How To Test For Mold In An Apartment

Dec 06, 2022

If you live in an apartment, you know how quickly these environments can become humid and lack proper airflow. Mildew and mold spores are abundant in these conditions, and they tend to thrive in dark, moist places with limited airflow.

If left alone, these spores can grow into colonies of mold, which release their own volatile organic compounds as byproducts. These VOCs make mold so unhealthy for humans because they’re toxic when inhaled or ingested.

If you suspect that your apartment has mold growing somewhere on the premises (or within your home), it is crucial that you take action as soon as possible. If left untreated for too long, mold will expand to other parts of your property and make it uninhabitable. Here’s how you can test for mold in your apartment:

Check for Visible Signs of Mold

If you aren’t sure if there’s a problem, the first thing you should do is check for visible signs of mold. These are often characterized by black or gray spots that appear on the walls, floor, ceiling, or other porous surfaces.

If you notice these, you should definitely have your apartment tested for mold because it is present. 

What you want to search for are the little pustules that appear on surfaces when mold is present. If you find spots of mold, it’s best to have your apartment tested for levels of mold spores. Otherwise, you run the risk of having the mold spores spread throughout your living space.

Common Places To Check For Mold

There are several different places in your apartment where you can look for signs of mold. Keep in mind that these can be more obvious if you’re dealing with a massive mold outbreak, but they may also be evident if there’s just a small amount of mold growth. Here are some common places to check for mold:

  • Behind your refrigerator: The backside of your refrigerator is one of the most humid places in your apartment. If moisture is allowed to accumulate there, it can quickly foster the growth of mold.
  • Around your shower or tub: If you have a bathtub or shower in your apartment that isn’t properly sealed, water can seep behind the walls and collect. If this water sits there long enough, it can become a breeding ground for mold.
  • Behind light fixtures or air vents: Similar to behind your refrigerator, these areas can become damp and moldy if they’re not properly sealed.
  • Underneath your sink: As with behind the refrigerator and above your bathtub, under your sink can become humid and moldy if not properly ventilated.

Consider the Smell and Odor

Considering the smell and odor that surrounds your living space is another way to test for mold in your apartment. Mildew and mold produce distinctive smells that many people associate with the smell of stale or wet clothing.

If you smell something like this, it doesn’t necessarily mean you have mold, but it can be a sign that you need to clean up some areas of your home. If you smell a strong musty smell in your apartment, this might be a sign that there’s mold in your home.

The smell of mold spores is best described as a "musty" smell. This smell can be difficult to detect if you have a normal level of indoor air flow. If you smell this in your living environment, it’s a good idea to have your apartment tested for mold spores.

Examine for Water Leaks

One of the easiest ways to test for mold in your apartment is to look for signs of water leaks. If you have a leaky roof or plumbing leak that isn’t being properly dealt with, mold will grow in these damp environments.

If you notice damp spots on the wall or ceiling that don’t dry up, there’s a good chance that you have a leak. You may also notice that your apartment is generally humid, even when it’s not humid outside. If you feel that the air inside your apartment is consistently moist, there’s a strong chance that you have a leak.

Check Your Overall Health

Another way that you can test for mold in your apartment is to look at your general health. If you’ve been experiencing any sort of respiratory issue or feel like you’re always coming down with a cold, mold could be the cause.

Mold spores are what cause most of the health issues that come from living in a moldy apartment. If you notice that your health has been declining steadily since moving into your apartment, there’s a good chance that mold is the cause.

You can also give your overall health a boost by cleaning up potential mold issues in your living environment.

Confirm Your Findings With A Mold Test Kit

If you want to be sure that you have mold in your apartment, you can buy a mold test kit. These kits are easy to use and affordable, and they will provide you with plenty of information about the type of mold that is in your apartment.

They’re also useful for landlords and property managers, as they can help them determine the extent of the mold problem. A mold test kit will tell you how much mold is in your apartment, what species it is, and how much VOCs it emits. It will also let you know whether your apartment is clean enough to return to living in it or not.
