocompromised individuals, those under a physician’s care, patients undergoing chemotherapy, elderly persons, and infants. It can even affect those that consider themselves healthy. Long-term exposure and degree of contamination can be factors that affect everyone. Mold spores can cause allergic reactions such as skin irritations, sneezing, runny nose, and itchy eyes and trigger asthma attacks. Long-term mold exposure can cause more severe health problems, such as respiratory infections or chronic lung disease.

The Impact of Mold on Your Home’s Value

Mold is a concern for homeowners and home buyers alike. When it comes to the latter, it’s not something those looking to purchase a property are willing to overlook; in fact, mold growth is considered a red flag. The presence of mold can lower the price of a house by up to 10-30%, depending on the extent of the infestation. 

According to researchers in a 2001 study, one particularly serious mold infestation decreased the overall value of a luxury home by more than half. The loss amounted to hundreds of thousands of dollars. While this was a rare case, the researchers found that reductions up to 25% were expected due to large-scale mold infestations.

So, how does mold devalue your home? 

Physical Appearance

A factor that can impact a home’s property value is its physical appearance. Visible mold contamination, such as black or green patches on walls and ceilings, can make a property look less visually appealing to potential buyers. The mold may also emit an unpleasant odor, which could further deter interested buyers from making an offer.

The presence of mold in a home can also give the impression that it is not well-maintained. In addition to its unsightly appearance, visible mold growth on walls and ceilings may suggest to buyers that the property has not been cleaned thoroughly. Such an undesirable look could make them think twice about investing in the property.

Structural Integrity

While mold can seem like a mere annoyance, it can have severe consequences for the structural integrity of a home. When left unchecked, it can destroy the integrity of a building’s structure, making it unsafe to live in.

One of the most significant ways mold can damage a home’s structural integrity is by weakening the building’s support beams and framing. Mold spores can latch onto wooden beams and consume the wood, gradually weakening the structure. Over time, this can cause the property to become unstable, putting the home’s inhabitants at risk.

Furthermore, mold can cause damage to drywall, insulation, and other building materials. As mold grows, it releases enzymes that break down the cellulose in these materials, causing them to weaken and deteriorate. This decline can lead to sagging walls, crumbling drywall, and other signs of structural damage.

Another way in which a mold infestation can impact a home’s structural integrity is through the production of mycotoxins. Mycotoxins are toxic compounds that some types of mold produce as a defense mechanism. These toxins can harm humans and animals and cause various health problems. In addition to their health effects, mycotoxins can also cause damage to building materials. Over time, the toxins can weaken and degrade the materials, leading to further structural damage.

Health Risks

Mold growth can also pose serious health risks. Mold spores can cause respiratory problems, such as asthma and allergies, skin irritations, headaches, and other symptoms. Long-term mold exposure can increase the risk of more severe illnesses or infections. For those with weakened immune systems, the chances are even more significant. 

People with asthma and respiratory ailments are in jeopardy of enduring serious consequences of mold exposure. However, even healthy people can fall ill. Seniors and infants are considered the most vulnerable age groups.

How to Resolve Mold Damage in Your Home

Though mold is a common problem homeowners face, it is possible to remediate the damage. When confronted with mold damage in your home, swift and effective action can prevent further spread and mitigate potential health risks. Resolving mold issues requires a comprehensive approach that involves identifying the moisture source, removing mold growth, and implementing measures to prevent future outbreaks. 

Hire a Professional to Perform Mold Removal 

Mold remediation is a complex task that requires extensive knowledge and experience. Hiring certified mold removal professionals is best to ensure the job is done correctly. A professional team will assess the extent of the damage, use specialized techniques and equipment to remove visible signs of mold growth, and suggest preventive measures for avoiding future outbreaks. 

Assess the Damage

The next step is to assess the extent of the damage. Depending on the severity of the mold damage, a professional mold remediation company will perform a mold inspection before starting their work. All affected areas will be checked for mold. In some cases, the mold may have caused structural damage requiring repairs.

Identify the Source of Moisture 

The first step in resolving mold problems is identifying the moisture source. Mold requires moisture to grow, so backtracking to discover its starting point is important. Familiar water sources include leaks in the roof or plumbing, poor ventilation, and high humidity levels. Once experts have identified the source of moisture, they can take steps to fix it and prevent mold growth in the future.

Contain the Mold

Once the technicians have assessed the damage and identified the moisture source, they will contain the mold to prevent it from spreading to other areas of your home. They will do this by closing doors and windows and sealing the affected area with plastic sheeting. They’ll wear safety gear, known as personal protective equipment (PPE), such as gloves, goggles, and a mask, to avoid exposure to mold spores.

Clean and Dry the Area

After thoroughly removing the excess moisture from the affected areas, the space is thoroughly sanitized using disinfectants and dried. Mold thrives in moist environments, so removing all water from the area is crucial to prevent mold growth. Fans and dehumidifiers ensure the drying process goes according to plan. 

Repair Any Necessary Damage

If the mold has caused structural damage to your home, you may need to hire a professional to help with repairs and reconstruction. Mold can weaken the structure of your home, and it is essential to address any damage as soon as possible to prevent further problems.

Prevent Future Mold Growth

To prevent mold growth, keeping your home dry and well-ventilated is essential. Fix any leaks or moisture problems as soon as they arise, and use exhaust fans in bathrooms and kitchens to lower humidity levels. Regularly inspecting your home for signs of mold growth, such as musty odors or discoloration on walls or ceilings, is also a good idea.

If plans to put your home on the market are in your future, remember to address any mold issues prior. After all, you’ll want potential buyers to see your home at its best and mold-free!
