Stachybotrys molds decay organic matter. The most common species, Stachybotrys chartarum, sometimes referred to as Stachybotrys atra often grows indoors.
Ideal conditions for Stachybotrys growth include moisture, a nutrient/food source, temperature, and time. Ideal humidity for this black mold is a relative humidity of 90% or higher for it to begin the germination growth process. Stachybotrys feeds on materials with a high cellulose content such as hay, straw, wood chips, and building materials such as ceiling tile, drywall, paper vapor barriers, wallpaper, insulation backing, cardboard boxes, and paper files.
Stachybotrys Is The King Of Molds!
Stachybotrys Is The King Of Molds!
Stachybotrys is considered the King of Molds because it will develop into the dominant mold group if the conditions are favorable and will crowd out the other molds that began feeding on the material first.
This happens because unlike other molds like Aspergillus, Penicillium, and Cladosporium which begin growing within one to two days, Stachybotrys takes one to two weeks to begin growing.
How Does Black Stachybotrys Mold Spread?
How Does Black Stachybotrys Mold Spread?
When Stachybotrys mold is growing on wet material, the spores do not disperse as easily because the spores are held together by a sticky/slimy coating. However, when the material dries out or is disturbed, the spores will spread through the air.
The main concern of a mold remediation contractor is to prevent the spread of toxic black mold. The most effective method of doing this is through containment, which is the process of creating a poly barrier around the area where the Stachybotrys mold is growing.
This procedure is so important because Stachybotrys spreads by releasing spores. Mold contaminated materials must be removed and disposed of because this mold does not just grow on the surface of the material; it has root-like tendrils called mycelia, meaning it is able to penetrate the surface.
Typically Stachybotry mold grows in clusters at the end of stem-like structures known as hyphae.
Top 15 Health Problems Caused By Stachybotrys Black Mold!
Top 15 Health Problems Caused By Stachybotrys Black Mold!
Stachybotrys black mold is a health concern because animal studies have shown that one of the major effects of trichothecenes is immuno-suppression.
In fact, even low level exposure can suppress the immune system resulting in bacterial and viral infections, coughing, skin irritation, and other allergic reactions, and there is some speculation that it may even cause cancer.
Listed below are the top 15 health conditions caused when toxic Stachybotrys black mold is inhaled or ingested:
Sore/hoarse throat
Cold and flu symptoms (headaches, slight fever, and muscle aches)
Nosebleeds
Tingling or burning of nose, mouth, and perspiration areas (under the arms or between the legs)
If you have a roof leak, you may see water on your floors and water stains on the ceiling. The good news, you know that you have a problem.
However, if you have a roof leak and it goes unnoticed leading to moisture accumulation in your attic, this will eventually lead to mold growth that you may not even know exists.
This is the reason it is important to inspect your attic several times each year, just to make sure that there is no moisture buildup.
Check for discoloration of insulation and wood (e.g. rafters, sheathing, joists, attic side of fascia boards, etc.).
Check roof valleys (i.e. where two roofs join at an angle), which are highly susceptible to roof leaks.
Observe skylights, chimneys, attic windows and any portion of the attic/roof where dissimilar materials join each other (including flashings). These places are hotbeds for potential moisture intrusion.
If you have a vapor barrier installed, check for condensation. Although this is not really a roof leak, it is nevertheless a sign of a moisture problem. And moisture problems lead to attic mold problems!
Make sure there are no leaks coming from and around attic plumbing stacks.
The first step to addressing the moisture cause is to get your roof repaired, then call us to remove the mold.
#2 Missing Insulation or Improperly Installed Insulation
The quest to save money on heating and cooling bills motivates many Do-It-Yourselfer’s to install more insulation in their attics.
Unfortunately, if the wrong kind of insulation is chosen or if it is installed improperly, this can cause moisture from the lower levels of your home to rise and get trapped in the attic.
As we have written before, the primary cause of mold growth is moisture. Your attic is made of the food mold loves to feed on.
With respect to the type of insulation, if you are layering insulation on top of other insulation, make sure you do not use the kind that has paper or foil backing because it acts as a vapor barrier and can trap moisture in the insulation.
Before you decide to add more insulation to your attic, determine if you need more first. If you are unsure, contact a professional.
#3 Inadequate Attic Ventilation
One of the problems we have encountered in our projects is the fact that insulation is blocking the ventilation ducts that distribute air in the attic.
The lack of ventilation is another major cause of mold growth in your attic.
Air travels up to the attic meaning activities such as cooking, bathing, showering, etc will produce moisture that will makes it way up to the attic. If there is poor ventilation, the moisture gets trapped in the attic and can lead to mold problems.
Check your soffit vents and make sure they are free of insulation, bird nests, and other debris that could be blocking them and preventing proper air flow.
If you are unsure if the ventilation is ideal in your attic, contact a home inspector or give us a call so that we can take a look.
#4 Fans Vented Into The Attic
Mold will grow if there is moisture, food, and warmth.
Poor building practices occur when the dryer vents, plumbing vents, kitchen or bathroom fans are vented into the attic.
Dryer exhaust vents, kitchen exhaust fans and bathroom exhaust fans are designed to pump moisture out of your home. Make sure that they are vented to the outside of your home and not in the attic.
Plumbing stacks in the attic can also be a source of condensation, which can lead to attic mold growth. Plumbing stacks can also emit hazardous gases, so make sure that they too do not terminate inside the attic.
If any of your vents are routed into the attic, hire a reputable contractor to re-route the vents to the outside of your house.
Got Attic Mold Questions?
Once the cause of your attic moisture issues are identified, then the next step is to determine if you have a mold problem.
Mold is nature’s recycler and will grow and proliferate when moisture is present.
Condensation in an attic, heat and humidity from household activities (cooking, showering, etc.), and the fact that the attic provides an excellent food source for mold, provides the ideal conditions.
All mold needs to grow is 24 to 48 hours and as long as the proper conditions exist, it will continue to proliferate.
If you do find mold in your attic, DO NOT use bleach or try to kill the mold!
During the inspection, tape or swab samples of suspected mold may also be taken and sent to a micro-biology lab.
Once the type of mold and spore count is determined, we will provide with a scope of work on the best way to remediate the mold in your attic.
If you suspect that you may have mold in your attic or other areas of your home or business, call 678-697-6267 or send us an e-mail. We look forward to serving you! 🙂
Mold spores are all around us, outside and indoors. Mold actually serves a purpose in our eco-system to consume dead organic materials.
Problems with mold arise indoors primarily because our homes are made of dead organic materials, meaning mold can grow anywhere in your home: on carpet, clothing, food, paper, and even in places you can’t see, such as the backside of drywall, areas inside walls around leaking or condensing pipes, and above ceiling tiles.
The simplest way to detect a mold problem is using your own senses. A musty odor is one indication. Not only is mold smelly, but can be many different colors from black and gray to orange and green. Watermarks on the ceiling and walls are also a telltale sign.
There are two key reasons, you should be concerned about preventing mold.
First, mold can be difficult and costly to remove.
Second, mold can produce allergens, irritants, and mycotoxins that can compromise your health. Because mold spores are very small and can easily be inhaled into the lungs, it is harmful to live in a home with high mold levels.
Mold Can Compromise Your Health
Mold growth can be prevented. Mold growing in your home requires moisture, warmth, and food. Depriving mold of any of these three items will stop it from growing, but it will not kill the mold that is already there. Mold spores will remain dormant, and if the moisture, warmth and food all reappear, mold will begin to grow again.
So what can you do if you’re concerned about mold growing in your home?
Listed below are the top 15 mold prevention tips.
The Top 15 Mold Prevention Tips
Mold Prevention Tip #1: Audit Your Home For Problem Areas!
It is difficult to mold-proof a home. However, you can take proactive steps to determine if you have problems that could lead to mold concerns.
Does the basement flood?
Do you notice frequent condensation on windows?
Is there a water stain on the ceiling from a persistent leak?
Is your basement damp?
Does water flow into your home’s foundation?
Addressing these questions may entail some upfront costs to fix, but it will be worth the investment in preventing future mold problems.
It is also important to note that if you are renovating your home or considering building a new home, that you may want to consider researching mold prevention products, including mold-resistant drywall and sheetrock, and mold inhibitors for paints.
Mold-resistant drywall is recommended because traditional drywall is made up of gypsum plaster core pressed between piles of paper, making it highly susceptible to mold. What this means is that in the presence of moisture and water, traditional drywall acts like a sponge absorbing the moisture leading to mold. Since traditional drywall is so porous, the only remedy to removing the mold is to tear out the drywall.
In contrast, mold-resistant drywall is paperless because the gypsum core is covered in fiberglass, meaning it is water-resistant and therefore less susceptible to mold growth. Moisture resistance drywall should be used in bathrooms, laundry rooms, basements, and kitchens because these areas of the home are most prone to moisture.
Mold Prevention Tip #2: Dry Wet Materials Immediately!
Mold can not grow without moisture and given the right conditions, it will begin growing within 24 to 48 hours.
With this in mind, tackle we areas right away.
Don’t leave wet clothes or other items lying around the house, dry them outside if possible.
Dry spills on carpet and floors.
Dry your clothes after washing them by putting them in the dryer soon after the wash cycle is complete.
If heavy rainfall causes seepage into your basement, make sure you dry the area promptly and contact a company to waterproof your basement to prevent future occurrences.
If you experience a flood event, dispose of water-damaged carpets, bedding, and furniture if they can not be dried completely. Ideally, contact a restoration company to manage the clean up and drying process.
Mold Prevention Tip #3: Clean, Disinfect, and Dry Surfaces!
Vacuum and clean regularly to remove possible sources of mold growth.
Pay special attention to bathrooms and other areas of your home that are likely to generate a lot of moisture.
Non-porous surfaces (tile, stone, laminate) can be cleaned well with disinfectants and other cleaners.
Mold Prevention Tip #4: Repair Water Leaks!
Repair water leaks in your roof, windows, or any other part of the home as soon as possible.
Over time, constant leaks will cause moisture to buildup leading to mold growth.
Mold Prevention Tip #5: Use Area Rugs!
In portions of your home that are susceptible to moisture, use area rugs or washable floor surfaces rather than wall-to-wall carpeting. If you use area rugs, launder them periodically.
Mold Prevention Tip #6: Increase Air Flow!
Prevent moisture buildup by increasing the air flow within your home. Without good air flow, excess moisture can appear on your walls, windows, and floors.
To increase air circulation, open doors between rooms, move furniture away from walls, and open doors to closets.
In addition, open windows to allow fresh air to flow indoors.
If you don’t already have an HVAC system that has an outside air intake to bring in a steady stream of outside air, consider installing one.
Mold Prevention Tip #7: Proper Ventilation!
Routine daily activities such as cooking, taking a shower, and washing laundry can create excess moisture in your home.
Prevent moisture with proper ventilation.
Vent appliances that produce moisture (clothes dryers and stoves) to the outside, not to the attic or crawl space.
Use AC units and dehumidifiers (especially in humid climates), but make sure they don’t produce moisture themselves by checking them periodically and cleaning them as directed by the manufacturer.
Energy-efficient homes are prone to holding moisture inside. For this reason, it is important that you open windows or use exhaust fans in the kitchen and bathroom (especially when you are showering).
Mold Prevention Tip #8: Make Sure Your Storage Room Is Dry!
Most homeowners have a room where they store materials such as books, clothes, camping gear, and other occasional use items.
It is important that you check the humidity of your storage room and make sure that there is no excess moisture because most of the materials you are storing are ample sources of food for mold.
Ideally, use your garage, a well built shed that prevents moisture intrusion, or a dry storage unit and not the inside of your home. Make sure there is air circulating in the storage area as well.
Mold Prevention Tip #9: Control Humidity!
Clues that your home has excess humidity include condensation on windows, pipes, and walls. If you notice condensation, dry the surface immediately and address the source of moisture, and invest in a dehumidifier if necessary.
To measure the humidity levels in your home, purchase a moisture meter from your local hardware store.
Ideally, the indoor humidity of your home should be between 30 and 60 percent.
In the winter, it is recommended that humidity levels are below 40 percent to prevent condensation from appearing on the windows.
Mold Prevention Tip #10: Check Your Attic!
Make sure that your exhaust fans are not venting into the attic because this will create excess moisture and lead to mold.
Also, your attic needs ventilation as well, so check this.
Insulation is important, particularly in cooler climates because snow accumulation on the roof can lead to ice damning issues which will cause moisture issues.
Mold Prevention Tip #11: Check Your Crawl Space!
Most homes in the Southern United States have crawl spaces.
Crawl spaces are a breeding ground for mold because there is so much excess humidity.
Mold growth in the crawl space is a particular concern because it will also impact the indoor air quality of your home.
If you find excess moisture or mold issues in your crawl space, then the area should be cleaned properly and the mold removed. To prevent future mold issues, wall-to-wall guide, durable, 14 mil vapor barrier should be installed over the ground and up sidewalls to 6 inches below floor joists. Installation of a dehumidifier will also help control humidity.
Mold Prevention Tip #12: Prevent Basement Condensation!
The cool basement floor and walls can be a source of moisture build-up, leading to mold and that musty smell many encounter in their basements.
To prevent condensation and future moisture issues, improve air circulation, run a dehumidifier, and install a foundation drain.
Ideally, make sure the basement walls are insulated properly to keep the walls warm and limit condensation.
As a final note, if you find that there is moisture intrusion into your basement through seepage, consider hiring a contractor to water proof the area.
Mold Prevention Tip #13: Direct Water Away From Your Home!
One of the best methods to prevent seepage into your crawlspace or basement is to ensure that water around your home sufficiently slopes away from the foundation of your home.
Do not put gardens or plants too close to your foundation so that watering them could cause water to flow toward your house.
If you water your lawn with a sprinkler, make sure the water does not hit your house or the area next to the foundation.
Mold Prevention Tip #14: Keep Your Gutters and Downspouts Clear of Debris!
Debris in your gutters or downspouts could block the flow of water from your roof. To prevent water accumulation, clean your gutters regularly and have them inspected for damage. It is also a good idea to check your ceiling for water stains, particularly after heavy storms.
In addition, make sure the area under your downspouts is properly graded so that rainwater from the roof flows away from your foundation. If the water is not flowing away from the foundation, extend your downspouts.
Mold Prevention Tip #15: Check Your Plants For Mold!
Plants help keep your indoor air clean. Unfortunately, mold grows in the soil of house plants and can also grow on the leaves, leading to higher levels of mold spores in the home. To hinder mold growth in plant soil, add some Taheebo tea to your house plant water in a mild solution. The oil of this tree, which withstands fungi even in rain forests, helps hinder mold growth in plant soil and can be found at natural food stores.

Top 10 Tips To Prevent Basement Mold!
Top 10 Tips To Prevent Basement Mold!
Fix The Flooding Source!
The first step to preventing future flooding is to determine the cause and fix it. Most basements flood because of backed up drains, leaky pipes, human error (i.e. leaving a tap on), sewer back ups, the lack of a sump pump and/or a malfunctioning sump pump.
Start The Clean Up As Soon As Possible!
The onset of mold will begin within 24 to 48 hours, so it is essential that you begin the clean up immediately.
Hire Experienced Professionals!
If mold is not properly contained and cleaned properly, it can become airborne and contaminate even larger areas of the property.
You need to hire properly trained professionals, like Mold B Gone, who understand how to properly restore a water damaged property and prevent mold growth. Mold growth prevention is important because of the health impact it has and also because mold will impact the structural integrity of the property.
Remove All Wet and Contaminated Materials!
Most insurance companies will not recommend a complete gut for cost savings. Usually they recommend that it is necessary to only remove one foot of drywall above the flood line.
We do not because this could result in long term mold problems because moisture can creep up behind the surface. For this reason, we recommend a complete gut of the basement because the extra short term cost could result in significant long term cost savings.
The last thing you want to happen is for a reconstruction to occur only to find out six months later that you now have a mold problem.
Removal of all the drywall is not our only recommendation. We also suggest the removal of following: all flooring, including the sub-floor; insulation because it absorbs moisture; and finally, if the electrical panel was submerged under water, it should be replaced as well.
“Perhaps the most misunderstood aspect of bleach when proposed as a cleaner or sanitizing agent is that its effectiveness is greatly reduced in the presence of organic material. To be a successful sanitizer, bleach must be used on clean materials and surfaces. This is why bleach products are used in the laundry after the wash cycle or in a commercial kitchen as a component in the third sink after the dishes have been washed and rinsed. The efficacy of bleach as a sanitizer is also compromised by heat and light. Despite the fact that the chlorine odor may linger for some time after use, bleach loses strength so quickly that it is not considered to have a residual effect that would prevent future bacterial or fungal growth.”
Do Not Begin Any Rebuild Until the Basement Is Completely Dried Out!
We understand that a flooded basement disrupts your life and you want to resume your normal routine as soon as possible. However, patience is the key.
In addition, if the flood water was category 3, we recommend that swab tests be performed to ensure that the cleaning process was done effectively.
Only after it is verified that the basement is completely dry and sanitized and clearance testing verifies that the indoor air quality is healthy should the basement rebuild begin.
Properly Insulate Your Basement!
According to Mike Holmes, a respected contractor, insulation is one of the most important factors in preventing basement mold:
“When air, which is full of moisture, leaks into that insulation, it will inevitably lead to mould. Here’s why: Your basement, like every room in your home, has its own natural air convection. The air nearest the ceiling is warmer, and the air nearer the floor is cooler. The cold air at the bottom pushes the warm air up. As it rises, it comes into contact with the cooler exterior wall and releases the moisture it’s holding. It condensates. That air and moisture — if it’s able to get into the batt insulation through a gap in the seal — will wick into the insulation. Over time, it will soak that batt to the point that water can drip down the walls and pool on to the floor….You need a thermal break to stop hot from meeting cold….So, use closed cell spray foam insulation or rigid foam insulation, which will provide a thermal break and not trap any moisture. If you’re using foam insulation boards, make sure you Tuck Tape every seam, and spray-foam all corners and joints to create a 100% seal and a perfect thermal break. That way, you’ll know that anything you do inside your finished basement won’t have to be torn out in a few years because of mould.”
Cross-Ventilate!
If possible, open the windows on all sides of your basement in the evenings when the air is cooler to create a cross-ventilation air flow which will prevent excessive moisture and also ensure that a steady stream of fresh air is circulating throughout the basement.
Ensure Water Drains Away From Your Home’s Foundation!
One of the most effective ways to prevent water intrusion is to ensure that water is not sloping towards the foundation of your home but away from it. This is particularly important if your basement walls are porous and can trap moisture, which can lead to mold. To avoid this, ensure that the ground slopes away from the foundation walls of the home and your downspouts extend at least 6 feet away from the property.
Invest In A Dehumidifier!
To prevent excess moisture in your home, use a dehumidifier and consider waterproofing your basement by sealing cracks in the floor and walls with hydraulic cement and a concrete waterproofing sealer where the floor meets the walls.
Crawlspaces are the ideal environment for mold to thrive.
Most crawlspaces are dark, dirty, and humid. Bugs like to live in there. They’re vented to the outside air in the summer (and in the winter if you neglect to close your vents) which can be very humid and this defeats the purpose of venting.
Mold is a fungus that requires moisture and high humidity to grow and thrive.
Like plants, mold has cells. However, unlike a plant that has chlorophyll and able to makes it’s food through photosynthesis, mold can not feed without moisture.
Mold reproduces by releasing it’s spores, this is mold’s survival mechanism.
In addition to moisture, mold also requires the right temperature of 41 degrees fahrenheit up to 100 degrees fahrenheit, common in Atlanta, Georgia and the South.
The final ingredient mold needs to thrive is food: high cellulose materials such as paper and wood, drywall, wallpaper, carpet, ceiling tiles, dust, and dirt.
Now that you understand why mold grows in your crawlspace, the remainder of this article will list and explain the top three reasons why you have moisture in your crawlspace and what you can do to fix the humidity issues.
How To Measure The Relative Humidity Of Your Crawlspace?
The easiest way to determine the relative humidity of your crawlspace is to use a hygrometer or you could install a digital thermo-hygrometer with a remote sensor to track it.
If the relative humidity is greater than 50% this could cause moisture issues that leads to mold.
Mold will begin to grow at 50%, and will thrive when the humidity is greater than 70%.
The key to ensuring that your crawlspace does not become a source of mold is to figure out how to control the humidity.
Listed below are the top three reasons your crawlspace has high humidity.
#1 Water Accumulation
If your crawlspace has standing water, you probably have a drainage problem or a plumbing leak. This needs to be fixed immediately.
You do not want water to accumulate in your crawlspace because this will compound your potential mold problems, not to mention as mold grows it will impact the indoor air quality of your home and health.
#2 Moisture Evaporating from the Ground
When homes are built with crawl spaces, most builders neglect to cover the ground, meaning that the crawlspace is covered with dirt.
Dirt has moisture and as the moisture evaporates, it will increase the humidity in your crawlspace.
Unfortunately, this is a common problem in Atlanta, Georgia, and other southern states. To prevent moisture from evaporating from the ground, the easiest solution is to cover it up with a vapor barrier during crawlspace encapsulation.
#3 Outdoor Air Coming in through the Crawl Space Vents
The third reason your crawlspace could have moisture issues is through the vents.
When you bring outdoor air into the crawlspace, the relative humidity can increase.
Cool air cannot hold as much moisture as warm air, so the air that enters is now closer to its saturation point, referred to as the dew point.
It might be 60% relative humidity outside, relative to a temperature of 90 degrees fahrenheit, but when that air enters the crawlspace and cools down to 75 degrees fahrenheit, the relative humidity jumps up to 95%.
In the past, we were told that crawlspaces needed to be ventilated. Now, however, we are learning that crawlspaces need to be treated almost as if they were living spaces. In other words, areas that are in contact with your living space affect your living space.
Fixing Your Crawlspace Humidity and Mold Problems
If your crawlspace is vented and the relative humidity is high, you need to fix the problems. It is not as simple as installing a dehumidifier either.
If you have water accumulation, the source of the water must be addressed. If it is a plumbing issue, fix the leak. If the problem is caused by drainage, this must be fixed as well.
If the problem relates to moisture evaporating from the ground or outdoor air coming into your vents, this can be fixed with crawlspace encapsulation.
