A thorough mold inspection from Home Enviro involves far more than just a visual check. Our experienced technicians use a combination of advanced techniques and specialized equipment to identify not only visible mold growth but also hidden mold issues that could degrade your indoor air quality. Moisture meters detect dampness in walls and floors that can allow mold to flourish. Thermal imaging cameras identify moisture issues invisible to the naked eye. Air testing and surface sampling are used to trap mold spores for lab analysis by Home Enviro. This determines the exact mold species present and if dangerous levels are reached. The right inspection tools and testing methods are essential for finding all mold problems, even those hidden from view. Our comprehensive inspections give homeowners the full picture so that proper remediation plans can be made. Trust Home Enviro's expertise in all aspects of mold inspection.
Mold testing is a critical step in identifying the presence of mold and assessing the potential risks it poses to indoor air quality and occupants' health.
It's essential to address mold-related issues promptly and seek the expertise of a professional mold inspector if you suspect mold growth in your home or business.
Post-remediation verification is a critical step in the mold remediation process, providing validation and confidence that the property is mold-free and safe for reoccupation.
The most common method uses a "spore trap" and is called a "spore trap sample." Spore traps work by having a known volume of air pass impact a sticky surface as it passes through the spore trap sampling device. Most of the particles in the air also impact this sticky surface and consequently adhere to and are captured on this sticky surface. Mold spores comprise a subset of these 'particles in the air and are captured on the sticky medium inside the spore trap.
Surface samples can be taken in a variety of ways. The three most common methods are:
A piece of the sampled area is physically removed and sent to the mold testing laboratory.
Something akin to a cotton swab is rubbed across the area being sampled, often a measured area, and subsequently sent to the mold testing laboratory.
A piece of clear tape is pressed against and removed from the area being sampled, presumably picking up and removing part of any mold that was present on the surface, and then set to the mold testing laboratory for analysis.
ERMI Mold DNA Testing
ERMI testing uses DNA analysis to identify the mold species. The collected dust samples are analyzed using a technique called quantitative polymerase chain reaction (qPCR), which amplifies the DNA of mold spores present in the samples. This allows for the identification and quantification of specific mold species.
Visible mold growth in an AC system warrants thorough investigation and testing. Here are some key reasons why comprehensive mold testing is so crucial in this situation:
Visible mold growth warrants a full inspection using testing, sampling, and analysis to determine the true extent of contamination. This ensures proper remediation to eliminate health hazards, prevent spread and recurrence, and confirm the system is restored to a clean state after treatment.

Mold growth in HVAC ductwork is a common issue that arises when two key enabling factors are present - moisture and warm temperatures. Moisture accumulation happens when humidity levels inside the ducts are high, leading to condensation on interior duct surfaces, especially if there is temperature variability. Any water intrusion from leaks or external flooding can also introduce moisture. This moisture allows mold spores, naturally present in indoor air, to land on duct surfaces and propagate rapidly. Warm temperatures between 60-80°F, which are typical in ductwork, accelerate mold growth. The combination of moisture and warmth creates an ideal breeding ground for mold. Once established, mold colonies release more spores that spread through the home when the HVAC runs. This degrades indoor air quality and can cause health issues if occupants have allergies or asthma. In addition, mold buildup physically blocks airflow and reduces HVAC system efficiency. This results in higher energy bills and potential damage to HVAC components. Regular inspections, moisture control, and quick remediation are required to prevent extensive mold infestation within the ductwork.
Here are some additional points about appropriate situations and goals for mold sampling:
Outdoor air sample
Water intrusion into walls and roofs is a very common problem that can lead to mold growth and structural damage if left unchecked. Sources of water intrusion include roof leaks, poor drainage and gutter overflow, moisture condensation, plumbing leaks, and flooding or heavy rain events. Water intrusion can happen slowly and out of sight, causing wet walls, insulation, and wood rot. Signs include peeling paint, musty odors, and moisture spots on ceilings and walls. If you suspect water intrusion, it is critical to have a professional mold inspection. The latest moisture meters and thermal imaging can detect excess moisture behind walls and ceilings that you cannot see. Identifying and fixing the source of water is key before mold flourishes and causes health hazards. Don't ignore signs of water intrusion. A mold inspection can determine if your home's hidden areas have a damaging moisture issue.

Do you are concerned about indoor air quality and potential allergens in your home or workplace?
ERMI (Environmental Relative Moldiness Index) testing and air quality sampling are two different methods of testing for mold in a building.
ERMI testing involves collecting dust samples from a building and analyzing them for the presence of mold DNA. The results are used to calculate an ERMI score, which indicates the relative amount and types of mold species present in the building. ERMI testing is often used to provide a broad assessment of mold in a building and to identify potential health risks associated with mold exposure.
Air quality sampling, on the other hand, involves collecting air samples from a building and analyzing them for the presence of mold spores. The results provide information about the concentration and types of mold spores present in the air. Air quality sampling is often used to assess the current level of mold spores in a building and to determine if remediation efforts have been effective in reducing mold spore levels.
Both ERMI testing and air quality sampling can be useful in assessing mold problems in a building, but they have different strengths and limitations. ERMI testing provides a more comprehensive assessment of mold species present in a building, while air quality sampling provides information about the current level of mold spores in the air. Both methods can be useful in developing an effective remediation plan and monitoring the effectiveness of remediation efforts.
It's recommended to work with a qualified mold inspector or remediation professional to determine the most appropriate testing method for a specific building and to interpret the results accurately.
Doctors may request an Environmental Relative Moldiness Index (ERMI) testing for several reasons when evaluating a patient's health and symptoms, especially if there is suspicion of mold-related illness or exposure. ERMI testing is a comprehensive method for assessing the presence and types of molds in indoor environments.
