To test your house for mold, hire a certified Indoor Environmental Professional (IEP) or licensed mold inspector to conduct air quality and surface testing. Alternatively, you can use a DIY test kit for surface or air sampling.
AFS offers free mold testing, including crawl space mold inspections, to help homeowners uncover potential problems and address them before they worsen. Our team will evaluate your property, identify the causes of mold growth, and recommend the best solutions for moisture control and long-term prevention.
10 Warning Signs of Mold Toxicity
Sometimes, mold can be visible on the surface of walls, ceilings, or floors. Smell Test: Mold often produces a musty, damp smell. If you notice any unusual odors in the basement, it might be a sign of hidden mold. Moisture Meters: You can use a moisture meter to check for moisture in the walls.
Exposure to indoor mold is associated with elevated CRP and C3a concentrations in serum, while the effect on C5a concentrations is ambiguous.
Most IMIs are caused by breathing in (inhaling) mold spores in the air. IMIs can also be caused by mold getting into the body through cuts or wounds or from contaminated medical equipment. The two most common types of IMIs are mucormycosis and aspergillosis. IMIs are rare but cause severe, life-threatening illness.
How can I address mold exposure?
You can usually see or smell a mold problem. Mold can appear as slightly fuzzy, discolored, or slimy patches that increase in size as they grow. Most molds produce musty odors that are the first indication of a problem. Mold can grow anywhere there is adequate moisture or a water problem.
Baking Soda. Used with vinegar and water or alone with water, baking soda is effective at removing mold naturally. Dissolve baking soda into water or a water-and-vinegar solution, and spray onto the moldy surface. Let it sit, then scrub and wipe with a damp cloth.
While air filtration can help reduce airborne mold spores, an air purifier alone will not eliminate indoor mold growing on or beneath surfaces, such as walls and floors. Dr. Fineman emphasizes that effective indoor mold control requires managing moisture and humidity to prevent conditions that promote mold growth.
Neurological abnormalities may present as dizziness, balance issues, coordination difficulties, or movement disorders. In severe cases, mold toxins can cause seizures, confusion, and delirium. These symptoms are primarily due to immune responses and inflammation triggered by mold spores and mycotoxins.
A blood test, sometimes called the radioallergosorbent test, can measure your immune system's response to mold by measuring the amount of antibodies in your bloodstream known as immunoglobulin E antibodies.
This explains why mold toxicity is often misdiagnosed as fibromyalgia, chronic fatigue syndrome, or anxiety. The symptoms overlap with those of many other conditions, making it “the great imitator” in modern medicine.
Most mold-infested homes can be saved: Even houses with extensive mold contamination can typically be restored to safe, habitable conditions through professional remediation, though the process may be complex and costly depending on the severity of the infestation.
Symptoms caused by a mold allergy can include:
The cost varies based on the size of the affected area, the severity of the infestation, and the extent of any structural damage. In the UK, small area treatments might range from £200-£500, medium-sized properties £500-£2,000, and severe infestations requiring extensive work could exceed £2,000 to £10,000+.
Specifically, air purifiers with HEPA (high-efficiency particulate air) filters work great at removing mold spores. HEPA filters are considered to be rated MERV 17 or above, which means that the filters can trap more than 99.7% of air particles as small as 0.3-1.0 microns in size.
Mold releases microscopic spores into the air, and those particles circulate throughout the home, especially at night when rooms are closed and ventilation is limited. Even people who feel fine can experience irritation, disrupted sleep, or longer-term respiratory effects over time.
If you want to stop mold from growing, a dehumidifier is essential. By keeping humidity levels below 50%, it eliminates the conditions mold needs to thrive. If you want to reduce airborne mold spores, an air purifier is beneficial. It helps maintain cleaner indoor air and prevents the spread of spores.
The acidity of vinegar isn't enough to destroy the mold root system or deactivate airborne spores. Pro tip: Even if the surface looks cleaner, mold can still grow underneath, and come back fast without proper remediation.
Research has shown that English Ivy can eliminate up to 78% of airborne mold within 12 hours. This makes it particularly useful in humid areas like bathrooms and basements where mold growth is more common.
Using Hydrogen Peroxide to Kill Mold
Pour 3% concentration hydrogen peroxide into a spray bottle. Spray the moldy surface completely to saturate the area with hydrogen peroxide. Leave the surface to sit for 10 minutes. Scrub the area to make sure to remove all the mold and mold stains.
Additionally, spraying a solution of equal parts vinegar and water or a diluted hydrogen peroxide solution into the air can help to kill airborne mold spores.
Visually, it may be greenish-black, grayish-black, slimy, or more furry than other forms of mold or mildew. If you try to clean it with a heavy-duty cleaner, you might find that it remains on the surface and doesn't completely wipe away.
