TREATMENT OF MOLD INSIDE WALLS
HOW TO DETECT MOLD IN WALLS
Cleaning mold on visible surfaces may not be easy (especially if it’s a major infestation) but it is very much possible even without the help of mold remediation experts. Of course, it is more advisable to seek professional help when treating black mold on walls but if there’s a minor build-up on your walls, floors, or ceilings, you can get rid of it using common tools and cleaning supplies that you may already have at home.
But what if the infestation is inside your walls? How do you even know it’s happening?
Before you learn how to remove mold inside walls, you must learn how to detect it. Take note that mold spores are super tiny and not visible to the human eyes so they can spread throughout your house discreetly. And until you know the signs of mold build-up, the black mold could already be damaging your property and you are still clueless.
Alright. So how can you tell if the black mold is hiding inside your walls?
If you’re like most homeowners whose walls are made of gypsum walls, also called “drywall”, you might be curious to know whether there’s mold build-up inside. Experts recommend several ways:
Cut a large hole on your wall. This is perhaps the most definitive way of determining whether there’s mold inside your walls. If there is, you will be tearing them down anywhere. However, there are drawbacks to this approach. First is that using a drywall saw can damage any electrical or plumbing systems if you unknowingly drill them. Be sure to have some plastic sheathing ready to cover that hole afterward.
Perform a smell test. The second method is to sniff around electrical outlets. If the mold is actively growing, it produces microbial volatile compounds which are the musty, earthy odor released by the mold. Electrical outlets and other openings provide you with more direct access to the odors inside your walls. If you smell the musty odor through them, there’s likely a mold infestation. The drawback of this approach is that you may not find any electrical outlet or opening on the walls you suspect are damaged or infested by mold. You may also find it hard to determine the extent of the mold build-up as if it’s just around the outlet or far from the outlet.
Check for moisture problems. When there is a moisture problem, then there is most likely mold build-up. If you see water stains on your walls or if a part of your walls has sustained water damage and it has been there for quite some time, there’s a big possibility of mold.
Hire pros to test for mold. This might come with a price but it’s the safest and most effective way to tell whether there’s mold lurking inside your walls.
Now that you know how to spot mold, it’s time to learn about how to kill black mold on walls.
REMOVING MOLD FROM WALLS
Depending on the severity of the infestation, cleaning mold from walls may or may not require help from the professionals. Basically, removing mold behind walls is the same as how to treat mold on wood studs. If the mold build-up is on the outer surfaces of your walls, you can safely and conveniently get rid of it using a few solutions like detergents, vinegar-baking soda, or commercial cleaners (find more info here). But getting rid of mold inside walls is a different thing. It involves tearing down the wall and replacing it. It is best to leave it in the hands of professional mold remediation contractors as doing it by yourself could lead to the possibility of drilling or grinding through electrical or plumbing systems.
So how do you remove black mold from walls?
- Prepare your cleaning solution.
- Scrub the mold off using your cleaner and water.
- Dry the area. Open doors and windows to allow air to circulate.
- Use a dehumidifier to reduce moisture problems and prevent mold from growing back.
- If the mold infestation is inside the walls, you will need to hire professionals as there’s a need to knock down the walls and replace them.
HOW AND WHY MOLD GROWS ON WALLS
You’re here because you are eager to learn how to get rid of mold in walls. But you might be curious to know – how come mold grows on walls? There are a number of reasons why:
Humidity – this is the primary cause of mold problems inside homes. If you live in a humid area, it is advisable to purchase a dehumidifier and move it regularly to different parts of your home to decrease moisture content in your indoor air.
Condensation – this occurs naturally in the perimeter walls of your home, which is cooler than the air inside your house. When the water in the air experiences a temperature drop as it touches the walls, condensation takes place (moisture is turned into liquid).
Water Leaks – another common cause of black mold in walls are water leaks coming from different sources, such as holes in the roof or cracks on plumbing systems. It is important to check pipes regularly and takes steps to keep them from leaking.
