How to Detect Mold Inside Your Walls
Detecting mold inside walls can be challenging because it often grows out of sight.
However, there are several signs and methods you can use to identify potential mold issues. Recognizing these early warning signs can help you take action before the problem becomes severe.
Musty Odor
A persistent musty smell is often a strong indicator of mold growth inside walls. If you notice an unusual odor that doesn’t go away with regular cleaning, it’s time to investigate further. This smell is caused by mold releasing microbial volatile organic compounds (MVOCs) as it grows.
Discoloration and Stains
Look for discoloration or stains on your walls, which can appear as black, green, or brown spots. These spots may indicate mold growth behind the wall surface. Discoloration is a visual clue that mold might be spreading within the walls, even if it’s not yet visible on the outside.
Peeling or Bubbling Paint
Mold can cause paint to peel or bubble as it grows and releases moisture. If you see any changes in your wall’s paint, it’s a sign that mold could be present. Moisture trapped behind the paint weakens its adhesion, causing these visual defects.
Health Symptoms
Increased allergy or respiratory symptoms, such as coughing, sneezing, or itchy eyes, when spending time in a particular room may indicate mold growth in the walls. These symptoms occur because mold spores and mycotoxins can irritate the respiratory system and trigger allergic reactions.

Safety Precautions: What Not To Do When Checking for Mold Inside Walls
When checking for mold inside walls, it’s essential to take safety precautions to avoid spreading mold spores or exposing yourself to harmful substances.
Here are some key things to avoid to ensure your safety and the safety of others in your home.
Do Not Disturb Mold
Avoid cutting or drilling into walls unless absolutely necessary, as this can release mold spores into the air. This increases the risk of inhalation and can spread mold to other areas of your home. If you must access the inside of a wall, take precautions to contain any disturbed mold spores.
Avoid Using Harsh Chemicals
Do not use harsh chemicals to clean suspected mold areas without proper protective gear. Harsh chemicals can cause harmful reactions and exacerbate health issues, especially when used in enclosed spaces. Always research appropriate cleaning solutions and ensure you are adequately protected when handling them.
Do Not Ignore Protective Gear
Always wear protective gear, including gloves, an N95 mask, and safety goggles, when inspecting for mold. Protective gear minimizes your exposure to mold spores and helps prevent respiratory problems and skin irritation. Ignoring these precautions can lead to serious health risks, especially if you have existing respiratory conditions or allergies.
Tests to Confirm Mold Inside Walls
Once you suspect mold inside your walls, performing specific tests can help confirm its presence. These tests can identify the extent of the problem and guide you in deciding the best course of action for removal and remediation.
Take Moisture Meter Readings
A moisture meter can detect high moisture levels within your walls, which often indicates mold growth. Moisture is a key factor in mold development, so identifying areas with elevated moisture can help locate hidden mold.
To use a moisture meter:
- Turn On the Meter: Follow the manufacturer’s instructions to calibrate and prepare the moisture meter for use.
- Press the Probes Against the Wall: Place the meter’s probes or pins against the wall in various locations, especially near suspected mold areas, leaks, or water damage.
- Check for Elevated Readings: High moisture readings suggest the presence of moisture within the walls, which can support mold growth. If you find areas with consistently high moisture levels, it’s a strong indicator that mold may be present behind the walls.
Take a Surface Swab Test
A surface swab test can confirm mold presence on the wall’s surface. This test involves collecting samples from the suspected mold areas and sending them to a lab for analysis.
Here’s how to perform a surface swab test:
- Obtain a Mold Testing Kit: Purchase a mold testing kit from a hardware store or online. These kits typically include swabs, sample containers, and instructions.
- Swab the Wall: Use the provided swab to collect samples by gently rubbing it over the suspected mold areas on the wall. Make sure to follow the instructions carefully to avoid contamination.
- Place the Swab in the Sample Container: After collecting the sample, place the swab in the provided container and seal it securely.
- Send the Samples to a Lab: Mail the samples to the specified lab for analysis. The lab will identify the types and concentrations of mold present, providing detailed results.
Additional Testing Methods
In addition to moisture meter readings and surface swab tests, there are other methods you can use to detect mold inside walls:
- Infrared Camera: An infrared camera can detect temperature differences in your walls, identifying areas with hidden moisture and potential mold growth. This non-invasive method helps visualize moisture patterns that aren’t visible to the naked eye.
- Air Sampling: Air sampling involves collecting air samples from within the suspected area and analyzing them for mold spores. This test can detect airborne mold spores that may indicate hidden mold growth inside walls.
Professional Mold Inspection Services
When dealing with potential mold inside your walls, sometimes it’s best to call in the experts. Professional mold inspection services offer comprehensive evaluations using advanced tools and techniques to accurately detect mold growth.
These experts can perform thorough inspections, including thermal imaging, moisture mapping, and air quality testing, to identify hidden mold that might not be visible to the naked eye.
By using these specialized methods, professionals can locate the source of moisture causing the mold and provide detailed reports on the extent of the infestation.
Hiring a professional service ensures that mold is detected accurately and efficiently, minimizing health risks and potential damage to your property.
They can also offer recommendations for effective mold remediation strategies and preventative measures to avoid future mold problems. Investing in professional mold inspection services provides peace of mind, knowing that your home is thoroughly checked and safe from mold-related issues.
FAQs
How do I know if I have mold inside my walls?
To determine if you have mold inside your walls, look for several key signs. Musty odors are a strong indicator of hidden mold. Additionally, discoloration, peeling, or bubbling paint on your walls can signal moisture and mold issues. Health symptoms like increased allergies, respiratory issues, coughing, sneezing, or itchy eyes when spending time in a particular room can also suggest mold growth. Pay close attention to these symptoms, especially if they improve when you leave the affected area.
Is it safe to remove mold myself?
Removing mold yourself is generally safe for small areas if you use proper protective gear, such as gloves, an N95 mask, and safety goggles. Utilize appropriate cleaning solutions like a mixture of bleach and water or commercial mold removers. However, for extensive mold growth, it is best to hire a professional to ensure thorough and safe removal. Professionals have the experience and equipment to handle large infestations, preventing further spread and ensuring complete eradication.
What should I do if I find mold inside my walls?
If you find mold inside your walls, the first step is to address any moisture issues immediately. Fix any leaks or sources of water infiltration to prevent further mold growth. Once the moisture problem is resolved, remove the mold using appropriate cleaning methods, such as scrubbing with a bleach solution or mold remover. For extensive mold problems, consider consulting a professional to ensure safe and thorough removal, as they can provide a more comprehensive approach to remediation.
Can mold inside walls make you sick?
Yes, mold inside walls can release spores into the air, which can cause a range of health problems. These include respiratory issues like coughing, wheezing, and shortness of breath, as well as allergic reactions such as sneezing, runny nose, and itchy eyes. Individuals with pre-existing conditions like asthma or weakened immune systems are particularly vulnerable to mold-related health issues. Long-term mold exposure can lead to more serious health complications, so it’s crucial to address mold problems promptly.
How can I prevent mold from growing inside my walls?
Preventing mold growth inside your walls involves several proactive measures. Control indoor humidity levels by using dehumidifiers and ensuring proper ventilation, especially in high-moisture areas like bathrooms and kitchens.
