How To Test For Mold In Drywall

Spotting And Fur On Your Walls

How To Fix Rotten Moldy Drywall From Water Damage! DIY For Beginners!

There are so many varieties of mold that you cant really identify the type based on specific shape, size or color. It can appear as a furry, dark growth, as a black stain, or as black, white, orange, green or brown specks. Rather than look for out-of-the-ordinary, multi-colored flakes in every inch of your home, identify areas that are moist and then look for possible signs of mold. The fungus thrives in cool, damp areas, and it will be much easier to find it by limiting your search to areas that are affected by excess moisture. Yes, paint and wallpaper gets stained and marked from every day living, but if you see a pattern to the stains, or they appear in the corners of a room, this is usually a good indicator that mold is present.

Can Mold Spread From One Apartment To Another

Unlike houses, apartments are not usually self-contained living environments. Apartments exist as interconnected units with common ventilation and plumbing systems.

As a result, if one apartment has a mold and mildew problem, it can easily spread to other apartments through the air in HVAC systems.

This means that even if you remove mold from your apartment, it could still come back if other apartments in the building remain contaminated. In addition, its very difficult to find the source of the contamination especially if you dont have the help of a professional mold inspector.

Why Is A Mold Inspection Almost Always Unnecessary If There Is Visible Mold

Dont you need to know what kind of mold it is so you can determine whether its toxic? No. For starters, so called Black Mold is a term that is badly misused and misunderstood as we already discussed in our other industry shakeup article on toxic black mold.

Secondly, once you already see obvious, visible mold, knowing what type it is is usually irrelevant because at this point, you or a mold professional simply need to get rid of the mold following proper Mold Remediation and Mold Removal Principles.

Doesnt the type of mold matter in determining the right way to properly remove the mold? No. In fact, once visible mold is present, the same Mold Remediation Principles referenced above are followed to remove it regardless of the color, species, etc.

If this all sounds too hard to believe, especially coming from a mold company, dont take our word for it. Here is what the Environmental Protection Agency says verbatim:

Notice the EPA says that not only is mold testing usually unnecessary when visible mold is present, but they also tell you that there are no federal guidelines for determining the amount of mold spores that is safe or dangerous. This is also something we tell our clients all the time, and by now you can probably guess is a rather important fact that most other companies will of course not bother to reveal!

Remove Mold From Drywall/painted Walls

Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.

How To Remove Mold Behind Walls

A lot of people falsely believe that killing mold inside walls is an easy process. Its not. This is NOT a DIY activity. One wrong move and you run the risk of contaminating your entire home and all of your belongings. It is better to spend the money and allow a professional to properly remediate the area than trying to do it yourself and causing a larger, more expensive problem.

When it come to mold, you want to do it right. That means opening up walls, removing the moldy building materials and replacing it with new building materials. Specifically, porous materials such as sheetrock and insulation should be replaced. Even though the sheetrock and insulation may appear to be OK, it is likely that mold spores are still present and the mold may continue to grow even if you follow a treatment of black mold inside walls. It also means treating the areas around it with products like EC3 and Endurance Bio Barrier to tackle any rogue mold spores and mycotoxins and prevent mold in the future.

Mold in walls is one of the more complicated mold scenarios but certainly one that can be handled. Please reach out if you think you have mold hiding inside your walls. I offer phone consultations on the best steps to take for your individual situation.

How To Identify Black Mold On Other Surfaces

How To Drywall A Bathroom | Church Flip | Episode 15

Black mold has a distinct look that should signal to you its presence on other surfaces in your home. It may look dark green or gray, depending on where it is growing. It also may simply look like black, fuzzy spots growing in dark and wet corners of the floor, ceiling, walls and other areas.

If other surfaces in your home have been exposed to moisture, humidity or water and have this type of growth on them, you should suspect that the spores are actually black fungus. The spots may even be difficult to sweep or scrub and only be removed and killed if you spray bleach or ammonia on them.

Why Is Mold Such A Problem

Firstly, why is mold on drywall seen as such a problem?

Firstly, there are some variants that are harmful to you. This is especially true if you have allergies, as the spores can aggravate symptoms for you. When thats in your home, there really is no getting away from it. If you tackle mold as soon as you find it, then youre going to keep any effects on your health down to a minimum. Its especially important if you have children in your home, as they can be especially affected by mold.

Second, if you see mold in your home, then it can be a sign that something else is wrong in your home. Mold often shows up when theres poor ventilation in your home, especially in areas that can get hot and steamy, such as your bathroom. If youre seeing it there, its a sign that you need to tackle the cause of the mold, or its not going to go away for good.

Finally, mold will also cause all kinds of damage to your drywall if left to its own devices. If its growing, its eating into the wall and damaging it as it goes. The longer its left, the more damage it will do. It can even destabilize the wall if its left long enough. The sooner you tackle it, the less damage youll have to handle once its gone.
