Let’s get into each of the mold dangers in turn. 

How Can Mold in a House Affect You?

Your health can be directly influenced by mold exposure. Contacting with mold for a prolonged time can cause several diseases, including allergic reactions, respiratory issues, asthma attacks, nasal congestion, and more. Let’s indulge in each one

Respiratory Issues 

Mold can be an obvious reason for your respiratory issues. If you’ve been facing heavy breathing or shortage of breathing, wheezing, or coughing – mold is to look for. As per WHO report, 30-50% of increases have been noticed in respiratory diseases caused by mold. 

Allergic Reactions

Mold and its spores are tiny and can be inhaled through air. They grow in vents, ducts, HVAC, and other components through which they easily travel and breathe into your lungs. This triggers allergic reactions such as runny nose, itchy eyes, skin irritation, sneezing, and more. 

Asthma Attack

If you’re already suffering from asthma, mold can be a triggering element to breathe. It may cause coughing, wheezing, irritated or inflamed airways, shortness of breath, chest tightness, and even worse. Extended mold exposure may lead to you needing emergency medical help. As per EPA, about 4.6 million asthma cases are caused due to mold. 

Fungal Infections

People with weakened immune systems can fall prey to fungal infections. Maybe your home is under mold attack, and you didn’t notice. This leads to poor indoor air quality, causing fungal infection in your lungs. 

Hypersensitivity Pneumonitis

Living in molded indoors can cause hypersensitivity pneumonitis. It is a lung inflammation that gets triggered by inhaling dust or mold, leading to an allergic reaction. This condition also causes fever, cough, and breathing problems. 

Mold Problems in Homes

Mold can reside in the kitchen, bathroom, basement, ceilings, floors, behind the walls, and any other corner of your home. It doesn’t even spare your home components and can make their colonies into vents, ducts, HVACs, air conditioners, and others. 

Mold can damage your home structures, such as wooden furniture, and cause warping, rotting, and decay. And what’s more interesting is that it can feed on anything your home has. Mold will not only weaken your home’s structures but also affect your home’s curb appeal and marketability. 

Weak Structures

Your home components can decay over time due to mold growth. For instance, wooden furniture, shingles, and more. The home’s structures can also drop their strength and shine due to mold proliferation. 

Insulation Problem

When the HVAC, air conditioning, ducts, and vents are subject to mold attack, you may notice insulation problems. The mold travels through the air into the HVAC system, polluting indoor air quality. It will not only decay the insulation but also clog the air ducts or coils. 

Drywall Damage

Mold could be hidden behind your drywall. It can cause water leaks and moisture damage to your drywalls. Ultimately, the drywall structure will get stained, crumbled, or softened. The damage could spread to the extent that you’ll have to replace your drywall.

Property Curb Appeal

When mold patches are present on the walls, ceilings, and floors, it will damage your home’s curb appeal. Besides damaging your home’s theme, it will influence the existing home’s aesthetics. And negatively impact your home’s outlook for the future as well. 

Property Value

As per the Appraisal Journal research, a home’s market value can be reduced from 20% to 37% due to its mold issues. It’s commonly understood that no one would want to buy a home under a mold attack. Whether you’re buying a home with mold or selling your own – the home value would be significantly compromised. 

However, if you choose a mold inspection timely, you can save your property from depreciation. Getting a professional mold inspector on your service will identify existing and potential problems. He will also give you suggestions to avoid mold problems in homes.
