The Key To Mold Prevention Is Moisture Control!
The Key To Mold Prevention Is Moisture Control!
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.

Be Aware of Mold During Any Renovation Project!
Be Aware of Mold During Any Renovation Project!
In her blog, Blindsided By Mold: A True Story About A Bathroom Renovation Gone Bad—So Very, Very Bad, Trish Holder documented her battle with mold that resulted directly from a bathroom renovation project. As opposed to hiring a contractor with experience and a solid understanding of the potential risks caused by mold, she chose to hire her friend, who was a contractor.
The contractor renovated her bathroom, but did not install the shower liner and tile properly. The end result was moisture intrusion that led to a significant mold infestation that took two months and resulted in 10s of thousands of dollars worth of damage.
Trish was lucky because the contractor took full responsibility for the problem and paid for all the mold removal and reconstruction. This is a best case scenario!
But what if the contractor you hired caused the mold problem and did not pay to fix it? Then what?
The key to avoiding this type of problem is to do your due diligence when you hire a contractor. Get references, check their BBB record, find out how much experience they have, talk to other home owners who used their services, etc. Do your homework. In other words, don’t just hire the cheapest option, but the best option that can help you avoid a potential moldy nightmare!
The best option when hiring a contractor is to work with a company that has prior experience with mold testing, mold removal, and IAQ testing because they know how to prevent mold from spreading. There are many contractors, like Mold B Gone, that not only specialize in mold, but also reconstruction and renovations.
The remainder of this article will answer these three questions:
- Why could I have mold in my home?
- What should I do if I find mold during the renovation project?
- What can I do to prevent future mold problems?
Why Could I Have Mold In My Home?
According to some experts, mold is present in up to 60% of the homes in the United States.
For this reason, D.S. Berenson, an attorney with the Washington firm Johanson Berenson, stated the following:
“Mold should be treated by contractors with respect. It’s not a fire drill or a joke. The situation is no different than when a contractor encounters some other variable (asbestos, radon, lead paint) that he isn’t equipped to handle.”
The key ingredient mold needs to grow and thrive is moisture.
Unfortunately, there are ample sources of moisture in a home that could be caused by water damage from leaky pipes, a leaky roof, shower walls with cracks, foundations that allow moisture intrusion, excessive humidity of 70%, past flooding issues, etc.
People have this mis-conception that mold is only found in old homes. However, this is not true.
A disturbing trend is the fact that mold is often found in newer homes. The prevalence of mold in newer homes is directly related to the trend towards building energy efficient homes, which prevents drafts and cross-ventilation. Sealing homes tight with vapor barriers, traps moisture. The other problem is builders tend to use cheaper materials to build homes, opting for OSB, which acts like a sponge when it gets wet, contributing to mold growth.
Since mold could be in 6 out of 10 homes, if you are considering a renovation or remodeling project, then it is very important that you understand what to do if you find mold…
What Should I Do If I Find Mold During The Renovation Project?
Many Do It Yourselfers that take on home renovation projects like interior painting, kitchen remodeling, bathroom renovation, floor replacement, and window replacement, rarely understand the risks of mold. Even if they do, they may not know how to ensure that the mold contamination is prevented from spreading throughout the home.
The biggest risk you encounter by doing the renovation yourself or hiring an inexperienced contractor is cross contamination, meaning the spores spread throughout the home. You need to contain the area where you find mold to prevent this from happening. Most importantly, prevent the spores from entering your HVAC system, to prevent contamination of the duct system, spreading spores into every area of the home.
With this in mind, if you find mold during the tear down process of drywall, removal of carpet or flooring, and/or during the removal of bathroom fixtures such as the tub, shower liner, etc. your first priority is to determine the extent of the problem. If you are not sure how to do this, call a professional mold inspector.
Before you do anything, determine what the underlying moisture issue is because mold only grows when there is moisture present. Further renovations and reconstruction should only commence once the underlying cause of the moisture problem, i.e. the moisture source is identified and fixed. Failure to do this will result in future costly headaches if this step is not taken.
For mold problems under 50 square feet, like a few patches on a wall, then you can likely manage the mold problem yourself.
If you are seriously considering removing the mold yourself, contact a professional for an educated assessment and further advice on how to proceed.
It is worth getting a formal mold inspection and/or air quality test on your home before you decide to remove any mold yourself. It is better to be cautious, particularly when you are dealing with mold because exposure can cause health issues.
If you decide to remove the mold yourself make sure you keep these tips in mind:
- Prevent cross contamination by setting up a containment, using poly you can get from your local hardware store. Also, be sure to close off any vents in the area of mold removal.
- Understand that mold can be toxic, so be safe. Wear protective googles, rubber gloves, a dust mask, and protective clothing, preferably a tyvek suit.
- Don’t just spray the mold contaminated materials with bleach, praying your mold problem will go away. Bleach is not effective on porous materials, so it is best to throw out contaminated ceiling tiles, carpet, underpad, drywall, etc. Double bag and dispose of mold contaminated materials properly.
- Mold contamination on non-porous materials can be scrubbed or brushed off. You may also find some biocides and fungicides at your local hardware store or online that could be effective.
- To prevent mold spores from becoming airborne use a HEPA vacuum.
If you encounter mold, under no circumstances should you ignore it. Address your mold problem to prevent:
- Your property value from declining. Understand that as long as the conditions are present for mold growth, it will thrive and grow. Mold is like a parasite or cancer and will continue to feed on your home, causing wood to rot, and future structural integrity issues.
- Health issues. There is a growing body of research and literature pointing to the fact that mold causes health problems, like asthma and chronic sinusitis. Mold is a particular concern for mold sensitized individuals that have the genetic predisposition to Chronic Inflammatory Response Syndrome.
What Can I Do To Prevent Future Mold Problems?
To prevent future mold issues here are 10 tips:
- To prevent moisture intrusion, fix cracked foundations, damaged roofs, warped window panes and/or eroding tile grout.
- Ensure vapour barriers and insulation are in good condition and properly placed.
- If there is a moisture event such as a flood or major leak, dry the materials as soon as possible. To prevent mold growth, wet materials need to be dried or removed within 24 to 48 hours.
- Monitor humidity levels with a hygrometer. Humidity levels should be maintained between 30 percent to 50 percent.
- Reduce indoor mold spore counts with cross-ventilation by opening windows and doors to allow fresh air in.
- Properly seal windows, insulate cold water pipes and air conditioning vents to prevent condensation-related moisture issues.
- Clean and repair eaves troughs and downspouts regularly so that water flows away from the foundation of your home.
- If your home or basement has excessive humidity, use a dehumidifier, and consider water proofing your basement, particularly if it is susceptible to moisture intrusion.
- Use your senses to monitor areas of your home that are most likely to develop mold: bathrooms, kitchens, basements and attics. Visual clues likes surface discoloration and musty, earthy smells are clues that you may have mold growing in these areas.
- When cooking or showering turn on the kitchen and bathroom fans to prevent excess moisture, humidity and condensation issues. Ideally run the fans for 30 to 60 minutes.

How Do I Prevent Mold In My Basement?
How Do I Prevent Mold In My Basement?
The past three articles have focused on flood and water damage restoration.
1. Top 3 Facts About Water Damage Restoration
2. Three Steps to Reduce Flood Damage
3. What Are The Top 3 Water Damage Hazards?
The final article in this series provides you with ten tips to prevent mold in your basement. Implement these tips to avoid future headaches and costly mold removal in the future.
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.
Avoid Using Bleach For Clean Up!
As stated by Michael Pinto, CEO of Wonder Makers Environmental:
“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.
To avoid any future mold issues that could make you sick, measure the humidity levels and ensure that job was done properly by hiring a third party to perform an indoor air quality test.
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.
