Did You Know...
...that approximately 45 million buildings in the United States have unhealthy levels of mold? Do you currently have mold behind the walls or mold in the ceilings of your home? Do you suspect that this might be an issue for you?
If you're concerned about mold in walls or other areas of your house, keep reading. Explained below is everything you need to know about how to detect mold behind drywall.
What Causes Mold Growth?
When you first spot mold growing in your home, or start suspecting that it's growing, you might think something like, "How did that get there?" or "What did I do to cause mold growth in my house?"
There are plenty of ways that mold can find its way into your house. For example, spores can enter through open windows, doorways, or your ventilation system. They can also attach themselves to shoes, clothing, or pets and find their way in through these different vehicles.
It's important to note, though, that mold will only grow and spread in areas that are favorable. This includes areas that are very moist and provide the mold spores with a steady supply of nutrients.
If you have a leaky pipe or flooding in your home, for example, that will create a prime area for mold growth. Places with excessive window condensations might be prone to mold, too. The same goes for spots that don't get a lot of air circulation.
Why Is Mold Growth an Issue?
You know that mold growth is unsightly. Do you truly know how potentially dangerous it is to you and your family members' health, though?
The following are some of the most significant health risks that come with long-term mold exposure:
- Allergy symptoms (stuffy nose, runny nose, throat irritation, eye irritation, etc.)
- Headaches and migraines
- Confusion and brain fog
Breathing in air that's full of mold spores can also increase your risk of developing certain chronic illnesses. This includes chronic sinus and respiratory issues.
How to Detect Mold Behind Drywall
Okay, you're convinced that you need to take mold seriously. How do you know if mold is an issue in your home, though?
The good news is that there are lots of steps you can take to detect mold behind drywall or in other areas of your house. This includes the following:
Check for Stains
Looking carefully at your walls can tell you a lot about what might be going on behind them. Do you notice any yellow or brown stains? If you have water stains on your walls, there's a good chance that you likely have mold growing behind those stains.
Keep in mind that mold will look different depending on what's on your walls, too. For example, if you have vinyl wallpaper, the mold might look pink, purple, or orange in color. If you notice this kind of discoloration, that's another sign that you have a mold growth problem.
Look for Surface Changes
When there's mold growing behind the walls, the appearance changes quite a bit. Not only will you notice color changes, but you might also find that the walls themselves start to deteriorate.
For example, the paint might start to crack or peel, or the wallpaper might bubble due to excessive moisture and mold spread. Your walls might start to warp, too, or even bulge or bow when the damage gets very bad.
Sniff It Out
Often, when mold is growing in your home, your nose will let you know. Mold has an earthy, musty odor. Many people compare it to the smell of a damp forest (this is nice when you're out camping, but not so much when you're hanging out at home).
The smell of mold is often especially strong in the area around your electrical outlets since they provide access to the space behind the walls. Get down and sniff around here to see what you can smell.
Try the Screwdriver Test
The screwdriver test helps you to pick up on potential surface changes in your walls. Take a screwdriver and probe the wall where you suspect mold might be growing.
If the wall feels soft or if it starts to crumble when poked with the screwdriver, that's a sign that you likely have mold growth and, additionally, are experiencing rot from excessive mold growth and spread.
Use a Mold Test Kit
You can also use a mold test kit to determine whether or not you have mold growing in your house. These kits are available at most hardware stores, or you can purchase them online.
Keep in mind, though, that they're not always accurate. Using a kit could be a good first step, and you can then follow it up with some of the other tactics mentioned above.
What to Do if You Discover Mold
If you follow the steps listed above and find mold growing in your basement or another room in your home, it's important to act quickly before it can spread further.
Failure to address the problem could lead to expensive and potentially dangerous structural issues in your home, as well as worsened health problems.
Generally speaking, mold removal is a job best left to mold remediation professionals. Calling an expert will help you to identify the root cause of the mold growth and ensure you're totally eliminating mold from your home.
A professional will also be able to take steps to prevent mold from growing in the future.
