Hidden mold in your home can be dangerous and go unnoticed for months. Mold often grows in concealed areas like walls, under flooring, or in attics, creating potential health risks and structural damage. This blog will help you identify the signs of hidden mold, understand its risks, and learn how to detect it. Additionally, we’ll answer common questions about hidden mold and its effects.
What Is Hidden Mold and Why Is It a Problem?
What Causes Hidden Mold to Grow?
Mold thrives in damp, poorly ventilated areas. Hidden mold develops in concealed spaces such as behind walls, under flooring, and in crawl spaces. These areas often retain moisture for long periods, creating the perfect conditions for mold growth.
Common causes of hidden mold growth include water leaks, condensation, and high humidity levels. All of these main causes involve moisture – the key to mold growth. By understanding these main causes, homeowners can take proactive steps to reduce moisture buildup and prevent mold from becoming a problem.
Why Is Hidden Mold Dangerous?
Unlike visible mold, which can be spotted on walls and other surfaces, hidden mold grows out of sight, such as behind drywall, under flooring, or inside ventilation systems. This type of mold often goes undetected, allowing it to spread unchecked for long periods.
Hidden mold can negatively impact air quality, as the mold releases spores and mycotoxins that can cause various health issues. For instance, mold can cause health problems such as respiratory issues, worsening allergies, skin and eye irritation, and weakened immune system. Mold can cause dangerous health issues for anyone, but it can be particularly dangerous for those with mold sensitivity.
Beyond health concerns, hidden mold can be dangerous for your home or building, causing severe structural damage.
How to Find Hidden Mold in Your House
Common Places Where Hidden Mold Grows
Since mold thrives in dark, damp spaces, certain areas of a home or building are more susceptible to hidden mold growth. Basements are one of the most common places for hidden mold due to naturally high humidity levels, potential water damage, and lack of light. Similarly, attics provide the perfect environment for mold as poor insulation, roof leaks, and poor ventilation can lead to moisture buildup. Hidden leaks and water damage often make the inside of walls and ceilings, as well as under carpet and flooring, common places for hidden mold growth. Heating, ventilation, and air conditioning (HVAC) systems circulate air throughout buildings, but they can also spread mold spores in moisture builds up inside or around vents.
Hidden mold isn’t always visible, which is why it is important to conduct regular inspections to detect early warning signs. When inspecting, use a flashlight to check for discoloration or stains on surfaces, as well as peeling or bubbling paint.
Using Your Senses to Detect Mold
In addition to visible signs, your senses can often detect mold growth too. Musty odors, unexplained allergies, or warped surfaces can all point to hidden mold. Bubbling or cracking noises can indicate water damage behind walls or under flooring. When inspecting for mold growth, listen for bubbling, cracking, or dripping sounds that may indicate water damage behind walls. Additionally, creaking or soft spots when stepping on floors can be another indicator of mold growth, as prolonged mold exposure causes wood rot.
Tools and Tests to Detect Hidden Mold
Detecting mold can be challenging, but there are various tools and tests that can help uncover mold growth behind walls, under floors, and in other spaces.
A moisture meter is an effective tool for detecting areas with excessive moisture. As previously mentioned, excessive moisture provides the perfect breeding ground for mold growth. An infrared camera can also be used to locate moisture behind walls or under flooring. In addition to measuring the moisture levels of an area, air quality tests and surface samples from at-home mold testing kits can detect mold spores. However, it’s important to note that results can come back inconclusive from these DIY mold detection procedures
While DIY methods may suggest a mold problem, it’s crucial to invest in a professional mold inspection. Professionals can confirm mold presence and provide expert solutions to a potential mold problem.
Signs of Hidden Mold in Your House
Physical Signs of Hidden Mold
Hidden mold tends to lurk behind surfaces, but it can leave behind noticeable clues. Changes in appearance and texture of surfaces can indicate moisture buildup and mold growth. Knowing what to look for can help you detect mold before it spreads further.
Physical signs of mold growth include peeling wallpaper, discolored patches on walls or ceilings, and warped wood. If parts of your walls or ceiling feel soft or slightly bulged, trapped moisture and possible mold growth may be underneath. Also, frequent condensation on windows, pipes, or walls can signal high humidity levels, which encourage mold growth.
Health Symptoms Caused by Hidden Mold
Hidden mold doesn’t just affect your home – it can have a significant impact on your health. If you’re experiencing unexplained health issues, hidden mold could be the culprit.
Common symptoms of mold exposure include sneezing, headaches, fatigue, or irritated eyes. Prolonged exposure to hidden mold can worsen these symptoms, including asthma, or lead to serious respiratory issues.
Can Hidden Mold Make You Sick?
Short-Term Effects of Mold Exposure
Exposure to mold, even for a short period, can cause noticeable health symptoms. Mold spores in the air can trigger a range of health issues that develop quickly after exposure. Immediate symptoms can include coughing, sneezing, and skin irritation. However, people with allergies or asthma may experience more severe reactions.
Long-Term Health Risks of Hidden Mold
Prolonged exposure to hidden mold can lead to more serious and severe health issues. Over time, chronic exposure to mold can lead to respiratory illnesses, neurological symptoms, and immune system issues. The risks are particularly high for individuals with asthma, allergies, or weakened immune systems.
Health risks also depend on the type of mold. For instance, certain mold species, like black mold, produce mycotoxins that can cause serious harm.
Addressing mold problems early can prevent long-term damage to both your home and your health.
How to Prevent Hidden Mold in Your Home
Tips for Maintaining a Mold-Free Home
Preventing mold growth starts by managing moisture and keeping your home well-ventilated.
A dehumidifier can help control indoor humidity levels. To ensure proper ventilation, use exhaust fans in bathrooms, kitchens, and laundry rooms to prevent moisture buildup. Opening windows, when possible, will promote fresh airflow while reducing condensation. Additionally, it is crucial to fix leaks immediately and seal areas prone to water intrusion. Keeping moisture under control will help ensure a cleaner, healthier living environment free of mold growth.
Regular Home Maintenance Practices
In addition to keeping moisture levels under control, it’s important to routinely inspect your home and keep essential systems in good condition.
When performing home maintenance, inspect high-risk areas for signs of water damage at least twice a year. This includes checking basements, attics, bathrooms, pipes, faucets, water heaters, and behind appliances. To prevent mold spores from circulating in the air, replace HVAC filters every 1 to 3 months. It’s also important to clean ventilation ducts and air conditioning units to prevent moisture buildup.
By incorporating these habits into your maintenance routine, you can significantly lower the risk of mold growth in your home or building.
What to Do If You Discover Hidden Mold
DIY Mold Removal vs. Professional Remediation
When dealing with mold, it’s important to understand when a DIY approach is sufficient and when professional remediation is necessary.
Small patches of mold can be cleaned with proper safety equipment and cleaning agents. However, extensive mold growth or mold in accessible areas should be handled by professionals.
Professionals use industrial-grade equipment that will eliminate mold at its source. Tackling mold by yourself might only temporarily solve the issue. If you suspect a serious mold issue, seeking expert mold remediation services is the safest option.
Steps to Take Before Mold Remediation
Before mold remediation, taking the right steps can minimize risks and ensure a smooth process.
First, you’ll want to document the mold damage by taking clear photos and videos for insurance purposes. Next, it is best to consult a mold remediation expert for advice. If the mold covers more than 10 square feet, is inside walls, or has caused structural damage, it’s best to invest in professional mold remediation services. Before remediation, you will need to seal off affected areas to prevent spore spread. If the mold contamination is extensive, you might need to temporarily relocate to avoid exposure and prevent health concerns.
