Mold 101

Mold 101

Mold is a type of fungus that is ubiquitous in nature and thrives in moist, humid environments. Mold can grow rapidly, sometimes within 24-72 hours after a moisture intrusion in a favorable environment. Mold can grow on virtually any organic-based building material, textile, or personal belonging. Even if there is an inorganic item, such as glass or metal, mold can still grow on the organic dust that settles on its surface. As a microorganism, mold is as impressive as it is destructive.

Mold is one of the top degraders of cellulose on the planet! While this is beneficial for our outdoor ecology, it can weaken the structural integrity of our homes or offices in the event of a contamination issue. Types of mold, like Serpula lacrymans, commonly known as the wood rot fungus, can destroy solid wood beams, rendering the property’s structure unsafe.

Mold growth in a home or office is often a symptom of a moisture problem. Moisture issues can be obvious, such as a leak or flood, but can also be subtle, such as elevated indoor relative humidity levels, condensation caused by inadequate ventilation, or unidentified air leakage points. There can be more than one source issue for a mold contamination problem, and having an experienced, laboratory-approved mold professional assess your concerns can provide an inordinate amount of helpful data to keep everyone safe.

Mold survives by reproducing through tiny spores that are invisible to the naked eye and easily dispersed through the air. Once these microscopic spores land on an organic substrate, they can begin the growth process anew, especially if there’s moisture or elevated humidity levels within the environment. Mold spores can only be identified through an analytical process that includes proper sample collection by a trained professional, followed by microscopic examination by a certified microbiologist. There are hundreds of thousands of different species of mold, some of which are known to be toxigenic. However, all molds are allergenic and carry the potential to impact one’s health, particularly for individuals with pre-existing sensitivities, allergies, or compromised immune systems.

Why Is Mold Testing Important?

Why Is Mold Testing Important?

Mold testing is important for accurately identifying the types of mold present and their concentration levels. This data can help individuals, in consultation with their physician, understand the impact of their indoor air quality as it relates to their health symptoms.

A common misconception is that one needs to know the type of mold present in order to establish a remediation or decontamination plan. This is a clever marketing strategy but is scientifically false. Health Canada recommends “controlling dampness indoors and cleaning up any visible mold regardless of the type of mold present.”

However, mold testing is especially important in cases where there is no visible evidence but suspected contamination due to musty odors, hidden water leaks, or mysterious health symptoms. Axxonlab’s mold testing service involves a trained professional using advanced equipment for air and surface sample collection, real-time diagnostic measurements, and microscopic analyses by microbiologists at our reputable laboratory. Early detection through mold testing can prevent costly damage and health complications. Mold testing is also important for providing peace of mind, ensuring that an environment has been properly remediated, or confirming that it contains an acceptable indoor fungal ecology.

Signs Of Mold Contamination

Signs Of Mold Contamination

Signs of mold contamination can range from visible growth, often appearing as fuzzy patches in black, green, yellow, or white, to subtle indicators like a persistent musty odor or the presence of silverfish or other organisms. Moisture is the problem, mold is a symptom. A hidden mold contamination issue may be present, especially with unresolved or unidentified water intrusions.

Health symptoms such as coughing, sneezing, eye irritation, and skin rashes, especially when they worsen in a particular environment, can also be indicative of mold contamination. The risk level is influenced by the amount of mold growth, the duration it has been present, and the health and susceptibility of the individuals exposed, regardless of the mold species. Certain groups, including infants, seniors, pregnant individuals, and those with respiratory issues such as asthma, are more likely to experience negative health effects from mold exposure.

If you notice any of these signs, it’s recommended to seek professional mold testingto confirm or deny a hidden fungal contamination issue.

What Are Mold Spores?

What Are Mold Spores?

Spores are microscopic particles that mold releases in order to reproduce. These spores are lightweight and can become airborne, making them easy to inhale and capable of traveling significant distances. Mold spores become airborne when they are disturbed by activities such as cleaning, construction, or even a breeze from an open window.  Once they land on a suitable surface with adequate moisture and nutrients, they can grow into new mold colonies. They can persist in the air even after the visible mold has been removed. To identify the type and concentration of mold spores present in your indoor environment, professional microscopy by a certified microbiologist is recommended once air or surface samples have been collected by a sampling technician.

How Do Mold Spores Affect Your Health?

How Do Mold Spores Affect Your Health?

⬡ When a person breathes in mold spores, these microscopic particles enter the respiratory system through the nose and mouth.

⬡ Spores will first encounter the mucous membranes in the nasal passages, which can trigger an immune response in sensitive individuals, causing symptoms like sneezing, congestion, and runny nose.

⬡  Spores may then travel down the respiratory tract, irritating the throat and trachea, often causing coughing fits and a sore throat.

⬡ Mold spores can reach the bronchi and bronchioles, the smaller airways in the lungs, causing inflammation and irritation. This can lead to bronchitis-like symptoms, such as persistent coughing, wheezing and lightheadedness.

⬡  Mold spores spores can also reach the alveoli. These are the tiny air sacs in the lungs where gas exchange occurs. This can cause more severe respiratory issues, especially in people with pre-existing conditions like asthma, emphysema or chronic obstructive pulmonary disease (COPD).

⬡ Your immune system may recognize mold spores as foreign invaders and produce antibodies to fight them. This can trigger allergic reactions, such as sneezing, skin irritations, watery eyes, and increased asthmatic reactions.

⬡ Prolonged exposure to mold spores can lead to hypersensitivity pneumonitis, an inflammatory condition of the lungs, especially for infants, the elderly, individuals with compromised immune systems or pre-existing sensitivities to mold and allergens.

Early and accurate detection through professional mold testing is recommended if you believe you are experiencing symptoms related to mold spore exposure. Remember, you don’t have to see spores for them to be present. Contact our team today to learn how our renowned laboratory services can provide you with unbiased, data-driven insights.

Preventing Mold Growth

Preventing Mold Growth

Preventing mold growth first involves controlling moisture and maintaining proper ventilation in your home or workplace. Ensure that leaks and water damage are repaired promptly, and use dehumidifiers in damp areas like basements. Humid environments, such as unfinished basements ought to be cleaned often, ensuring any settled dust is removed from surface areas, as this is a premium food source for mold.

Regularly clean and inspect areas prone to moisture, such as around sinks, showers, windows, roofs and the perimeter of foundation walls.

Ventilation improvements, such as using exhaust fans in kitchens and bathrooms, or adding an air exchanger to your mechanical ventilation system can also help reduce humidity levels, which is important for mold prevention.

Frequently Asked Questions

01. If I see black mold in my home, does my family have to move out?

First, it’s important to note that “black mold” is generally meant to describe a particular species called Stachybotrys chartarum. This “toxic black mold” has been sensationalized in the remediation industry and many misleading articles have been written about its effects on human health.
Second, Stachybotrys chartarum can be a number of colors, such as gray or green, depending on its sporulating phase, the substrate (building material) it’s growing on and the type of moisture content present. Additionally, there are hundreds and hundreds of mold species that appear black in color. Most often, the “toxic black mold” that people believe they have growing in their home is non-toxigenic and can belong to a number of ubiquitous mold types.
Last, professional mold testing provides a wide array of data that can help determine the appropriate course of action. There are many factors to consider when recommending vacancy of a property and often involves multiple professionals to make that call.
Axxonlab’s position is one rooted in the scientific process, void of sensationalism, and based on verifiable data. We will guide you through this process and help ensure you receive honest, accurate and helpful insights to any mold issue.

02. I have a report from a mold removal company, but I want a second opinion. Can you do this?

Yes, absolutely! Axxonlab has been providing second opinions and consultations on existing reports and lab results for over a decade. Several of our team members are recognized as expert court witnesses for environmental and analytical cases, regularly lending their experience and practical training to shed accurate insights on mold or asbestos reports.
If you are doubting the claims made in a recent mold or asbestos assessment, or simply want a more detailed, unbiased, scientific interpretation of laboratory results, we welcome you to book a consultation with one of our experts today.

03. My office has had many roof leaks over the years and I'm only sick when in the office. Do we need mold testing?

Indoor mold growth is the symptom of a moisture issue. If your office has had many leaks the conditions conducive for fungal development may exist. Sick Building Syndrome (SBS) is a condition where people experience various symptoms of illness or discomfort that seem to be linked directly to spending time in a particular indoor environment, like an office, or other workplace. These symptoms typically improve or disappear when affected people leave that building. Visible black mold growth on walls or ceilings is not necessary for a mold issue to be present. In fact, most of the spaces we assess have no visible signs of mold growth at all! Axxonlab’s mold testing services include sampling the air for microscopic mold spores. You cannot see mold spores with the naked eye (unless you have superpowers, in which case, please send your resume ➡ here).
This type of mold test can provide incredible insights into the particulates you may be breathing in while at the office, and together with your physician, can help determine if it’s directly impacting your health.

04. If there's mold in my house, is it enough to clean it with vinegar or bleach?

Household cleaning products like bleach or vinegar can be used to clean light mold growth on non-porous surfaces, such as ceramic, metal, or glass. However, bleach and vinegar are ineffective products when trying to effectively remove significant mold growth, especially on porous surfaces like drywall, wood, or textiles.

Mold has a very complex cell wall.
The basic backbone of the cell wall is chitin (the same substance that makes up lobster shells). It is very hard. This is why professional fungicides are the preferred products to use as they are engineered to penetrate the complex and fortified cell structures of fungus.

When bleach (sodium hypochlorite) is applied to moldy, porous materials (e.g., drywall), the mold may initially disappear but often reappear within weeks. Bleach eliminates surface organic matter, but the mycelia beneath the surface remain unaffected and mold will subsequently regrow.
Bleach cannot penetrate the material and reach the mycelium. Bleach can exacerbate the situation by introducing additional moisture. The water from the bleach solution can be absorbed by the material, providing nourishment to the mycelium without eradicating it.

Although household vinegar is mildly acidic and can inhibit mold growth to some extent, it is not potent enough to kill all types of mold, especially more resilient species. Vinegar may not kill the entire mold colony or eliminate the spores, which means mold can quickly return if environmental conditions are favorable.

Both products – bleach and vinegar – contain a lot of water. For example, in a bottle of bleach, there may be only 3-5% of sodium hypochlorite, while the rest is primarily comprised of H20.
Water is the problem; mold is the symptom.

All mold issues ought to be assessed by a professional to determine the most effective remediation protocol. Contact us today for a comprehensive assessment.

05. If there's visible mold, does that mean the air in my house is also contaminated?

Visible Mold:
Indicates active mold colonies.
Spores are released into the air as part of the reproductive/survival cycle.
Airborne spores spread throughout the environment, settling on surfaces or inhaled.
Potential health issues from inhaling spores.
Spores can settle and cause new mold growth, impacting the integrity of building materials as mold is a degrader of cellulose.

No Visible Mold:
Mold can be hidden (behind walls, under flooring, or even in HVAC systems).
Hidden mold still releases spores. Spores are microscopic particles. Imagine the size of a cotton ball as a large beach ball. One mold spore, in comparison, would be smaller than a tiny grain of sand next to that beach ball. They can pass through porous materials, cracks and pathways very easily.
High humidity or water damage can promote mold growth and initiate spore release.
An absence of water or nutrients can also activate a survival mechanism in mold, causing spores to be released.
Airborne spores, when inhaled, can potentially impact one’s health.

A professional mold assessment that includes air quality testing can detect the presence, type and concentration of mold spores present, regardless of whether mold is visible or not.

06. What's involved in a mold assessment?

Axxonlab’s mold assessments involve dispatching one of our lab-approved environmental sampling technicians to collect data from the areas of concern in an unbiased and scientific fashion.
We collect a variety of air and surface samples along with a full range of real-time diagnostic measurements of temperature, relative humidity and carbon dioxide (CO2) levels. Every sampling technician is equipped with thermal imaging cameras and moisture meters to help further understand current indoor environmental conditions that may be conducive to fungal development.
A standard residential mold assessment can take up to an hour to perform, and every aspect of the assessment is photographed for the report.
All collected samples are then analyzed in our laboratory by our team of certified microbiologists, undergoing rigorous quality control to ensure accurate data for you. We aim to have the full report completed and in your hands within 24-hours following the site visit.
Our dedicated laboratory support team is always available to walk you through the report – line by line – to help interpret the results and prepare you for any recommendations we have made.

07. Can your lab do ERMI or HERSTMI-2 tests?

ERMI (Environmental Relative Moldiness Index) is a DNA-based method developed by the U.S. Environmental Protection Agency (EPA) to assess mold contamination in homes.
It quantifies the presence of 36 mold species commonly found in water-damaged buildings.

HERTSMI-2 (Health Effects Roster of Type-Specific Formers of Mycotoxins and Inflammagens – 2) is a subset of the ERMI test, focusing on five specific mold species known to be highly associated with water-damaged buildings and significant health risks. Similar to ERMI, dust samples are collected and analyzed using qPCR for the five mold species. The results are used to calculate a HERTSMI-2 score, which helps assess the potential health risks related to mold exposure.

There is ongoing scientific debate about the interpretation of ERMI and HERTSMI-2 scores.
Some experts question the accuracy and reliability of these indices in predicting health outcomes or mold-related issues.

The ERMI and HERTSMI-2 tests have not been widely accepted or standardized in the mold assessment industry.

We currently do not offer or support ERMI/HERTSMI-2 testing or analytical services.

Axxonlab’s comprehensive mold testing service adheres to current industry standards and remains the most reliable and acceptable methodology for fungal assessments.

08. Does your mold assessments include VOC testing?

VOC (Volatile Organic Compound) testing is generally not included in Axxonlab’s standard, comprehensive mold assessment service.

VOCs are a large group of organic chemicals that easily evaporate at room temperature and are emitted as gases into the air from certain solids or liquids.

Mold spores are microscopic, solid, airborne particulates. Mold is a microorganism and part of fungi’s incredibly diverse kingdom.

Although both are related to indoor environmental sciences, the methodologies to sample each vary significantly from one another.

Axxonlab offers an enhanced mold assessment option for those who want to include TVOC (Total Volatile Organic Compound) counts, PM 2.5 and PM 10 (particulate matter) readings, and instant CH2O (formaldehyde) detection. This enhanced mold assessment is particularly beneficial for environments with recent renovations that include new cabinetry or countertops, or where an odor issue is the predominant concern. Connect with us today to learn more about our enhanced mold assessments and how our lab-approved environmental sampling technicians can help you.
