With heavy rainfall comes a tremendous amount of moisture. Leaks and condensation increase, temperatures and warm drying daylight decrease.
These are optimal conditions for mold growth, both interior and exterior. As exterior mold spores explode in number some of them are bound to settle in our indoor environments. Here’s an overview from the EPA on Mold growth in the home.
So what can you do to reduce to likelihood mold will take hold?
I have some tips to minimize the conditions conducive to mold growth and maximize you and your family’s health.
Mold needs 3 conditions for optimal growth:
The Right temperature. Some mold species can grow at low (below 50 degrees F) and other species at high (above 90 degrees F), but most common mold species that grow indoors grow ideally at 55-85 degrees F. Unfortunately this is the optimal temperature for human comfort. So it is unlikely you can keep your home at a temperature that is inhospitable for mold growth. So we will not concentrate on that.
An organic food source. Different species of mold like to eat different things, but they all need something organic to munch on. Many mold species love cellulose, i.e. wood and paper. These are the natural composters and when it rains these species start to eat up all the fallen branches and leaves in the forest, as well as our yards emitting millions of spores that make their way into our homes. Inside our homes molds like to eat wood. This is what “dry rot” is, fungi usually consisting of 2 species, Ascospores and Basidiospores. Other species like to eat paper, such as cardboard boxes, books, and paper backed wallboard, such as sheetrock. Pennicillium/Aspergillus and Stachybotrys (colloquially known as toxic black mold) are often found on wet or moist paper. Cladosporium, the species most often found growing on windowsills and in bathrooms, can eat a variety of Biofilms (household dust consisting of epithelial cells (dead skin cells) insect parts, pet dander, natural fibers such as cotton and linen, etc.). Some mold food sources we cannot easily remove from our home such as framing lumber and wallboard, but others we can, such as cardboard boxes.
This is the big one and the one I will be giving tips on below. Mold needs moisture. There is a common saying in our business: “Mold is the symptom, moisture is the problem”. Mold growth either needs liquid water or high humidity. Liquid water can come from condensation on windowsills and in bathrooms, or from leaks, either internal or external. Without liquid water mold will not become active unless the humidity is high, usually 60-80% RH depending on the species. When the humidity is high enough, mold can become active and grow by absorbing moisture directly from the air.
Here are some tips to reduce both food sources and moisture in your home and thus reduce the likelihood and amount of mold that may grow inside your home:
Let’s start outside. When it rains water can easily enter what we call the “Building Envelope”. It is very important to make sure your site drainage system is clear from debris and working properly to move rain water away from your home, foundation, and crawlspace.
Clean the roof of any leave or other debris.
Make sure downspouts are in good repair, not clogged, and properly attached any extensions or the site drainage system.
Make sure all property drains are clear of debris and flowing freely.
Check the “Building Envelope” for possible sites of water intrusion, i.e. leaks.
Window and doorframes are spots where water can intrude. Check all door and window frame caulking for cracks and gaps and repair where necessary.
Inspect the sealant around roof penetrations. Repair where necessary.
Check building siding for cracks, peeling paint, holes, etc. Anywhere water may be able to get in.
After a heavy rain walk around the entire house and look for standing water, and clogged drains. Look inside the crawlspace and make sure there is no hidden flooding. Carefully check the inside of the house, take a close look at the ceilings, around windows and doors, and walls for small leaks. Because all big leaks start out as small leaks! Check under sinks and around tubs and toilets to make sure there are no plumbing leaks adding moisture to the interior of your home.
Assuming there are no leaks and your drainage system is working well, what other sources of moisture can address?
Inside a home the occupants can produce a tremendous amount of moisture. On average each human occupant expires (breathes) and perspires (sweats) about 2 POUNDS of water into the air a day. Pets can also add to this moisture source. During the winter we often close out windows, as it is cold out, and most residential heating systems have no way of bringing in fresh air or ventilating out moist, stale interior air. Thus interior humidity can often increase to levels above 60%, which is ideal for mold growth.
So what can we do about Mold Growth?
Monitor interior humidity. Small, portable humidity monitors are available for around $10-15 and can be placed around the home. If RH (relative humidity) is consistently above 65%, action should be taken. Ideally, interior RH should be between 45-55% RH. Below 40% RH mucous membranes start to dry out and can cause occupant discomfort.
Open windows when practicable to help flush out moisture and other interior contaminants. Even 1 hour a day can make a big difference, although 3-4 hours is recommended.
Run ventilation fans in bathrooms and kitchens to help exhaust excess humidity from cooking and bathing. Run fans in bathrooms for at least 20 minutes after bathing. Timer switches can be installed on most bathroom exhaust fans and are highly recommended.
Wipe excess condensation from windowsills. Inspect windowsills often. Do not keep curtains closed as this can trap moist, cool air and promote excessive condensation.
The above tips can help reduce moisture sources, what can do we do about reducing mold food sources?
Do not keep books, papers, or cardboard boxes in moist areas such as attics, garages, basements or crawlspaces. Attic and crawlspaces should not be used as storage areas, but if you must store items in a garage or basement, we recommend sealed plastic bins.
Keep areas mold likes to grow clean and dry. This means cleaning dust (biofilms) from windowsills, baseboards, and doorframes. Vacuum carpet regularly with a HEPA vacuum. The recommendation is to vacuum and sweep one day per week PER OCCUPANT, including pets!
Check behind drapes and furniture for hidden condensation and biofilms. Allow airflow to reach these areas by opening drapes often and moving furniture a few inches from walls, especially exterior walls that can become colder and promote condensation.
Also, trust your nose, that musty smell is a sure indication of active mold growth. That musty smell is caused by microbial VOC’s, airborne chemicals that are a metabolic by-product of mold digestion.
If you think you have a hidden source of mold, call a professional Certified Microbial Investigator for a full mold inspection. Excessive interior mold can cause structural damage to your home and its contents, as well as allergic and respiratory reactions in some occupants. Take heed and be diligent, and you can survive this hopefully wet winter relatively mold-free.
At the end of the day, after work or school, we always look forward to coming home again. Our minds and hearts are attached to our homes because of the sense of belonging, comfort, and safety that it provides. Feeling safe is the state of not being exposed to danger or risk, and that is how our homes should feel, right? So, let me ask you, are you sure you are safe within your home?
You may feel that there’s nothing lurking within the corners of the rooms of your home. However, if you are setting aside the fact that there could be molds in your house, then you are getting further away from the sense of safety that your home should provide. Molds are not something you should overlook.
Molds usually appear on damp building materials and may look like stains. They can come in various colors and sizes. You may have seen some sort of spot growing in the interior of your house, and that is not something that should be ignored.
Molds can create a lot of nuisance and danger for you and your loved ones. It can give your family nasal and sinus congestion, coughs, headaches, asthma, skin irritations, and much more.
If your home is attacked by molds, you have to do something about it. Here are some signs that your house may have been infected by molds:
Allergic reactions. If you notice that your allergies tend to react and even get worse while you’re at home, chances are there are molds growing in your house. Some allergic reactions to mold could be sore eyes, sneezing, and nasal congestion.
Mold odors. A musty or moldy smell can be a great indicator that there are molds in your home. If you can smell mold, then you probably have mold. You should thoroughly inspect your home before it gets worse.
Visible signs of molds. When you see greenish black spots of molds, then it’s obvious. Take action immediately.
Water issues. If you have experienced water leakages, condensation, or past floods in your house, mold growth is likely to have occurred. If there are water stains or discoloration of the walls due to a moisture problem, there is most likely mold growing behind the material.
Your home is where your family should feel safe. If you’ve noticed the above-mentioned signs of mold growth in your house, please do not ignore it. Ignoring it might cause you bigger problems in the future.

House fires are terrifying because the flames can cause intense bodily harm that results in serious injury and even death. Once the fire is put out, many homeowners are relieved in the sense that the threat to their life or health has ended. However, the flames themselves are not the only potential source of health issues. Many of the byproducts of a fire are toxic. Fires leave behind smoke, soot, corrosive byproducts, and even mold that negatively affects your health. It is important to know the health risks caused by the byproducts of a fire to keep yourself and your family safe in the aftermath.
All fires involve smoke and everyone knows that smoke inhalation is extremely dangerous because of the chemicals it contains. Smoke is the byproduct of incomplete combustion and contains the following toxins:
Carbon Monoxide (CO) and Hydrogen Cyanide (HCN): The potential health effects of carbon monoxide are well known as many homes have carbon monoxide detectors for safety. Less people know about the risks of the other major chemical in smoke, hydrogen cyanide. Hydrogen cyanide is over 30 times more toxic than carbon monoxide and inhaling a combination of both can be deadly. Smoke inhalation is the leading cause of fire related deaths.
Chemicals from Burnt Materials: When materials such as wood, drywall, and flooring are burned in a fire, they release hundreds of chemicals in the smoke that are harmful to your health. Some of the dangerous chemicals released by burning household materials include hydrogen sulfide, hydrogen chloride, carboxylic acids, nitrogen oxides, acid gases, sulfur dioxide, and much more.
After the fire and smoke have cleared, there is still a substance present that can spread throughout the home and cause health issues as well as property damage; soot. Soot is dangerous because it spreads and settles everywhere including the air ducts where it can get redistributed into the air. Most health problems caused by soot result from inhalation but soot can also get absorbed in the skin and eyes. The main health effects from soot include lung irritation and respiratory issues such as bronchitis and asthma as well as more serious issues including heart attack, stroke, and even cancer.
Few people associate mold growth with house fires but if a house fire is extinguished with water, this excess moisture can quickly lead to mold growth. Moisture is the main cause of mold growth and organic materials that are wet from putting out the fire can become contaminated with mold within 48 hours. Mold not only adds to the health risks already present after a fire, but also causes even more property damage that makes the restoration process longer and more expensive.
If a fire breaks out in your home, make sure that everyone evacuates safely and do not return to your home until it has been restored and deemed safe. The byproducts of a fire are just as dangerous as the fire itself and can cause serious health effects long after the fire has been put out. It is of extreme importance to begin the fire damage restoration as soon as possible by hiring professionals that can safely remove dangerous byproducts from soot and smoke. These professionals have effective cleaning products and personal protective equipment to keep themselves safe during the restoration process

Molds are everywhere. It may not be seen by your naked eyes but you are will not be so sure about their existence. Mold is a kind of fungi that grows from different spots. All of us are exposed from variety of molds that can affect our health.
How sure you are that your homes are free from any threats of molds? Let us now talk about how mold gets inside your homes and other premises.
Our idea about mold is that it grows naturally outdoors. Looking at the positive part, mold is a fungus that serves as earth’s most important recyclers. The only problem is that when a mold combined with water damage and exposed to prolonged humidity and dampness, that is the moment where mold now become a threat to one’s life.
Here are some of those common sources of indoor moisture that can lead to mold problems,
Leak and damage roofs
Poor management of rainwater drainage
Process of condensation
When you observed the above mention scenario inside your homes and within your vicinity, then you need to make some immediate actions to solve the problems.
How to prevent molds growth?
Prevention is always better than any cure. It is better to do something early than suffering consequences. One way to prevent mold growth is to control excessive moisture and condensation. Since molds grow critically because of the presence of water damage and excessive moisture then you need to be at those points in the first place.
What are the top three factors that contribute in condensation of water resulting to mold?
Poor Ventilation. If your place has a little access on air, there is a greater chance of an increased in condensation and mold growth. There are spots in our homes when there is a little supply of air the reason why that even though we keep on cleaning our place, molds existence is still there.
Temperature Changes. More warm air means more moisture generated. If we will not be mindful about the temperature of our home, there will be a great chance of mold formation
Relative Humidity. When air is saturated, condensation occurs resulting to situation where it can no longer hold any moisture. When there is condensation, then mold is the counterpart. In order to maintain humidity levels, used of dehumidifiers is advised.

How to reduce mold spores and allergens in your home . .
Learn How To Get Rid Of Mold Spores In Your Home And Decrease Allergies
At Fun Guy Inspections, we believe in taking the proactive approach when it comes to keeping your home safe from common dust mites, allergens, and mold spores that take place as a result of water damage. Safeguarding your home from these particles and spores is a very important responsibility for those that suffer with increased allergies, or asthma. Those who do not take indoor air quality seriously are placing themselves and their loved ones at risk. reduce mold spores
Using a Hypoallergenic Vacuum
Part of reducing mold spores and allergens from your carpeting is not an easy task and not one that can typically be done by hand. Your furniture fabric is also highly susceptible to the presence of particles, allergens, dust mites, and mold spores. Fortunately, a HEPA vacuum (also known as a hypoallergenic vacuum) can serve as the perfect solution.
Using an Hypoallergenic Air Filter
In addition to vacuuming, a homeowner can also install a hypoallergenic air filter to reduce the amount of pollutants that freely circulate through the air. HEPA air filters (which means high efficiency particulate arrest) forces the air supply in your home through a fine mesh filter that is designed to trap all of the harmful allergens that typically float around unabated.
Consider a Mold Inspection
If neither of the aforementioned methods work as hoped, it is time to contact the good people at www.funguyinspections.com for more information. In all likelihood, you will be in need of a mold inspection, as well as an air quality test. We can determine if you need to reduce the mold spores and allergens in your home after testing. reduce mold spores
When it comes time to conduct the mold and allergen testing, this process is completed when you allow our experts to take samples of the air inside your home. In order to make an accurate reading, we also take a sample of the air outside, in order to compare them on a side by side basis.
Certified mold inspectors can then let you know what their determinations are and whether your home and its occupants are at risk. If the levels are higher than recommended, you and your family may be at risk of mold exposure.
