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.

September 2016 marks the 8th annual Mold Awareness Month started by the National Indoor Mold Society:
“The purpose of National Indoor Toxic Mold Awareness Month is to inform, educate, and raise awareness about the adverse health effects due to exposure of indoor molds and mycotoxins.” (Executive Director, Letitia Peters)
“The reason that mycotoxins are suspected of poisoning people is based on both science and observational connections. “Mycotoxin” is the term that scientists use for a variety of chemical compounds that are produced by fungi during their growth cycle (the official term for mycotoxins is “secondary metabolites”). The suffix toxin is found at the end of the word mycotoxin because a great number of these mold-produced chemicals have been proven to be poisonous to both insects and animals—including people.”
One of the goals of Mold B Gone is to educate consumers in the Atlanta, Georgia area about mold. We believe that every month should be mold awareness month. Since launching this site, we have had nearly 37,000 views from individuals interested in learning more about mold.
There are three key lessons you need to know about mold:
There is no practical way to eliminate all molds and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
Considering that some molds, like Stachybotrys chartarum and Aspergillus, produce myctoxins that cause sickness, the purpose of this article is to list and explain the top 10 reasons you need to be aware of mold.
#1 Mold Needs Less Than 2 Days To Begin Growing!
#1 Mold Needs Less Than 2 Days To Begin Growing!
Mold requires three key ingredients to grow:
Food: wood & wood products; paper and other paper products like cardboard and wallpaper; leather; fabric and upholstery; grout; painted walls; cement; plaster (drywall); ceiling tiles; insulation materials; and carpet.
The ideal temperature of 41 degrees to 100 degrees Fahrenheit; and
Moisture, the key ingredient.
In the presence of moisture, the ideal temperature, and ample food, mold will begin growing within 24 to 48 hours. This is the reason that water damage restoration is so important during a flood event!
“Medications haven’t worked for chronic sinusitis because we didn’t know what the cause of the problem was. Fungus allergy was thought to be involved in less than ten percent of cases. Our studies indicate that, in fact, fungus is likely the cause of nearly all of these problems. And it is not an allergic reaction, but an immune reaction. This is a potential breakthrough that offers great hope for the millions of people who suffer from this problem. We can now begin to treat the cause of the problem instead of the symptoms. Finally we are on the trail of a treatment that may actually work.”
This conclusion was based on a research study of 210 patients with chronic sinusitis. The Doctors collected mucus samples from the patients’ noses and discovered fungus in 96 percent of the patients. In addition, they identified 40 different kinds of fungi, averaging out to 2.7 types per patient.
Further research was done on 101 of these patients by removing nasal polyps. What they found were eosiniphils, which are which blood cells activated by the immune system in the nasal tissue of the patients. The Doctors believe that this discovery shows that the body’s immune system is sending the eosinophils to attack the fungi which is what is causing the irritation and inflammation of the membranes of the nose. For this reason, they do not believe that traditional treatments work because they do not address the root cause of the problem, fungi, which will continue to irritate the nose membranes.
#3 Your Home Is A Buffet For Mold!
#3 Your Home Is A Buffet For Mold!
Mold is nature’s recycler, it’s main purpose in our eco-system is to break down dead organic material.
In the outdoors, the relative number of spores is small enough not to cause significant harmful health effects for most people.
However, indoors, once mold begins to grow, it will cause health concerns because the spore counts will increase. Indoor air quality is a critical concern, particularly in hot and humid climates like Georgia because residents tend to stay indoors more and use their air conditioners for heat relief.
The problem with mold is the fact that most homes are made out of the material that it loves to eat. A home is an “all you can eat buffet” for mold because homes are constructed using dead organic materials: wood & wood products; paper and other paper products like cardboard and wallpaper; leather; fabric and upholstery; grout; painted walls; cement; plaster (drywall); ceiling tiles; insulation materials; and carpet.
According to Medical News Today, asthma affects 300 million people in the world and more than 22 million Americans. Although people of all ages suffer from the disease, it most often starts in childhood, currently affecting 6 million children in the US. Asthma kills about 255,000 people worldwide every year.
Asthma is a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing. According to WebMD, no one really knows what causes asthma, but what is known is that it is a chronic inflammatory disease of the airways. Trigger and causes of asthma include allergies, tobacco smoke, environmental factors, obesity, genetics, and other factors.

#5 The Core Problem With Mold Is That It Can Grow Undetected!
#5 The Core Problem With Mold Is That It Can Grow Undetected!
Most people do not realize they have a mold problem because it is hidden.
Mold can be detected through smell, visual clues, and knowledge of the building history, ie. was there a flood or indoor leak.
One of the first signs that you have a mold problem will be a “musty” or “mildewy” odor.
The next step is to determine where the smell is coming from.
The seven areas of the home that you will likely find mold includes the following: bathrooms and kitchen that have leaks under the sink; leaks behind appliances (refrigerator, dishwater, and washing machine); ceilings and walls where there are water leaks; window sills and around the windows where condensation accumulates; your basement; closets; and crawl spaces.
#6 Modern Day Building Practices Promote Mold Growth!
#6 Modern Day Building Practices Promote Mold Growth!
The rush to make quick money and high profits by real estate developers has created a disaster waiting to happen because new homes built today are more susceptible to mold growth.
The quest to reduce energy bills means that many new homes are air tight and lack proper ventilation, conducive to mold growth.
The season that the home was built is also a factor. For instance, if the home was built during a period when there was lots of rain and the foundation was not allowed to completely dry before installing the insulation and vapor barrier, then moisture could be trapped behind the walls.
Building practices have changed. In the past, most homes were built with non-porous materials like plywood and timber which made it difficult for mold to penetrate the surface. Today, cost conscious builders use Orient Strand Board (OSB) and particle board which are porous and susceptible to mold growth.
According to the MOLDYdocumentary, at least 50 percent of homes in the United States have water damage issues caused by water line leaks, tears in moisture vapor barriers, leaky showers, condensation under eaves, and water pooling in crawl spaces. It is this water damage which causes mold to grow.
Improving building practices to prevent moisture issues is the single most effective way to prevent mold.
#7 25% of the Population Is Susceptible To Mold Illness!
#7 25% of the Population Is Susceptible To Mold Illness!
According to Dr. Richie Shoemaker, physician and expert in the field of biotoxin-related illness and author of the book Surviving Mold, 1 in 4 people have a genetic pre-disposition to the mold illness, Chronic Inflammatory Response Syndrome (CIRS):
“Genes made them prime targets for an assault by their own innate immune systems….exposure to the interior environment of a Water-Damaged Building (WDB), [causes] an innate immune response that is going haywire.”
Individuals exposed to the toxins in a water damaged building suffer from chronic illness because their bodies are trying to eliminate the foreign substances that stay in the body resulting in chronic inflammation and multiple symptoms.
It is difficult to diagnose CIRS because there are 37 symptoms patients could suffer from: fatigue; weakness; aches; muscle cramps; unusual pain; ice pick pain; headache; light sensitivity; red eyes; blurred vision; tearing; sinus problems; cough; shortness of breath; abdominal pain; diarrhea; joint pain; morning stiffness; memory issues; focus/concentration issues; word recollection issues; decreased learning of new knowledge; confusion; disorientation; skin sensitivity; mood swings; appetite swings; sweats (especially night sweats); temperature regulation or dysregulation problems; excessive thirst; increased urination; static shocks; numbness; tingling; vertigo; metallic taste; and tremors.
#8 Mold Will Reduce Your Property Value!
#8 Mold Will Reduce Your Property Value!
“Mold is a serious issue. If you leave it untreated, it continues to grow. It leads to respiratory illness and it rots the wood, leaving the property valueless.” (Ian Schlake of Respond and Rebuild)
Like a parasite or cancer, mold will continue to grow as long as there is a food source, moisture, and the right temperature.
Failing to fix the underlying causes of the mold and effectively removing the mold will lead to reduced property values caused by structural damage as the mold continues to feed on the home.
#9 Mold Remediation Can Be Costly!
#9 Mold Remediation Can Be Costly!
As mentioned in an earlier article, the cost of mold remediation will depend on three key factors:
How much of the area is infected with mold?
What kind of materials are infected?
How easy is it to access the mold?
On average, the typical household mold removal project will range from $2,000 to $6,000, but can be as high as $30,000 or more depending on the extent of contamination.
The core problem with the mold remediation industry is any contractor can offer mold removal services…so it is truly “Buyer Beware.” Because of the lack of regulation, many contractors believe they can offer mold removal services without the proper training or experience. To stay competitive, these contractors may offer “quick fix” solutions that focusing on killing the mold. However, as stated by Michael Pinto:
“Killing mold, but leaving the residue in place, is not acceptable. Since many health impacts can be triggered by exposure to both live and dead mold spores, the source and secondary contamination must be removed.” (MOLD INDOORS: Killing it is Not Enough)
Killing mold is not the answer because it is not a permanent solution to a mold problem. Professional mold removal contractors will follow an eight step process to ensure that your mold problem is fixed properly and will back up their work with a guarantee.
Don’t pinch pennies when you encounter a mold problem, the cheapest estimate may not necessarily be the best one. Do your due diligence, ask questions, get references, and most importantly avoid contractors that offer you magical solutions that involve just spraying a chemical to kill the mold dead.
#10 Mold Sickness Is A Hidden Epidemic!
#10 Mold Sickness Is A Hidden Epidemic!
According to the producers of the MOLDYdocumentary released earlier this year, most Physicians do not understand or have the knowledge to properly diagnose patients with mold sickness:
“Possibly every doctor in the United States is treating mold illness, and they just don’t realize it.” (Dr. Scott McMahon, MD)
Since most physicians are not trained to treat and identify mold illness, their patients continue to suffer in silence, mis-diagnosis, and a vicious cycle of numerous visits to different doctors and specialists that do not understand why they are sick.
Considering the statistics revealed in the MOLDYdocumentary it is not surprising that mold sickness is now considered a hidden epidemic.
At least 45 million buildings in the United Stats have unhealthy levels of mold.
You have a 33% chance of being exposed to toxic mold when you move into a new home, apartment or office. The documentary also emphasizes the fact that many foods are contaminated with mold, including corn, peanuts, and coffee.
Approximately 28 percent of the population have genes that make them highly susceptible to mold-related health issues.
Despite the fact that mold is a significant health concern, like lead and asbestos, there are no federal environmental protections laws.
Mold is a hidden epidemic because it makes people sick and they do not know that mold is the cause!
Top 5 Reasons Your Crawl Space Needs A Vapor Barrier!
Top 5 Reasons Your Crawl Space Needs A Vapor Barrier
Mold B Gone are crawl space mold removal and crawl space encapsulation professionals. We have been serving the Atlanta metropolitan area since 2009, performing 1000s of jobs.
One of the most common problems we encounter ismold in crawl spaces. The purpose of this article is two fold.
First, we will answer the most common questions asked about crawl spaces.
Second, we will explain why crawl space encapsulation is so important by listing and explaining the top 5 reasons your crawl space needs a vapor barrier.
Frequently Asked Questions About Crawl Spaces!
Frequently Asked Questions About Crawl Spaces!
If you look into your crawl space, you may notice standing water, moldy insulation, or a bad smell. Listed below are the top questions we encounter about crawl spaces.
1. Why Does My Crawl Space Get Wet?
Your crawl space could be wet for several reasons:
Cracks in the foundation or walls allow water and moisture to enter your crawl space.
Improper ventilation can allow moisture in.
Poor drainage systems also allow moisture and water in.
Poor maintenance and not sealing the dirt floor is another common reason your crawl space is wet or damp.
2. Why Should I Be Concerned About A Wet Crawl Space?
There are two key problems caused by wet or damp crawl spaces.
First, if your crawl space has standing water or is damp, this will encourage the growth of mold and mildew.
Second, the excess moisture and mold will also cause wood rot and structural deterioration.
3. Will Vents Keep My Crawl Space Dry?
No!
Unfortunately, vents will not keep your crawl space dry.
Moisture and humidity can still accumulate in your crawl space, which in turn will lead to mold and wood rot.
In addition, often times the air flow is impeded when the vents get blocked by plants or other object outside the vent. When this occurs, water that collects around the home or drips down the exterior walls can enter your crawl space creating moisture problems.
4. Can The Air In My Crawl Space Enter My Home?
Yes!
A large percentage of your home’s air, 40% or more, comes from your crawl space.
Air in your crawl space seeps up into your home through the floors, and around heating and air ducts.
The air quality of your crawl space can have a negative impact on your home if there is excess moisture and mold.
Common health issues caused by poor crawl space air include headaches, fevers, and respiratory problems.
5. What Should I Do To Keep My Crawl Space Dry?
If your crawl space is wet, the following steps must be taken.
All moisture and water must be eliminated.
Wet insulation and standing water needs to be removed.
The ventilation system must be inspected to ensure it is working efficiently. If not, it needs to be fixed.
The next step is to figure out why you have a moisture problem in the crawl space by finding and fixing any cracks, holes, leaks, or damage to the walls, ceiling, and floors.
The final step is to seal up the damaged areas and install fresh insulation, and most importantly install vapor barrier, which is explained in greater detail below.
Now that you have answers to the most common questions we encounter about crawl spaces, the remainder of this article will explain why the installation of vapor barrier is so important.
Five Reasons Your Crawl Space Needs A Vapor Barrier!
Five Reasons Your Crawl Space Needs A Vapor Barrier!
#1: Keep Moisture in the Soil!
According to the EPA, a vapor barrier will keep your home drier and is especially recommended for older homes to control dampness. In Atlanta, where humidity is a big issue, your crawl space likely has moisture and damp issues and a vapor barrier will help keep the moisture down because it will prevent moisture from escaping from the soil.
Installed correctly and spread uniformly across the soil and the the walls of your crawl space, the vapor barrier creates a barrier between moisture and your home.
#2: Prevent Ductwork from Rusting and Corroding
Most homes with crawl spaces have ductwork running underneath their home, and many have their HVAC system installed under the house as well.
It is important to keep moisture at a minimum to prevent metal from rusting and corroding.
#3: Prevent Wiring Hazards
Many crawl spaces also have wiring. Water and electricity do not mix well. Accumulation of excess moisture is a potential fire hazard and could create an unsafe environment for anyone that enters the crawl space.
#4: Keep Your Home Dry
Since excess moisture in your crawl space can enter your home through the floor boards, keeping the moisture to a minimum will also help maintain moisture levels in your home.
In addition to a damp free home, a vapor barrier will also reduce your utility bills because your air conditioner will operate more efficiently.
The risk of excess dampness and moisture in your home is mold. If your crawl space is wet and that moisture enters your home, you will not only have mold problems in the crawl space but your home.
As mentioned earlier, mold can cause health problems; moisture control is imperative in both your home and crawl space.
#5: Keep Your Crawl Space Clean
Your crawl space is an area of your home that you can potentially use for storage. In order to ensure that your crawl space is a safe and clean environment, a vapor barrier will reduce moisture and also keep the area clean and less inhabitable for rodents and insects.
If you plan to use your crawl space for other uses, such as storage, we recommend that you use a stronger and thicker barrier.
The most important role that a vapor barrier plays is keeping the moisture in the soil. At the same time, it will help maintain a cleaner and safer environment for you, should you choose to use it for storage or other uses.

If you have not visited your crawl space, take a look. Typically, you will find the following:
Dirt. Most homeowners have a bare dirt or rock crawl space.
Ductwork. Many of your home appliances run out through the crawl space area. Washers, dryers, and plumbing pipes are often found running along the ceiling of the crawl space, to be vented or piped to the outdoors or external holding tanks. Ductwork for the home heating and cooling systems are also usually found here.
Plumbing Pipes. Home plumbing is usually found in your crawl space, funneled outside to your septic tank or the sewer system. These pipes are usually heavy duty so most homeowners are unconcerned about their safety. However, these pipes still require maintenance and care. Changes in temperature during the warmest and coldest months as water flows through them can cause condensation. Condensation and the increase of moisture in the air leads to mold growth.
Electrical Wiring. Along the ceiling and walls of the crawl space you will usually see electrical wiring. Keeping these safe from the gnawing teeth of crawl space vermin is important.
Vents. You will also notice various vents along the bottom walls of your house. These vents allow for air movement and ventilation for your crawl space.
Insulation. Insulation is important. If you see nothing but bare beams and dirt, this is a concern. Up to 40% of your air comes up from the crawl space. You can lose up to 45% of your home’s heating and cooling energy through non-insulated crawl spaces. In addition, non-insulated crawl spaces are will incur mold growth and attract insects, rodents, and other crawl space vermin.
Vapor Barrier. Vapor barriers help maintain the health of your crawl space and your family. Crawl spaces protected from excess moisture are less likely to develop mold or allow vermin and insects into your home. Vapor barriers protect not only your crawl space, but your entire home.
Beams. Beams, heavy wooden or metal support structures, keep your home structurally sound. These beams run vertically and horizontally through your crawl space structure.
Drains/Pumps. You may also notice a drain in the floor of your crawl space. Usually this is a sump pump, a water pump designed to carry any excess water away from the house in the case of a flood. Drains allow excess water to drain away a safe distance from the house, usually 6 feet or more.
Critters and Other Creepy Crawlers. It’s all too common that a homeowner pokes his head into his crawl space to discover a happy population of insects, mice, rats, squirrels, or even snakes! Getting these invaders out of your home can be challenging. To be safe, call a pest control company.
Four Clues That You Have Issues With Your Crawl Space!
While you are taking a look at your crawl space, give Mold B Gone a call if you find any of these problems:
Standing Water or Water Damage: Water damage can weaken the foundations and walls of your home, and needs to be dealt with quickly.
Mold. Mold can be hazardous. If you have large areas of mold spreading across your beams, in your insulation, or along the ground it needs to be removed. Left unchecked, mold can severely damage your home and your air quality.
Ruined Insulation: No insulation lasts forever, though some types of insulation are more long lasting than others. When insulation is falling to pieces or has rodents nesting in it, it’s time to remove the old insulation and replace it.
High Humidity: Knowing your crawl space humidity is essential to keeping it clean and safe. Vapor barriers are an important part of a crawl space because it prevents moisture and high humidity, something that creates a breeding ground for mold and pests. If you have a bare dirt floor, crawl space encapsulation is important.
Now that you understand what is in your crawl space and the top four signs that you may have issues with your crawl space, the remainder of this article will list the top 5 ways your crawl space affects your home.
#1 Poor Air Quality
Moisture accumulates in your crawl space because of high humidity, changing temperatures that leads to condensation, rainy weather, and the lack of preemptive solutions, like a vapor barrier. For this reason, it is important that the moisture content of your crawl space is monitored properly.
If the moisture content of your crawl space is not monitored, mold and rot will grow in the insulation or on the wooden beams. When the mold grows, it releases mycotoxins that can seep through the floorboards of your home, which in turn can cause sickness.
Even though the mold is growing under your home, you need to take action because 40% of the air in your home seeps up through the crawl space.
Simply put, if your crawl space has mold problems, then the indoor air quality of your home will be negatively affected.
#2 High Energy Bills
Properly insulating your crawl space will save on utility costs because the insulation prevents temperature transfers. This will ensure that your home stays cool when the air conditioner is running and warm if you need to heat your home during the colder months.
#3 Rodents and Insects
Despite the fact that your crawl space may be surrounded by a thick layer of concrete serving as the foundation, your crawl space may not be as predator-proof.
There are two key reasons that rodents and insects can affect your home.
First, droppings and feces left behind will affect the air quality inside your home.
Second, certain rodents, like squirrels will get curious and start chewing on any exposed electrical wires, ruin insulation, or rip holes in a vapor barrier.
#4 Damaged Subfloor
Moisture accumulation in your crawl space will not only affect the air quality of your home, it can also seep through the ceiling of the crawl space and damage your sub-floor. When this occurs, it will begin to warp and eventually need to repaired or replaced.
#5 Compromised Foundation
More than just the subfloor, however, moisture problems can also cause issues for the foundational level of your home. The wooden beams that hold up your home’s structure can be damaged by consistent exposure to high levels of moisture, condensation, or humidity. In some not-so-uncommon cases, crawl spaces have actually flooded, causing significant structural damage that resulted in thousands of dollars of repair work.

Top 3 Questions About Crawl Space Humidity
What’s the threshold humidity level for mold growth?
When the relative humidity of your crawl space is 70% or higher, mold can thrive.
“Relative” humidity is the humidity level expressed in a percentage of the amount of moisture in the air needed for “saturation” (i.e. the highest level of humidity – 100%).
The amount of water the air can hold (humidity level) is dependent upon the temperature of the air itself.
When the humidity level begins to creep up past 70% relative humidity, this provides the perfect environment for mold growth!
I’m seeing condensation. What does that mean?
Condensation is an indication that the air within your crawl space has reached 100%.
The air can no longer hold the moisture and it’s condensing onto the surfaces, causing the organic materials that make up your crawl space to become damp, which will result in mold growth.
How do I know when the humidity in my crawl space is at a dangerous level?
A hygrometer is a device used to measure the humidity of indoor air.
Using this tool to measure the humidity of your crawl space is a great way to monitor the amount of moisture present.
A thermo-hygrometer measures both temperature and humidity level.
These devices are even more ideal for crawl space atmosphere monitoring because the relative humidity level is contingent upon the moisture in the air in relation to the air’s temperature.
Being able to track the changes in both of these conditions in your crawl space will allow you to see trends and anticipate necessary changes.
For instance, if the weather is hot during the day but the temperature plummets at night, this can cause problems for your crawl space’s humidity levels.
The daytime temperature is higher, which allows the air to hold more moisture.
As night approaches and the air cools, the amount of moisture the air can hold also decreases – causing the relative humidity level to rise.
A crawl space that was at a permissible humidity level during the day can run into problems when night falls.
Being able to see these changes on your thermo-hygrometer can help you identify these types of trends so that you can respond appropriately.
Keep in mind that properly insulating your crawl space and installing vapor barriers will help regulate the temperature and keep moisture levels down, resulting in less fluctuations in the air’s relative humidity.
Humidity Levels In Your Crawlspace Affect The Rest Of Your Home
Having unconditioned air below your living spaces makes the whole house harder to heat and cool as well as provide the perfect damp setting for mold spores to breed.
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. So if you have a crawlspace, what solution is available?
