When buying or retaining a property, mold is a major risk that impacts health and structural integrity. Mold grows in damp, humid situations and spreads rapidly, almost invisibly to the casual observer. If you are suspicious that mold may be present in your building or workplace, hiring an inspector specializing in mold assessment can provide you with a clear definition of what is happening. But what does a mold inspector look for during an inspection?
A mold inspection is a detailed process that involves identifying the presence of mold, determining its severity, and locating the sources of moisture fueling its growth. Mold inspectors use specialized equipment and techniques to uncover hidden mold, assess potential risks, and recommend appropriate actions to address the problem. In this blog, we will break down the essential things a mold inspector looks into during a mold inspection so you know what to expect if you hire one.
1. Visible Mold Growth
Visible growths of mold are the most noticeable things a mold inspector checks. Usually, mold grows in moist, damp, dark, and badly ventilated areas. It might come in black, green mold, white mold, or even orange. Common places where it grows include:
Bathrooms, especially in areas with poor ventilation like showers and behind toilets. Kitchens, particularly around and under sinks, dishwashers, or refrigerators, where water leaks might occur. Basements and crawl spaces that are exposed to humidity and leaks. Attics, especially near roofs or vents, may have water infiltration. A mold inspector will visually inspect these and other areas of the property where mold may grow. The inspector will also look for water stains, discoloration, or other signs of mold growth that could indicate hidden mold colonies.
2. Signs of Water Damage
Excessive moisture usually means mold. The most active areas where one would search for molds are places with water damage experiences beforehand. General indications that can easily be associated with water damage include the following:
- Water stains on the walls and ceilings
- Painted wall or paper peeled due to bubbling.
- There is water on your carpet, floors, and walls
- Drywall wood has warped and become swollen.
- An odor reminiscent of mold or a musty/earthy smell is produced when moisture tends to be held up.
The mold inspector can begin to look at areas with the potential for water damage, indicating where most molds would likely be found. They may also search for an active source of water leaks feeding the problem.
3. Moisture Levels in the Property
Moisture causes mold to grow. Therefore, a key job for a mold inspector is to check moisture levels in a property. The inspector uses tools like moisture meters and hygrometers to measure humidity in different home areas. These tools can find too much moisture in drywall, wood, and insulation. In places where mold may be present, the inspector uses moisture meters to check the moisture trapped inside surfaces. If there is a high moisture reading, it means the area is prone to growing molds. High humidity is another factor contributing to molds, so areas with poor ventilation will be checked for humidity, such as in basements and attics.
By identifying areas of excessive moisture, the mold inspector can pinpoint the source and suggest solutions to prevent future mold growth problems.
4. Hidden Mold Growth
Mold is also infamous for growing behind walls and beneath floors, in air ducts, and even in insulation. A mold inspector might have specialized tools such as an infrared camera and moisture meters to detect mold growth that’s not easily noticeable.
Infrared cameras assist mold inspectors in identifying areas of temperature differences, which may reflect trapped moisture behind walls or ceilings. If the moisture is there, mold will likely follow. The inspectors can discover those hidden problems before they spread and cause additional damage.
Apart from infrared technology, mold inspectors may take air samples or swab surfaces for mold spore testing. These tests unveil hidden mold colonies that could affect air quality.
5. Air Quality Testing
Airborne mold spores can harm your health, even without visible mold growth. Mold inspectors often perform air quality testing to measure the number of mold spores in the air. This is especially important when mold is suspected but not visible or when the mold growth is hidden in walls, ceilings, or ducts.
The inspector will take air samples using a spore trap device, which specializes in this task. The spore trap captures mold spores from the air and forwards them to the lab for analysis. This might prove helpful in ascertaining the concentration of dangerous spores in the air.
Air quality testing is important because it will identify possible health risks, especially for individuals with respiratory issues or mold allergies. It will also determine whether mold remediation is required to improve indoor air quality.
6. Moisture Source
Mold loves environments with excess moisture. Among the important things to do in a mold inspection is to identify the source of moisture feeding the mold. Mold inspectors will check the property for sources of water infiltration, including:
- Leaky pipes or plumbing fixtures.
- Leaking roofs, windows, or doors.
- Faulty gutters or downspouts that pour water into the foundation.
- Poor drainage around the property allows water to collect around the foundation.
Moisture and lack of ventilation, in which humidity accumulates inside places, such as the basement and attic. After identifying the source of moisture, a mold inspector will advise ways to correct the problem. Mold only stops growing when the cause of moisture is eliminated.
7. Type of Mold
Mold inspectors also identify the species of mold within a house. There are various species of mold, which some are more dangerous than others. For example:
Aspergillus: One of the most common mold species that occurs indoors and leads to respiratory problems.
Cladosporium: It lives on walls, carpets, and fabrics and often acts as an allergen.
Stachybotrys: Commonly known as “black mold,” this has significant health risks and causes critical respiratory disease.
Some mold species produce mycotoxins, which can be toxic to human health, especially in large amounts or prolonged exposure. Therefore, knowing the type of mold present will help identify the severity of the situation and whether special remediation methods are required.
8. Structural Integrity of the Property
Mold can structurally weaken a property extensively after some time. Mold inspectors gauge the extent of mold damage to wood, drywall, insulation, and flooring materials. Once mold attacks the wood and drywall, it may continue rotting and crumbling the surfaces.
The inspector will look for signs of damage to these materials, such as warping, staining, or soft spots. If the mold has caused severe damage, the inspector may recommend replacing the affected materials to prevent further deterioration and ensure the property remains safe and stable.
9. Ventilation Systems and Ductwork
Mold can travel through a house through the HVAC system, particularly if mold spores are in the ducts. A mold inspector will check the ventilation system, including air ducts, vents, and air filters, to ensure that none of these are mold-contaminated. Mold can grow inside the ducts with enough moisture, which can be circulated throughout the house when the system is on.
The inspector will look for any visible mold growth inside the ducts and musty smells that can signify the presence of mold spores. If mold is detected inside the HVAC system, professional cleaning and remediation of the ducts may be necessary.
Conclusion
Inspection is important in detecting, analyzing, and mitigating a property’s mold problems. In carrying out this process, the inspector visually inspects visible mold growth, water damage, hidden mold, air contamination, and the source of moisture through the application of special equipment and moisture detectors in combination with air quality testing. He can then decide upon remedial action based on this observation.

A mold test tells you about mold spores in your indoor environment, assessing air quality, moisture levels, and visible growth. It identifies the presence of allergens, fungal species, health implications, and water damage and suggests remediation options for a healthier space.
How to Prepare for a Mold Inspection?
Prepare your space for a mold inspection by cleaning it thoroughly. Focus on health risks and find where moisture comes from. Use ventilation and prevention methods. Look for common signs of mold and think about handling it yourself. Keep safety measures in mind, and get professional help for long-term problems.
