Why Is There Mold Growing on Walls in My House?Mold is not a fun thing to find in your home or office. If you’ve ever dealt with mold growth before, you know that getting rid of it is definitely not the easiest thing in the world. You probably tried a lot of different do-it-yourself methods, working tirelessly and endlessly to get rid of the nasty and inconvenient growths on your walls. Maybe, the mold was close to the top of the wall, near the ceiling. Or, perhaps, it was growing near the bottom corner. In either case, getting rid of the mold was quite a task. If you have not had to deal with it before, then you are probably wondering what to do about the mold growing on walls in your house or business. Where did it come from? How did it get there? What should I do about it? How do I get it out of here?

You might be asking those questions, trying to figure out exactly why and how the mold came to appear on the walls of your office or house. After all, you didn’t really notice any signs or indications that there was a problem until, well, the problem appeared. You are probably aware that mold doesn’t just simply show up. The conditions have to be just right in order for mold to grow and spread in your home. But, of course, now you are wondering how your house became a good place for mold to flourish. Perhaps you are thinking, “I keep my house so clean! Why would mold be able to grow there?” Many people equate mold growth to dirt. A lot of individuals feel that mold in the house or office is a sign of uncleanness. But, this actually isn’t the case. And we’ll talk more about that in just a minute.

How Did Mold Get Into My Business or Home?

Why Is There Mold Growing on Walls in My House?Alright, let’s take a stab at the first couple of questions. Many times, people are unsure about whether or not there is really mold growing in their homes. Some choose to first test for mold before they invest in a remediation service. But, honestly, if you are already seeing even the smallest amount of growth, it’s pretty safe to say that you can skip that step. If there is already a sign of mold in your home or workspace, there’s probably more where that came from and it’s not necessary to test for mold. Your best bet is to get a professional to take a look at it as soon as possible.

One of the main things you might be wondering about right now is how in the world that stuff got on your walls! How did you end up having mold grow on walls? Well, here’s the first thing you should know: mold can grow anywhere. Yeah, we mean anywhere. As long as the conditions are right, that nasty fungus can develop. So, yes, that includes the walls. But, of course, your next thought may be to ask how the walls provided a comfortable spot for mold to rest. We’ve got an answer for that, too!

You see, mold likes moisture and humidity. It can grow in cold climates, too. But, the main reasons you might see mold growing on walls is the humidity and wetness. Usually, the moisture is the result of a leak of some sort. Perhaps, there is a leak from the ceiling. Maybe, a toilet or sink is leaking. Whatever the source may be, the moisture can cause mold to form. Condensation is also a contributor to the growth of mold on your walls. This condensation forms as the result of water vapor in the air meeting the coolness of the walls. When this happens, the vapor turns from a gas into a liquid. And voila! You’ve got a perfect place for mold to find rest.

More Information About Indoor Mold Growth

Why Is There Mold Growing on Walls in My House? Before we talk about what you should do if you see mold growing at your job or in your house, we should discuss some details about the mold. First of all, what color is the mold on your walls? What does it look like? The way the mold looks can indicate what kind of mold it is. This information can help you to determine the best way to treat the problem. Some mold types that are often found on walls include:

  • Aureobasidium: pink, black, or brown in color
  • Fusarium: red, pink, or white in color
  • Penicillin: Greenish or bluish in color
  • Trichoderma: White with green patches

These mold types tend to be attracted to drywall, wallpaper, and painted walls. It is not uncommon to find these molds growing behind wallpaper. So, as we said before, if there are visible signs of mold, there is most likely more mold growing somewhere out of your sight. There could be more mold behind the walls and underneath the surface of what you see. This is why it is so important to work as quickly as possible to stop mold dead in its tracks. You don’t want to just paint over the mold or kill the surface growth. A safe mold remediation process can help to get to the heart of the matter, ending the problem with efficiency and thoroughness.
