How Common Is Mold In Homes

Hazard Classes Of Mold Types In Homes

Common Types Of Mold Found In Homes | Real Estate

Some countries have adapted a hazard class system to place molds in different categories based on their health risks. They are broken into Hazard classes A, B and C:

  • Hazard Class A:The mold types in this group are either directly hazardous to health due to risk of infection or creation of toxins. They should not be in homes or workplaces and should be removed right away if found.
  • Hazard Class B:The mold types in this group can cause allergic reactions, especially over longer periods of time.
  • Hazard Class C:The mold types in this group arent known to cause any health risks or reactions in humans. Note, however, that even molds in this category can potentially cause structural damage to things that they are growing on, and should still be gotten rid of.

Where To Check For Mold In Your Bathroom

You may love a long, hot shower but, unfortunately, so does mold. The warm, wet environment of a bathroom is practically an invitation for mold growth. Bathrooms that lack proper ventilation are especially prone to attracting mold. While it may be clear to check for mold on shower tiles, there are plenty of less obvious places for mold to grow in the bathroom.

The Biggest Threats To A Healthy Home

The most common types of mold include aspergillus, cladosporium and stachybotrys atra .

Aspergillus is a fairly allergenic mold that is commonly found on foods and in home air conditioning systems. Cladosporium is typically a black or green “pepper like” substance that grows on the back of toilets, painted surfaces and fiberglass air ducts. While this mold is nontoxic to humans, it can trigger common allergy symptoms, such as red and watery eyes, rashes and a sore throat.

Mold that appears to be orange or red in color is typically found outdoors, given its nature to thrive on decaying plants or moist wood. This type of mold, which can appear slimy, is harmless and should only be removed for aesthetic purposes.

White mold is not technically a type of mold, but the good news is that this typically indicates the mold is only in the early stages of growth and can easily be treated.

Mold Reactions: Who’s At Risk

For people sensitive to mold, inhaling or touching mold spores can cause allergic reactions, including sneezing, runny nose, red eyes, and skin rash.

Treating Mold Can Be Expensive

Pin on Removing Home Mold

Once a mold infestation affects a home, it can take a great deal of money, time, energy, and resources to eliminate the problem.

First, youll have to hire a specialized mold inspector. Youll need a trained specialist to be able to identify the type of mold in your home and their potential health risks.

Once the mold inspectors determine the state of your mold problem, youll need to remove it completely. If the mold infestation is fairly advanced, you may need some major structural work to eliminate the issue. For instance, it might require cutting into drywall or even complete demolition to some parts of the home.

Serious mold problems need to be treated using special mold-resistant solutions. This can be something like anti-fungal paint, as mentioned earlier. It may also involve using special seals and curing the trouble area. These solutions can get very expensive and rather inconvenient as it restricts you from using your house to its fullest capacity.

In worst-case scenarios, your home may be condemned, especially if it is infested with toxic mold. This is an extreme scenario and often preventable if you catch the mold issue early enough.

Mold Can Spread To The Hvac System

Mold infestations get exponentially worse if they spread into heating and air conditioning systems.

Mold feeds on dust and moisture, which is plentiful inside of an HVAC system. This increases the likelihood of mold spores circulating in a home. Spores can spread through the air, entering into your familys lungs and causing potential health issues. Having mold around is never healthy and it gets exponentially worse when that mold is breathed in. This is one of the major causes of the health risks associated with having mold inside of a home.

Poor Ventilation In Your Home

As we mentioned before, a poorly ventilated home is a magnet for the growth of mold and the spreading of mold spores.

The stagnant air throughout your home is one of the best environments for the growth of mold. So make sure to rid your home of it on a daily basis!

Steam created by appliances, cooking, and bathing creates humidity in your home, leaving surfaces damp and sticky.

Remove the moisture from your home and youll remove the likelihood of mold growth.

    Exposure Sources And Prevention

    7 Most Common Types of Mold Found In Homes l Remedics

    The primary sources of mold exposure are from the indoor air in buildings with substantial mold growth and the ingestion of food with mold growths.

    While mold and related microbial agents can be found both inside and outside, specific factors can lead to significantly higher levels of these microbes, creating a potential health hazard. Several notable factors are water damage in buildings, the use of building materials which provide a suitable substrate and source of food to amplify mold growth, relative humidity, and energy-efficient building designs, which can prevent proper circulation of outside air and create a unique ecology in the built environment. A common issue with mold hazards in the household can be the placement of furniture, resulting in a lack of ventilation of the nearby wall. The simplest method of avoiding mold in a home so affected is to move the furniture in question.

    Prevention of mold exposure and its ensuing health issues begins with the prevention of mold growth in the first place by avoiding a mold-supporting environment. Extensive flooding and water damage can support extensive mold growth. Following hurricanes, homes with greater flood damage, especially those with more than 3 feet of indoor flooding, demonstrated far higher levels of mold growth compared with homes with little or no flooding.

They should tell you in advance what they will do or what recommendations they will make based on the sampling results. The results of samples taken in your unique situation cannot be interpreted without physical inspection of the contaminated area or without considering the buildings characteristics and the factors that led to the present condition.

    Do I Need Professional Testing

    In short, usually not! Because, remember the saying: no mold, no matter what color, belongs in a healthy home. And that is good news because a professional mold inspection with testing can run anywhere from $300-$750. In most cases where mold is clearly visible, knowing exactly what type of mold you have is unnecessary. We advise most of our clients to forgo the inspection process and just apply that money saved to the cost of fixing the problem. The EPA agrees that mold testing isnt necessary in most cases.

    There are exceptions, however, such as when a mold inspection with testing is required as part of a real estate sale or if you require proof that a mold problem is present, such as for a legal dispute. If you think you may have a mold problem, but arent sure, then we recommend formal testing from a professional. And if you require clearance testing to verify an all clear after a mold problem is fixed, then professional mold testing is necessary.
