How to troubleshoot mold on interior walls

Last Updated on December 4, 2019 by Diana Rodriguez-Zaba

When you spot it taking hold behind the toilet or under the sink, you have a clear line of attack. You solve the problem with bleach, water and a good scrubbing. Still, you worry about the stuff invading sheetrock and crawl spaces. This isn’t something that you can ignore.

How do you deal with a hidden threat like mold inside the walls?

We often hear this question from concerned residents who contact us about mold inspection in their Chicago homes. It’s important to understand mold basics before you decide on how to handle unhealthy growth that you can’t see.

Follow Your Senses

If you can smell it, it’s there behind the walls. That unmistakable musty odor that makes your nose curl is a sure sign that you’re dealing with a growing mold problem. Do your sinuses stop up when you spend time in one room? Do your eyes start itching? Those physical symptoms are often reactions to hidden mold growth.

Keeping a clean house should be enough, but mold thrives in all kinds of areas throughout your home. A plumbing leak or flooding accident leaves moisture in dark crawl spaces and creates a perfect breeding ground for mold. By the time you see it speckling a wall, you have a serious problem on your hands.

Recognize the Danger

Mold that grows in and through permeable sheetrock feeds on its cellulose material. This natural process results in contamination that you can’t always see. A bad outbreak can become visible on the outside of a wall, but you can’t know the size of the problem without using special detection equipment or pulling down the sheetrock.

This kind of mold cleanup poses serious health hazards. Airborne mycotoxins irritate allergies and compromise weakened respiratory and immune systems. Teardown and disposal of contaminated materials spreads the microscopic compounds, so it’s very important to always wear protective gear when you take on this kind of project.

The DIY Mold Testing Process

While home mold testing kits are simple to use, they only capture samples in the air and on exposed surfaces. They aren’t intended to detect mold inside walls, but they can provide a starting point for DIY mold removal.

A top-of-the-line home mold testing kit should include:

• Growth medium that serves as a base for tested samples
• Petri dish for passively catching airborne spores
• Sterilized swabs to collect visible samples directly from surfaces
• Sample bags for shipping suspected mold to testing labs

Once you send off your sample, turnaround time can vary from five business days to three weeks. Also, be aware that the cost for mail-in analysis is usually in addition to your original mold kit purchase price.

If You Tackle It by Yourself

We outlined your options for DIY mold removal in an earlier post, but be prepared to tear out sheetrock in order to reach mold inside walls. The job gets messy and heavy, so it’s a good idea to enlist some help. If you tackle a mold project by yourself, protect your health by always following these important guidelines:

• Never try to clean more than 3 square feet.
• Always wear recommended safety gear.
• Be very careful with mold that permeates affected surfaces.
• Never attempt mold removal if you or anyone in the house suffers from respiratory problems.

Calling in a Restoration Professional

If your home testing kit samples return with positive results for toxic black mold, we highly recommend that you let professionals take care of it. You can remove this dangerous mold by yourself, but the job becomes much more hazardous when you have to rip out contaminated sheetrock.

DIY mold removal from inside walls can quickly become a project that’s just too big for most homeowners. If you have any doubts before you get started, consider the advantages of calling in a professional restoration contractor:

• Highly trained technicians use state-of-the-art equipment to precisely locate mold growth.
• Testing is done quickly, and certified results are returned as soon as possible.
• Team work speeds up removal and remediation processes.
• All sources of moisture that caused the mold outbreak are identified and repaired.
• Expert crews take care of all reconstruction and restore your home to its original condition.

Working with restoration professionals streamlines the job, eliminates sources of future mold outbreaks and leaves you with peace of mind and a healthier home.

How to troubleshoot mold on interior walls

If you live in or around Grand Rapids, it is important to find out how to solve mold problems in Grand Rapids before they become worse. It is especially important to know how to prevent mold problems in Grand Rapids, since this may indicate how to avoid future problems, too. There are many ways how to solve mold problems in Grand Rapids , but not all of them will be effective. It is, therefore, necessary to do your homework on the subject, which can save you money and time, both of which can be important in this tough economy.

While it may be tempting to attempt to solve the problem on your own, say using bleach (not recommended), remember that mold may also get its way into and beneath wallpaper borders and even around and between walls and windows, which can prove to be quite a costly mistake.

Properly Ventilated Area:

One of the ways how to solve mold growth in Grand Rapids is to have the area properly ventilated. Mold needs moisture and light to survive, so if you find mold growing within walls or on the ceiling, it means that the moisture levels within are lacking, and mold is waiting to grow.

In the basement, this can mean that there is not enough fresh air ventilation to help encourage the growth of mold. This can result in a serious problem as mold develops and begins to eat away at the wood framing of the house, creating a foul and musty odor that must be smelled to avoid attracting more mold.

Sealed House from Outside:

The best way how to solve mold in Grand Rapids is to ensure that you have properly sealed your house from the outside. For the interior, you can seal the windows, especially if they have honeycombed frames. If you must use external seals, make sure that they are treated with an anti-microbial solution to kill any potential mold spores that might be present. You should also have your ductwork and sump pumps sealed and cleaned regularly to prevent excess moisture and dampness from building up within the house.


When it comes to the exterior of the home, you will want to apply a solution that does not contain bleach to kill all the mold spores. This solution should be a rate-based solution that is non-toxic. You can purchase rate based solutions at your local hardware store. However, if you do not wish to purchase a borate-based solution, you can pour a cup of bleach onto a sponge and scrub away, or you can purchase a borate-based stain from your local hardware store. Once the stain has dried, you can apply a solution of bleach and water on the areas that remain and allow the bleach to soak into the wood for a few days to help prevent mold spores from developing.

Hire Professional Company:

If the mildew or mold growth behind your home does not go away on its own, you may need to hire a professional mold removal company. This is because mildew can spread very quickly. If you do not want to hire a professional, you can search the internet to find some do it yourself kits that can be used to get rid of mold. These kits are widely available, however, they are not always successful. They often contain chemicals that can be harmful to your health.

High-Powered Equipment:

If you have hired a professional mold removal company, they will use high-powered equipment to get at the fungus. The fungus will be extracted using extreme heat. Once this fungus has been extracted, you will be able to determine if you need to repair the mildew or the fungus. If you do not repair the mildew or the fungus, it will continue to cause problems for your family. You may also have to replace the carpet in your home because mold damage is so severe that the carpet will start to wear down and break down.

Safely remove unsightly and potentially hazardous mold from the bathroom and other moisture-prone zones—and keep it at bay—with these easy methods.

How to troubleshoot mold on interior walls

Q: Ugh! I’ve recently discovered ugly patches of mold on the walls in my bathroom. Is it dangerous? How do I get rid of it?

A: It’s an all-too-common problem in any area of the home where moisture levels tend to be high: splotches of mold growing on the walls or ceiling. While mold can sprout anywhere along a wall, it’s most often found either up high near the ceiling, down low near the floor, or creeping along edges of trim or baseboards. This frustrating and potentially hazardous problem is most common in bathrooms with frequently used showers or tubs, but can also affect damp basements, kitchens, or laundry rooms. If conditions are damp, ventilation is poor, and temperatures are high, airborne, invisible mold spores—found virtually everywhere—happily settle in and grow.

The most feared type of mold is Stachybotrys chartarum, typically referred to as black mold, which can cause chronic respiratory irritation, headaches, and persistent fatigue. According to the Centers for Disease Control and Prevention, black mold requires constant moisture for growth—not just intermittent moisture from the shower—so it’s likelier that your problem is caused by another less toxic variety of mold. That said, a severe mold situation can lead to or exacerbate respiratory or immune system issues.

If mold is growing in an area that remains wet, it’s best to consult with an expert in mold remediation for professional cleaning services. The good news is that you should be able to clear up most everyday mold problems yourself. Keep reading to learn techniques for curing the common mold.

How to troubleshoot mold on interior walls

Remove mold stains from walls.

Mix a solution of one part bleach to three parts water in a spray bottle, and thoroughly saturate the moldy areas of the wall. Open a window and/or keep a fan running as you work; bleach fumes are unpleasant and can be irritating to the lungs. Let the bleach soak into the mold on the walls for several minutes, then use a scrub brush to remove the stains. If the stains are extensive or deep, you may need to repeat the process to remove all discoloration.

Kill mold on walls.

While bleach works well to kill surface fungus and remove the ugly marks on the walls caused by mold, it doesn’t penetrate deeply into the drywall and so it leaves the mold’s “roots” undisturbed. That means the problem is likely to reoccur, sometimes within days. To kill mold beneath the surface, simply spray undiluted white vinegar onto the affected area and let it dry. Don’t worry about the odor; the smell will dissipate once the vinegar is completely dry.

How to troubleshoot mold on interior walls

Prevent future mold growth.

Once you’ve removed all mold on the walls, keep those surfaces looking good with a few preventative measures:

  • Wipe up puddles or spills immediately.
  • After a shower or bath, leave the bathroom door open with the ventilation fan running—or the bathroom window open—for at least 20 minutes to allow humidity to diminish.
  • Keep an eye out for plumbing leaks. Fix them right away—most types of mold only need around 24 to 48 hours of moisture before spores start to multiply, and black mold becomes more of a possibility the longer water leaks are left untended.
  • Spread out damp towels so they dry quickly.
  • If possible, shower with the bathroom door open so condensation doesn’t build up in the enclosed space.
  • Set a canister of moisture-absorbing desiccant—these generally contain either silica gel or salt—in a corner of your bathroom, or run a dehumidifier if you live in a particularly humid climate.
  • Squeegee shower walls and glass doors after every use to help remove the moisture that encourages the growth of mold on your walls and also prevent unsightly hard-water and soap-scum buildup.
  • Use mold-resistant paint in the bathroom or mold-prone areas when it’s time to repaint or remodel.
  • Clean the bathroom weekly with your favorite disinfecting product, whether that be bleach, vinegar, or a commercial cleaner, and remember to scrub underneath bottles of shampoo and other shower necessities where mold spores tend to linger.

Mold in walls is a particularly tricky problem. It can grow there for quite some time before you even realize it’s there, spreading unseen inside the walls. The mold in your walls may not stay in the walls, either. It can spread throughout your home. And even if you’re not aware of its presence, mold inside walls can cause health problems.

How Do You Know if There is Mold in Walls?

If you’ve had significant water damage, like a broken pipe inside a wall or flooding in your home, there is a possibility of mold growing within the walls. In such cases, you’re going to need to remove and replace the drywall anyway, so while you’re at it, it’s easy enough to check for mold inside the walls.

If you see mold on the surface of a wall, it is possible there is mold inside the walls, as well. Because it is difficult or impossible to remove mold from porous materials like drywall, you will need to remove and replace the moldy section of drywall. That will make it easy to check for mold inside the wall. Use a small mirror with a long handle and a flashlight to look inside the walls for mold.

Yet another sign of mold growing unseen inside the walls is a musty odor. There are other, easier places to search for hidden mold if you smell that characteristic musty odor that indicates mold is present somewhere, but if you’ve looked elsewhere and can’t find it, you may need to check inside the walls.

If you’re not sure whether or not you need to check inside the walls, you can consult with a mold removal professional for advice.

How Do You Check for Mold inside Your Walls?

To check inside your walls for mold, you’ll need to carefully cut out six-inch squares of drywall, remove the cut-out squares, and use a long-handled mirror and flashlight to look inside for mold. It is recommended that you check in several places, since you might miss small amounts of mold if you only look inside the wall in one spot. The U.S. Environmental Protection Agency (EPA) recommends hiring a professional to help you look for hidden mold, including mold in walls, since the process can potentially spread mold throughout the room and expose you to harmful mold spores, if in fact it turns out there is mold inside the wall.

How Do You Remove Mold Inside Walls?

Before attempting to remove mold in walls remember that these procedures are to be performed inside a contained area while wearing personal protective equipment and operating negative air filtration equipment.

If mold is growing on the back of drywall, the drywall must be removed and replaced. Any insulation in the wall should be removed and replaced. Moldy materials should be double bagged in heavy plastic trash bags before you carry them through the house for disposal, to prevent the inadvertent spread of mold throughout the home in the process.

After sheetrock walls and/or ceilings are removed, the exposed studs and joists and the surfaces between the studs and joists need to be HEPA vacuumed to remove all of the settled dust deposits from these surfaces, as these deposits are likely to contain elevated levels of mold and bacteria. The same holds true for floor joists when wood floors are removed during a mold remediation project.

After the HEPA vacuuming work is performed, studs, joist, and surfaces in between need to be disinfected. Any cleaning product that contains an anti-microbial substance is adequate to disinfect these surfaces. Foster 40-80 is an excellent product, which we recommend. Metal studs and sills can be wiped with a cloth or paper towels dampened with the product. For large areas, you can use a one-gallon garden-type pump sprayer containing the disinfectant and spray the surfaces. Masonry surfaces, such as concrete, bricks, tiles, cinder blocks, etc, and wood and vinyl floors are also disinfected with disinfectants when masonry materials are associated with a mold remediation project or are located inside a contained work area.

After surfaces are disinfected and dry, any wood surfaces displaying residual mold should be encapsulated with an encapsulant coating. Encapsulant coatings are similar to paints, but they contain chemicals that have fungicidal properties, which kill mold. Additionally, when the encapsulant paint dries, the coating hardens and locks down any mold onto the surface of the wood so that mold spores cannot become airborne. Remember, dead or alive, mold is equally allergenic, so it is important to encapsulate any residual mold. Encapsulant coatings are used on wood, provided that the wood is not wet. Otherwise, you have to wait until the wood is dry before using the coating. The encapsulants can be applied to wood surfaces using a brush or a roller. For large areas of wood containing residual mold, high-pressure airless sprayers are used, but these sprayers are expensive to purchase. A popular and effective encapsulant is Caliwel paint, which contains calcium hydroxide, a chemical that gives the paint anti-fungal (fungicidal) properties. Surfaces to be encapsulated must first be primed with Caliwel primer before being encapsulated. Another common encapsulant is Foster 40-50, which is white, and Foster 40-51, which is clear. Both the Caliwel product and the Foster products can be applied with a brush, roller, or high- pressure, airless sprayer.

Mold belongs to the fungus family, along with mushrooms and yeasts. However, the characteristic that differentiates it is that it does not belong to the vegetable or animal kingdom, due to the cells that form it.

There are believed to be hundreds of species throughout the world, although the most common within the home are Cladosporium, Penicillium, Alternaria, and Aspergillus. These tend to form in areas where it is against moisture, in spaces such as walls, tiles or the bathroom.

The downside is that, beyond causing terrible stains, its presence is related to respiratory problems and allergic reactions in thousands of people.

Remedies to combat mold

Fortunately, there are a number of home tricks that allow us to remove mold quickly and effectively without having to use harsh chemicals. Would you like to meet them? In that case, keep reading everything that we are going to tell you about. Let’s get on with it!

1. White vinegar

White vinegar is a product widely used in household cleaning, since it helps to easily remove grease and dirt accumulations. It also helps to make smooth surfaces shiny (mirrors, glass, ceramics, etc.). On the other hand, it is attributed antibacterial and antifungal properties.

How to use?

  • Pour a cup of the product into a spray bottle and spray it on the stained walls.
  • Let it act for a few minutes and clean with a cloth.
  • Repeat this process as many times as necessary to remove all of the mold.

2. Tea tree essential oil

Tea tree essential oil (or melaleuca oil) is a product that has a much more pleasant aroma than white vinegar and is also credited with antifungal and antibacterial properties.

How to use?

  • Dilute a teaspoon of tea tree essential oil in half a liter of water and spray it on stained surfaces.
  • Wait a few minutes for its compounds to act and rub it with a cloth or brush.

3. Hydrogen peroxide

Although we limit its use to the disinfection of wounds, hydrogen peroxide has whitening and antibacterial properties that serve us for various cleaning tasks at home.

In this case we will use it undiluted to make the process of eliminating the mold accumulated on the walls easier.

How to use?

  • Spray hydrogen peroxide on the affected walls, let it act for 15 minutes and rub with a brush.
  • Rinse and repeat your application if you consider it necessary.

4. Sodium percarbonate

Sodium percarbonate (also known as solid hydrogen peroxide) is one of the quintessential bleaches that is included as an active ingredient in many detergents and household items.

Thanks to its properties, it removes all types of dirt, including that which is formed due to the growth of fungi such as mold.

How to use?

  • Dilute a couple of tablespoons of sodium percarbonate in warm water and spread it over the stained areas.
  • Let it act for 20 minutes and rinse.

5. Grapefruit seed extract

Grapefruit seed extract is not that popular, but those who have tried it say it is an excellent cleaning agent.

Its antiviral, antibacterial and antifungal properties make it a great option against mold growth in the home. Also, unlike other solutions, it does not have strong odors.

How to use?

  • Dilute 20 drops of this extract in a cup of water and rub it on the mold stains.
  • Let it act and remove the dirt with a cloth. No need to rinse!

6. Vodka

Although it is one of the favorite drinks for the preparation of cocktails and drinks, vodka has other alternative uses thanks to its alcohol content. It fights fungi and eliminates the presence of bacteria from almost any surface. In addition, its assets remove mold and leave the walls impeccable.

How to use?

  • Spread a good amount of vodka on the stained walls and let it work for 10 minutes.
  • After this time, rub it with a sponge or cloth.
  • Use it multiple times to get great results.

Choose one, take the test and say goodbye to mold

Choose the method that most catches your attention and follow the recommendations given to achieve the desired effect.

In addition to this, keep in mind that it is essential to have some type of ventilation in humid areas to alter the environment that fungi require to proliferate.

How to troubleshoot mold on interior walls

Mold can be a major problem for homeowners. Besides the damage it can do to the infrastructure of your home, mold is a serious health risk. Even if you’re healthy, mold can lead to respiratory issues, skin problems, and headaches.

Mold doesn’t grow out of nowhere. When you start seeing signs of mold on your walls, it’s time to reassess the potential causes.

Most people understand that mold thrives where excessive moisture is present, but fewer realize how many opportunities there are for moisture to accumulate in a house. There are three common causes of the moisture that invites mold to grow, all of which are preventable with a little forethought.

Reason #1: Humidity

Humidity is the primary cause of mold on walls. If you live in a humid area, an easy solution is to purchase a dehumidifier, and move it to different rooms on a regular basis to ensure that all areas are adequately covered.

For larger spaces, it may be worth purchasing multiple dehumidifiers. Even homeowners in dry areas should watch out for appliances that use significant amounts of hot water, since this can make the surrounding air more humid even in an arid region. Clean behind your laundry machines regularly, open the windows when you shower in the bathroom or wash dishes in the kitchen—and make sure your home is well-ventilated at all times.

How to troubleshoot mold on interior walls

Reason #2: Condensation

Condensation occurs naturally on the perimeter walls of your home, which are often cooler than the air inside your house. As a result, the water in the air can experience a temperature drop when it touches these walls, and undergo a change of state to become liquid. If this liquid is left alone too long it will become an ideal breeding ground for mold.

Inspect any outside walls of your house regularly to prevent moisture buildup. It may also be worth installing double-stud walls, which all but eliminate the risk of condensation.

Reason #3: Water Leaks

The third most common cause of mold on residential walls is also one of the simplest: leaks. If your pipes drip, water is likely making its way into the framework of your house every time you turn on the tap.

As this moisture builds up over time, it becomes a potent hotbed for all kinds of bacteria, and mold becomes inevitable. Check your pipes frequently, and make sure that you take steps to keep them from leaking when the temperature in your area changes. Leaks often occur when winter arrives and the sudden cold warps the metal in your pipes, causing it to crack. Invest in insulation for your pipes, drain outdoor faucets before the water in them has a chance to freeze, and consider letting your indoor taps drip steadily overnight to keep the water in them moving.

Mold is a homeowner’s worst nightmare, but it doesn’t have to be yours. Use the tips listed in this guide to mold-proof your home, and you’ll be able to enjoy living in comfort and mold-free for as long as you want. The best part? Reducing risks of mold will ultimately increase the value of your home, and make it safer for your whole family.

Mold growing on any building materials exposed to moisture releases spores into the air that can create a health hazard in your home. The porous nature of drywall makes it an ideal substrate for mold growth, and once mold begins to grow on unprotected drywall paper, the drywall must be removed. If that becomes necessary, a thorough mold remediation should precede the installation of new drywall. It isn’t always necessary to replace moldy drywall, though, if it has been painted.

An Unseen Menace

You can instantly recognize the blackening mold causes, but it’s the mold you can’t see that is most damaging. It can grow on the back of drywall that has been soaked by a leak, and you know it’s there because you can smell it. There may be a colony behind peeling wallpaper or under drywall tape loosened by age or water. Once mold starts to grow on unprotected drywall paper, there’s no other way to stop it from spreading than removing and discarding the affected drywall. If the mold is growing on painted drywall, however, you can wash it off.

Replacing Moldy Drywall

You should hire a contractor with experience in mold remediation to remove moldy drywall, because this procedure releases spores. If you do it yourself, wear a respirator, gloves and goggles, and block any air intake vents in the room to stop the spores from broadcasting through the ventilation system. You should physically remove the mold from the framing by scraping and sanding before hanging new drywall, or it will grow back. You then need to soak the framing with a suitable disinfectant, such as a solution containing 1 part household bleach to 10 parts water. Finally, the framing must dry completely — use a fan, if necessary.

Cleaning Painted Drywall

You don’t have to resort to the same drastic measures to remove mold growing on the surface of painted drywall, because the paint seals the drywall paper. If you find mold growing on a surface coated with glossy paint, you can remove it by scrubbing it with a solution of liquid cleaning detergent and water. If the surface doesn’t have a high sheen, add 1 part bleach to 10 parts of the detergent solution and wash the paint thoroughly. Wear rubber gloves and avoid touching the mold with your bare hands so you don’t spread it and infect another part of the house.

Mold Prevention

You can’t prevent all mold from growing in your house, but you can limit it by controlling moisture. The ideal humidity for your home is between 30 and 60 percent, according to the EPA; if it’s any higher than that, you may notice musty odors that are the telltale signs of mold. Control excess humidity by opening windows and doors to increase ventilation or by operating a dehumidifier, especially if you notice condensation collecting on the walls. You also need to take fast action at the first sign of a leak to control and prevent mold — it takes mold 24 to 48 hours to begin growing on wet surfaces.

It’s the real-life monster that no one wants in their home. It’s the four-letter word that causes homeowners to scream in terror. It’s mold, and it’s a problem for many homeowners. For some people, indoor mold spores can cause symptoms ranging from sneezing and eye irritation to serious lung problems. The good news is that if detected early, mold can be safely removed before it becomes a catastrophe.

How do you know if it’s mold?

The bad news: Mold loves to hide. How do you find this evil house guest before it’s too late? Your nose knows.

Your sense of smell is the first line of defense against mold. You can often smell mold before you can see it. If you notice a musty smell in your home, there’s a good chance you have mold. If you think you have a mold problem, get on your hands and knees and smell the electrical outlets. As silly as it sounds, this is not a practical joke. Outlets have better access to the area behind walls, and smelling them can help pinpoint the mold problem. If mold is there, you’ll be able to smell it.

You should also investigate the areas in your home where mold loves to hide. Basements and bathrooms are likely places, but check out our infographic revealing the six secret places mold loves to hide: chimney, roof, windows, washing machines and under wallpaper.

If you’re still not sure, it’s time to call in a professional. Professionals can test the air for mold spores and determine if and exactly what type of mold is present.
